1.淡入淡出动画

     最近在做一个项目，分享给大家一个不错的例子，我们可以用这个模板去设计我们的游戏开机动画哦。

2.效果如下

3.例子如下

          // create a scene. it's an autorelease object
          auto scene = LogoScene::createScene();
          // run
           director->runWithScene(scene);
          return true;
   
  

//LogoScene类
 

      #include "LogoScene.h"
      #include "AppDelegate.h"
      USING_NS_CC;
      Scene* LogoScene::createScene()
      {
         auto scene = Scene::create();
         auto layer = LogoScene::create();
     	auto s = Director::getInstance()->getVisibleSize();
     	//开机第一张图片，选择自己喜欢的图片哦
      	Sprite* pSprite = Sprite::create("logo_telecom.png");
     	if (pSprite)
      	{
     		//屏幕的位置
      		pSprite->setPosition(s.width/2,s.height/2);
     		//99号节点
      		layer->addChild(pSprite, 0, 99);
      	}
      	scene->addChild(layer);
         return scene;
      }
      // on "init" you need to initialize your instance
      bool LogoScene::init()
      {
         if ( !Layer::init() )
          {
             return false;
          }
     	auto pCCLayerColor = LayerColor::create(Color4B(255, 255, 255, 255));
     	addChild(pCCLayerColor);
     	scheduleOnce(schedule_selector(LogoScene::logoshowCallback), 1.0f);
         return true;
      }
      void LogoScene::logoshowCallback(float temp)
      {
      	{
     		//背景图淡入消去
      		Sprite* pSprite = (Sprite*)(getChildByTag(99));
      		FadeOut* pAction = FadeOut::create(0.625f);
      		pSprite->runAction(pAction);
      	}
     	auto pCCLayerColor = LayerColor::create(Color4B(255, 255, 255, 255));
      	{
     		//延迟纯白色背景加载0.625秒动作
     		addChild(pCCLayerColor);
      		pCCLayerColor->setOpacity(0);
      		DelayTime* pAction1 = DelayTime::create(0.625f);
      		FadeIn* pAction2 = FadeIn::create(0.625f);
     		//DelayTime* pAction3 = DelayTime::create(1.0f);
      		pCCLayerColor->runAction(Sequence::create(pAction1, pAction2, NULL));
      	}
     	auto s = Director::getInstance()->getVisibleSize();
     	//logo的图片
      	Sprite* pSprite = Sprite::create("gamedo.png");
      	{
      		pSprite->setPosition(s.width / 2, s.height / 2);
      		pCCLayerColor->addChild(pSprite);
      		pSprite->setOpacity(0);
      		DelayTime* pAction1 = DelayTime::create(0.625f);
      		FadeIn* pAction2 = CCFadeIn::create(0.625f);
     		//DelayTime* pAction3 = DelayTime::create(1.0f);
      		pSprite->runAction(Sequence::create(pAction1, pAction2, NULL));
      	}
     	scheduleOnce(schedule_selector(LogoScene::logoshowOver), 2.00f);
      }
      void LogoScene::logoshowOver(float temp)
      {
     	//场景迁移 ,这里我们以后可以单独做一个 控制场景迁移的类
     	//CCDirector::sharedDirector()->replaceScene(MainScene::Create());
      }
