Algodoo

the fire srcipt put it on on collide: (e)=>{
for(1, (x)=>{
Scene.addCircle({
_Temperature := 1600;
timeToLive := 0.5;
radius := 0.5;
pos := e.pos;
edgeblur := 7;
update := (e)=>{
_Temperature = sim.running ? _Temperature - 4 : _Temperature;
radius = timetolive / 4;
colorHSVA = {
[timetolive * 40, 0.9, timetolive * 6, (timetolive * 100) / 70]
}
};
collideSet := 2;
heterocollide := false;
drawBorder := false;
drawCake := false;
onCollide := (e)=>{};
density := 0.0005;
vel := rand.normal2D * 10;
zDepth := rand.normal * 100
})
})
}

wtf?

Oh wow what a big script!
