Functions, variables and attachMovie

[colmmac]

Hey,
I've been trying to figure out this flash tutorial all day:
http://www.newgrounds.com/portal/view/325278
and it's really wrecking my head - maybe someone can help?

It's a really cool effect but the tutorial's really badly written.
In trying to follow it, what I've basically done is create a flash file containing one movieclip called "bug" in which I've drawn just a little white dot.

Then in the main scene I've pasted the following actionscript (which I
got from the tutorial) into the first keyframe:

fly = function () {
this.animate = function() {
// Capture mouse positions and distance from mouse
this.targetX = _root._xmouse;
this.targetY = _root._ymouse;
this.distX = this.targetX-this.meX+this.flockX;
this.distY = this.targetY-this.meY+this.flockY;
//
if ((this.targetX == this.oldTargetX) && Math.random()>0.9) {
// add small scale random darting if mouse is still
this.flockX = (Math.random()*100)-50;
this.flockY = (Math.random()*100)-50;
} else if ((this.targetX<>this.oldTargetX) && Math.random()>0.8) {
// add large scale random darting if mouse is moving
this.flockX = (Math.random()*400)-200;
this.flockY = (Math.random()*400)-200;
}
// Apply inertia equation
this.meX = Math.round(this.meX+(this.distX)/20);
this.meY = Math.round(this.meY+(this.distY)/20);
// perform animation
this._x = this.meX;
this._y = this.meY;
// remember the current mouse pos so we can tell if
// it has moved next time around
this.oldTargetX = this.targetX;
};
this.initialize = function() {
this.targetX = 0;
this.targetY = 0;
this.distX = 0;
this.distY = 0;
this.meX = this._x;
this.meY = this._y;
this.oldTargetX = 0;
this.flockX = (Math.random()*200)-100;
this.flockY = (Math.random()*200)-100;
};
// set up onEnterFrame script to animate _parent...
this.initialize();
this.onEnterFrame = this.animate;
};
//
//
var i:Number = 0;
var bugClip:MovieClip;
for (i=0; i<30; i++) {
bugClip = this.attachMovie("bug", "bug"+i, i);
fly.apply(bugClip);
}

Apparently, once I export this it should work, but it ain't. Nothing happens.
I've a feeling the problem lies somewhere in the last few lines of
code, either with the variable or attachMovie command.

I was wondering if maybe someone might be able to figure it out.
Thanks!

Sorry mate, I have a hard time looking at code like this and finding out the problem...never done anything like it before. I'll send this on, to see if anyone else has some ideas.
