  1. Originally written by Rgoer Title: Terrain Creation in EasyGen Subject: How to create terrain using EasyGen Written by: Rgoer Tutorial written for: JK2/3 Similar concept work like in: Hand-Shaped Terain in Radiant. Difficulty level: 4/10 Expected time to complete for first attempt: 30mins Prerequisites:Basic proficiency in JK3 modding and radiant. Download EasyGen (as of this writing, version 1.42 is the most recent) This version INCLUDES the custom rgoer templates...but don't fire EasyGen up quite yet. Before we get going, we need to create a heightmap. A heightmap is just a greyscale bitmap file, where each pixel defines the elevation of one brush vertex of EasyGen terrain. This is an example of a heightmap: When you paint your own heightmap, you need to keep in mind that your heightmap needs to be one pixel wider in every dimension than the number of terrain brushes you want to make up one "side" of your terrain "square." For example, I wanted a 48-by-48 terrain, so I painted that example heightmap to be 49-by-49 pixels. This is because each heightmap pixel corresponds to a single brush vertex, and the vertex count is always one more than the brush count (one single brush has two vertexes per side). Anyway, heightmaps aren't that complicated: brighter pixels represent higher elevation, and darker pixels are lower. White is the highest, black the lowest. If you have access to landscape software like Bryce or Terragen, you can export some nice heightmaps from those programs... The only important peculiarities about EasyGen heightmaps is that they must be greyscale (8/16/24 bit all work fine), and they must be in Windows Bitmap (*.bmp) format. Now it''s time to fire up EasyGen... When you first start EasyGen up, you''ll probably see something like this: Now is a good time to familiarize yourself with EasyGen''s 3D view controls. For the most part, you can move the camera with the same controls you use in Radiant. You also can drag the camera on the x/y plane with the right mouse button, and orbit with the left. Once you feel comfortable with EasyGen''s camera, feel free to move on. As with any new software, one of the first things you want to do is check out the preferences. This tutorial was written with Star Wars Jedi Knight: Jedi Academy in mind, but you can alter the JA specific stuff here to work with whatever game you please. Here is how you should set your preferences up to work with JA: Hit "OK" to save your changes to the preferences; now it''s time to import our heightmap: You'll be confronted with a "Bitmap Import Setup" window. Hit the "Browse..." button and find your heightmap, then set the height to something larger than the default 256 units... however tall you had in mind when you painted the heightmap, something in the 1024 to 2048 range generally works for most cases. Now, once we've imported the heightmap, we should see something along these lines: And now the important stuff... All of the EasyGen magic happens in the "Alphamap" tab... so let''s head that way: We need to load some textures in order for EasyGen to have something with which to work its wonders... if you're working with JA, and you want to use default JA textures, you''ll need to unpack some from assets1.pk3 (in base). After you've done that, choose "Add folder..." from the "Textures" menu: In the little browser, navigate to whatever texture directory you want to work with; I chose the "desert" set that I unpacked from assets1.pk3. At this point, notice that EasyGen tells you exactly what to do, right on the screen: Click the first black square, pick a color, then choose a texture from the textures well. Oooh, ahhh; hit the little brown and green button I have circled in that image, and you''ll see that the terrain is now covered in the texture you just picked. Now you want to create a palette of more color/texture combinations. Pick as many textures as you think you'll want to blend together on your terrain. Set your brush size with the "Paint radius" slider, and go to town painting on your terrain by holding ctrl+shift and using the left mouse button. Keep this in mind: Quake III (and, by extension, any Q3-engine game) can only blend at most TWO textures on a single surface triangle. EasyGen knows this, and warns you if you start creating three-way (or more than three-way) blends by turning the offending triangles black. If you start noticing triangles going black, it means you are trying to blend too many textures on a single surface, and you need to go back and repaint your blends until you have, at most, two textures blending on any given surface. And now we wrap things up... Eventually, you''ll end up with something like this: Once you're satisfied with how your terrain looks (and you''ve remedied any black-triangle blending errors), you're ready to hit the "Export Terrain Entity" button (circled in red). You''ll be greeted with the "Radiant .map and related stuff settings" window... you want to set it up following this example: It is key that you installed the "rgoer" templates correctly, and that you added "rgoer" (without quotes) to the templatelist.txt file. Also, note that I used the name "tutorial" for all my map-specific names; you will want to use whatever the name of your map or project is in those instances. The alphamap should be saved to the base directory; just click the little "..." button and give it a name. This creates a .pcx file that indexes which textures should be placed where by the compiler. The shader should be saved to the scripts directory; EasyGen was designed to work with Quake III: Arena, and this is a throwback to that game. We'll move the shader file to the shaders directory in a minute. Lastly, make sure that you put "system/terrain" in for the "top" and "system/caulk" in for the "sides" of your terrain brushes. This is a must (pretty much everything on this export settings screen needs to be set up just right, or your terrain blending won''t work). Now you're ready to hit "Continue >>", give your terrain map a name, and let it rip. Now we're really getting there. Move your .shader file from the scripts to the shaders directory, and open it up in your text editor; there is one small change that must be made by hand, due to a bug in EasyGen. Down at the bottom of the shader defitions, the very last one should be a definition for a shader called "terrain_base." This is the shader called by all the q3map_baseshader lines in the rest of the shader file, so it should be first (not last). Select this shader, cut it from the end, and paste it back in at the top so that it is the very first shader defined in your .shader file. Save it and you''re done. Finishing Up: All you have to do now is add your shader file to shaderlist.txt and copy/paste your terrain entity from the .map EasyGen created into whatever .map you''re working on. You don't want to use the .map created by EasyGen, because it puts a bunch of garbage into the worldspawn that makes the .map unusable. The terrain entities (which are really just func_groups) are fine, though, and you can just select the terrain, copy it, and paste it into whatever .map you want to, or load the map as a prefab into a new map.
  2. Creating a Skybox using a JKA Map Szico VII Title: Creating a Skybox using a JKA Map Subject: How to turn a 3D scene created in Radiant for Jedi Academy into a Q3 skybox using a little script trickery. Written by: Szico VII Tutorial written for: JK3 Similar concept work like in: N/A Difficulty level: 03/10 Expected time to complete for first attempt: 5-10 minutes Prerequisites: JA SDK and BehavED installed, knowledge of map creation and compiling, ideally a monitor that supports resolutions of 1024x1024 or greater. Getting started: First off copy the code below into a txt file and save it into base/scripts. //Generated by BehavEd rem ( "Skybox Screenshot Script" ); camera ( /*@CAMERA_COMMANDS*/ ENABLE ); camera ( /*@CAMERA_COMMANDS*/ MOVE, $tag( "cam1", ORIGIN)$, 0 ); rem ( "===========================" ); rem ( "sky_rt" ); camera ( /*@CAMERA_COMMANDS*/ PAN, < 0.000 0.000 0.000 >, < 0.000 0.000 0.000 >, 0 ); affect ( "player", /*@AFFECT_TYPE*/ FLUSH ) { sound ( /*@CHANNELS*/ CHAN_VOICE, "sound/chars/r2d2/misc/r2d2talk03.mp3" ); } wait ( 4000.000 ); rem ( "===========================" ); rem ( "sky_bk" ); camera ( /*@CAMERA_COMMANDS*/ PAN, < 0.000 90.000 0.000 >, < 0.000 0.000 0.000 >, 0 ); affect ( "player", /*@AFFECT_TYPE*/ FLUSH ) { sound ( /*@CHANNELS*/ CHAN_VOICE, "sound/chars/r2d2/misc/r2d2talk03.mp3" ); } wait ( 4000.000 ); rem ( "===========================" ); rem ( "sky_lf" ); camera ( /*@CAMERA_COMMANDS*/ PAN, < 0.000 180.000 0.000 >, < 0.000 0.000 0.000 >, 0 ); affect ( "player", /*@AFFECT_TYPE*/ FLUSH ) { sound ( /*@CHANNELS*/ CHAN_VOICE, "sound/chars/r2d2/misc/r2d2talk03.mp3" ); } wait ( 4000.000 ); rem ( "===========================" ); rem ( "sky_ft" ); camera ( /*@CAMERA_COMMANDS*/ PAN, < 0.000 270.000 0.000 >, < 0.000 0.000 0.000 >, 0 ); affect ( "player", /*@AFFECT_TYPE*/ FLUSH ) { sound ( /*@CHANNELS*/ CHAN_VOICE, "sound/chars/r2d2/misc/r2d2talk03.mp3" ); } wait ( 4000.000 ); rem ( "===========================" ); rem ( "sky_dn" ); camera ( /*@CAMERA_COMMANDS*/ PAN, < 90.000 0.000 0.000 >, < 0.000 0.000 0.000 >, 0 ); affect ( "player", /*@AFFECT_TYPE*/ FLUSH ) { sound ( /*@CHANNELS*/ CHAN_VOICE, "sound/chars/r2d2/misc/r2d2talk03.mp3" ); } wait ( 4000.000 ); rem ( "===========================" ); rem ( "sky_up" ); camera ( /*@CAMERA_COMMANDS*/ PAN, < -90.000 0.000 0.000 >, < 0.000 0.000 0.000 >, 0 ); affect ( "player", /*@AFFECT_TYPE*/ FLUSH ) { sound ( /*@CHANNELS*/ CHAN_VOICE, "sound/chars/r2d2/misc/r2d2talk03.mp3" ); } wait ( 4000.000 ); camera ( /*@CAMERA_COMMANDS*/ DISABLE ); Then open it up in BehavED and compile it into an IBI file. Then, you must make a ref_tag in your map where you wish the "camera" to take pictures from, and have a spawn point trigger link to a target_scriptrunner which activates this script. Give the ref_tag a targetname "cam1" COMPILE THE MAP (Duh.) Load up Jedi Academy SINGLE-PLAYER mode. Open the console and (depending on your maximum screen resolution) set a custom resolution of 1024x1024 or 2048x2048 using the following commands: r_mode -1 r_customheight 1024 r_customwidth 1024 vid_restart (You can also try cg_fov to get different results) NB: You could use values in-between, say 1600x1600 pixels, just be aware you'd have to re-size them afterward to 1024 or 2048 pixels. Now run your map using the /devmap mymapname command. It will boot into a cutscene - Your job is to take a screenshot (bind it to a number key, say "2") every time the view changes, without allowing the 'screenshot xxx taken' message to ruin your lovely pictures. The script will show you 6 views from the point you placed your ref-tag, which you can then use as your 6 skybox images. It will make a beep noise as it changes view, and it changes every ~4seconds. Now rename the screenshots to skybox_bk, ft, lf, rt, up and dn as appropriate. VOILA. Examples:
  3. Creating Curved (Corner) Cylinders Szico VII Title: Creating Corner Cylinders Subject: How to create bends in pipes, t-junctions and corner pipes Written by: Szico VII Tutorial written for: GTK Radiant 1.4.0 Similar concept work like in: N/A Difficulty level: 3/10 Expected time to complete for first attempt: 5 mins Prerequisites: Ability to construct cylinders and use the grid Creating Curved (Corner) Pipes In order to create a ''curved'' pipe, which is basically a corner junction for two other pipes, you'll need to know a little bit about radiant and be able to effectively use the grid-snapping. However, this isn't too hard, and after a while you should be able to do it easily. So let's get started! Firstly, make sure the ''Snap to grid'' option is turned on. You can do this by going to the ''Grid'' menu at the top, and then selecting ''Snap to grid.'' This (when turned on) will have a small tick next to it. This is important, as the curved patch involves editing vertices, which will deform the patch if a point is even one unit out of place. Therefore it is best to work to a large grid-size, and then resize the patch afterward. So set your grid-size to 256. (Again, under the grid menu.) Now, you'll want to create a cubed box, with all it's dimensions the same. With the box selected, hit the ''Q'' key to bring up the measurements, and be sure each side is the same width (swap between views in radiant by pressing Shift+ Tab) Obviously, you can also easily tell by looking at the grid units in radiant, but when working with smaller grid sizes, this is a good check. Now, select the cube, and go to the ''Curve'' menu, then select ''Cylinder.'' This will turn your cube into a cylinder. Rotate if necessary, until the side of the cylinder (i.e not the top circular bit) is in alignment with the original cube, as shown below: Now we need to start editing the vertices, so make sure the cylinder is selected and hit the ''V'' key. 9 Points (vertices) should show up on the 2D view, as shown below. Ok, now we need to move these vertices around in order to create the curved pipe. Start by clicking the middle-right point (vertex), and dragging it up to the top-right vertex, so both the middle-right and top-right are now in the same place, as shown below. Note that you may need to change the gridsize down to 128 in order to align both properly. Note how I've decreased the grid-size (in the second picture, to 128, in order to put the point in the right place.) Next we need to move the bottom-right vertex, up to the middle-right point (which we had previously moved to the top.) The images below illustrate how it should be done. Now we need to move the middle-bottom vertex to the middle-right point. Just follow the diagrams below if you're unsure. Nearly there! Okay, now take the bottom-left vertex and move it to the bottom-right point, as shown below: You'll notice it doesn't look quite right as it is, but don't worry, there is still one more vertex to move. Click the middle-left vertex and move it to the bottom-left point: And there you go, a curved (corner) pipe. Feel free to resize it if need-be, and remember, when changing patch vertices, always try to stick to the grid, or you'll end up with some