trap_R_SetFog & trap_R_SetGlobalFog usage

(=POP= Saigon) #1

Hi all,
I’m trying to code shellshock in our mod Price of Peace such as ShellShock in Call ofDuty.

After some explorations, i found two interisting API calls: trap_R_SetFog & trap_R_SetGlobalFog.

But I got some problems.

1st: trap_R_SetGlobalFog scrashes ET!!!
2nd:trap_R_SetFog, works fine and get nice fog effect, but i can’t restore original fog effect and the sky is blended or very bright and goldrush map looks like very sunny. After many hours spended to find how to restore, I need ur help ET fellows.

Here a synthetic snapshot of my code:

void CG_SetFogShellShock()
{
if (cg.shellshock)
{
float maxdensity = 0.7f;
float duration = 15 * 1000;
float elapsed = cg.snap->ps.shellShockElapsed;
float density = (maxdensity - ((elapsed / duration) * maxdensity)) / 100;

	if (density < 0)
		density = 0;

	trap_R_SetFog(FOG_CURRENT, 1, 5, 0.9, 0.9 , 0.9, density);
	trap_R_SetFog(FOG_CMD_SWITCHFOG, FOG_CURRENT, 20, 0, 0, 0, density);
}

}

void SomeWhereInMyCode()
{
playerState_t* ps;

blablabla;

if (ps->eFlags & EF_SHELLSHOCK)
{
	if ((cg.snap->ps.pm_flags & PMF_LIMBO) == 0
		&& cgs.clientinfo[cg.clientNum].team != TEAM_SPECTATOR
		&& !cg.showGameView )
	{
		float	v			= cg.time / 250;
		float	duration	= 15 * 1000;
		float	elapsed		= cg.snap->ps.shellShockElapsed;
		float	ratio		= (1.0f - (elapsed / duration));
		float	angle1		= 1.5 * ratio;
		float	angle2		= 2.5 * ratio;
		float	delta		= 1 * ratio;
		float	s			= sin(v);
		float	c			= cos(v);
		vec3_t	org;

		if (!cg.shellshock)
		{
			cg.shellshock = qtrue;
		}
		
		CG_SetFogShellShock();

		VectorSet(org, delta * c, -delta * s, delta * s);
		VectorAdd(cg.refdef_current->vieworg, org, cg.refdef_current->vieworg);

		cg.refdefViewAngles[0] += angle1 * c;
		cg.refdefViewAngles[1] += angle2 * -s;
		cg.refdefViewAngles[2] += angle1 * s;

		trap_S_FadeAllSound(0.4, 50, qfalse);
	}
	else
		trap_S_FadeAllSound(1.0, 0, qfalse);
}
else if (cg.shellshock)
{
	// reset fog to world fog (if present)
	cg.shellshock = qfalse;

// CG_ParseGlobalFog();
// CG_ParseFog();
trap_R_SetFog(FOG_CMD_SWITCHFOG, FOG_SERVER,0,0,0,0,0);
trap_S_FadeAllSound(1, 0, qfalse);
// dhm - end
}

blablabla…
