程序源码：

bool HelloWorld::init()
{if ( !CCLayer::init() ){return false;}CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();CCMenuItemImage *pCloseItem = CCMenuItemImage::create("CloseNormal.png","CloseSelected.png",this,menu_selector(HelloWorld::menuCloseCallback));pCloseItem->setPosition(ccp(origin.x + visibleSize.width - pCloseItem->getContentSize().width/2 ,origin.y + pCloseItem->getContentSize().height/2));CCMenu* pMenu = CCMenu::create(pCloseItem, NULL);pMenu->setPosition(CCPointZero);this->addChild(pMenu, 1);CCSprite *flare = CCSprite::create("flare.jpg");flare->setPosition(ccp(visibleSize.width/2, visibleSize.height/2));this->addChild(flare);flare->setOpacity(0);// 设置初始透明度flare->setRotation(-120);// 设置初始角度flare->setScale(0.2f);// 设置初始缩小倍// 由不透明到透明渐变CCActionInterval *opacityAnim = CCFadeTo::create(0.5f, 255);CCActionInterval *opacDim = CCFadeTo::create(1.0f, 0);// 0.7s放大1.2倍, 放大动作减速CCActionInterval *bigAnim = CCScaleBy::create(0.7f, 1.2f, 1.2f);CCEaseSineOut *biggerEase = CCEaseSineOut::create(bigAnim);//0.5s移动新位置，移动动作减速CCActionInterval *moveAnim = CCMoveBy::create(0.5f, ccp(328, 0));CCEaseSineOut *moveEase = CCEaseSineOut::create(moveAnim);// 角度旋转90',角度旋转速度，指数减速CCActionInterval *roteAnim = CCRotateBy::create(2.5f, 90); CCEaseExponentialOut * rotateEase = CCEaseExponentialOut::create(roteAnim);// 放大到原大小CCScaleTo *bigger = CCScaleTo::create(0.5f, 1);// 执行动画和回调函数切换GameLayer场景flare->runAction(CCSequence::create(opacityAnim, biggerEase, opacDim,  NULL));//初始化sprite设置完成后，显示sprite,然后放大0.7s持续放大1.2倍，再设置为透明flare->runAction(moveEase);//0.5s持续减速移动到新的位置flare->runAction(rotateEase);//指数减速2.5s持续旋转90'flare->runAction(bigger);//最后恢复原大小return true;