nasty results where things don't quite line up properly Feel free to texture your pipe now - hit ''V'' again to come out of vertex-editing mode, then select the pipe, choose a texture. Creating T-Junction Pipes Firstly, you'll need to create three identical cylinders with equal width, height and length. Place them as shown below: The gap between the three cylinders should be the same size as the cylinders i.e if you made a fourth cylinder it would fit into the gap perfectly. Okay, again press ''V'' to go into Vertex-Editing mode. Again put your grid-size down to 128, from 256 (or the one below whichever scale you are currently working at) so that you can place the points correctly. Firstly, select the lower cylinder (which is not in line with the other two.) and select the Top-Middle vertex. Drag it up to the centre point of the gap above, as shown below. Now you need to do the same thing with the other two cylinders, with the left hand one, drag the middle-right point to the centre of the gap, and with the right hand one, drag the middle left point to the centre of the gap, as shown below. Finally, you should take the top-right point of the left hand cylinder, and the top-left point of the right hand cylinder, and drag each vertex (separately though, not at the same time, or it won't work.) Into the top-middle point of the gap, as illustrated below. Texturing this junction effectively can be a bit of a pain in the arse, so have a few experiments and see which things fit best for the pipes. You CAN resize this construction, however you need to resize each cylinder separately, or it will go wrong. Don't try selecting all three cylinders and re-sizing. Rotation is fine and you can use it for this construction as you would a set of brushes. Creating Hollow Pipes So now you know how to create curving cylinders and T-junctions. But what if you want a hollow pipe? One that a player can walk through or one which has an opening to look into? To do this, the edge (or wall) of the pipe needs to be given depth, which a single patch on its own does not have, as it only essentially has one face, unlike a brush. In order to accomplish this, we must use several patches - one for the outer surface of the pipe, one for the inner surface of the pipe, and one to cap the end of the pipe, joining the inner and outer surfaces together. So here is how you go about it. For the purposes of this tutorial and for learning, follow the exact design of the pipe shown here - but remember you can of course change the dimensions, thickness and size of any of the components once you are familiar with the construction process. Firstly, create a brush that is 512(W)x512(D)x256(H) units in radiant. You can press the Q key to have radiant show you the units. I'm am using Grid size 64 for this tutorial - because remember, the vertex movements must be precise and having them even a single unit out of place will cause misalignment. Then make sure you are looking at the brush from the top-down view in radiant (XY view) Now select your brush, and go to the menu: CURVE -------> CYLINDER. This will convert your brush into a cylindrical patch mesh as shown below Now create a second brush in the center of the cylinder with dimensions 256x256x256. Repeat the process to convert this into a cylindrical patch mesh, as shown below: Once this mesh has been created, you need to invert its surface so the textured side is facing inwards. With the smaller cylinder selected, you can do this with the keyboard shortcut Ctrl+I. Alternatively, you can go Curve----->Matrix------->Invert. Your construction should now look like this: Now we have both the inner and outer surface of our hollow pipe. The next job is to cap the end off so it will appear to the player in-game that the pipe has true thickness. This is done using a different type of patch, the 'simple patch mesh.' Capping the Pipe Create a third brush (of any depth, it does not matter) which spans the distance between the outer and inner cylinders vertically, and the far right edge of the outer cylinder horizontally, as depicted below: Now, with this brush selected, turn it into a simple patch mesh as follows: Curve------>Simple Patch Mesh. (Alternatively use the shortcut Shift+P) This will bring up a small menu labelled 'Patch Density.' You will want to leave the values as they are, at 3 for width and 3 for height. (This determines the number of vertices used to control the patch. You should always use the minimum number possible for the construction required, for simplicity. Click 'OK' and you should now have a simple patch mesh that looks like this: Press the 'V' key to enter vertex editing mode. Your patch should have 9 vertices. Now we must move these vertices, as in the previous sections, to align this patch between the inner and outer cylinders around the top right quarter of the shape. Firstly, select the Bottom-Right vertex and move it 2 grid boxes (128 units on a 64-size grid) below the Bottom-Middle vertex, as shown below. Next, select the Middle-Right vertex and move it 1 grid box to the right of the vertex you previously moved: Then, select the Top-Right vertex, and move it 1 grid box to the right of the previous vertex you moved. Next, select the Top-Middle vertex, and move it to where the Top-Right vertex originally was (2 grid boxes to the right): Finally, move the Middle-Center vertex to where the Middle-Right vertex originally was (2 grid boxes to the right): Your construction should now appear as shown below: Now, the only thing left to do is to duplicate your patch (Ctrl+C) and paste it (Ctrl+V.) Then rotate the new patch mesh 90 degrees using the z-axis rotate tool, and repeat the copy and rotate twice more until the entire edge has been capped. Then all you have to do is apply your textures (Shift+S). Use the 'Cap' fit option on the simple patch meshes and the 'natural' fit option on the cylinders for the best effect! NB: Remember if resizing you must re-size each patch individually to avoid deforming the other patches. An alternative would be to merge your 4 simple patch meshes together using Plugins------>Bobtoolz------>Merge Patches. It'll only let you merge 2 at once though, so you'll have to merge 2 quarters together on each side, and then merge the 2 newly created halves together afterward for one single , convenient patch.
  4. Tutorial originall by Immenor Title: Hand Shaped Terrain Subject: How to create your own terrain by hand. Written by: Immenor Tutorial written for: GTK Radiant 1.4.0 Similar concept work like in: N/A Difficulty level: 6/10 Expected time to complete for first attempt: 35 mins Prerequisites: Basic familiarity with mapping and GTK Radiant Hand Shaping terrain is creating brushes that seamlessly fit together, so that when a rock or grass texture with *phong shading is applied to the brushes, it appears as sloping hills or steep rock walls in-game. Video Walkthrough Downloads: VIDEO #1 VIDEO #2 VIDEO #3 VIDEO #4 Introduction First we will cover the concept of how terrain in video games is made. Terrain is made up of either: 1. Trisoups 2. Quadsoups A trisoup is a collection of triangles, which create the terrain and a quadsoup is a selection of squares that make up the terrain. Figure 1 is a picture of a Trisoup in radaint. Figure 2 is a picture of a quadsoup in radiant. When I am making terrain, I use a combination of both trisoups and quadsoups. I mix and match them to get the proper shape of terrain I desire, as well as to position the blending of textures. For now however, It is important that you learn how to create terrain with both methods. Tri-Soups There are 2 main ways I create basic Trisoups. The first way, is to make a square brush and cut it in two with the cutter tool. This is shown in figure 3. You will now have 2 triangles that together form a square. Duplicate this pair of triangles, 3 times and position them so that they look like in figure 4. Now you have a collection of 8 triangles that form a square, as well as a diamond shape (or tilted square) in the middle. Select all 8 triangles and copy them 4 times so that you have 3 more collections of the 8 triangles, lined up against your first collection, like in figure 5. Select a group of 8 triangles and press V. Vertexes will appear on the triangles. This is how you are going to shape your terrain. The vertexes on the top of your terrain are the ones you will be manipulating. Figure 6 is a picture of 8 triangles selected, with there vertexes showing. Now drag the vertex''s on the top of the triangles to adjust the height of each triangle that makes up your terrain. Remember that Terrain is made out of many triangles, and also remember that each vertex of one triangle must touch another. If it doesn't then the triangles don't fit seamlessly together, the terrain in-game will not appear smooth. Figure 7 is a example of 8 triangles that I have changed the vertices of. I made one edge stick higher up, and one edge go farther down. I have also applied the grass texture to it so it is easier to see. Do this same process for the other 8 triangles, make sure that all the triangles fit seamlessly together, so that in the end, you have a continuous surface. Figure 8, is a example of all the triangles when I finished shaping them. Figure 9 is the same triangles, but with there vertexes showing. You have now created a small patch of ground terrain. Congratulations. Now onto Quadsouped Terrain. Quad-soups Quadsoup] basicaly can be created in the same way Trisoups are, except instead of 2 triangles to make up a square, its just one square. When making a Quadsoup and adjusting its vertices you do not want the squares in it to have splits down the middle. You want them to be flat. Figure 10 shows 4 squares in a basic trisoup properly done. Figure 11 Shows four squares in a trisoup done the way you don't want. As you can see in figure 11, some of the vertex'' have been dragged down farther creating lines on the squares. If you want to get the same shape that this gives you, that's where you use tri-souping. If your going to be shaping with squares, keep with flat tops. Shaping with quad-soups seems to almost shape itself as you build. if you want one edge lower down you must drag others upwards to keep the top plane straight. In this way, quad-soups can begin to form themselves. If you require more precision, then that is where tri-soups come into place. Quad-soup Templates The next thing you must learn about quad souping is making templates. A template is a set of brushes that yo u will duplicate and modify. First you must make a template. Figure 12 is a example of a completed template. To make a template, first create 1 square on the top view grid (z). Then go onto a size view, and place your cursor on the side of the brush, hold down ctrl, and drag downwards. This is shown in figure 13, and 14. Copy this square, and move it over so it is right next to the last square. Then use the ctrl drag so that the two squares sides fit together, then drag the other side to where you want it to be. Repeat this, until your template is finished. Now select your whole template, and duplicate it. Move it over so it is next to its original self, like in Figure 15. Navigate in the 3d view so that your camera can see the side of your copied template that is not touching anything (figure 16). Position your mouse on one of the brushes in the 3d view, and once again click and drag downwards. The end result will be like in figure 17. Now, continue doing this dragging your template up and down with the ctrl drag feature. Also, try dragging it left and right, by positioning yourself in the 3d view looking down at the template from above. Clicking on the side of the template and dragging with ctrl left or right (figure 1.) Fiddle around with this, and copy your template enough to make a small amount of terrain like in figure 19. Figure 20 is the same patch of quad-souped terrain with all the brushes selected. Proper use of Tri-souping and quad-souping When I am creating a terrain, this is how I use quad-souping and tri-souping. I use them together. I start with a template, and then build off it with tri-souping when I need more accuracy in the shape of the terrain. Remember these things when building your terrain: Quad-souping is good for Dotproduct2 blending, because you have more control over where your blends are. Quad-souping is good for creating terrain you need less control over, because it tends to shape itself, and often makes more realistic differences between how fast a hill or land form will rise up or down. Tri-soups are good for creating terrains with exacting accuracy. You have more control over the shape they will create then quad-soups. Combine your quad-soups and tri-soup techniques so that all your brushes fit together the way you want. Your not restricted to one or the other, be creative, and use the ideas to form your own ways

    Horizon Blending

