Cocos2dx 3.0 過渡篇（一） 初體驗

方法/步驟

1、以CC開頭的類從此去掉CC，如：

v2.1 v3.0

CCSprite Sprite

CCNode Node

CCDirector Director

etc...

舉個例子，創建一個精靈的方式：

v2.0

CCSprite* sp = CCSprite::create();

v3.0

auto sp = Sprite::create();

2、clone() 替代 copy(), 這個我用的不多，所以也就不多交代了；

3、Director的單例換成getInstance() 和 destroyInstance();

v2.1 v3.0

CCDirector->sharedDirector() Director->getInstance()

CCDirector->endDirector() Director->destroyInstance()

etc...

4、新的觸摸機制，先貼一段代碼給大家看看，可能是下一篇或者下下篇我會詳細講下新的觸摸機制的。

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

5、還有一些雜七雜八的東西，本人理解的不透，也就不發出來獻醜了，最後將CCType.h 裡的一些變動貼出來，讓我們愉快的結束這篇經驗。

一些全局的定義：
