[away3d] swf loading external swfs

[bryan rickertsen]

This may just be a molehill issue, but since there is lots of molehill
expertise in this group, I am hoping someone can suggest a way to find
a solution.

I am working on a video game.  I began in Papervision3D in 2010.
Because of unsatisfactory performance, I converted to Away3D 3.6/FP10
in early 2011.  Also for performance reasons, the strategic design of
the game involves creating each game level in its own swf and using a
master swf to unload the current swf level and load the next swf game
level when needed.  The strategy worked in Away3D 3.6/FP10.  However,
on slower machines the game ran at only 2-4 fps.  So I am now
converting to Broomstick/Molehill.  The game levels are great in
Broomstick/Molehill and we are even enhancing some of our graphics.
However, in Broomstick/Molehill, I am not able to make the same swf
loading logic work.  Here is my loader logic:

package {
        import flash.display.MovieClip;
        import flash.events.Event;
        import flash.events.MouseEvent;
        import flash.media.Sound;
        import flash.net.URLRequest;
        import flash.display.Loader;


        public class Test1Stub extends MovieClip {
                public var swfcounter:int=0;
                public var loader:Loader=new Loader  ;
                public var mcExternal:MovieClip;
                private var startup:Startup;
                public var Introswf:MovieClip;
                public var Playerdimensions:Object;


                public function Test1Stub():void {
                        startup=parent as Startup;
                        loadswf();
                }

                function loadswf():void {
                        this.addChild(loader);

                        loader.load(new URLRequest("Test1.swf"));
                        
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,swfIn);
                }

                function swfIn(e:Event):void {
                        loader.x=0;
                        loader.y=0;
                        
loader.contentLoaderInfo.removeEventListener(Event.COMPLETE,swfIn);
                        Introswf=loader.content as MovieClip;
                        loader.addEventListener("close",unloadSWF);
                }
                function unloadSWF(event:Event):void {
                        loader.unloadAndStop();
                        removeChild(loader);
                        loader.removeEventListener("close",unloadSWF);
                        loadnewswf();
                }
                public function loadnewswf():void {
                        startup.stepAhead("Test2");

                }
        }
}

Also, in the swf to be loaded, I use this logic:

if (stage == null)
                {
                        
this.addEventListener(Event.ADDED_TO_STAGE,addstagelisteners);
                }
private function addstagelisteners(e:Event):void
                {
                        stage.frameRate = 30;
                        createUI();
                        stage.addEventListener(Event.ENTER_FRAME,onEnterFramex);
                        init()
                }

Does anyone have any idea why this would work for FP10 but not FP11,
or how to make it work in FP11.

Thanks for your help.