    Title: Horizon Blending Subject: How to create a seamless horizon blend between your 3D terrain and a 2D Skybox. Written by: Szico VII Tutorial written for: JK3 Similar concept work like in: N/A Difficulty level: 10/10 Expected time to complete for first attempt: 2-4 hours Prerequisites: Understanding of trisoup and quadsoup terrain creation, Understanding of Alpha-Fading, Proficiency in Radiant 1.4.0 and in shader creation and useage, an image editing program that can blend 2 textures together, understanding of func_groups and how to use them. Introduction:Creating the Skybox This tutorial will instruct you on how to create a seamless blend between your 3D terrain and playable map and the horizon of your skybox, which I call "Horizon Blending". It will involve editing of the skybox image files, so you will need an image editing program capable of blending two textures together. I this tutorial I use Photoshop CS3, however you are free to use any program which performs a similar function. There is a fair amount of assumed knowledge you will need to follow this tutorial, most importantly the basics behind quadsouped and trisouped terrain, and you must be able to create your own .SHADER files and be able to get them working in Radiant. This tutorial also assumes strong knowledge of the editor and its various shortcut keys, although these will sometimes be listed for your convenience. Additionally, this method makes use of the alpha-fade system, so background knowledge on this system will help when customising different terrain blends. However, shaders and information will be provided in this tutorial which you can simply copy and paste, so it is not necessary to grasp the full concept provided you follow the instructions carefully. Below is a list of tutorials you may find useful to read prior to attempting a terrain/skybox blend. Hand-Shaped Terrain Updating your Compiler Terrain Blending IMPORTANT! You must have Q3map2 version 2.5.16 installed for the alpha-fade system to work. Download it here (should be installed with GTKRadiant too) and use the above tutorial to install it if necessary. Opaque Horizon Blending (no Water) EXAMPLE FILES! - You should download the example files and extract them all to your base folder whilst reading through this tutorial, as they will help you to understand how things work! The large file size is due to the high-res textures. Download example/source files The first thing You will need to create is the terrain in which your players can move around in. This is basically your normal level, so build whatever you want. However, it is important that you decide on a texture which you want to use to blend into your horizon. In this tutorial, I shall be making a desert themed map, so the edges of my playable area will be using a sand texture. Ideally this texture should be large and scalable, as it will be stretching a long way into the distance and the less repetitive it looks, the better. There are a few design tips I have however, that will make your skybox blend look better. If possible, have your playable area raised (i.e on a small hill) this is because it means the player is ABOVE the horizon line in relation to the skybox, and this allows you to keep more of your skybox visible (more on this later) If you are trying to create an ocean effect that a player can swim in, don't raise it too much as this will cause problems. Try and make your map in a mainly circular shape - i.e, If you stuck a giant circular brush underneath it, it would fit onto it with no sections jutting out. Make sure that when you have finished creating your level, the edges of the terrain of it are squared off and the same texture is all around the border. You should also place clip brushes to prevent players running out into the horizon! Here is the sand texture I have chosen to use for my terrain blend: NB: You do not need to download this texture as it is included in the example files! And here, is my basic terrain. (squared off at the edges) It doesn't have any detail in it, as this is only for demonstration purposes, but you can build whatever you want in this area as you would in a normal map. Feel free to make the terrain undulate (but keep the outside edges all the same height and using the same chosen texture) or do other alpha blends within this section Now we can begin working on our skybox horizon blending itself. The first thing You will need to do is find an appropriate skybox, but bear in mind you will be losing any detail below the halfway line in them, so choose appropriately. Sometimes skyboxes that might not seem to be good choices for a seamless blend turn out to be quite good. I've chosen to use a base JA skybox, DESERT. You will need to place all your skybox images in a custom texture folder. For the purposes of this tutorial, I have chosen the folder textures/szico_desert. One of my skybox images can be seen below. "textures/szico_desert/desert_ft.jpg" You will also need to setup a sky shader for your new skybox. I have pasted one you can use below. textures/szico_desert/sky { qer_editorimage textures/skies/sky.jpg q3map_sun 1 1 1 350 180 45 surfaceparm sky surfaceparm noimpact surfaceparm nomarks notc q3map_nolightmap skyParms textures/szico_desert/desert 512 - } NB: This sky shader has "Sky Lighting" which means a global sun will illuminate the level. You can choose to remove this if you wish, by deleting the line: "q3map_sun 1 1 1 350 180 45" Open up your image editing program of choice! Before we continue, I should explain the main principle behind this skybox blending. Theory The main idea behind blending 3D terrain into a skybox is quite simple. In order for both the skybox and your terrain to both appear to have blended together, they must both be the same colour and shade where they "meet." (In reality, they never meet as the skybox is drawn at an infinite distance from the player, but to the player"s eyes ingame, this is how it will appear.) This blend occurs at the horizon line on your skybox, that is, exactly halfway up your side-facing skybox textures, provided the player is on a flat plane. So here is what happens: You blend your side-facing skybox images (skybox_rt, skybox_bk, skybox_lf, skybox_ft) to a solid colour of your choice halfway down. The colour you choose should be close to the shade of the skybox pixels directly above where the blend occurs, and a similar shade to your texture that you picked earlier on (in this case, a yellowy sand texture) Your bottom skybox image should be converted into a single colour that matches the one you picked for the sideways images. Do not edit your UP skybox image. You then create a flat section terrain which stretches out into the distance in your map, and gradually blend this texture to the same shade of colour that you used in your skybox, using alpha-fade brushes. This gives the impression of a seamless blend, as shown below. An important thing to note is that the lower down a player can move within the playable area of the map, the "horizon" line moves further up the side of your skybox texture. You will have to experiment to find the best place to blend your skybox images. So, the next section of the tutorial will quickly explain how to create your skybox images using Photoshop. NB: - The next few steps show how to blend your side images using Photoshop - If you use a different program you will need to find an equivalent tutorial for this section. PHOTOSHOP ONLY Step #1 - Open up your skybox_dn.jpg image. Recolour it to a completely flat shade (Remember, the shade should be approximately equal to the colour of your terrain texture) Some of JKA"s default skyboxes already have the bottom skybox image as a flat shade, so you do not need to edit these. An example is shown below, using the Korriban skybox. SAVE THIS IMAGE! Step #2 - Create a smaller 64x64pixel texture and colour it completely the same shade again. (This is the image we will later use to blend our terrain texture with.) SAVE IT as textures/szico_desert/yellowblend.jpg (Feel free to change the name when creating your own skybox blend that doesn"t use yellow as its colour) Step #3 - Open your 4 side-facing skybox images (skybox_rt, skybox_bk, skybox_lf, skybox_ft.) You can start with any one of these 4. Step #4 - Create a new layer (Layer --> New --> Layer...) Step #5 - Use the fill tool to make this layer the same colour as the DN skybox image. Step #6 - Create a new Layer Mask (Layer --> Layer Mask --> Reveal All...) A white box should appear next to your layer thumbnail in your layers window. Step #7 - Select the Gradient Tool, and make sure that you are using the white/black flat gradient, as shown below: Step #8 - Press and Hold SHIFT, whilst clicking and dragging your mouse upward. The further you drag your mouse upwards, the more gradual the blend. You can try again by repeating this action if you make your blend in the wrong place. Ideally your blend should start just about the halfway point, and extend slightly above it, although this might change depending on your specific map horizon level. This will create an effect as shown below: SAVE THIS IMAGE over your original image. Step #8 - Now we need to paste this new layer mask into the other 3 side-facing skybox images. In your layers window, RIGHT-CLICK on the layer that is named "Background," and press DELETE. This should leave you with your yellow blending only. Step #9 - Copy everything left over. First hit Ctrl+A to select everything in your image, and then go Edit --> Copy Merged. This will add your yellow/transparent blend to your clipboard. Step #10 - Paste this layer over your remaining 3 side-facing skybox images, so all of them blend to a solid yellow colour at the same level, as shown below. SAVE ALL OF THEM OVER THE ORIGINAL IMAGES! You have now finished all the editing of your skybox textures! The next section will deal with blending your terrain into this skybox. Blending your terrain: Opaque Horizon Blend First up, here is a basic explanation of what an alpha fade is, and how it works. An Alpha-fade brush is simply a brush you make in Radiant which is covered with an alpha-fade shader. Alpha fade shaders are used by a mapper to blend textures together in varying degrees. In this tutorial, we will only be blending 2 textures together, similar to the way easygen blends textures together, but using a different method. For this tutorial, our PRIMARY texture is my sand texture (textures/szico_desert/sand.jpg), and my SECONDARY texture is my yellow texture (textures/szico_desert/yellowblend.jpg) Wherever an alpha 100% brush covers a brush vertex with a special blending shader applied, it will tell the shader to show the Primary texture at 100% opacity. Wherever an alpha 0% brush is applied, it will tell the shader to show the primary texture at 0% opacity, and thus the secondary texture will be fully visible. Values of 50% and other inbetween show the primary texture at various opacities, thus creating a blended effect. Shaders: You will need to edit all these shaders into your own shader file for your own maps - however, all the tutorial images/shaders can be found in the included example files. PHONG SHADER: - This is the shader that should be applied to all the edge brushes of your playable area. It is a phong shader, which means it smooths shadowing over trisouped and quadsouped terrain, preventing hard edges or splodge shadowing/lighting from occuring. This shader is NOT affected by alpha fade brushes. textures/szico_desert/sand { qer_editorimage textures/szico_desert/sand q3map_material Sand q3map_shadeangle 90 q3map_nonplanar { map $lightmap rgbGen identity } { map textures/szico_desert/sand detail blendFunc filter } } SAND/YELLOW BLENDING SHADER: - This is the shader which is applied to all the flat brushes outside your playing area, and these are the brushes where the blending takes place. This shader is affected by any alpha fade brushes which touch the vertices of the brush it is applied to. It also has an editorimage so you can tell the difference between the normal phong sand shader and the blending shader in radiant. textures/szico_desert/sandyellow_blend { qer_editorimage textures/szico_desert/sandyellow_blend q3map_material Sand q3map_shadeangle 90 { map $lightmap rgbGen identity } { map textures/szico_desert/sand blendFunc GL_DST_COLOR GL_ZERO } { map textures/szico_desert/yellowblend blendFunc blend alphaGen oneMinusVertex } } ALPHA FADE SHADERS: - These are the shaders that give the alphamod brushes their paramaters and cause them to affect your blending shaders. They are editor only and are used only during the compile process, and do not appear ingame. textures/szico_desert/alpha_000 { q3map_alphaMod volume q3map_alphaMod set 0 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } textures/szico_desert/alpha_010 { q3map_alphaMod volume q3map_alphaMod set 0.1 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } textures/szico_desert/alpha_020 { q3map_alphaMod volume q3map_alphaMod set 0.2 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } textures/szico_desert/alpha_030 { q3map_alphaMod volume q3map_alphaMod set 0.3 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } textures/szico_desert/alpha_050 { q3map_alphaMod volume q3map_alphaMod set 0.5 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } textures/szico_desert/alpha_075 { q3map_alphaMod volume q3map_alphaMod set 0.75 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } textures/szico_desert/alpha_100 { q3map_alphaMod volume q3map_alphaMod set 1.0 q3map_nolightmap surfaceparm nodraw surfaceparm nonsolid surfaceparm trans qer_trans 0.75 } The basic layout for our overall terrain will be as shown below. It is important to note that all your skybox terrain blending brushes (Green in the image below) should be FLAT. Key: GREEN - Flat brushes covered with the SAND/YELLOW BLENDING shader. Each different shade of green is a different set of brushes. ALPHA XX% - Brushes which overlap the edges of the flat GREEN brushes either side and use the alpha fade shaders. SKYBOX - Your skybox shader applied to a large box which extends around your terrain. PLAYABLE 3D - The area where your map itself is located, bordered by the PHONG SHADER. Here is the same setup shown in Radiant. The playable area of your map which you made earlier is in the center. Here's how you go about creating this shape, starting from your basic playable area (remember it should be a square shape and the edges should use the phong shader described above) Remember the basic terrain we made earlier? Well, it's time to add to this. We will start with our first "layer" of terrain blending brushes and form them into a hexagonal shape around our central box. Create a hexagonal shape around your central area using 6 brushes as shown below. Texture them all with the SAND/YELLOW BLENDING shader. You will notice the brushes in my central area all use the PHONG shader, but in your map this is not necessary - only the brushes nearest the outside of this area need the phong shader. If you wanted grass in the middle, you could then blend the phong shader to grass, but that's something for you to try in your own time. If you're fine with sand all the way, then leave it as I have. Now it's time to add the alpha-fade brushes. Place 4 alpha fade brushes (mitred) along the seams between your 6 new terrain blending brushes, and any brushes making up the edges of your playable area, as shown below. The Alpha Fade 100% brushes used will tell the game to show 100% of the primary texture (The sand) where the