Question

I see how to add a image file to a CCSprite but how can I also add a audio file?

Is the an attribute I can store a map or dictionary?

FYI I’m on a mobile device posting this so code is not an option right now, will try to update my question

UPDATE:

What I’m trying to do is associate an audio file with each CCSprite and on touch drag play the audio file.
Each CCSprite will play a different audio file.
I’m trying to figure out the easiest way to either attach or associate the audio file with the CCSprite

Answer 1

OK, here is the approach I’d prefer, depending on whether you are playing a “background music” sound or an “effect” sound:

If you are playing an MP3 sound, ie background music:

1) Add a parameter to the sprite constructor to assign a sound file:

[MySpriteClass spriteWithSound:@"mySound.mp3"];

2) Simply use:

// on touchDragged:
[[SimpleAudioEngine sharedEngine] playBackgroundMusic:self.sound];

// on touchEnded: touchCancelled:
[[SimpleAudioEngine sharedEngine] stopBackgroundMusic];

NOTE: This approach is simple because you can only play one BGM at any given time.

If you are playing an uncompressed sound, ie effect:

1) Add a parameter to the sprite constructor to assign a sound file:

[MySpriteClass spriteWithSound:@"mySound.caf"];

2) Play the effect on touchDragged: while storing the return value:

// on touchDragged:
soundID = [[SimpleAudioEngine sharedEngine] playEffect:self.sound];

3) Stop the effect on touchEnded: using the soundID:

// on touchEnded: cancelled:
[[SimpleAudioEngine sharedEngine] stopEffect:soundID];

NOTE: This approach is better as it allows you to play more sounds at a time.

---

Final Remarks:

If you have subclasses of each different sprite (ie, FishSprite, DogSprite, … etc), such that ALL instance of any given class have the same sound, it would be better to add static method to return the sound name for that class:

// somewhere in DogSprite.m
+ (NSString *)soundName {
    return @"bark.caf";
}

And for the sake of completeness, add a superclass that implements the touchDragged:, touchEnded:, so you don’t have redundant code:

// on touchDragged:
soundID = [[SimpleAudioEngine sharedEngine] playBackgroundMusic:[[self class] soundName]];

// on touchEnded: cancelled:
[[SimpleAudioEngine sharedEngine] stopEffect:soundID];
