[OOP] Class Silent

Hi,

The following class I’ve coded fails to fade the MC on stage. Could someone explain why the code fails?


class FadeAlpha extends MovieClip {
	private var alpha:Number = this._alpha;
	private var visible:Boolean = this._visible;
	public var alphaRate:Number;
	public var mc:MovieClip;
	//constructor left enpty, can use later.
	public function FadeAlpha() {
		fadeObj();
	}
	function fadeObj(mc:MovieClip, alphaRate:Number) {
		mc.onEnterFrame = function() {
			mc.alpha -= alphaRate;
			if (mc.alpha<=0) {
				mc._visible = false;
				delete mc.onEnterFrame;
			}
		};
	}
}




//From AS Timeline:
import FadeAlpha;
var fadeAlpha:FadeAlpha = new FadeAlpha);
img01_mc.fadeAlpha(this, 5);

On Stage:
img1_mc
