区别1.去CC

区别2.cc***结构体改变

 
    ? 
   
         2.0

         p1+p2; 
        
         p1-p2 
        
         p1*p2 
        
         p.getLength()

         Color3B::WHITE 
        
         Point::ZERO 
        
         Size:ZERO

区别3.shared***改变(单例机制使用语法)

CCSize winSize = CCDirector::sharedDirector()->getWinSize();

 
         SpriteFrameCache::sharedSpriteFrameCache() 
        

 
         AnimationCache::sharedAnimationCache() 
        

 
         NotificationCenter::sharedNotificationCenter() 
        

…

3.0

 
         Size size = Director::getInstance()->getWinSize(); 
        

 
         SpriteFrameCache::getInstance() 
        

 
         AnimationCache::getInstance() 
        

 
         NotificationCenter::getInstance() 
        

…

区别4.POD类别

         9 
       
      CCPoint

 
         CCSize 
        

 
         CCRect 
        

3.0

 
         Vec2 
        

 
         Size 
        

 
         Rect 
        

区别5.点触事件

         26 
       
         27 
       
         28 
       
         auto dispatcher = Director::getInstance()->getEventDispatcher(); 
        
         auto touchListener = EventListenerTouchOneByOne::create(); 
        
         touchListener->onTouchBegan = CC_CALLBACK_2(FBMainScene::onTouchBegan, 
         this 
         ); 
        
         touchListener->onTouchMoved = CC_CALLBACK_2(FBMainScene::onTouchMoved,monospace!important; font-size:1em!important; min-height:inherit!important">); 
        
         touchListener->onTouchEnded = CC_CALLBACK_2(FBMainScene::onTouchEnded,monospace!important; font-size:1em!important; min-height:inherit!important">); 
        
         dispatcher->addEventListenerWithSceneGraphPriority(touchListener,monospace!important; font-size:1em!important; min-height:inherit!important">); 
        
         bool FBMainScene::onTouchBegan(Touch *touch,Event *pEvent){ 
        
         CCLOG( 
         "onTouchBegan" 
         ); 
        
         Point point =  
         ->convertToWorldSpace( 
         ->convertTouchToNodeSpace(touch)); 
        
         return 
          true 
         ; 
        
         } 
        
         void 
          FBMainScene::onTouchMoved(Touch *touch,Event *pEvent){ 
        
         "onTouchMoved" 
         ); 
        
         } 
        
          FBMainScene::onTouchEnded(Touch *touch,Event *pEvent){ 
        
         "onTouchEnded" 
         ); 
        
         } 
        
         //获得触点的方法也发生了改变： 
        
         ->convertTouchToNodeSpace(touch)); 
        
         //dispatcher控制方法： 
        
         dispatcher->addEventListener… 
        
         dispatcher->removeEventListener(listener); 
        
         dispatcher->removeAllListeners();

区别6.回调函数

CC_CALLBACK_0 CC_CALLBACK_1 CC_CALLBACK_2 CC_CALLBACK_3回调函数，分别携带不同的参数，方便

         10 
       
      CCMenuItemFont *item = CCMenuItemFont::create( 
         "返回上个场景",menu_selector(GameScene::backScene));
 
         3.0 
        
         MenuItemFont *item = MenuItemLabel::create( 
         )); 
        
         // new callbacks based on C++11 
        
         #define CC_CALLBACK_0(__selector__,__target__,) std::bind(&__selector__,##__VA_ARGS__) 
        
         #define CC_CALLBACK_1(__selector__,std::placeholders::_1,##__VA_ARGS__) 
        
         #define CC_CALLBACK_2(__selector__,std::placeholders::_2,##__VA_ARGS__) 
        
         #define CC_CALLBACK_3(__selector__,std::placeholders::_3 ##__VA_ARGS__)

区别7.CallFunc使用(使用"Function"对象)

 
      ? 
     
           CallFunc::create([&](){ 
          
           Sprite *sprite = Sprite::create( 
           "s" 
           ); 
          
           this 
           ->addChild(sprite); 
          
           });

区别8.使用clone代替copy

           4 
         
           5 
         
           6 
         
           2.0 
          
           CCMoveBy *action = (CCMoveBy*) move->copy(); 
          
           action->autorelease(); 
          
           3.0 
          
           action = move->clone(); 
          
           不需要autorelease，在clone已经实现。

区别9.Physics Integration 物理引擎

           2 
         
  
        暂无使用，box2d 在  
           3.0中可以延续使用

 
           在 
           的Physics中需要定义 PhysicsWorld,PhysicsBody,PhysicsShape,PhysicsJoint 等，于box2d相仿，使用前需要定义CC_USE_PHYSICS

区别10.容器
