A simple custom event

you must ensure that aperture doesn't play that frame until door is ready to receive that event.  you can always stop the aperture timeline until door is ready, that's what you must do.  there's no way to work around that potential issue except to prevent it from occurring.

once you've done that you can call dispatchEventF() in Aperture to dispatch your event to Door.

var doorRef:MovieClip
       
        function Aperture(){
        }
        function addlistenerF(mc:MovieClip){

doorRef=mc
        }

function dispatchEventF(whatever){

if(doorRef){

doorRef.dispatchEvent(new Event("ce"));

}

}
    }
}

            this.addEventListener(Event.ADDED_TO_STAGE,init);

        function init(e:Event){
            this.addEventListener("ce",listenerF);
            MovieClip(MovieClip(this.parent.parent).loaderB.content).addlistenerF (this);
        }

            trace(e)
        }

kglad,

Are you referring to "use weak references" in the event listener?  If not can you provide an example of what you mean. I did some googling on reference and event dispatching and no much seems to come up that would explain what you mean.  I also looked in some of my books and got the following info on references, but not sure how it  applies to what you are saying.

Info from book:

assignment where the source variable’s value is an instance of a custom class or an instance of a built-in class other than String, Boolean, Number, int, or uint, ActionScript associates the second variable directly with the first variable’s value. After the assignment, only one copy of the value exists in memory, and both variables refer to it.

Thanks for the help.
