Each SWF really should stop its own audio and clean up. Trying to clean up on a SWFs behalf is likely a maintenance issue.

Alex thanks for the additional info. swfloader.content.stop() prior to setting a new source in this case managed to stop the next swf at the beginning once it loaded. Not sure why this happened. I did a bit of testing here and as far as I can tell when a MovieClip's loaderInfo dispatches an Event.UNLOAD the MovieClip itself has already been de-referenced. The timeline audio continues to play however. I've managed to fix this problem (although this seems a bit of a hack) by calling SoundMixer.stopAll() in the unload handler. I somehow doubt that this actually deletes the Sound objects that were created so my guess is that this could cause a big leak if many SWF's with timeline audio were being loaded over and over. Perhaps the same problem would persist even with SWF' with manually instantiated audio? Here's my quick fix. MovieClip(event.target.content).loaderInfo.addEventListener(Event.UNLOAD, unloadHandler); private function unloadHandler(event:Event) : void { SoundMixer.stopAll(); } --- In [email protected]<mailto:flexcoders%40yahoogroups.com>, Alex Harui <[EMAIL PROTECTED]> wrote: > > I haven't used this event to shut down a movie, so I don't have examples, but I think the recommended pattern is that the loaded SWF is supposed to listen for the UNLOAD event on its loaderInfo. If the main app is listening, then you're probably right that it is too late. Of course, if you're about to set the SWFLoader's source you can certainly call swfloader.content.stop() beforehand, but I think stop() doesn't stop Audio/Video, just the frame timeline. You'll have to have access to the loaded SWFs Sound instances which is why it is "better" if the loaded SWF cleans up after itself. > > From: [email protected]<mailto:flexcoders%40yahoogroups.com> > [mailto:[email protected]<mailto:flexcoders%40yahoogroups.com>] On Behalf Of djepyon > Sent: Tuesday, September 09, 2008 8:35 PM > To: [email protected]<mailto:flexcoders%40yahoogroups.com> > Subject: [flexcoders] Re: SWFLoader unloading, whats the trick? > > > Thanks guys.
