Particle System Collision Area?

Question

so I've got a bunch of modules called "c4" labled red1,red2,red3, etc. And a laser made from particles, with angle controlled
by bckspace and enter keys:
onEnterFrame = function(){
for (m=1;m<4;m++){
c4 = this["red"+m];  
if(robot_mc.laser_mc.lasereye_mc.hitTest(c4.cap)){c4.gotoAndPlay("frame2"); }
    //laser controls
    if(Key.isDown(Key.BACKSPACE)){robot_mc.laser_mc._visible = true; robot_mc.laser_mc.lasereye_mc._rotation -= 7;}
    if(Key.isDown(Key.ENTER)){robot_mc.laser_mc._visible = true; robot_mc.laser_mc.lasereye_mc._rotation += 7;}
    if(!Key.isDown(Key.BACKSPACE) && !Key.isDown(Key.ENTER)){robot_mc.laser_mc._visible = !true;}
for(i=0;i<500;i++) {
    photons = this["photon"+i];   
    var k:MovieClip = robot_mc.laser_mc.lasereye_mc.attachMovie("photon","photon"+i ,robot_mc.laser_mc.lasereye_mc.getNextHighestDepth());
        k._xscale = Math.random()* 120 - 20;
    k._yscale = Math.random()* 180 + 35;
    k._y -= Math.random()* 10 +10;             //plus changes distance of start of beam, base changes range
        k.gotoAndPlay(Math.ceil(Math.random()*16));    }
The problem I run into is having the collision work with the beam, as opposed to the bounding box that begins with the
lasereye_mc. Is there a way to get the c4 to react with the beam, instead of the bounding box around the beam? Or a way to get the photons to interact individually? Also, is there a way to load a particle system through an onEnterFrame without it overloading/oversaturting ?    Thanks.

Answer 1

ok, so I added the remove movieclip at the end of the particle timeline,
and then cut down the i<500 to i<80, and added the c4.cap hitTest;
for(i=0;i<80;i++) {
    photons = this["photon"+i];   
    var k:MovieClip = robot_mc.laser_mc.lasereye_mc.attachMovie("photon","photon"+i ,robot_mc.laser_mc.lasereye_mc.getNextHighestDepth());
        k._xscale = Math.random()* 120 - 20;
    k._yscale = Math.random()* 220 + 35;
    k._y -= Math.random()* 15 + 10;             //plus changes distance of start of beam, base changes range
        k.gotoAndPlay(Math.ceil(Math.random()*16));   
            for (m=1;m<4;m++){
        c4 = this["red"+m];   
    if(c4.cap.hitTest(k)){c4.gotoAndPlay("frame2"); }
            } //end c4 for loop
    } // end photon for loop
and duplicated the loop for the c4 module. It now works like a charm ^_^
Thanks much!
