[SCRIPT] ParticleSystem not disappearing

[i3670]

I have this little problem in my "Insanity Event"-thingy. When you enter an area alot of particle system become active and a chase moment occurs. It's just that if the person dies the particlesystems are still active ruining the entire thing.

SCRIPT:

Spoiler below!

void OnStart()
{
AddEntityCollideCallback("Player", "Trigger_Area_1", "Event_trigger1", false, 0);
SetEntityPlayerInteractCallback("diary_paper01_1", "Interact1", true);
}

void Interact1(string &in asEntity)
{
SetEntityActive("Trigger_Area_1", true);
CheckPoint ("One", "PlayerStartArea_2", "Reset_1", "", "");

}
