UIloader not completely unloading (music)

[jesseclark]

I have an application that calls external SWF files through the UILoader component. I do this so I can keep the file size smaller in the beginning and only load objects as the user needs. (if there is a better way to do this, please let me know).

Here is my problem. One of the objects plays music. In it's simplest form something like this:

var sound:Sound;
sound = new Sound( );
sound.load(new URLRequest("fightsong.mp3"));
sound.play();

From the first application, I load the second application and the music starts playing. However, when I unload the second application the music continues to play. The applications can not talk to each other (I assume) because it is basically one SWF calling another SWF via the UILoader.

In my first application, when the uiloader is closed I have:
theLoader.unload();

however the music continues to play. Any suggestions? Can the two SWFs communicate with each other? Is there an eventlistener for exiting? or is there a better way to handle this all together?

Thank You!

can't you stop the sound before you unload the loader?

And is this happening for you in FireFox or just IE or the swf itself, alone?

yes there is a stop button on the second application that will stop the music. But if they don't hit that, and the application gets closed before, then the music still plays. I need a way to automatically stop the music when it gets unloaded.

thx.

right, right, there are two swfs, i overlooked that, yes they can communicate -
you can use the LocalConnection object or even the external interface and add callBacks from one to another:

i'm used to doing it via the external interface:

in the one with sound, set up a function that can get called to stop the sound:

function stopSound():void
{
//do sound stop
//this functions code can be similar to the code you have on the stop button
}

//then set up a external interface callback that when called will invoke the above function

if (ExternalInterface.available) {ExternalInterface.addCallback("stopTheSound", stopSound);}

//now, this part is a bit fiddly , but you need to call a javaScript function that will call stopTheSound
//on the swf , so in your wrapper you'll have a function like this: 
 

<script type="text/javascript">
function callForTheSoundStop()
{
//it may take more than this to reference your swf, this is a general example
document.getElementById("theIdofYourSWF").stopTheSound();
}
</script>

//now, right before the second swf is to be unloaded, call:

ExternalInterface.call("callForTheSoundStop");

//and that should work, however i'm not sure how the fact that it's a swf inside a swf will effect things
//but that's a general solution and how i do things
//the normal way is via the LocalConnection

Thank you so much for your reply!

It seems kinda like a hack, having one swf file talk to the other via javascript but it works! This just saved me a TON of time. again, thank you very much!

cool, glad it worked for you!
