list particle id while runtime?

hi there,

I am trying to list the particle ids of a certain position in an array so I can kill them at a specified frame. But if I want to access the array it ends up in an infinity loop.
What am I doing wrong?

//runtime

int $currentFrame = frame;
vector $pos= particleShape1.position;
int $pi;
int $IdList[];
int $IdListRemove[];
int $count = 0;
int $go = 1;


//list ids
if($pos.x < locatorKill.translateX && $pos.x > locatorKill.translateX - 0.01 && $go == 1){

$pi = particleShape1.particleId;
$count = size($IdList);

if ($pi != $IdList[$count]){
$IdList[$count] = $pi;
}
}

// kill particles at frame 1100
if ($currentFrame == 1100 && $go == 1){
$IdListRemove = $IdList;
$go = 0;

for ($i = 0; $i < $size; $i++){
particle -e -at lifespanPP -id $IdListRemove[$i] -fv 0 particle1;
}

}



thank,

First, where do you declare/ define $size?

Next...wouldn't it be easier to do it the following way (pseudomelcode):


//only execute script on frame 1000
if($frame == 1000)
{
	float $minY = locatorKill.translateY;
   float $minX = locatorKikk.translateX;

   //go through your particles
   
float $pPos =   myParticleShape1.position;

if(($pPos.x < $minX) && ($pPos.y < $minY))
{
	myParticleShape1.lifespanPP = 0;
}


That should do it.

thanks for the reply,

basically it worked, but then maya kept on complaining about some ids:

// Error: Could not find particle with id specified. Please check id value in the query command //


but it works for now if I just suck the particles out of the way with a goal instead of killing them.


thanks
