Hi good people of Kirupa!

I’m writing a very simple class, which is meant to affect the movieClip “ball\_mc”. All I want it to do is to randomize its (ball\_mc) properties (.\_alpha, .\_x, .\_y etc).

```auto

import mx.utils.Delegate;

class move {
	private var t_mc:MovieClip;
	
	public function move(t:MovieClip) {
		t_mc = t;
		randomize();
		
	}
	
	private function randomize():Void {
		t_mc.onEnterFrame = function() {
			this._x += randNum(-100, 100);
		}
	}
	
	private function randNum(min:Number, max:Number):Number {
		var n:Number = (min + Math.floor(Math.random() * (max - min)));
		trace(n);
		return n;
	}
	
}

```

I guess this could be a job for Mr. Delegate, but I don’t get it to work properly. The problem is that is won’t call the randNum function, due to scoping issues I suspect. The “onEnterFrame” works fine.

Any hints guys? Thanks in advance.
