[Xerte] Re: Problem looping sound controlled by script - Xerte 2 desktop

Mon Feb 7 09:48:13 GMT 2011

args is a global var. In a script function (think subroutine rather than function) you should snap off the args into vars that won't collide with anything else, because if you then call another function from that function, args will be the args sent to the second function. Once that's done, and you're back in the first function, args will hold values from the second function call. I don't use functions so often: sometimes it seems better to have a global event handler, and fire custom events from within the code.

I've gotten into the habit of fully qualified paths.

_level0.engine.fcommonPagesetup(arg);

If you have multiple functions and/or are using asfunctions as well, funny things happen, especially to the args[]

Thanks for suggestion, Dave.  We run all of our xerte rlo files from a flash application that plays in the browser.  I've found that inFunc scripts work in preview, but don't when played in our flash wrapper.  Didn't investigate because it was easier just to duplicate the code. Another layer of Flash sitting under the xerte engine confusing things?  Now that I have a real reason, I think I'll put some time into figuring it out.

Tried to use the onLoad event on the sound icon but it never fired.

Tried putting the load call in one script and the play call in a separate script but that magic didn't work.

Tried setting the isStreaming arg of the loadSound call to true and that actually worked but then I lost looping which was the whole reason I started down this path.

hmmmm... I'll play around with this.
Thanks

Thanks, Julian, you're absolutely right.

But now I'm trying to figure out how to implement this without a button for each task.  When I read the flash documentation it's all about defining a named or anonymous function that is invoked onLoad, which we can't do in xerte, right?

Is the sound loaded before you call start()? It might need to load before the method works. Try mocking up an interaction with a button to load the sound, a button to make it play, see if that works. In the engine I handle onLoad to control the autoPlay setting, so I think that's the right approach.

Hi Julian,

Things just got weird using this technique to control sound.  Haven't  had time to investigate yet, but thought I'd ask in case the answer is as easy for you as the last one was.
soundIcon.sound.stop();
soundIcon.loadSound(FileLocation + 'mySoundFile.mp3');
soundIcon.sound.start(0,100);

Accessing the flash sound object with these calls works fine when I play the rlo file in preview mode. iI also works when I play it from a flash swf file that loads it with this:
     attachMovie('Xerte', 'myRLO', 0);

But if I publish the rlo and try to play it in a browser, or if I play my flash "wrapper" in a browser I don't hear these sound files.  I do hear the other sounds in my rlo that I'm playing in the standard way.

Any ideas as to what's going on?

Thanks a million!

Easy.

Access the underlying sound object, mySoundIcon.sound and control it directly with the Sound object's methods

myIcon.sound.start(offset, loopCount);

I was feeling smug enough about controlling sound via script yesterday to dare to post an answer to someone's question!!  Ha!  The gods don't like hubris.

Today everything is different.

I've got a button that plays a sound when clicked. I'd like the sound to loop and the button to toggle it on and off

It seems to forget its loop value when I start controlling it via script.

mySoundIcon.play();

However if I just put the sound icon under a button icon and set it to play =1 and loop = 5, then the looping works and all is fine.  I can even stop it and reset it without any problems.  Just can't manage to play it from script more than one time.

Tried putting an onSoundComplete event to reset it and play it but it just went mad and looped very bizarrely without ever waiting to finish.

Then I tried the getSound route but can't seem to get the timing right so this always returns undefined.

Any ideas?  I think I must be missing something very simple.

Thanks!
