cocos2d-x 3.0sprite轮换

主要是看了偶尔e网事童鞋提出的一篇，主要是改下代码风格，coco2d-x设计木有风格，是copy的，所以努力走自己的风格。

就是sence里面加layer，运行sence渲染layer。

最讨厌那么多static函数了，这根objected programming有毛关系？

果断修改：

bool AppDelegate::applicationDidFinishLaunching() {    // initialize director    auto director = Director::getInstance();    auto eglView = EGLView::getInstance();    director->setOpenGLView(eglView);    // turn on display FPS    director->setDisplayStats(true);    // set FPS. the default value is 1.0/60 if you don't call this    director->setAnimationInterval(1.0 / 60);    // create a scene. it's an autorelease object    auto scene = new GameSence();    // run    director->runWithScene(scene);    return true;}

然后sence类很简单，很清爽：

class GameSence : public cocos2d::Scene{public:GameSence();private:GameLayer* m_pGameLayer;};GameSence::GameSence(){m_pGameLayer = new GameLayer;addChild(m_pGameLayer);}

GameLayer也很简单：

class GameLayer : public cocos2d::Layer{public:GameLayer();void backGroupMove(float dt);private:cocos2d::Sprite* m_pBackground1;cocos2d::Sprite* m_pBackground2;};GameLayer::GameLayer(){cocos2d::Layer::init();auto spriteFrameCache = cocos2d::SpriteFrameCache::sharedSpriteFrameCache(); spriteFrameCache->addSpriteFramesWithFile("shoot_background.plist");m_pBackground1= Sprite::createWithSpriteFrame(spriteFrameCache->getSpriteFrameByName("background.png"));m_pBackground1->setPosition(ccp(0,0));m_pBackground1->setAnchorPoint(ccp(0,0));addChild(m_pBackground1);m_pBackground2= Sprite::createWithSpriteFrame(spriteFrameCache->getSpriteFrameByName("background.png"));m_pBackground2->setPosition(ccp(0,m_pBackground2->getContentSize().height-5));m_pBackground2->setAnchorPoint(ccp(0,0));addChild(m_pBackground2);schedule(schedule_selector(GameLayer::backGroupMove), 0.01f);}void GameLayer::backGroupMove(float dt){m_pBackground1->setPositionY(m_pBackground1->getPositionY()-2);m_pBackground2->setPositionY(m_pBackground1->getPositionY() + m_pBackground1->getContentSize().height -2);if (m_pBackground2->getPositionY() == 0){m_pBackground1->setPositionY(0);}}

然后显示就是打飞机背景一直在动，飞机飞啊，飞到啦啦啦！
