Creating Games with cocos2d for iPhone 2

By: Paul Nygard

Overview of this book

Cocos2d for iPhone is a simple (but powerful) 2D framework that makes it easy to create games for the iPhone. There are thousands of games in the App Store already using cocos2d. Game development has never been this approachable and easy to get started. "Creating Games with cocos2d for iPhone 2" takes you through the entire process of designing and building nine complete games for the iPhone, iPod Touch, or iPad using cocos2d 2.0. The projects start simply and gradually increase in complexity, building on the lessons learned in previous chapters. Good design practices are emphasized throughout. From a simple match game to an endless runner, you will learn how to build a wide variety of game styles. You will learn how to implement animation, actions, create "artificial randomness", use the Box2D physics engine, create tile maps, and even use Bluetooth to play between two devices. "Creating games with cocos2d for iPhone 2" will take your game building skills to the next level.

Tying it together


There are only two important methods left to review to tie this all together. First is the update method. Let's look at the applicable portions of the update method (we have left placeholders for the other portions of the update method, but those will not be addressed here. Please refer the code bundle for this book to see those details):

Filename: MXPlayfieldLayer.m

-(void)update:(ccTime)dt {
  
  for (MXMoleHill *aHill in moleHillsInPlay) {
        
    if (aHill.hillMole.moleState == kMoleHit) {
            [[aHill hillMole] setMoleState:kMoleMoving];
      [self scoreMole:[aHill hillMole]];
    }
  }
    
    if (molesInPlay < maxMoles && spawnRest > 10) {
        [self spawnMole:self];
        spawnRest = 0;
    } else {
        spawnRest++;
    }
    
    // Update the timer value & display
    // Protection against overfilling the timer

    // Update the timer visual

    // Game Over / Time's Up
}

On every loop of the update method, we iterate...
