进入游戏连连第一个场景，如下：

程序分析：

初始化该场景精灵所需的信息、背景/音效及图层UIbool HelloWorld::init()
{if ( !CCLayer::init() ){return false;}this->initData();this->initSounds();this->initUI();return true;初始化场景中船所需的数据
void HelloWorld::initData()
{CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("sailing_boat-hd.plist"); //缓存场景所需图片CCSpriteFrameCache::sharedSpriteFrameCache()->addSpriteFramesWithFile("seagull-hd.plist");boatMoveTime=45.0f;    //时间//船的方向_boatDirection=kLeft;_birdsDirection=birdsLeft;
}初始化游戏背景音乐、音效
void HelloWorld::initSounds()
{SimpleAudioEngine::sharedEngine()->preloadBackgroundMusic("class.mp3");//预加载音频文件SimpleAudioEngine::sharedEngine()->playBackgroundMusic("class.mp3", true); //循环播放音乐}UI界面的初始化
void HelloWorld::initUI()
{CCSprite *bgSprite=NULL;//添加背景图片                    if (wSize.width==1024 && wSize.height==768){bgSprite=CCSprite::create("background_568-hd.png");}else{bgSprite=CCSprite::create("background-hd.png");}bgSprite->setPosition(ccp(wSize.width/2, wSize.height/2));this->addChild(bgSprite, 0);//添加白云（1）cloudSprite=CCSprite::create("background_cloud_1-hd.png");cloudSprite->setAnchorPoint(ccp(0, 0));cloudSprite->setPosition(ccp(0, wSize.height-cloudSprite->getContentSize().height));this->addChild(cloudSprite, 1);//添加白云的影子CCSprite *daoyingloudSprite=CCSprite::create("background_cloud_1-hd.png");daoyingloudSprite->setAnchorPoint(ccp(0, 0));//垂直翻转daoyingloudSprite->setFlipY(true);daoyingloudSprite->setOpacity(40);daoyingloudSprite->setPosition(ccp(wSize.width-cloudSprite->getContentSize().width-40, wSize.height-cloudSprite->getContentSize().height-78*2));this->addChild(daoyingloudSprite, 1);//添加白云2（2）                  cloud2Sprite=CCSprite::create("background_cloud_2-hd.png");cloud2Sprite->setAnchorPoint(ccp(0, 0));cloud2Sprite->setPosition(ccp(cloudSprite->getPosition().x+cloudSprite->getContentSize().width, wSize.height-cloud2Sprite->getContentSize().height));this->addChild(cloud2Sprite, 1);//添加岛CCSprite *landSprite=CCSprite::create("island-hd.png");landSprite->setAnchorPoint(ccp(0, 0));landSprite->setPosition(ccp(wSize.width-landSprite->getContentSize().width-20*2, wSize.height-landSprite->getContentSize().height-47*2));this->addChild(landSprite, 1);//添加岛的倒影CCSprite *daoyinglandSprite=CCSprite::create("island-hd.png");daoyinglandSprite->setAnchorPoint(ccp(0, 0));daoyinglandSprite->setFlipY(true);daoyinglandSprite->setOpacity(40);daoyinglandSprite->setPosition(ccp(wSize.width-landSprite->getContentSize().width-20*2, wSize.height-landSprite->getContentSize().height-78*2));this->addChild(daoyinglandSprite, 1);//添加船boatSprite=CCSprite::createWithSpriteFrameName("sailing_boat1.png");boatSprite->setPosition(ccp(wSize.width-boatSprite->getContentSize().width-50*2,230*2));this->addChild(boatSprite, 1);this->addBoat();//船的动画//添加沙滩CCSprite *shatanSprite=CCSprite::create("beach_adornment-hd.png");shatanSprite->setPosition(ccp(wSize.width/2, shatanSprite->getContentSize().height/2));this->addChild(shatanSprite, 1);//添加海浪if (wSize.width==1136 && wSize.height==640){wavesSprite=CCSprite::create("background_sea1_568-hd.png");}else{wavesSprite=CCSprite::create("background_sea1-hd.png");}wavesSprite->setPosition(ccp(wSize.width/2, 140*2));wavesSprite->setOpacity(0);this->addChild(wavesSprite, 1);this->schedule(schedule_selector(HelloWorld::wavesAnimation), 10);//海浪动画    //添加小鸟birdsSprite=CCSprite::createWithSpriteFrameName("seagull1.png");birdsSprite->setAnchorPoint(ccp(0, 0));birdsSprite->setPosition(ccp(200*2,270*2));birdsSprite->setScale(0.7);this->addChild(birdsSprite, 1);this->schedule(schedule_selector(HelloWorld::birdsselfAnimation), 5);//鸟的定时回调this->birdsselfAnimation2();//鸟飞翔的动画   //添游戏开始菜单CCSprite *playSprite=CCSprite::create("button_play-hd.png");CCSprite *playSprite_s=CCSprite::create("button_play_s-hd.png");CCMenuItemSprite *item=CCMenuItemSprite::create(playSprite, playSprite_s,  this, menu_selector(HelloWorld::playBack));//开始菜单两种状态，并注册回调CCMenu *menu=CCMenu::create(item,NULL);item->setAnchorPoint(ccp(0.5, 0.5));menu->setPosition(ccp(wSize.width/2,110*2));this->addChild(menu, 1);}实现船移动的动画，用array保存船的3种图片状态，并执行动画 , 到两边自动返回 , 就看见船来回的开着：
