cocos2dx 3.0一些变化

2019-05-18 Cocos2d-x 前端之家

前端之家收集整理的这篇文章主要介绍了cocos2dx 3.0一些变化，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

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：

[cpp]view plaincopy 
   
 v2.0
 CCSprite*sp=CCSprite::create();
 
 
 v3.0
 autosp=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。

autosprite=Sprite::create("file.png");

...
autolistener=EventListenerTouchOneByOne::create();
listener->setSwallowTouch(true);
listener->onTouchBegan=[](Touch*touch,Event*event){do_some_thing();returntrue;};
listener->onTouchMoved=[](Touch*touch,Event*event){do_some_thing();};
listener->onTouchEnded=[](Touch*touch,Event*event){do_some_thing();};
listener->onTouchCancelled=[](Touch*touch,108); list-style:decimal-leading-zero outside; color:inherit; line-height:18px; margin:0px!important; padding:0px 3px 0px 10px!important"> //Thepriorityofthetouchlistenerisbasedonthedraworderofsprite
EventDispatcher::getInstance()->addEventListenerWithSceneGraPHPriority(listener,sprite);
//Orthepriorityofthetouchlistenerisafixedvalue
EventDispatcher::getInstance()->addEventListenerWithFixedPriority(listener,100);//100isafixedvalue

一些全局的定义：

// in v2.1
ccColor3B color3B = ccc3(0, 0);
ccc3BEqual(color3B, ccc3(1,153)">1));
ccColor4B color4B = ccc4(0);
ccColor4F color4F = ccc4f(0);
color4F = ccc4FFromccc3B(color3B);
color4F = ccc4FFromccc4B(color4B);
ccc4FEqual(color4F, ccc4F(1));
color4B = ccc4BFromccc4F(color4F);

color3B = ccWHITE;

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

color3B = Color3B::WHITE;

继续...
