[FMX] Controlling Sounds Across Multiple .SWFs

programming flash
1

I need a little advice. I’ve got a set of swfs that are all part of one training, and within these movies are a few sound effects attached to button instances. I want the user to be able to click a button to turn the sound on or off at any time during the training.

My first idea was to create a variable called wantSound, which each sound instance checks before deciding to play. This is working perfectly. There’s a toggle switch on the main timeline that sets sound to on or off, and when a sound is supposed to play, it checks to see if wantSound=true, and plays, or if it is false, it does not.

This works fine on each individual .swf, but when a new .swf loads in, the sound defaults back to true, and the user has to turn it off again. I imagine this could be fixed by loading each movie into different levels instead of loading them into level0 or root, but as this is not how I originally created the file, that will take a lot of work to handle aligning the loaded movies and parking them (making sure none of the buttons are active on the level below). I’m lazy, what can I say? :slight_smile:

I’ve been looking around at similar questions, and found a decent tutorial on Macromedia’s site about using javascript to pass a variable from flash to HTML. I went through that, and managed to get Flash to send my wantSound variable to HTML with no problem. Check here for the tutorial.

The only problem is that in macromedia’s example for sending data from HTML back to Flash, they use a text field for getting the variable. I just want to take the variable sent from Flash to HTML and send it back to Flash when requested (at the beginning of the next SWF.)

Are there any javascript masters out there that can rewrite THIS without using a text field or button or link?

Am I going about this all the wrong way? :beam:

Excerpted for your ease, this is the code from the tutorial:
In HEAD tag:
[AS]<SCRIPT LANGUAGE=JavaScript>
<!–
function doPassVar(args){
var sendText = args.value;
window.document.myFlash.SetVariable(“wantSound”, sendText);
alert (args);
}
//–>
</SCRIPT>[/AS]

In body tag:
[AS]<form name=“form1” onSubmit=“doPassVar(sendText);” action="#">
<input type=“text” name=“sendText” maxlength=“45” onChange=“doPassVar(this);”>
</form>[/AS]