terrain blending brushes meet the normal phong shader. As the primary texture and the phong shader are the same, they should match up. The alpha fade brushes should extend above and below the terrain brushes, AND they should extend a short way into the brush on either side, to make sure they are over the brush vertexes. I have also added CLIP brushes to prevent players from leaving the main map and venturing into our skybox/terrain blending section. Now we need to make the next layer of brushes. In case you don't understand why we are making it in layers, it is because alpha fade brushes only work when they are placed over brush vertices, and so if we just made one big brush, it wouldn't have any effect, except for at the edges. However, this time we will be using an alpha fade 70% brush on the seams - this means our secondary texture (the yellow texture) will start to show up. It wont show up in radiant but after you have compiled you will see it. NB: I have hidden the clip brushes for ease of viewing You now just need to add the remaining layers until you get to the final layer and can use the 0% Alpha Fade brush. You can use the above images as reference if you wish. NOTES: You are free to make these layers wider or shorter, or use more of them with more specific alpha fade brushes. I have only used 100,75,50,20 and 0%, but you can use any value between 1-100% by editing the alpha fade shaders to suit your needs. Increasing the width of the layer results in a more smooth transition, for long terrains stretching out into the distance. Smaller widths tend to fall off faster, but do save space in your map, so aim to make them as thin as possible whilst still maintaining a good looking blend. For maps where you can move to very high points, say towers and the like, you will probably need wider brushes to made the blend look good. When you are finished, your map should resemble my sample map. Don't forget to add your skybox box if you haven't already! Compile and check it out ingame!! A water skyline: Non-Opaque Horizon Blends This next section builds on the last by showing you how to create non-opaque terrain blends - that is, using water as well as fading terrain to create your horizon. It will also show you how to add a surf to circular islands using alpha fading, and how to add caustics to shallow water, again using alpha fading. The first thing to note about blending water is that the terrain setup is slightly but significantly different from when you make an opaque terrain blend. With the opqaue blend shown in the above section, you only need two sections of terrain: The central playable area, and a flat plane for your blending terrain which stretches into the distance. However, with a non-opaque water blend, you have to remember that you will be able to see through the water, so there needs to be another layer of terrain beneath it. Additionally, your underwater sand layer is not going to be completely flat, as shores generally tend to slope off into the water, and would look silly if they just went down and then was straight. The second point is that your water layer will need to blend to transparency, rather than a solid colour texture, which will require a different shader! The image below shows the differences between the two types of horizon blending. And finally, your water will start (on the shore) as transparent, then quickly fade to 100% water shader, and then gradually back to transparent. This it to prevent a hard line occuring where the water meets the shore. At the end of this section will be an optional paragraph or two about adding underwater caustics and a surf should you wish. On the left: Non-Opaque blending, and On the Right, Opaque blending. Shaders: You will need to edit all these shaders into your own shader file for your own maps - however, all the tutorial images/shaders can be found in the included example files. PHONG SHADER: - This is the shader that should be applied to any brushes exclusively above your water level, i.e, only brushes that have no section of them underneath the water line! It is a phong shader, which means it smooths shadowing over trisouped and quadsouped terrain, preventing hard edges or splodge shadowing/lighting from occuring. This shader is NOT affected by alpha fade brushes. textures/szico_beach/sand { qer_editorimage textures/szico_beach/sand q3map_material Sand q3map_shadeangle 90 q3map_nonplanar { map $lightmap rgbGen identity } { map textures/szico_beach/sand detail blendFunc filter } ] SAND/BLUE BLENDING SHADER: - This is the shader which is applied to all the underwater terrain brushes (including those that are partly underwater and partly above water), and these are one set of brushes where blending takes place. This shader is affected by any alpha fade brushes which touch the vertices of the brush it is applied to. It also has an editorimage so you can tell the difference between the normal phong sand shader and the blending shader in radiant. It will be applied to a trisoup/quadsoup. textures/szico_beach/sandblue_blend { qer_editorimage textures/szico_beach/sandblue_blend q3map_material Sand q3map_shadeangle 90 q3map_nonplanar { map $lightmap rgbGen identity } { map textures/szico_beach/sand blendFunc filter detail rgbGen identity } { map textures/szico_beach/blueblend blendFunc blend rgbGen identityLighting alphaGen oneMinusVertex } } OCEAN BLENDING SHADER: - This is the shader which is applied to flat ocean brushes (i.e, your water level.) and these are one set of brushes where blending takes place. This shader is affected by any alpha fade brushes which touch the vertices of the brush it is applied to. It does not have a lightmap so you will need to adjust the brightness/contrast/colours of the textures manually if you want to use it for a night-time water. It contains multiple layers, all of which will fade to transparency when the right alpha fade brushes are applied to it, and the extra layers will simulate various refractions off the water, as envmaps don't work with this kind of blending (or, I haven't got them to work properly yet. textures/szico_beach/oceanwater { qer_editorimage textures/szico_beach/water q3map_nolightmap qer_trans 0.65 q3map_material Water surfaceparm nonsolid surfaceparm trans surfaceparm water cull none sort additive { map textures/szico_beach/water blendFunc GL_SRC_ALPHA GL_ONE rgbGen identity alphaGen vertex tcMod scroll 0.01 0.025 } { map textures/szico_beach/oceanwater blendFunc GL_SRC_ALPHA GL_ONE rgbGen identity alphaGen vertex tcMod scale 0.25 0.25 tcMod scroll -0.0075 -0.03 rgbGen identity } { map textures/szico_beach/oceanglow blendFunc GL_SRC_ALPHA GL_ONE rgbGen identity alphaGen vertex tcMod scroll -0.0075 -0.03 rgbGen wave sin 1 0.05 0 0.5 tcMod scale 0.5 0.5 rgbGen identity glow } { map textures/szico_beach/oceanglow2 blendFunc GL_SRC_ALPHA GL_ONE rgbGen identity alphaGen vertex tcMod scale 0.35 0.35 rgbGen wave sin 1 0.05 0 0.5 tcMod scroll -0.05 0.008 tcMod rotate 4 rgbGen identity glow } { map textures/szico_beach/oceanglow3 blendFunc GL_SRC_ALPHA GL_ONE rgbGen identity alphaGen vertex tcMod scale 0.15 0.15 tcMod scroll -0.005 0.01 rgbGen wave sin 1 0.05 0 0.5 rgbGen identity glow } } Setting up your Terrain Firstly you will need to repeat the steps shown previously to create your skybox. As this is now a water-themed skybox, blue is a more appropriate colour to blend to, instead of yellow, so blend to a blue colour instead (and save a 64x64 pixel texture using the same block colour). My skybox is shown below. Next up, you'll need to create your playable terrain. For my example map, the player is on a beach, and so can actually enter the water. For this reason, my underwater terrain is entirely trisouped. Remember, any brushes exclusively above water should be your phong shader, at least around the edges, but within that you can build your normal map and anything you want. Any brushes which touch beneath your planned water line in any way should be covered with your sand/blue terrain blending shader, as shown below. Remember your central area must (obviously) be higher in the middle and gradually slope outwards, although the exact incline and shape is entirely up to you. The next part is adding your alpha fade brushes to this terrain to cause it to gradually blend to the same blue colour that you have used for your skybox. Because we are using our terrain blending shader on a trisoup this time, we will need a LOT more alpha fade brushes, as you will need an alpha fade brush for each vertex of your trisoup. It is is a little difficult to explain, so you should look at the source files as you read through, but you need to move in a circular motion around the far outside of your trisoup, placing Alpha 0% 'poles' on every set of brush vertexes. Once you have finished the outside layer of vertexes, you should do the next layer using Alpha 20/30% brushes. Depensing on the size of your terrain, you can control how gradually the blend occurs by using a greater variety of alpha fade brushes. For my map, I used 0,10,20,50 and 100%. The basic layout is shown below. Select all your brushes with your Sand / Blue Terrain Blending shader AND the alpha fade brushes you have added (but not your phong shader brushes) and FUNC GROUP THEM! You can hold Alt+Ctrl and click one of these brushes to quickly select the entire group if you wish in the future. This is what you have done so far looks ingame. The blend might seem very sharp and not very smooth at the moments, but when we add the water brush above it it won't be noticeable. Obviously, bigger islands will need a large area of underwater terrain and a more gradual blend. FUNC_GROUPS The type of blending used within this section of the tutorial relies on the use of func_groups within radiant. Func_groups are used to group brushes together within the editor, both for convenience, and in this case, to determine which alpha fade brushes affect which sections of terrain Alpha fade brushes will only affect terrain blend shaders on other brushes within the same func_group. This is particularly necessary in this section because there will be overlapping areas of terrain, but which need to be affected by different alpha fade transparencies. Each different set of brushes with a blending shader will be part of a different func group. To make a set of brushes into a func group, simply select all the brushes you want to include in the group, go Right Click --> func --> func_group To select all the brushes within a func group, hold Alt+Ctrl and click any brush that is part of the group you wish to select. Adding the water: The setup for your water brushes are remarkable similar to the setup used in the first section of this tutorial for an opaque terrain blend. The water brushes must be flat as before, and will still be in a hexagonal shape with alpha fade brushes applied to the vertex seams. There are however, 3 crucial differences here. NOTE #1 - Aside from the top facing face of your brushes, all the other sides should be caulk_water. NOTE #2 - You must FUNC GROUP all your alpha brushes and water brushes together to make sure the alpha fade brushes used here don't affect the underwater terrain you just made and mess the blending up. NOTE #3 - You should use alpha 0% shaders for moth the outermost brushes and the innermost brushes, to both blend the water to transparency at the edges of the map, and right on the shoreline to prevent a hard edge from occuring where it means the sand terrain. The 2nd innermost layer should go straight to a 100% alpha brush, and then gradually fade out towards the outermost layer. An example is shown below. The water brushes, with the rest of the terrain hidden: The map with both the water terrain func_group AND the sand terrain func_group visible. And the map ingame: And that's it for creating your water! If you want to learn how to add underwater caustics and a surf, carry on reading! Light Refractions Underwater: Underwater Caustics Adding underwater caustics is quite simple. You will need a shader similar to the one shown here: CAUSTICS SHADER: - This is a DECAL shader. This means that it if placed on a brush that occupies the same plane as another brush, this shader will always be shown on top. We can use this to good effect by duplicating the orginal sand/blue terrain blending brushes and simply applying this shader to them. Although identical shaped brushes will now be in place, the brushes with the caustics shader will be prioritised ingame. textures/szico_beach/caustics { qer_editorimage textures/szico_beach/caustics_editor q3map_material Sand q3map_shadeangle 90 q3map_nonplanar q3map_nolightmap surfaceparm trans surfaceparm nonsolid surfaceparm nonopaque qer_trans 0.5 polygonOffset { map textures/szico_beach/caustics tcmod Scale 4 4 blendFunc GL_SRC_ALPHA GL_ONE alphaGen oneMinusVertex rgbGen wave sin 1 0.05 0 0.5 tcMod scroll -0.0075 0.005 } { map textures/szico_beach/caustics2 tcmod Scale 4 4 blendFunc GL_SRC_ALPHA GL_ONE alphaGen oneMinusVertex rgbGen wave sin 1 0.15 0 0.8 tcMod scroll -0.0175 0.025 } { map textures/szico_beach/caustics3 tcmod Scale 4 4 alphaGen oneMinusVertex blendFunc GL_SRC_ALPHA GL_ONE tcMod scroll 0.15 0.15 rgbGen wave sin 1 0.15 0 0.8 glow } } Hide your water terrain brushes with the alpha fade brushes, and select your brushes covered with the Sand / Blue Terrain Blending Shader. Copy and Paste the entire set of brushes, and change the shader to your caustics shader. Re-func group these brushes to make them a seperate func group from the original set of brushes!You will now need to change the centre-most layer of alpha-fade brushes from 100% alpha to 0% alpha, as we need the caustics to blend to transparency as they touch the shoreline, then become more opaque as you go beneath the water, then fade to transparency again as you move away from the centre of the map. You may need to change some of the other alpha fade brushes to get a clear set of caustics visible ingame MAKE SURE YOUR CAUSTICS BRUSHES AND THEIR ALPHA-FADE BRUSHES ARE ALL FUNC_GROUPED AND IN A DIFFERENT FUNC_GROUP FROM YOUR ORIGINAL TERRAIN! In Radiant, you will see Z-fighting, as shown below, But ingame, it should look like this! - Alpha fading used to create underwater caustics!
