Flex to Flash communication with SWFLoader

- Problem:

Create communication between flex and flash swf when using SWFLoader.

note: embeding a swc might be the solution for some people. I use it a lot, it works fine. But this time I want to load at run time. Don’t want to embed because it would increase the size of my flex swf.

- Solutions:

– - Local connection

Source code here, “Save Link As” on your desktop and change extention to .zip

- – Event Access (best solution)

Source code here, “Save Link As” on your desktop and change extention to .zip

- Conclusion:

It works but you need to be carefull with the local connection. Don’t forget to close it.

I recommand the access through event in combination with DTO (data transfere object) to pass variables.

I have yet to look into this but in this link:

Even more interesting

The guy load the class definition of the external swf file opening the door to an open communication between 2 swf fully knowing each others variables and functions, isn’t it?

<pre>package com.scottgmorgan {
     import flash.display.Loader;
     import flash.net.URLRequest;
     import flash.events.Event;
     import flash.display.LoaderInfo;
     import flash.display.Sprite;
     import flash.system.ApplicationDomain;
     public class SourceMovie extends Sprite {
          public function SourceMovie():void {
               var loader:Loader = new Loader();
               loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
               loader.load(new URLRequest('ExternalMovie.swf'));
          }
          private function onLoadComplete(e:Event):void {
               ApplicationDomain.currentDomain.getDefinition("com.scottgmorgan.ExternalMovie");
               var myExternalMovie:ExternalMovie = ExternalMovie(e.target.content);
               myExternalMovie.alert('Hello World');
          }
     }
}
