if have a prototype like this

```auto

MovieClip.prototype.moveToXY = function(xPos, yPos) {
	this.onEnterFrame = function() {
		difx = xPos-this._x;
		dify = yPos-this._y;
		if (Math.abs(difx)>1 || Math.abs(dify)>1) {
			this._x += difx/5;
			this._y += dify/5;
		} else {
			this._x = xPos;
			this._y = yPos;
			delete this.onEnterFrame;
                        // ready
		}
	};
};

```

can i track that “ready” state with listener? -\> when the object has moved to new place x,y -\> other function should start…

because i’ll use that prototype with many mc:s i can’t call the function in that prototype!

so, can somebody help me?
