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.

Touching moles


By this point, we have moles that can be spawned, animated, and reset. What about the real fun, the mole thumping? For that, we look at the MXMole.m file, where all of the mole touch handling is coded:

Filename: MXMole.m

#import "MXMole.h"

@implementation MXMole

@synthesize parentHill;
@synthesize moleSprite;
@synthesize moleGroundY;
@synthesize moleState = _moleState;
@synthesize isSpecial;

-(id) init {
    if(self = [super init]) {
            self.moleState = kMoleDead;
            [[[CCDirector sharedDirector] touchDispatcher]
                    addTargetedDelegate:self priority:0
                    swallowsTouches:NO];
    }
  return self;  
}

- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
    CGPoint location = [touch locationInView:[touch view]];
    CGPoint convLoc = [[CCDirector sharedDirector]
                       convertToGL:location];
    
    if (self.moleState == kMoleDead) {
        return NO;
    } else if (self.moleSprite.position...
