How do I access a movieClip on the stage using as3 class?

Question

public class MyClass extends MovieClip {
            public function MyClass():void {
                my_mc.addEventListener(MouseEvent.CLICK, action);
            }         


        

Answer 1

Try this:

public class MyClass extends MovieClip
{
    public function MyClass()
    {
        if (stage) init();
        else addEventListener(Event.ADDED_TO_STAGE, init);

    }// end function

    private function init(e:Event = null):void 
    {
        removeEventListener(Event.ADDED_TO_STAGE, init);

        var myMc:MovieClip = stage.getChildByName("my_mc") as MovieClip;
        // var myMc:MovieClip = parent.getChildByName("my_mc") as MovieClip;

        myMc.addEventListener(MouseEvent.CLICK, onMyMcClick)

    }// end function

    private function onMyMcClick(e:MouseEvent)
    {
        trace("clicked");

    }// end function

}// end class

If this doesn't work(which I don't think it will), its because your my_mc display object isn't a child of the stage, but the child of an instance of MainTimeline. If so, then simply comment out the following statement in the above code:

var myMc:MovieClip = stage.getChildByName("my_mc") as MovieClip;

and uncomment the following statement in the above code:

// var myMc:MovieClip = parent.getChildByName("my_mc") as MovieClip;

If my assumption is correct, the my_mc and myClass display objects share the same parent.
