How do you play preloaded music? The documentation doesn't give much detail into all of the functions of 'SimpleAudioEngine'
backgroundAmbience = [SimpleAudioEngine sharedEngine];
if (backgroundAmbience != nil) {
[backgroundAmbience preloadBackgroundMusic:@"ambience.mp3"];
if (backgroundAmbience.willPlayBackgroundMusic) {
backgroundAmbience.backgroundMusicVolume = 0.5f;
}
}I preload the music but then how do I get 'backgroundAmbience' to play?
Thanks

Yes I know, but I want to be able to stop and start specific preloaded music files and it will be easier to manage if they are under names such as 'backgroundAmbience' rather than having to do long code all the time which could get messy. When you preload the music, it is stored to the name is it not? How can you play the preloaded music rather than just pulling is straight away with [[SimpleAudioEngine sharedEngine] playBackgroundMusic:@"background-music-aac.caf"];

Don't blame the documentation because things don't work the way you think they should. Everything SimpleAudioEngine can do is defined in the header file. Basically you can't do what you want to do. However, I would have thought someone worthy of the title "WizKid" would be able to look at the source and see how backgroundMusic is implemented. Some code like the following should be all you need:
CDLongAudioSource *music = [CDAudioManager sharedManager].backgroundMusic;
[music load:@"filename.mp3"];
[music play];However, bear in mind that you can only have one backgroundMusic track loaded at a time and when you load another one you have to be sure you have stopped the previous backgroundMusic. This is because we want backgroundMusic to have access to hardware decoding for performance reasons and only one file at a time can be using hardware decoding.

Thanks that was what I was looking for. I looked at the source code and tried to figure out how to do it but had no luck. The documentation just lacks detail, I wasn't beating it. It provides useful basic info, however doesn't cover the advanced bits. Incase I missed something, this is what I was looking at: http://www.cocos2d-iphone.org/wiki/doku.php/cocosdenshion:cookbook
I assume that the object to play music has to be 'CDLongAudioSource' like a sprite has to be 'CCSprite'?
FYI: I called myself JavaWizKid because I love java and learnt it at a young age and thought it was appropriate. Cocos2d has nothing to do with it because I don't know the engine inside out.
Thanks anyways :)