  6. Title: Admin Password Creation (Atlantica) Subject: Creating a custom admin room password for Atlantica or other maps. Written by: Szico VII Tutorial written for: BehavED/JK3/Atlantica Similar concept work like in: N/A Difficulty level: 5/10 Expected time to complete for first attempt: 25 mins Prerequisites: Atlantica Source, BehavED and Pakscape programs downloaded. Before we get started with this tutorial, you will NEED two programs in order to get this to work, as well as the Atlantica Source Files NB: This was written specifically to edit the passworded system found in my map Atlantica, but it can be transposed and used in other maps. Firstly, you will need a program called BehavED, and secondly you will need a program called Pakscape. BehavED is a scripting tool used to create the password script and is part of the Jedi Academy SDK (Developer’s Kit), and Pakscape is used to make PK3 files. The download links are below: Pakscape Jedi Academy 1.01 patch (if using disc version) Jedi Academy SDK (Developer's Kit) To install the developer’s kit (SDK) you may use the following tutorial Look for the section named "Installing the developers kit." Once you have installed the SDK and Pakscape, and downloaded and extracted the Atlantica Source Files, we are ready to continue: Open BehavED – you should see a window that looks like this if you have installed it correctly You should now open the default password script file. On the right hand side of the program, find the File>Open button, and press it. Browse to the following folder:Jedi Academy/GameData/base/scripts/atlantica/keycode/ And open the file named universal.txt Your BehavED screen should now look like below: Click the small + sign next to the first ‘IF’ line, and then click the + sign under the ‘IF’ that appears under that. Repeat until you have pressed all the + signs that stem from the first IF line, as shown below. You will see that the current information (indicated by the green arrows here) reflects the default code used in the map. Changing this information is relatively easy. To change the code, simply replace the values shown above with your own values by double clicking each line and editing the value in the right-hand most field, as pictured below. Once you have replaced all 6 values, press SAVE. However, we still have another section to edit which relates to how the code resets itself to 999999 (ingame) after a successful use. Click the + Sign before the second ‘IF’ line to open another block of code, a longer one this time. We are only interested however, in the sections between the lines shown below. Basically, in order to reset the counter back to 9 after a successful password input, the script tells the counter to move down one number, as many times as it takes to return it to 9 from its ‘success’ position. For example, the first digit of your new code might be 4. This means, when a code is successfully inputted, the digit of button1_code_useable will be 4. (The next step down after 0 is back to 9) In order to return to 9, the script should tell the counter to move down by 1, five times, with the value decreasing from 4, to 3, to 2, to 1, to 0 and then back to 9. Each block of code between the ‘wait 100’ lines tells the digits to decrease by one for each console mentioned. FOR EXAMPLE, THE USING THE ORIGINAL INPUT - 557752 The first block of code decreases each digit of all 6 consoles by 1, thus making the digits show 446641. The second block of code is the same as the first, and also decreases each digit of all 6 consoles by 1, thus making the digits show 335530. The third block of code is identical to the first and second blocks, which tell the digit values of consoles 1-6 to decrease by 1, resulting in the digits 224429. (After a console digit reaches zero, the next digit down is back to 9) CONSOLE #6 HAS NOW RETURNED TO ITS 9 POSITION, AND SO IS NOT INCLUDED IN THE FOURTH BLOCK OF CODE, AS THAT WOULD THEN SET THE DIGIT VALUE OF THIS CONSOLE TO 8. As such, the fourth block of code only contains 5 lines, which tells the digit values of consoles 1-5 to decrease by 1, resulting in the digits 113319. The fifth block of code is identical to the fourth block, which tells the digit values of consoles 1-5 to decrease by 1, resulting in the digits 002209. The sixth block of code is identical to the fifth and fourth block, which tells the digit values of consoles 1-5 to decrease by 1, resulting in the digits 991199. CONSOLE #1,2,5 AND 6 HAVE NOW RETURNED TO THEIR ORIGINAL POSITIONS, AND SO ARE NOT INCLUDED IN THE SEVENTH BLOCK OF CODE, AS THAT WOULD SET THE DIGIT VALUES OF THESE CONSOLES BACK TO 9. As such, the seventh block of code only contains 2 lines, which tells the digit values of consoles 3 and 4 to decrease by 1, resulting in the digits 990099. The eighth block of code is identical to the seventh block, which tells the digit values of consoles 3 and 4 to decrease by 1, resulting in the digits 999999. CONSOLE #1,2,3,4,5 AND 6 HAVE NOW RETURNED TO THEIR ORIGINAL POSITIONS, AND SO WE HAVE REACHED THE END OF THIS PORTION OF THE SCRIPT. The tricky part about this section is figuring out how many times you need to ‘use’ each console within the script. You can copy/paste lines if you need to add more, or hit the delete key to remove lines. If you need to create new blocks, simply copy and paste an entire block( with the wait 100 line also.) Once you have finished your changes to the script and are happy they are correct, SAVE the script and press the button that says ‘COMPILE.’ This will generate a file called UNIVERSAL.IBI in your :Jedi Academy/GameData/base/scripts/atlantica/keycode directory THIS IS THE IMPORTANT FILE WE NEED FOR CREATING OUR PK3, SO DON’T DELETE IT. NEXT STEP – MAKING OUR PK3 FILE. OPEN UP PAKSCAPE.EXE Go to the File menu > New to create a new pk3 file, and then add folders (Object >New Directory) so that you have the setup shown below: scripts/atlantica/keycode/UNIVERSAL.IBI scripts/atlantica_rpg/keycode/UNIVERSAL.IBI Once you have created this directory setup, click and drag your UNIVERSAL.IBI file into both ‘keycode’ folders, the one in atlantica AND the one in atlantica_rpg. Click the ‘save’ icon, and make sure you SAVE YOUR FILE AS A PK3 (.PK3) and NOT a .zip It is important that the file name of this pk3 is alphabetically further down than the ‘Atlantica.pk3’ file or else the original script will still take priority over your new one. As such, you should name this file: z_AtlanticaCustomKeycode.pk3 You can now upload this file to your server (it is completely server-side, none of your clients will need it)

    Rotating Doors

    Originally written by lassev - Source Title: Rotating Doors with Areaportalling Subject: How to create realistic rotating doors which use areaportals. Written by: Lassev Tutorial written for: Jedi Academy/BehavED Similar concept work like in: N/A Difficulty level: 4/10 Expected time to complete for first attempt: 30 mins Prerequisites: Entity linking, Scripting, Basic Brush Manipulation, BehavED installed Introduction Rotating doors, like the ordinary swinging doors that we use all the time in the real world, are not directly supported by the Jedi Academy game engine in the form of func_doors. However, they are easy to build using another entity called func_static and some simple scripting. Now that scripting is also supported in MP, the demand for swinging doors is higher than ever before. The title calls this tutorial "Rotating Doors With Areaportaling." Areaportaling is an easy and good way to keep the FPS up in your map, so you should do that every time you use a door between two rooms otherwise sealed from each other (no windows or other holes between them). However, if your rooms are leaking into each other or you don't want to use areaportaling for some other reason, you can skip the parts required for areaportaling (I will mention those parts separately). Technical Note: This tutorial requires very basic Radiant mapping skills. It also requires that you know what an ICARUS script is and how to use BehavEd to make some simple scripts. If you don't know how to use ICARUS, or you haven't yet configured BehavEd, you need to do and learn that first. Check Kengo's cutscene scripting tutorials for some ideas. They are, however, meant for JK2 Jedi Outcast, but despite the fact that the paths need some adjustment to Jedi Academy folders, they should be pretty correct... Building the Door in Radiant Let's launch Radiant and start the tutorial. First you need some basic architecture to be able to test the swinging door. For this specific purpose you obviously need two rooms to be connected with each other. Either use some preexisting map of yours or build one from scratch according to the specifications that I will give below. All right! If you start from scratch, build one room big enough to run around in game. Texture it, then select the walls, floor and ceiling, and clone it all. Place the new room next to the original, leaving something like 48-64 units between the rooms (or as much as you want). Next we will make a small corridor between the rooms. Notice that I used thicker brushes for the walls facing the other room. This has a special meaning in avoiding nasty errors later when we will make the actual func_static door entities. 2D from above: Fig 1. The room layout. The doorway between the rooms. I have thrown in some random brush blocks to make the rooms just a little bit more interesting: Fig 2. The doorway. OK. Let's now draw the door itself. In this tutorial, I will make double doors, instead of a single swinging door. This is just to illustrate that double doors are just as simple to make as the single type. However, if you prefer a single swinger, it's easy enough just to skip making the counterpart, and stretch your door to cover the whole doorway. Also, you will see easily enough how to adapt the script for just one door. Since I''m a fan of door frames, I will start my doorway by making them. I'll start it by drawing a big brush, 16 units thick, to span the whole mouth of the corridor, like in Fig 3.1 below (16 is also the thickness of the thicker than normal wall here). Then I clipped the frames and textured them, like in Fig 3.2. The portion that will form the actual doors is also reduced to thickness of 8 units, and placed in the middle of the frames, as you can see. Even if we are making double doors, don''t yet clip the door portion, if you are going to use one of the existing Raven double door textures (or one of your own equivalents). Texture it first, by fitting the texture 1x1. After that, you can easily just clip it in two in the middle, and you will have perfectly textured double doors! Just check Fig 3.3. Don''t forget to texture also the surface of the doors facing each other, and the surface facing the door frames. You don''t want to leave caulk there, because then they would be transparent, when the doors are open in game! Fig 3.1 Fig 3.2 Fig 3.3 Next you will need to place Origin brushes for both doors. The Origin brushes will be integral parts of the func_statics, but they won't show in game. However, they will define the actual point around which the doors will rotate. So they are indeed very essential for the swinging doors to work. In practice the Origin brushes are nothing but brushes covered with the Origin shader (texture). You will find the Origin shader in System. It has (in addition to the text "ORIGIN") an ugly orange color, so you should have no trouble finding it... Having the Origin shader selected, make a 16x16 piece, and place it exactly like you see in Fig 4. This means at about the half the height of the door, so that the middle of the Origin brush is 4 units (one grid button 3 square) over the hinge end of the door. This means the door will turn nicely in game, and won't invade the door frame. So, on the Y axis, the origin is three quarters inside the door, one quarter inside the frame. After you are done with the first Origin, do the exact same thing with the other half of the double doors. Fig 4. The Origin brush is selected to make it easier for you to spot it. Notice that it's not entirely inside the door, but also partially inside the frame. Actually, the size of the Origin brush does not matter at all, just its exact center coordinates. Finally we are ready to actually turn the doors into entities! Now, you need to select the origin brush, then the door half. You need to make two func_statics for double doors; the halves are totally separate entities; they will just be controlled at once. So, after you have selected the left origin and left door, right click, select func/func_static. Do the same trick for the right door. Now, select the left portion (the upper one in XY 2D) and press "N" to bring up entity