void HelloWorld::addBoat()
{boatSprite->setFlipX(false);CCArray *array=CCArray::create();for (int i = 1; i < 4; i++){CCString *string=CCString::createWithFormat("sailing_boat%d.png", i);CCSpriteFrame *frame=CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(string->getCString());array->addObject(frame);}CCAnimation *animation=CCAnimation::createWithSpriteFrames(array,0.5);CCAnimate *animate=CCAnimate::create(animation);CCRepeatForever *ac1=CCRepeatForever::create(animate);//无限循环执行boatSprite->runAction(ac1);array->removeAllObjects();//到两边自动返回CCMoveTo *ac2;switch (_boatDirection){case kLeft:ac2=CCMoveTo::create(boatMoveTime, CCPointMake(-boatSprite->getContentSize().width, boatSprite->getPosition().y));_boatDirection=kRight;boatSprite->setFlipX(false);break;case kRight:ac2=CCMoveTo::create(boatMoveTime, CCPointMake(wSize.width, boatSprite->getPosition().y));_boatDirection=kLeft;boatSprite->setFlipX(true);break;default:break;}CCSequence *seq=CCSequence::create(ac2,CCCallFunc::create(this, callfunc_selector(HelloWorld::resetSpritePos)),NULL);boatSprite->runAction(seq);}过10秒来个海浪的动画：
void HelloWorld::wavesAnimation(float dt)
{SimpleAudioEngine::sharedEngine()->playEffect("14.wav");//海浪声CCMoveTo *ac1=CCMoveTo::create(4.0f, CCPointMake(wavesSprite->getPosition().x, 100*2));CCFadeIn *ac2=CCFadeIn::create(4.0f);CCSpawn *spawn=CCSpawn::create(ac1,ac2,NULL);//队列CCSequence *seq=CCSequence::create(spawn,CCCallFunc::create(this, callfunc_selector(HelloWorld::wavesAnimation2)),NULL);wavesSprite->runAction(seq);}鸟的动画,添加鸟叫声，array保存鸟的状态图片，并随机执行动画
void HelloWorld::birdsselfAnimation(float dt)
{SimpleAudioEngine::sharedEngine()->playEffect("15.wav");CCArray *array=CCArray::create();for (int i = 1; i < 4; i++){CCString *string=CCString::createWithFormat("seagull%d.png", i);CCSpriteFrame *frame=CCSpriteFrameCache::sharedSpriteFrameCache()->spriteFrameByName(string->getCString());array->addObject(frame);}CCAnimation *animation=CCAnimation::createWithSpriteFrames(array,0.2);animation->setRestoreOriginalFrame(true);CCAnimate *animate=CCAnimate::create(animation);int times=rand()%5+1;CCRepeat *ac1=CCRepeat::create(animate, times);  //随机间隔飞翔birdsSprite->runAction(ac1);array->removeAllObjects();
}鸟移动的动画 ，飞到了左右边自动往回飞
void HelloWorld::birdsselfAnimation2()
{float yoffset=rand()%40+1;CCPoint birdsPos=CCPointMake(-birdsSprite->getContentSize().width, 270*2+yoffset);CCMoveTo *ac2;switch (_birdsDirection) {case birdsLeft:ac2=CCMoveTo::create(35.0f, CCPointMake(birdsPos.x, birdsPos.y));_birdsDirection=birdsRight;birdsSprite->setFlipX(false);break;case birdsRight:ac2=CCMoveTo::create(35.0f, CCPointMake(wSize.width, 270*2+yoffset));_birdsDirection=birdsLeft;birdsSprite->setFlipX(true);break;default:break;}CCSpawn *spawn=CCSpawn::create(ac2,NULL);CCSequence *seq=CCSequence::create(spawn,CCCallFunc::create(this, callfunc_selector(HelloWorld::resetBirdsSpritePos)),NULL);birdsSprite->runAction(seq);
}开始游戏，点击开始按键，切换下一下场景
void HelloWorld::playBack(CCObject* pSender)
{SimpleAudioEngine::sharedEngine()->stopBackgroundMusic();CCScene *scene=GameLayer::scene();//旋转动画CCDirector::sharedDirector()->replaceScene(CCTransitionRotoZoom::create(1.2f, scene));//CCDirector::sharedDirector()->replaceScene(CCTransitionShrinkGrow::create(1.2f, scene));}
