Hi to all of you, I know it's been a while since the game is old but I'm currently creating a map via GTKRadiant, and after 2 days of searching, I'm stuck with a script_mover Let me explain : I found this tutorial: https://www.surfacegroup.org/tutorials/wet/simple_mover_part2/ I followed it to the letter except that I, it is not a tank, but a police car, to facilitate my life I downloaded it on Internet, in file .max, I opened in 3DSMax, the model consists of 3 groups: the body of the car, the windows and the siren, I, at first, converted into file .ASE , except that I discovered that in .ASE file is only assigned to static objects, so impossible to use with the script_mover, so I reconverted the model, from the .max file, into .md3 file, except that it displayed without textures in GTKRadiant, to remedy this problem, I downloaded the software Misfit Model 3D and I exported it, again, in .md3 file. At this moment I am told that there are too many vertices on my model, I merge the vertices, and ... miracle, the file is exported correctly. The file opens so in gtkradiant with its texture, I give it the value and key classname: misc_gamemodel,targetname: police_car_ascriptname: police_car_a as shown in the tutorial above I compile my map in .bsp file, and the copy in my file /etmain / maps But when I launch it in Enemy territory, I get this message: So I exported the 3 groups (body, glass, siren) each of their sides, each is a targetname and a scriptname as in the tutorial except that when I run my map the game freeze and stops So I changed the lines "attachtotag ... tag _...." by reversing the two entities and my map is launched but the model remains invisible ... I hear the sound of script_mover but without the model. I also tried to put a "misc_model" instead of "misc_gamemodel" but when the map starts my model remains static and seems not to be attached to the script_moverSo concretely what I would like to do is to lower the vertices of the car (the Pro optimizer, the Optimizer and the MultiRes are not great), would there be a way to "compress" them? And if in the process, someone would explain to me the line of the script "attachtotag police_car_a tag_police_a" What I do not understand here is what the "tag" represents Thank you in advance ! it will save my life !!!!! Here is my script and some pictures model + script_ mover
