AS3: add event listener to loaded AS2 SWF
Hi,
What I am trying to do is - simply load an external SWF into my AS3 code.
I then want to show it on my stage - and be able to catch the 'ROLL_OVER', 'ROLL_OUT' and 'MOUSE_CLICK' events that happen with the SWF,
meaning - I want to know when the user hovers over the loaded SWF and when he clicks on it.
If I load an external AS3 SWF - it all works fine, and I can trace the events successfully.
If I load an external AS2 SWF - in some types of AS2 banners I can catch the events, and in some - I can't.
It is important to note that I cannot control the loaded SWFs and I cannot code them in a different manner.
The way I load the external SWFs is like this:
Code:
var loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onLoaded);
loader.load(new URLRequest(externalSwfURL));
function onLoaded(evt:Event):void
{
// The reason I don't create the MovieClip like this is because I need to support
// both AS2 and AS3 that will be loaded, and loaded AS2 cannot be casted to 'MovieClip'
//var mc:MovieClip = MovieClip(evt.target.content);
// This method allows me to load both external AS2 and AS3 SWF files
var mc:MovieClip = new MovieClip();
mc.addChild(loader);
// Add the events that I want to track
mc.addEventListener(MouseEvent.ROLL_OVER , onMouseEnterSWF);
mc.addEventListener(MouseEvent.ROLL_OUT , onMouseLeaveSWF);
mc.addEventListener(MouseEvent.CLICK , onMouseClickSWF);
mc.x = 100;
mc.y = 100;
stage.addChild(mc);
}
What I have found out is that if the loaded AS2 SWF has a transparent button on top of it (a lot of them have that) -
then the mouse events aren't fired back up to my AS3 code ! They are somehow 'swallowed' inside the loaded AS2 SWF and not bubbled up.
If I try to load an AS3 SWF that has a transparent button as the top layer - it works, and still bubbles up the mouse events to my AS3 code.
Can anyone tell me why this happens ?
PS - if I load an AS2 SWF that doesn't have a transparent button as a top layer - than the mouse events ARE bubbled up to my AS3 code.
Here is a link to an AS2 SWF file that has the 'transparent button' that blocks the events from bubbling up to the AS3 code:
