delete this.onEnterframe function?

[podenphant]

To avoid unneccesary onEnterFrame checks I wonder if i can delete it after '} else {'. I dont want to removeMovieClip.

onClipEvent(load) {
    function expand(endSize) {
        this.onEnterFrame = function  () {
            var myHeight = _height;
            if(_height < endSize) {
                myHeight = myHeight*1.2 + 1;
                if(myHeight > endSize) {
                    myheight =endSize;
                }
            } else {
                myheight =endSize;
            }
            _height = _parent.mask._height = myheight;
            _parent.videoplayerbg._y = _parent.player._y = myheight + 7;
// delete the onEnterframe function?
        }
    }
} 

Any thougts or cool tricks out there?
