每日一曲【程序猿做久了,你是否忽略了身边的人?】

 

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();

| v2.1                                                      | v3.0                                          |
| CCDirector->sharedDirector() | Director->getInstance() |
| 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;
