Adding Force Fall to Outcast sp

May 31, 2016

Hi everyone, obviously this can be done for Academy sp with serenity's tutorial, but I'm having difficulty implementing it in Outcast. You see, most of the code for Academy goes under the wall grab segment in pm_addevent but when I put the Force Fall code under pm_addevent in Outcast, it fails compiling. Anyone able/willing to shed light or help me with this?

May 31, 2016

I got 4 errors I'm hoping someone can help me with.

if (FFDebounce + FORCEFALLDEBOUNCE < pm->cmd.serverTime)
{
if (pm->ps->velocity[2] < FORCEFALLVELOCITY)
{
if ((FORCEFALLVELOCITY - pm->ps->velocity[2]) < ForceFallBrakeRate[pm->ps->forcePowerLevel[FP_LEVITATION]])
{
pm->ps->velocity[2] = FORCEFALLVELOCITY;
}
else
{
pm->ps->velocity[2] += ForceFallBrakeRate[pm->ps->forcePowerLevel[FP_LEVITATION]];
}
}
}

// is it time to reduce the players force power
if (pm->ps->forcePowerDebounce[FP_LEVITATION] < pm->cmd.serverTime)
{// FP_LEVITATION drains force mana only when player
// has an upward velocity, so I used FP_HEAL instead

WP_ForcePowerDrain(pm->gent, FP_HEAL, FM_FORCEFALL + ForceManaModifier);

2 of them is "forcefallbreakrate" undeclared identifier.
WP_forcepowerdrain, identifier not found.
Last one is "Intellisense, forcefallbreakrate, undefined.

Could someone help me please

ForceFallBrakeRate seems to be some variable that controls (surprise) the braking rate of the force power. I think it's a float array, but I'm not sure.

Anyway, what file is this in? Whatever it's in, try adding this:

float ForceFallBrakeRate[] = {
   0.9,
   0.8,
   0.7,
   0.6,
   0.5
}

Those values aren't guaranteed and you might need to tweak them.

P.S. this is precisely why I hate copy-paste tutorials like that one, that literally don't explain anything.

Hi pal, thanks for the help again. Its in bg_pmove.cpp. I'm still at it lol

May 31, 2016

HAHAHAHHAAHAHAHAHAHAHAHAHAHAHAHAHAHAHAH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I did it

There has seem to be a problem with the code. So, what I've had to do is remove the force power drain bit from it and walla, its in, but I still want it to drain mana when used

Code snipped:

// // is it time to reduce the players force power

if (pm->ps->forcePowerDebounce[FP_LEVITATION] < pm->cmd.serverTime)

{// FP_LEVITATION drains force mana only when player

// has an upward velocity, so I used FP_HEAL instead

WP_ForcePowerDrain(pm->gent, FP_HEAL, FM_FORCEFALL + ForceManaModifier);

// removes force power at a rate of 0.1 secs * force jump level

pm->ps->forcePowerDebounce[FP_LEVITATION] = pm->cmd.serverTime + (pm->ps->forcePowerLevel[FP_LEVITATION] * 100);

}

eezstreet · June 1, 2016

Well if you add that code back, and change the third argument of WP_ForcePowerDrain, it will work correctly. The third argument should be however much force power you want to drain from the player (FP_HEAL here is ignored).

Try this:

// // is it time to reduce the players force power
if (pm->ps->forcePowerDebounce[FP_LEVITATION] < pm->cmd.serverTime)
{// FP_LEVITATION drains force mana only when player 
// has an upward velocity, so I used FP_HEAL instead
WP_ForcePowerDrain(pm->gent, FP_HEAL, 1); // Change this 1 to some other number to increase/decrease how much force power gets drained.
 
// removes force power at a rate of 0.1 secs * force jump level
pm->ps->forcePowerDebounce[FP_LEVITATION] = pm->cmd.serverTime + (pm->ps->forcePowerLevel[FP_LEVITATION] * 100);
}

Alright pal, thanks again for you're time. I'll give it a shot and get back to you with the result.

Still gives an error, won't work at all.

