[SCRIPT] Particle Effects help

[Smackdown]

hey there!


First things first: I've searched several times and I didn't find anything helpfull.

I want that dust falls down when the player passes a script area. (e.g. ScriptArea_4) So I've tried it with activate like with other objects. But it didn't work. I know I have to do something with "CreateParticleSystemAtEntity"

here are my tries:

void OnStart()
{
...
AddEntityCollideCallback("Player", "ScriptArea_4", "staub", true, 1);
...
}


void staub(string &in asParent, string &in asChild, int alState)
{
PlaySoundAtEntity("", "28_done03.snt", "Player", 0, false);
SetEntityActive("ParticleSystem_17", true);
SetEntityActive("ParticleSystem_19", true);
CreateParticleSystemAtEntity("E1PS", "ps_debris_tunnel.ps", "ScriptArea_4", true);

}

Can anyone help me?
