EventManager Example

Going to keep this short for now but I wanted to upload some example files for the EventManager to help anyone having trouble understanding it or getting it working.  I’ll post more soon about any specific questions people have but for now I’ve got to run and earn my rent money.

Here are the example files that use the classes from the tutorial:

   Great tut!
   How would I reference the child object that dispatched the event from within the parent object that was listening?

   e.g. with a standard listener event you can do:

   function ($Event:Event):void{
   trace($Event.target.parent); //Return the object’s reference.
   }

   Cheers,

   A way I’ve found to reference the object that fired the event is to pass data with the custom event.
   I don’t like this way though, as it breaks encapsulation.
   I’m not sure if there’s a way of actually passing a pointer/reference to an object like in C++ – I didn’t think that was possible in AS3…?

   This is what I was looked at to modify the custom event to pass data: http://flexcomps.wordpress.com/2008/04/29/dispatching-custom-events-in-as3-with-data-or-object/

   There must be a betta way?

   ok…
   To retain encapsulation I just stuck a getter on ma custom event:

   public function get Info():*{
   var TempInfo:* = _PassedInfo;
   return TempInfo;
   }

   The OOP Gods are now happy!

   So now to get whatever info is passed to the event I just use $Event.Info e.g.

   private function TriggeredEvent($Event:MaCustomEvent):void{
   trace($Event.Info);
   }

   and when dispatching I pass whatever I want to know:
   dispatchEvent(new MaCustomEvent(MaCustomEvent.ONCLICK, “U KNOWS IT WERKS!”)