properties. You will need to enter two keys over there (see Fig 5): key: script_targetname value: rotadoor1 key: soundset value: stone_door Fig 5. Entity properties for the left (upper in XY 2D) door. Script_targetname will define the name you will use in the affect command in the script controlling the doors. If you want to use some other name for your doors, feel free to do it! Soundset of course just gives some audible character to the doors. Name the other door likewise, only use "rotadoor2" as the script_targetname. You can also check the crusher flag of the door if you want it to cause damage to the player, if blocked. This is something you must decide based on your specific needs. The swinging doors should work properly, whether you make them crusher or not. Now we have only a couple of compulsory things to do, before we will leave Radiant for a while to write the script. We will also do some extra work to make the areaportal work, but if you don't want to do that, I will point out what you can skip. However, you will need to do the next things no matter what for the doors to work. Go to System textures again and fetch the Trigger texture. Draw a big brush that spans from one side of the door all the way through it to the other side, just like you can see in Fig 6. Turn it into trigger_multiple. Give it the following key: key: wait value: 10 Fig 6. The trigger_multiple to control the opening of the doors. This makes sure that the double doors won't be triggered to open a second time before they have had time to open, wait a little, and then close again. The actual script will determine how fast the doors open, how long they stay open, and how fast they again close. The combined time of those events will be made to be little less than 10 seconds. If you haven't saved your map before this, it's time to do it. Select some sensible name, but if you want to follow the tutorial without changing a single bit, you will have to name it "rotamap". However, it's easy enough to use what name you ever want. You will just need to create a folder named after you map under scripts. Next place a target_scriptrunner next to the trigger_multiple. Target the trigger to the scriptrunner. Then select just the scriptrunner, and bring up the entity properties. You will need to add the following keys and values: key: count value: -1 key: usescript value: rotamap/dooropener "Count -1" means that the script can be run as many times as needed (indefinitely). "Usescript rotamap/dooropener" is the key and value pointing to the script file we haven't yet made. If you named your map something other than rotamap, then just replace the map name with your own. Now we are finished with the compulsory things to be done in Radiant. If you are not interested in Areaportaling, just skip the things I will explain next, and jump to the scripting part. However, if you want to build a clean map, you can follow through the next steps. Areaportaling The Swinging Door Areaportaling a normal func_door couldn't be easier: You just place an areaportal brush there. Unfortunately it's not so simple with a rotating door. To work, an areaportal needs the origin of the entity to move. This is the triggering event that will adjust the areaportal. That is, the movement of the entity tells the game engine that it needs to remove the areaportal so that the player can see through the doorway. However, a rotating door won't move its origin at all; it will just rotate around it. How can we then use an areaportal at all with a swinging door? We will do it by tricking the game into thinking there is actually a door opening and closing just normally. And so there will be - but it will be an invisible, silent and a very fast bogus door. However, it's enough to make the game adjust areaportaling. All right, without further ado we will proceed to place an areaportal inside the double doors. You need only one areaportal, even if you have two doors, like in double doors. So, go to System textures and look for a "Skip" texture (it''s tiny and blue, just before the texture where Kyle is slipping, if you don''t seem to find it). Hit now "shift+ctrl+T" to filter away the big trigger so that you will be able to better work with the door. Select and then deselect once either of the doors - that will give you the right height for the areaportal. Then draw with the skip texture such a brush as you can see in Fig 7 below. Notice that the other side of the brush is in line with the walls and door frames of the room. This is necessary. The other side, however, is exactly in the center of the double doors. Otherwise the areaportal spans the whole doorway (excluding the frames made of structural brushes). After you are finished with drawing the brush, you will need to move it temporarily away from the right place. Drag it away from inside the door so that you can see the side that will be inside the door. Now, select just that surface, and texture it with the yellow Areaportal shader (also in System). See Fig 8 how it should look like, before you place it back to its proper place halfway inside the door (Fig 7). Fig 7. The placement of the Areaportal brush so that it will be in line with the walls of the room, and halfway inside the door entity. The areaportal texture (see Fig is located to the right side, in the middle of the door. Fig 8. The Skip/Areaportal textured Areaportal brush in a temporary location. Alright, we are about halfway through areaportaling now. Let's move forward. We must create the secondary, invisible door that will control the areaportaling. The secondary door will be made toggleable, and it''s controlled in the script controlling the door rotation. Without this secondary door the opening swinging doors will produce a very ugly HOM (House Of Mirrors). Drawing the bogus door is easy: Just clone your existing areaportal brush, click caulk to make it all caulked, and then resize as shown in Fig 9. Fig 9. The thickness of the bogus door is half that of the actual swinging doors. Turn the new brush into a func_door and give it the following entity properties: Fig 10. Entity properties for the toggle mode bogus door. Finally! Now the map is ready even with the troublesome Areaportal adjusting! If you are making an SP map, place the info_playerstart in some sensible place, but put it far away from the door so that it won''t be inside the trigger! Otherwise if you are making an MP map, place there the appropriate starting positions. Writing The Door Control Script You need to launch BehavEd to create the script controlling the doors. I'm not going to tell here how to script but what to script. As noted in the Technical Notes, you need to know something about scripting to survive the next part. All right, that being said, let's move forward. It's usually good to keep the Radiant and the map still at hand, because you might forget some targetnames. Type some notes in the rem(comment) if you want, then proceed to add your first command. Affect ("rotadoor1", /*AFFECT_TYPE*/ FLUSH ) { This will direct the following commands to the upper door. The doors will function basically mirror like when compared to each other. They will also be affected separately, but in effect everything will happen at once in game. That is, the doors will open simultaneously. OK, let's go forward. I will give you in Fig 11 all the opening script commands needed for "rotadoor1" and "rotadoor2", and explain what everything does in the script. Fig 11. The opening portion of the script. I have encircled with purple the command you need ONLY if you are going forward with the areaportaling. If you chose not to areaportal, don't insert the line encircled with purple, just insert the other rows. OK, use("bogusdoor") tells the game that it needs to open the fast, silent and invisible bogus door inside the actual swinging doors. This will make the game open the areaportal, allowing the player to see through the doorway. As you can see, the use command lies only once in the opening portion of the script. This is necessary, because the bogus door is a totally separate entity from the swinging doors, and using it twice would make it close immediately again, and we cannot do that yet. The command could as well reside inside the rotadoor2 affect group. The rotate (0 -90 0 , 2500) command means that the brush entity (the door) is going to be rotated ninety degrees toward the room on the left. Here you need to only think about the angle buttons in Radiant entity properties. -90 degrees is essentially the same as 270 degrees. Check my little picture below for some insight into rotating objects with the rotate command: Fig 12. Rotating entities with the rotate command. Imagine the squares as flags swinging around the axes. The most important thing to keep in mind while rotating is that the rotation is not relative to the current position (facing) of the brush. The rotate command will rather give every time a new absolute angle value for the object, much like the angle buttons in Radiant entity properties. For our doors we use the middle value that controls the rotating around the Z-axis, the axis rising from the XY plane, and thus the most natural axis for any door hinges. The starting position for an entity, as long as you haven''t hit the angle buttons, is 0 degrees, that is, straight to the right on the XY plane! So, even if our upper door points down, it's still facing zero degrees, when we start the game. Thus we need to turn it -90 degrees to open it toward the left room. Adjust the opening script to the lower door as well. You need to change the rotate command to 90 degrees instead of -90 degrees (take the minus away), and also take away the bogus door control command, which you must not have twice in the opening part of the script. After you are finished with the other door, minimize the trees, and insert a wait(7000) after the two affects. The wait means that the door will stay fully open for 4.5 seconds, after it has spent 2.5 seconds opening. Let's think for a moment the times. As you remember, you entered 10 seconds for the trigger Wait key. Now, if you consider the script, it takes 2.5 seconds for the doors to open and close. However, the time for them to stay open is reduced to 4.5 seconds. This mean the doors will stay closed for half a second, before they can be opened again (because the trigger won't launch again until the 10 seconds wait has passed). The half a second idle time is implemented to ensure proper areaportaling behavior. Your script (when the affects are minimized) should look like this: Fig 13. Both door affects and the wait. After this, you need to make the doors close after the staying open time is finished. For this purpose, copy the existing two affects, and paste them after the wait. Then proceed to edit them. I'll now post the whole script in Fig 14. You should by now know exactly what''s going on, so I will only explain it afterwards very shortly. Fig 14. The whole script for opening and closing the double doors and adjusting Areaportals! As you can see, the parts needed only for Areaportal adjustment are once again encircled with purple. Other parts are needed always. The latter affects will rotate the doors to the starting positions, thus all the rotate values have only zeroes; they are the absolute values for starting positions, of course. In the script we wait for the rotadoor1 to close, then we wait for an additional period of 200 ms just to be sure, and only then close the bogus door. The areaportal is returned. Of the trigger's 10 seconds wait time, 300 ms is left for the areaportaling to update, before reopening of the doors is possible. Now you only need to save your script. You must give it the name you used with the "usescript" key in the target_scriptrunner. After saving, just hit the Compile button. Now you are finished! Just ship the script with your level, in "scripts/mymapname" directory (in our case "scripts/rotamap"). Close BehavEd, compile your map and launch it in JA. You will see that once you go near the door, inside the trigger, the script will launch and the door will open! After a while, it will close. If you implemented the Areaportal, you can check whether it works by using the console command: r_showtris 1 Closing Remarks It wasn't hard at all, was it? Have nice time implementing this methods in your own maps. And remember that you can rotate objects which ever way you want. So, you can have trapdoors in the roof, or floor, wherever you want. You can even divide the door into four parts and open it like a flower. These images show you the door while it is closing. Areaportaling has worked properly, as you can see while looking at the picture on the right. You cannot see anything from the other room while having r_showtris 1 turned on.

