    copied!<p>I made a toggle button in cocos2d located in the title screen of my game. I want this toggle to turn the music either on or off. This is what I have done so far:</p> <p>I added the CCMenus and Sprites to the .h file:</p> <pre><code> CCMenu *menu2; CCMenu *menutwo; CCMenuItemImage *sound; CCMenuItemSprite *soundOff; </code></pre> <p>Then I added the sound button and the NSUserDefaults in the init:</p> <pre><code>// Sound Button sound = [CCMenuItemImage itemWithNormalImage:@"music.png" selectedImage:@"music.png" target:self selector:@selector(soundSettings)]; sound.scale = 1.1; menu2 = [CCMenu menuWithItems:sound, nil]; menu2.position = ccp(screenCenter.x - 33,screenCenter.y / 5); [self addChild:menu2]; if([[NSUserDefaults standardUserDefaults] objectForKey:@"musicon"] == nil) { [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:@"musicon"]; } </code></pre> <p>This is the soundSettings Method called above by the CCSprite:</p> <pre><code>- (void) soundSettings { if([[NSUserDefaults standardUserDefaults] boolForKey:@"musicon"] == TRUE) { [self removeChild:soundOff cleanup:YES]; [self removeChild:menutwo cleanup:YES]; sound = [CCMenuItemImage itemWithNormalImage:@"music.png" selectedImage:@"music.png" target:self selector:@selector(soundIsOff)]; sound.scale = 1.1; menu2 = [CCMenu menuWithItems:sound, nil]; menu2.position = ccp(screenCenter.x - 33,screenCenter.y / 5); [self addChild:menu2]; } else if ([[NSUserDefaults standardUserDefaults] boolForKey:@"musicon"] == FALSE) { [self removeChild:sound cleanup:YES]; [self removeChild:menu2 cleanup:YES]; soundOff = [CCMenuItemImage itemWithNormalImage:@"music-not.png" selectedImage:@"music-not.png" target:self selector:@selector(soundIsOn)]; soundOff.scale = 1.1; menutwo = [CCMenu menuWithItems:soundOff, nil]; menutwo.position = ccp(screenCenter.x - 33,screenCenter.y / 5); [self addChild:menutwo]; } } </code></pre> <p>These are the 2 methods being called by the toggle CCSprites:</p> <pre><code>-(void) soundIsOn { [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:@"musicon"]; } -(void) soundIsOff { [[NSUserDefaults standardUserDefaults] setBool:FALSE forKey:@"musicon"]; } </code></pre> <p>Since this code is located in the Title Screen, this only stops the music for the title screen. As soon as I go to another screen, the music BOOL resets and becomes TRUE again. If anyone can help me out with this, I would really appreciate it. Thanks!</p> <p><strong>Note:</strong> This is how I will be checking to see if the music is on or off:</p> <pre><code>if([[NSUserDefaults standardUserDefaults]boolForKey:@"musicon"] == TRUE) { [[SimpleAudioEngine sharedEngine] playEffect:@"song.mp3"]; } </code></pre>
