cocos2dx-3.0(10)------3.0的一些基本改变特性

～～～～我的生活，我的点点滴滴！！                  

本篇转到至star的，写的很好，可以当个基本的表来查看 链接http://blog.csdn.net/star530/article/details/18052953

下面我们一起来看看改变。

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(), 这个我用的不多，所以也就不多交代了；

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  

5、还有一些杂七杂八的东西，本人理解的不透，也就不发出来献丑了，最后将CCType.h 里的一些变动贴出来，让我们愉快的结束这篇博文。

| v2.1 struct names | v3.0 struct names |
| ccColor3B         | Color3B |
| ccColor4B         | Color4B |
| ccColor4F         | Color4F |
| ccVertex2F        | Vertex2F |
| ccVertex3F        | Vertex3F |
| ccTex2F           | Tex2F |
| ccPointSprite     | PointSprite |
| ccQuad2           | Quad2 |
| ccQuad3           | Quad3 |
| ccV2F_C4B_T2F     | V2F_C4B_T2F |
| ccV2F_C4F_T2F     | V2F_C4F_T2F |
| ccV3F_C4B_T2F     | V3F_C4B_T2F |
| ccV2F_C4B_T2F_Triangle | V2F_C4B_T2F_Triangle |
| ccV2F_C4B_T2F_Quad | V2F_C4B_T2F_Quad |
| ccV3F_C4B_T2F_Quad | V3F_C4B_T2F_Quad |
| ccV2F_C4F_T2F_Quad | V2F_C4F_T2F_Quad |
| ccBlendFunc       | BlendFunc |
| ccT2F_Quad        | T2F_Quad |
| ccAnimationFrameData | AnimationFrameData |

一些全局的定义：

// in v2.1
ccColor3B color3B = ccc3(0, 0, 0);
ccc3BEqual(color3B, ccc3(1, 1, 1));
ccColor4B color4B = ccc4(0, 0, 0, 0);
ccColor4F color4F = ccc4f(0, 0, 0, 0);
color4F = ccc4FFromccc3B(color3B);
color4F = ccc4FFromccc4B(color4B);
ccc4FEqual(color4F, ccc4F(1, 1, 1, 1));
color4B = ccc4BFromccc4F(color4F);

color3B = ccWHITE;

// in v3.0
Color3B color3B = Color3B(0, 0, 0);
color3B.equals(Color3B(1, 1, 1));
Color4B color4B = Color4B(0, 0, 0, 0);
Color4F color4F = Color4F(0, 0, 0, 0);
color4F = Color4F(color3B);
color4F = Color4F(color4B);
color4F.equals(Color4F(1, 1, 1, 1));
color4B = Color4B(color4F);

color3B = Color3B::WHITE;
