Simple eventdispatcher problem

1

hi guys,

its me again, i recently learned “eventdispatcher” and how it is used to call custom event on various cases.

so i got this btn(button) within nav(mc) on stage which dispatch an event and call a function in the end.

(hierarchy: stage > nav > btn)

i have 3 bunch of codes in 3 location. here they are:

myEvent.as

package {
    import flash.events.EventDispatcher;
    import flash.events.Event;
    import flash.display.MovieClip;

    public class myEvent extends EventDispatcher {
        public static  const GO:String = "go";

        public function act():void {
            dispatchEvent(new Event(myEvent.GO));
            trace("act called");
        }
    }
}

main timeline (frame1)

var dispatcher:myEvent = new myEvent();

dispatcher.addEventListener(myEvent.GO, actionHandler);

function actionHandler(event:Event):void {
    trace("Event Called");
}

nav (frame1)

var dispatcher:myEvent = new myEvent();
btn.addEventListener(MouseEvent.CLICK, buttonClickHandler);

function buttonClickHandler(event:MouseEvent):void {
    dispatcher.act();
}

  1. When you click btn, the “buttonClickHandler” fired and it calls act from dispatcher.

  2. “act called” traced and its supposed to call the event, but its not.

do you know how to fix this problem?

  • if you put the nav code in main timeline. and change the code to the following. it works
nav.btn.addEventListener(MouseEvent.CLICK, buttonClickHandler);

function buttonClickHandler(event:MouseEvent):void {
    dispatcher.act();
}

but i don’t want that, i’m curious why the code inside nav doesnt work.

attached is the file, more understandable

thanks a bunch guys.
