Example of Pause and Resume

The ability to pause and resume the Director within Cocos2D makes it relatively easy to implement a game’s pause and resume button.

     

Important: Scenes/Nodes doesn't support the CocosNodeOpacity protocol.

     

Pausing the Game

     

The director pauses the current scene, and SimpleAudioEngine pauses the background music.

     

[[CCDirector sharedDirector] stopAnimation];

[[CCDirector sharedDirector] pause];

[[SimpleAudioEngine sharedEngine] pauseBackgroundMusic];

     

Resuming the Game

     

The director resumes the current scene, and SimpleAudioEngine resumes the background music.

     

[[CCDirector sharedDirector] stopAnimation];

[CCDirector sharedDirector] resume];

[[SimpleAudioEngine sharedEngine] resumeBackgroundMusic];

[[CCDirector sharedDirector] startAnimation];

     

For other unwanted cases, for example, when user got a Mobile Call, user presses on Home button you can do it through Application Life Cycles methods.

     

To Pause 

     

- (void) applicationDidEnterBackground:(UIApplication *)application

{

[[CCDirector sharedDirector] stopAnimation];

[[SimpleAudioEngine sharedEngine] pauseBackgroundMusic];

 [[CCDirector sharedDirector] pause];

}

     

- (void)applicationWillResignActive:(UIApplication *)application

{

[[CCDirector sharedDirector] stopAnimation];

[[SimpleAudioEngine sharedEngine] pauseBackgroundMusic];

[[CCDirector sharedDirector] pause];

}

     

To Resume

     

- (void)applicationDidBecomeActive:(UIApplication *)application

{

[[CCDirector sharedDirector] stopAnimation]; 

[[CCDirector sharedDirector] resume];

[[SimpleAudioEngine sharedEngine] resumeBackgroundMusic];

[[CCDirector sharedDirector] startAnimation];

}
