I’ve got an AS3 SWF that I’m going to be loading other SWFs into.

I’ve got an AS3 SWF that I’m going to be loading other SWFs into. These child SWFs all take a single parameter on the URL. I can’t seem to get it working when loading an AS2 child, and it needs to be able to handle both.

so I have 

var request:URLRequest = new URLRequest(); var loader:URLLoader = new URLLoader();  request.url = 'http://domain/as2.swf?param=foo'; loader.load(request); // etc on to the eventListeners, addChild, etc

When the as2 SWF gets loaded, it can’t see the parameter I’ve passed to it. It’s looking for _root.param. Am I doing this wrong or am I attempting the impossible?

EDIT: I should add that I can load a SWF with those URL params from an AS2 loader and it works just fine.

  1. It’s not trivial to communicate between AS2 and AS3 since they run in different virtual machines. Check this http://www.gskinner.com/blog/archives/2007/07/swfbridge_easie.html for some hints.

    Edit: If you cannot change the loaded as2 content your only options is creating a ‘wrapper’ as2 loader that uses the linked example above to communicate with the as3 and interfaces with the loaded as2 content using _root.varname This is not pretty but it might just work.
