Loop background music in SpriteKit

I'm finishing a game for iOS done with the SpriteKit framework. I want to know if there is any way to loop background music while the user is playing. SpriteKit includes a simple music player but it does not allow looping music... So I want to know how could I accomplish this. Thanks!

In your scene class add:

Method 1:

self.run(SKAction.repeatForever(SKAction.playSoundFileNamed("music.mp3", waitForCompletion: true)))

Method 2:

self.addChild(SKAudioNode(fileNamed: "music.mp3"))

You can do this in two ways.

First:

1) @import AVFoundation; //Import this in AppDelegate file

2) @property (nonatomic) AVAudioPlayer * backgroundMusicPlayer; //Define a property in AppDelegate file

3) under didFinishLaunchingWithOptions delegate method in AppDelegate file wrote below code

NSError *error;
    NSURL * backgroundMusicURL = [[NSBundle mainBundle] URLForResource:@"bg" withExtension:@"wav"];
    self.backgroundMusicPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:backgroundMusicURL error:&error];
    self.backgroundMusicPlayer.numberOfLoops = -1;
    [self.backgroundMusicPlayer prepareToPlay];

4) Now you can use backgroundMusicPlayer property in any class like below code

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate.backgroundMusicPlayer play];

Second:

If you want to use SKAction Use below code

SKAction *wait = [SKAction waitForDuration:10.0];
        SKAction *performSelector = [SKAction performSelector:@selector(playEffectBgSounds) onTarget:self];
        SKAction *sequence = [SKAction sequence:@[performSelector, wait]];
        SKAction *repeat   = [SKAction repeatActionForever:sequence];
        [self runAction:repeat];

-(void)playEffectBgSounds{

    //Play Sound
    [self runAction:[SKAction playSoundFileNamed:@"chick.mp3" waitForCompletion:NO]];

}

You can use AVAudioPlayer for this purpose:

In your .h:

#import <AVFoundation/AVFoundation.h>

and add the following to interface

AVAudioPlayer *player;

In .m, initialize player with audio oath url:

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                             pathForResource:@"bg_music"
                                             ofType:@"mp3"]];
player = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:nil];
player.numberOfLoops = -1;

and when you need to play the audio, you can call:

[player play];

Note: "numberOfLoops" is the number of times that the sound will return to the beginning upon reaching the end.

  • A value of zero means to play the sound just once.
  • A value of one will result in playing the sound twice, and so on...
  • Any negative number will loop indefinitely until stopped.

Keep Coding................ :)

I'd rather use SKAction:

[SKAction repeatForever:[SKAction playSoundFileNamed:@"hello.caf" waitForCompletion:YES]];

or:

[SKAction repeatAction:[SKAction playSoundFileNamed:@"hello.caf" waitForCompletion:YES]
                 count:100];