I got alittle question for you redemption, when kyle use force fall by a very high roof and he hurt the land, if the force fall is again active he take damage from falling or not? because in my SP code mod force fall work, but when player touch the land get however damage by the falling (and if i not shield my jedi with force protect before jump and use force fall in pit, he can die on impact with ground) .

well, i have the hobby of modding JKA by 12 years... but i did ever this as self didactic learning with try and error and following some tutorials. basically psykosith tutorial for models and rich diesal for mapping.

only in 2013 i found this beatiful community and my modding skill boosted up. also, learning the basic of coding allow me to really deep change the gameplay. now i can really make the dream of my project: a conversion of JKA for revive the deleted legacy of kain series, i am a big fan of kain and raziel histories.

the unique code issue i get is just some little crash again to fix and the force falling, force falling emulate the vampiric skill of jump of blood omen 2 game. it's identical, so when serenity up that code, i add in the mod immediatly.

but i need again to fix the factor of the damage on the crash land. mmm i will check the things related to damage and the pm_crashland function. maybe the answer is here.

for the rest, i have alls for my project: models and code are ready. i need just to make a large amount of visual effects for elemental projectiles and spells and .... Maps... argh, this is my damnation! How can i recreate in 3d nosgoth world with the radiant poly limitation? maps of JKA need to be LOW poly. MD3 helps for building and i am okay for houses and trees etc.

but lands... uff... make terrains on JKA is nasty >.<

i discover a procedure for convert Blood Omen level maps into heightmap and realize 3d terrain but these height map that are the same aspect of nosgoth scturutale lands, but is very long as process...

mmm, maybe another solution is to find MD3 prefab of cliff, montains, hills, gorges, etc etc... o.o

The idea is too implement the force fall code like how when you roll before you land it diminishes the damage you take. I've seen the code for this but failed at making the force fall version of it. Next idea is to check the OJP code, any help?

maps are the baddest problem. JA map material is too sci - fi for nosgoth ambientation.

awww... interessing idea. reduce after rolling D:

well maybe something like if NPC_setanim blablabla rolling animation

damage \ =

mmm for reduce damage check into g_combat the code related to hazardtrooper saber resistance. search in g_combat.cpp

MOD_SABER \= 10 and you see an example of damage reduction.

also demp2 code offer an example, but in the opposite sense

damage *= 7 ;

you can set something like damage \= 3; or MOD_FALLING \= 3 or MOD_IMPACT, i not know what kind of MOD is applied to impact with land.

the problem is not the dmg, is the IF field. because i not know how to make something AFTER an animation. is possible to make during an animation, but after... you need a little more expert help.

@@Asgarath83 - Thanks again friend, Its MODCRUSH I believe. Where the code to reduce damage if you roll on landing, there is also a jump statement as well but the roll one would be the one I'm looking at. I'll post the roll code up in a wee while, cause I think you could figure a way to make it work as when in force jumping animation, we reduce falling damage there :-)

Hello again This is the roll code and under it is what I've attempted. Not tried it yet but just uploading so you can see the code.

// FIXME: if duck just as you land, roll and take half damage

{//must be crouched and have been inthe air for half a second minimum

Asgarath83 · June 15, 2016

Hello again Hope all is well with you're worlds. Okay, The force fall tutorial doesn't really work as it should. The part where you add:

if (PM_InForceFall())

return;

... to "static void PM_CrashLand( void )" doesn't nullify fall damage. I think the damage decision for jumping is maybe located here:

if ( pm->ps->pm_flags&PMF_TRIGGER_PUSHED )
	{
		delta = 21;//?
		forceLanding = qtrue;
	}
	else
	{
		if ( pm->gent && pm->gent->NPC && pm->gent->NPC->aiFlags & NPCAI_DIE_ON_IMPACT )
		{//have to do death on impact if we are falling to our death, FIXME: should we avoid any additional damage this func?
			PM_CrashLandDamage( 1000 );
		}

