SetImageTrigger

Hi after implementing

Jim biffy bots by Stefan Beffy Moises
and
AI SENSES by Daniel Neilsen

brillent scripts both of you too so thanks are in order. though i am having a problem firing.
im getting this error -

starter.fps/server/scripts/aiPlayer.cs (204): Unable to find object: '' attempting to call function 'setImageTrigger'

Accoring to the script it should be firing though for some reason it cant find this object. i would post the *.cs file here but instead ill include it as a link. Click Here for script

this is the problem piece of code.

function Armor::singleShot(%this)
{
// The shooting delay is used to pulse the trigger
%this.setImageTrigger(0,true);
echo( "singleShot" );
%this.setImageTrigger(0,false);
%this.trigger = %this.schedule(this.shootingDelay,singleShot);
}

it proberly jsut hates me. i did get the bot to fire by moving this piece of code %this.setImageTrigger(0,true); to the onShoot area and changing %this.setImageTrigger(0,true); to %obj.setImageTrigger(0,true);

I hope some one can help as ive tryed my best as a noobie to get this to work.

Thanks alot

Nick