    Shader Remapping

    Originally written by Seto Title: Shader Remapping Subject: How to Remap shaders (Swap one for another on the fly) Written by: Seto Tutorial written for: Jedi Academy Similar concept work like in: N/A Difficulty level: 5/10 Expected time to complete for first attempt: 15 mins Prerequisites: Intermediate familiarity with mapping, entities, shaders, and GTK Radiant Overview Shader remapping is a technique that is not obvious in GTK Radiant, but knowledge of its uses can lead to many interesting and unique features in your map. There are two entity keys called "targetshadername" and "targetshadernewname" that can be applied to certain target and trigger entities to have the game instantly remap all instances of a particular shader (or plain texture) to another. Any entity that triggers targets should work, but the best options are trigger_always for permanent changes, target_relay for controlled changes, and target_delay for timed changes (the remap will occur after these entities trigger their targets, so you can create delayed remaps with target_delay). Do note that it will remap every single instance of one shader to another; there is no way to pick just one particular case. Also, remapping shaders that contain a lightmap might cause odd results, and certain properties of shaders are not inherited and cannot be transmitted, such as portals. Application Shader remapping can be used with any shader or texture, including those used by default on items and other entities. Let's say we decide to change the appearance of an item_force_boon entity. As we know, Force Boons look like this: This item uses a number of shaders, so for our example we will focus only on the two shaders of the "box" part: the outer hollow cube and the inner glow within. If the name of a shader is not known, we can find it by looking in the appropriate .shader file. In this case, we can look in assets1.pk3 to find the right .shader file (models.shader), and then use a text editor to scan this file until we find the names of the two shaders used by the Force Boon: models/map_objects/mp/force_boon -> the outer cube shader models/map_objects/mp/boon -> the inner glow shader Now that we know our two target shaders to be changed, we need to pick two new shaders to change them into. There are many, many possibilities here, but for this example I am going to choose these two: textures/common/glass_security_hex -> glass with a hexagonal design gfx/misc/mine -> the shiny yellow mine that Imperial Shuttle vehicles can drop Of course, you could use your own shaders too, just remember to use the full shader name. Now that we know both our shaders to remap and what to remap them to, we can add a remap entity to perform this for us. As mentioned earlier, the three most useful shader remap entities are trigger_always, target_relay, and target_delay (note that trigger_always is not compatible with the latest versions of Lugormod, but works fine anywhere else). If we want the remap to appear instantly when the map loads, we use trigger_always, while if we want the remap to appear only after being triggered by a specific action, we use either target_relay or target_delay. For this example, we will use target_relay. You will need to create two target_relay entities total, because we have two different shaders to remap. After linking them to an activator (like trigger_multiple), you will need to manually add the shader remap keys (targetshadername and targetshadernewname). Your final entities should look like this: { "classname" "target_relay" "targetname" "remap_boon" "targetshadername" "models/map_objects/mp/force_boon" "targetshadernewname" "textures/common/glass_security_hex" } { "classname" "target_relay" "targetname" "remap_boon" "targetshadername" "models/map_objects/mp/boon" "targetshadernewname" "gfx/misc/mine" } Assuming "remap_boon" is the target of your activator, upon use it will cause your default Force Boon items to change appearance from there normal form into something like this: Now if we want to change it back to its original appearance, we can follow a similar process of creating two target_relay entities, only this time they should look like this: { "classname" "target_relay" "targetname" "remap_boon" "targetshadername" "models/map_objects/mp/force_boon" "targetshadernewname" "models/map_objects/mp/force_boon" } { "classname" "target_relay" "targetname" "remap_boon" "targetshadername" "models/map_objects/mp/boon" "targetshadernewname" "models/map_objects/mp/boon" } Notice that we refer to the target shader by its original name, despite the fact that it has already been remapped to take a different appearance. When remapping shaders, always use the original shader name as the targetshadername, not any new shader you use in the remap. Further Uses and Restrictions To cause any shader to appear totally invisible, simply use "clear" as the value of targetshadernewname. This can be useful to create effects such as vanishing lava or forcefields. Shader remapping works with sky shaders, but when a skybox shader is remapped, any clients who are experiencing the remap for the first time will be hit by a brief moment of lag due to shader precaching. This only applies to skybox shaders, and does not affect any client who has already rendered the remap previously. Furthermore, if a skybox shader is remapped to a non-skybox shader, there is a high probability that clients will crash upon coming into view with it, so ALWAYS remap skies to skies. Remapping certain special shaders such as caulk and clips will be refused; remember, the primary purpose of shader remapping is simply to change the visual appearance of things, not their actual properties. Shader remapping may cause certain shaders to lose lightmap info. Shader remapping can be used on non-map shaders as well, such as UI components (console, chat icon, HUD images, etc) and even NPC/player textures. Screenshots Here are some screenshots of various shader remapping techniques in action. Tatooine sky shown in day and remapped to night. A different Force Boon remap, this one for a more evening feel. A view panel model with remapped screen to show the opening game logos. A lava pool shown normally and with the lava shader cleared (courtesy of BobaFett). The tauntaun vehicle NPC with remapped textures to match the dead tauntaun model. A remap of the chat icon and console. Both new shaders are animated. This concludes our lesson in shader remapping. Experiment on your own to create your own unique shader combinations.
  9. Subject: How to create teleports that can be switched on and off without scripting Written by: Szico VII Tutorial written for: JK3 Similar concept work like in: N/A Difficulty level: 8/10 Expected time to complete for first attempt: 0.5-1.5 hours Prerequisites: Proficiency with entities, linking and basic building "Toggleable" - My word for meaning "being able to be turned on/off (made active/inactive) You can download the example/source files for this tutorial here Okay, so you want to make a toggleable teleport do you? Okay, for this tutorial I'm not going to be creating any structures to be teleported between, I'm just going to show you the SETUP of a teleport and entities to make it toggleable. You will have to place the entities in your map in the relevant places on your own. Firstly you'll want to create your trigger brush (which the player has to touch to be teleported away) Cover it with the system/trigger texture as you would normally when creating a teleport, but don't go any further. Instead of making it a trigger_teleport, you need to make it a trigger_multiple. This is because for some reason, the trigger_teleport entity doesn't function properly when you try to make it inactive, plus you cannot start it as inactive (e.g when you load the map it starts OFF.) We simply have to make the trigger_multiple believe it is a trigger_teleport. (let this be called Trigger #1 from now on) Don't worry, its very easy. Now, create a target_teleporter and link the trigger_multiple to it, so the trigger points toward the target. (Ctrl+K) You'll notice this is how you'd create a normal teleport destination if you had been using a trigger_teleport. However, we need to add another step before the trigger_multiple will act as a teleport. For ease of this process, I recommend you place the target_teleporter right above the teleport, or somewhere close to it, far away from where you want he final teleport destination to be. Now, we're going to set the destination for the teleport. Create a target_position in the place where you wish your player to be teleported to, and then link it FROM the target_teleporter. The link structure should be as shown below: Trigger #1 -------> target_teleporter -------> target_position Remember, the target_position is where the player will be teleported TO, and the trigger_multiple where they will be teleported FROM. The target_teleport simply acts as a midway point which actually makes the trigger_multiple act as a trigger_teleport. From this point, there are now 2 ways to go about actually turning this trigger on and off. One is using quite a lot of entities, OR you can use less entities but some scripting. I personally think the scripting bit is easy, even nobody who has ever used BehaveED before should be able to do it. However I will show how to use the entity method, as it requires no scripting. For this tutorial I will be using a button (which can be pressed by the player) to toggle the teleport on/off. (You can also do it using say a func_breakable, which ''destroys'' your teleport or something like that when broken, but this is probably the best example. First, create the brush that will be your button, and texture it with an according texture. Then create a brush which encompasses the button, and make it a trigger_multiple. Add a noise key if you wish. DO NOT ADD A WAIT KEY. Check the ''Use Button'' box as well. Here you can go two ways, depending on whether you want the teleport to reactivate with the same switch, or a different one. For this tutorial I will assume you want just the one switch, as it is harder and a little more confusing. Select the trigger_multiple you just created (let it be called Trigger #2 from now on) and copy it, creating a duplicate trigger. However, check the box in the entity window that says ''Inactive'' for this trigger. (Let this one be called Trigger #3 from now on) Move both triggers aside from the button, move trigger #2 to the left, and trigger #3 to the right, as shown below: Now we need to make the other entities required for activating/deactivating the teleport when the button is used. I personally find it easier to put all the entities in and then link them afterward, but the order you do it is up to you. Here is how you should set it up in terms of linking. Trigger #2 ----------> target_delay -----------> target_activate -------> Trigger#3 Trigger #2 ----------> target deactivate-------> Trigger#1 Trigger #2 ----------> target deactivate-------> Trigger#2 Trigger #3 ----------> target_delay -----------> target_activate ----->Trigger#2 Trigger #3 ----------> target activate --------> Trigger#1 Trigger #3 ----------> target deactivate ------> Trigger#3 Give both target_delays' the following keys. Key: wait Value: 4 It should look similar to this setup now: This is how your overall setup SHOULD look by now (Remember, Triggers #1, #2 and #3 are all actually trigger_multiples''): Trigger #1 ----------> target_teleporter ---------> target_position Trigger #2 ----------> target_delay --------------> target_activate -------> Trigger#3 Trigger #2 ----------> target deactivate ---------> Trigger#1 Trigger #2 ----------> target deactivate ---------> Trigger#2 Trigger #3 ----------> target_delay --------------> target_activate -------> Trigger#2 Trigger #3 ----------> target activate -----------> Trigger#1 Trigger #3 ----------> target deactivate ---------> Trigger#3 Triggers #1 and #2 both start off active (useable), but not Trigger #3 (due to you checking the ''inactive'' flag). As trigger #1 starts active, the teleporter will start active. When you press the use key whilst in Trigger#2, the following will happen. It will fire all its targets, initiating the following events. Firstly, it will deactivate itself, and Trigger #1. (The teleport) Then, after 4 seconds (due to the wait key we put on the target_delay) it will activate Trigger #3. The teleport will not function at this point - it has been turned OFF. To turn it back on again, go now to Trigger #3 and use it. The following will happen. It will fire all its targets, initiating these events. Firstly, it will deactivate itself, and ACTIVATE Trigger #1 (The teleporter.) After 4 seconds it will re-activate Trigger #2, allowing the cycle to start again. However, you will notice that we have 2 triggers used to operate the teleport, but only one button. If you want the 2 buttons in separate places, simply create another button, and place Trigger #2 over the one which will DE-ACTIVATE the teleport, and trigger #3 over the one which will RE-ACTIVATE it. If you want to operate the teleport from the same switch, drag BOTH triggers'' #2 and #3 into exactly the same place around the centre button. They should be exactly the same size and shape. Due to the 4 second delay between you can press the next trigger in the sequence, there should be no problems in-game. The final result is as shown below. Of course, you can also have the sequence the OTHER way around e.g the teleporter starts INACTIVE, and you have to activate it. To do this simply give check the ''Inactive'' box on both Triggers'' #1 and #2, and uncheck the ''Inactive box'' on Trigger #3 You can download the source files at the top of this tutorial Adding a Teleporter effect Ok, so you've setup your teleporter sequence, and button, but how can people tell whether the teleport is on or not without actually trying it? Most teleports which can be turned on or off give some indication of which state they are in, on or off, so now I''m going to show you how to do this. First of all, choose an effect for your teleport. This could either be a brush/patch with a fancy glowing shader, a light, an fx_runner or something similar. All can be used in a similar way. For this tutorial, I shall be using a patch with my teleporter shader on it. I have also added a teleport model to the setup. Here is the teleporter model with the effect in a temporary location. The teleporter model will never disappear, but the effect inside it will - by the time we are finished. But first things first. Select your effect brush/patch and make it into a func_useable. Depending on whether your trigger_multiple (Trigger #1) is set to start off or on, check the ''Start Off'' flag for this the newly created func_useable accordingly. Now, create another trigger_multiple exactly the same size and shape as Triggers #2 and #3. It shall be called ''Trigger #4'' Check its ''Use Button'' flag. Give it the following key: Key: wait Value: 4 This wait value corresponds with the delay between Trigger #2 deactivating and Trigger #3 activating, so that the teleporter effect and the trigger_multiple which actually teleports the player won't go out of sync with each other. Now target this trigger (Trigger #4) at your func_useable Now it's time to finish this thing off. Drag Trigger #4 into exactly the same place as Triggers'' #2 and #3 - You now have three trigger_multiples in the exact same place, but due to the delays and wait values we have implemented everything should work smoothly. Also move your teleporter model (or move Trigger #1 to the teleporter model) so that when you go into the teleporter field you will appear to be teleported. Final setup in Radiant is as shown below. And here's what it looks like ingame: And there you have it - A toggleable teleporter, complete with cool effects. You can also implement the func_useable effect on the button itself, by making 2 buttons, turning each separately into a func_useable (giving one an ''off'' texture and one an ''on'' texture, and using the ''startoff'' flag on the ''on'' switch, then targeting both with Trigger #4 (As well as the teleporter effect). Experiment around and have a go! The overall entity setup if you've followed me this far will be: Trigger #1 ----------> target_teleporter ---------> target_position Trigger #2 ----------> target_delay --------------> target_activate -------> Trigger#3 Trigger #2 ----------> target deactivate ---------> Trigger#1 Trigger #2 ----------> target deactivate ---------> Trigger#2 Trigger #3 ----------> target_delay --------------> target_activate -------> Trigger#2 Trigger #3 ----------> target activate -----------> Trigger#1 Trigger #3 ----------> target deactivate ---------> Trigger#3 Trigger #4 ----------> func_useable(s) All done!