		if (pm->ps->jumpZStart && (pm->ps->forcePowerLevel[FP_LEVITATION] >= FORCE_LEVEL_1 || !pm->ps->clientNum))
		{//we were force-jumping
			if (pm->ps->origin[2] >= pm->ps->jumpZStart)
			{//we landed at same height or higher than we landed
				if (pm->ps->forceJumpZStart)
				{//we were force-jumping
					PM_CrashLandDamage(delta);// was forceLanding = qtrue;
				}
				delta = 0;
			}
			else
			{//take off some of it, at least
				delta = (pm->ps->jumpZStart - pm->ps->origin[2]);
				float dropAllow = forceJumpHeight[pm->ps->forcePowerLevel[FP_LEVITATION]];
				if (dropAllow < 1024)// 128
				{//always allow a drop from 128, at least
					dropAllow = 1024;// 128
				}
				
				if (delta > forceJumpHeight[FORCE_LEVEL_1])
				{//will have to use force jump ability to absorb some of it
					PM_CrashLandDamage(delta);//absorbed some - just to force the correct animation to play below// was forceLanding = qtrue;
				}
				delta = (delta - dropAllow) / 3;
			}
			
			if ( delta < 1 )
			{
				delta = 1;
			}
		}

		if ( !delta )
		{
			delta = PM_CrashLandDelta( pml.previous_velocity, pm->waterlevel );
		}
	}

Now I've messed with this problem since my last posting here. My idea is either (a) add the force fall return code before the jump stuff under PMF_TRIGGER_PUSHED; but don't know how to do it properely due to the else thing-wee-majif being there or (b) this:

if (pm->ps->jumpZStart && (pm->ps->forcePowerLevel[FP_LEVITATION] >= FORCE_LEVEL_1 || !pm->ps->clientNum))
		{//we were force-jumping
			if (pm->ps->origin[2] >= pm->ps->jumpZStart)
			{//we landed at same height or higher than we landed
				if (pm->ps->forceJumpZStart)
				{//we were force-jumping
					PM_CrashLandDamage(delta);// was forceLanding = qtrue;
				}
				delta = 0;
			}

if (pm->ps->jumpZStart && (pm->ps->forcePowerLevel[FP_LEVITATION] >= FORCE_LEVEL_1 || !pm->ps->clientNum))
		{//we were force-jumping
                if (pm->ps->jumpZStart - pm->ps->origin[2])
			delta = (pm->ps->jumpZStart - pm->ps->origin[2]);
				float dropAllow = forceJumpHeight[pm->ps->forcePowerLevel[FP_LEVITATION]];
				if (dropAllow < 1024)// 128
				{//always allow a drop from 128, at least
					dropAllow = 1024;// 128
				}
				
				if (delta > forceJumpHeight[FORCE_LEVEL_1])
				{//will have to use force jump ability to absorb some of it
					PM_CrashLandDamage(delta);//absorbed some - just to force the correct animation to play below// was forceLanding = qtrue;
				}
				delta = (delta - dropAllow) / 3;
			}
			else
                        if (PM_InForceFall())
	                {
		            return;// or put here - forceLanding = qtrue; then delta = 0
	                }

What d'you'se think? Any thoughts/ideas?

Asgarath83 · June 15, 2016

Oh... FFS, I've done it again! HAHAHAHAHAHAHAHAHAHAHAHA!!!!!!!!!!!!!!!!

So far, this is what seems to have done the trick

if (pm->ps->jumpZStart && (PM_InForceFall()) && (pm->ps->forcePowerLevel[FP_LEVITATION] >= FORCE_LEVEL_1 || !pm->ps->clientNum))
		{//we were force-jumping
			if (pm->ps->origin[2] >= pm->ps->jumpZStart)
			{//we landed at same height or higher than we landed
				if (pm->ps->forceJumpZStart)
				{//we were force-jumping
					PM_CrashLandDamage(delta);// was forceLanding = qtrue;
				}
				delta = 0;
			}

Adding "(PM_InForceFall())" in the if thingy...Argument??? Thank you all who gave me a bit of their time, thank you.

Well I think that I've answered it myself, so how do I go about marking this topic as answered??

Edit... Found it
