If a project doesn't have an audiocontroller.h/.m, can it be imported or do I need to create them in Xcode?

"Usually" BT_audio.m is enough for most purposes; it's included in the 'core' files. It allows you to play audio files throughout your buzztouch project. What were you planning to do? Cheers! -- Smug

I know how to have music play in the background over the whole app but what I'm trying to achieve is having the main screen have one music file that plays only on that screen & the quiz have another music file that plays only on that screen. I've been reading and looking at tutorials (ex. RAY WENDERLICH) and can't figure out how to implement this. Any help is appreciated.

#import <AVFoundation/AVFoundation.h> should do the trick

Well... a little work, but it's all good in the end. First, find and locate "playSoundEffect". It's in your appDelegate file, around line 786-ish. Copy that method (play sound effect) and paste it... Then change it to look like this: //stopSoundEffect... -(void)stopSoundEffect { [BT_debugger showIt:self message:[NSString stringWithFormat:@"stopSoundEffect %@", @""]]; for(int i = 0; i < [self.soundEffectPlayers count]; i++){ AVAudioPlayer *tmpPlayer = (AVAudioPlayer *)[self.soundEffectPlayers objectAtIndex:i]; if(tmpPlayer){ [tmpPlayer stop]; } } } There. Now you have matching methods; one for start, and one for stop. For each audio file, be sure to add it to your array of soundeffect names. This is done in BT_loadConfigDataViewController.m, around line 403 or so... add your audio files the same way. [appDelegate.soundEffectNames addObject:@"yourfilename.mp3"]; Now, in each plugin you want to use this in, just put '[self stopSoundEffect];' somewhere in viewDidLoad and put '[self startSoundEffect:@"yourfilename.mp3"]; in viewWillAppear of the 'target' plugin. So basically 1) Add your music to the bundle. 2) Add your filenames to the array of soundeffects. 3) At the beginning of a plugin load, 'stop' the music. 4) At the end of a plugin load 'start' the new music. Hope this helps. Cheers! -- Smug

Thanks so much! Getting the following errors though: [self startSoundEffect:@"yourfilename.mp3"]; brings up: Expected identifier or '(' Use of undeclared identifier 'self' [self stopSoundEffect]; brings up: No visible @interface for 'BT_screen_quiz' declares the selector 'stopSoundEffect'

Oh... you want something that *works*. Why didn't you say so. ;) Instead of 'self', try '[appDelegate startSoundEffect:@"yourfilename.mp3"]; you may need to do the same for the stop method as well. Also, you 'might' need to declare appDelegate if it goes red on you. That's fairly common, and should be an example somewhere in your plugin code. It'll look sort of like this: BT_appDelegate *appDelegate = (BT_appDelegate *)[[UIApplication sharedApplication] delegate]; Let us know how it goes... Cheers! -- Smug

Haha. I would love for it to work! ;) Getting same errors as before but now with "appDelegate" instead of "self" BT_appDelegate *appDelegate = (BT_appDelegate *)[[UIApplication sharedApplication] delegate]; is present in the project too.

Oh, for that 'visible interface selector' issue, you'll need to add that method to the appDelegate.h file as well. It'll look something like this: -(void)playSoundEffect:(NSString *)theFileName; -(void)stopSoundEffect; 'playSound Effect' will already be there. Just 'add' stopSoundEffect when you find it. Cheers! -- Smug

Ok. Added '-(void)stopSoundEffect;' Still getting this. [appDelegate startSoundEffect:@"Dawn.mp3"]; brings up: Expected identifier or '(' Use of undeclared identifier 'appDelegate' [appDelegate stopSoundEffect]; brings up Use of undeclared identifier 'appDelegate'

Well, that appDelegate needs to be called in the method just before the '[appDelegate stopSoundEffect];'. and it proabably won't be 'BT_appDelegate'... it changes the name to whatever your app name is. so, if you named your app "JoesGarage" it should say 'JoesGarage_appDelegate' instead of 'BT_appDelegate'. Do a search in any odd plugin for 'appDelegate' and you'll soon see what I mean. You'll get there. persistance and patience are key elements in this wrestling match. Cheers! -- Smug

Everything I have found references this in my project: namethathorror_appDelegate *appDelegate = (namethathorror_appDelegate *)[[UIApplication sharedApplication] delegate]; Now in my namethathorror_appDelegate.h this is below '#import <AVFoundation/AVFoundation.h>' in the project: @interface namethathorror_appDelegate:UIResponder <UIApplicationDelegate,AVAudioPlayerDelegate>{ AVAudioPlayer *appDelegate; } Is this correct or could it be causing an issue?