  10. Title: Shadowing Effects and Alpha shadowing Subject: How to create cool looking shadows that are well defined. Written by: Szico VII Tutorial written for: JK3 Similar concept work like in: N/A Difficulty level: 4/10 Expected time to complete for first attempt: 10 mins Prerequisites: Ability to map basic structures, create entities and to implement shaders. You can get shadows normally in JK3 simply by design, as the engine usually calculates reasonable shadows for you. But what if you want that special effect to enhance the atmosphere, chances are, you're gonna need to do it manually. This tutorial will go over the basics of creating cool, more realistic and defined shadows, using the alpha shadowing techniques. You will end up with something like this: The Setup First off, you'll want to find the area of your map which you want the cool shadowing on. Make sure you have a light source for the shadows, and I highly recommend it is shader-lit, with a fairly strong glow. In the example above, I have a texture of various control panels, which is emitting yellow light. This is covered by a brush with a grate texture on it. The same setup is repeated with the white light at the top, except I have used a less powerful light there and a different grate texture. So here is what you need to do: Create a square room and texture the ceiling and walls with ''textures/doomgiver/basic.'' Texture the floor with your light emitting shader, as shown below. If you do not have a light-emitting shader, you will need to make one. For testing purposes, you may use the shader given below. The image it refers to is just a solid 4x4pixel yellow square. Light emitting-shader: (Copyable version shown below) textures/mymap/yellowglow { qer_editorimage textures/mymap/yellowglow q3map_surfacelight 500 q3map_lightRGB 1.00 0.99 0.42 { map $lightmap } { map textures/mymap/yellowglow blendFunc GL_DST_COLOR GL_ZERO } { map textures/mymap/yellowglow blendFunc GL_ONE GL_ONE glow rgbGen identity } } Getting the grates put in: Once this is complete, you need to add your grate texture and shader. You can simply borrow one of Raven's grate textures, (make sure it is a .tga with an alpha channel or an equivalent png) however, you will need to give it a new shader, as we are going to give it alpha shadowing. Alpha shadowing is a technique whereby light can pass through some areas of a texture but not others. Which areas it can pass through is determined by its alpha channel. Transparent areas, light will go though, not transparent areas, it won't. Without this command, light wont go through the texture at all regardless of the presense of an alpha channel. Here is the shader -(Copyable version shown below) textures/mymap/grate { qer_editorimage textures/imperial/grate02 surfaceparm nonopaque surfaceparm trans surfaceparm alphashadow cull twosided qer_trans 1.0 { map textures/imperial/grate02 alphaFunc GE128 blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA depthWrite } { map $lightmap rgbGen identity blendFunc GL_DST_COLOR GL_ZERO depthFunc equal } } Now we are ready to apply the shader, so go back to your map and create a brush covering the entire floor space, which lines up about halfway between the floor and ceiling (You can change this for different shadow effects later,) as shown below. DON'T FORGET TO MAKE THIS A DETAIL BRUSH! (Select it and hit Ctrl+ M) Now, turn this brush into a func_group. Give it the following keys and values: Key: _castshadows Value: 1 Key: _lightmapscale Value: 0.1 Next, select all surfaces you want shadows to be cast onto by this particular light source (In this case, all the walls textured with the doomgiver/basic texture.) Make these brushes also into a func_group and give it the following keys and values. Key: _recieveshadows Value: 1 Key: _lightmapscale Value: 0.1 Now add in a player spawn, and compile! You should get something looking as follows: Of course, you can mess about with the light shader colours and strength, different gratings, and try moving the grating closer or further from the light source for different effects. You can also use higher _lightmapscale values on your func_groups if your map is very large and the light compile is taking ages, but never go higher than 0.99 (as 1 is the default) This will give you reduced shadow precision and quality however. For example, in the shots below, I have tried lowering the grating. You may have spotted that the shadows look a little grainy toward the bottom. Making your texture repeat less will solve this, as will adding a small ambient light or perhaps putting the light source closer to the grate, or, as shown in the shot below, reduce the strength of the light (I also changed the texture used). As a final note, if you want to add new brushes to your func_group, if you realise there is a brush you left out, simply select first the brush, and then a brush in the func_group. Right click in the 2D view, and go ''Move into Entity.'' Remember, if you want to cast shadows onto a brush which is already an entity and cannot be made into a func_group, you should just add the same keys and values as you would if it were a func_group. And of course this will work with brushes as well as alpha shadowed textures - just follow the same principle, make the brushes you want cast shadows and voila! But, there is one last thing. Sometimes, shadows require color, for example, when light is shining through coloured glass. For this kind of shadow, there is an extra command you must add to your shader. It is: surfaceparm lightfilter This uses the colors in the texture to generate the colours for the shadows, so if you had a green texture, you''d get a green shadow.
  11. Title: Updating the compiler (Q3map2) Subject: How to update your BSP compiler Written by: Szico VII Tutorial written for: GTK Radiant 1.4.0 Similar concept work like in: N/A Difficulty level: 5/10 Expected time to complete for first attempt: 5mins Prerequisites: Text editor. Before you do anything, you''ll first need to download the most recent version of q3map2 (the BSP compiler program.) This is the box that comes up when you compile a map and goes through loads of lines, and the -meta -vis and -light stages. Download Q3map2 for 64bit Windows You will also need a text editor with a ''Replace text'' function, I used Notepad/Wordpad. How to update: First, you''ll need to locate your GTKRadiant-1.4 directory. As default this is C:/Program Files/GTKRadiant-1.4 - You then want to unzip the files in the .zip you just downloaded into this folder. This can be done using the Winzip in Wizard mode, and simply selecting the GTK Radiant program directory as the folder to unzip files to. This will automatically place the files where they need to be. If you then browse to the folder, you should see a new subfolder called ''q3map2'' that should look like this: Inside this folder there is another subfolder called 'extras' which should contain the files shown below. Okay, so we've imported the new files into the right directory. Now we just need to tell radiant to use these new files instead of the old ones. This is where you need your text editor. Browse to the following directory: JKA/GameData/base/scripts Here you will see a file called ''default_project.proj'' and perhaps others such as ''user0.proj,'' ''user1.proj,'' and so on and so forth. We need to edit all of these project files, so let's get cracking. Open the first file (default_project.proj) using Notepad or Wordpad. It will look different in notepad due to the formatting - it will be hard to read and contain lots of square symbols, so I advise using Wordpad, although it isn't necessary really. Now, either hit Ctrl+ G or go Edit>Replace to bring up the text replacement window. In the ''Find what'' box, type q3map2. In the ''Replace with'' box, type q3map2/q3map2, as shown in the picture below, and press the ''Replace All'' button. SAVE THE FILE (Ctrl+ S) (Make sure you are saving it as .proj and not .txt if you decide to save it using the menu.) Repeat this process for any further project (.proj) files you have in your scripts folder, saving each one. Next time you load up Radiant, and compile a map from the menu, it will use the updated compile. You can check that it is by having a quick look at the header of the box as you begin compiling. You should see the lines "2.5.16" and "Voter turnout" if you have done it correctly. If you haven't done it correctly, you'll get an error pop up in the compiler box. To fix this you should find the GTK Radiant install.exe file and run it''s repair function, and then try editing the project files again. Congratulations, that's it!'
  12. Long time no see I will definitely try this out shortly as you have put the effort to make it work as you did with moonbase!
  13. @mjtThat would be very much appreciated Could you share your batch file? Perhaps just one where the map can be dragged onto it to run the compiler (all 3 stages?) Many thanks again Oh, and I might take you up on the tour at some point but Im off to a mates stag this weekend so will rain check for now, if thats ok?
  14. @mjtthanks for nice words when ita done all source files will be included as usual. What is POM stand for? alpha blend functions will blend both the diffuse and the normal/parallaxmaps , I am not sure how it would work with a decal shader + parallaxmap though Ball would be nice as an NPC but I don't know how to do this myself as never used any character modelling stuff and not really keen to worry about that side of things unless it's very straightforward and has a clear easy tutorial. I'm not sure what you are asking about the terrain. It's a brush trisoup in its entirety. The surface shader is a standard diffuse with an alphablended secondary texture for each blend, phong shaded and then the parallax and specular rend2 texture maps added.
  15. Hi @mjtI was referring to q3map2 not netradiant, I did see the link about the netradiant features from another post above in order to decide if its worth using, and how to make best use of it, I wpuld rrallynlike anlist of changes and any new compile parameters and what they do, so far I can find absolutely zero I also have no idea how to actually get this new q3map2 working in the first place. Simply replacing the old exe does not work and the various dll files are in a new structure compared with the 2.5.17 version in gtk 6.6
