1、以CC开头的类从此去掉CC，如：
| v2.1 | v3.0 | | CCSprite | Sprite | | CCNode | Node | | CCDirector | Director | | etc... |
举个例子，创建一个精灵的方式：
v2.0 CCSprite* sp = CCSprite::create(); v3.0 auto sp = Sprite::create();
2、clone() 替代 copy()
3、Director的单例换成getInstance() 和 destroyInstance();
| v2.1 | v3.0 | | CCDirector->sharedDirector() | Director->getInstance() | | CCDirector->endDirector() | Director->destroyInstance() | | etc... |
4、新的触摸机制，先贴一段代码给大家看看，可能是下一篇或者下下篇我会详细讲下新的触摸机制的。
auto sprite = Sprite::create("file.png");
...
auto listener = EventListenerTouchOneByOne::create();
listener->setSwallowTouch(true);
listener->onTouchBegan = [](Touch* touch,Event* event) { do_some_thing(); return true; };
listener->onTouchMoved = [](Touch* touch,Event* event) { do_some_thing(); };
listener->onTouchEnded = [](Touch* touch,Event* event) { do_some_thing(); };
listener->onTouchCancelled = [](Touch* touch,Event* event) { do_some_thing(); };
// The priority of the touch listener is based on the draw order of sprite
EventDispatcher::getInstance()->addEventListenerWithSceneGraPHPriority(listener,sprite);
// Or the priority of the touch listener is a fixed value
EventDispatcher::getInstance()->addEventListenerWithFixedPriority(listener,100); // 100 is a fixed value

一些全局的定义：
// in v2.1 ccColor3B color3B = ccc3(0,0); ccc3BEqual(color3B,ccc3(1,1,1)); ccColor4B color4B = ccc4(0,0); ccColor4F color4F = ccc4f(0,0); color4F = ccc4FFromccc3B(color3B); color4F = ccc4FFromccc4B(color4B); ccc4FEqual(color4F,ccc4F(1,1)); color4B = ccc4BFromccc4F(color4F); color3B = ccWHITE; // in v3.0 Color3B color3B = Color3B(0,0); color3B.equals(Color3B(1,1)); Color4B color4B = Color4B(0,0); Color4F color4F = Color4F(0,0); color4F = Color4F(color3B); color4F = Color4F(color4B); color4F.equals(Color4F(1,1)); color4B = Color4B(color4F); color3B = Color3B::WHITE;
