上一部分介绍到片头动画介绍后进入到菜单场景，场景效果如图

MenuScene.h头文件如下：

class MenuScene : public Layercolor  {public:    static Scene* createScene();      virtual bool init();             CREATE_FUNC(MenuScene);private:	Size visibleSize; //窗口尺寸	LabelTTF* settingsGameTTF; //场景文字	voID menutouchDown (Object* pSender,Control::EventType event);// Menu点击回调方法	voID addBackgroundSprite(); //添加场景背景方法	voID addMenuSprites();//添加Menu方法	 };#endif

MenuScene.cpp部分代码如下：

bool MenuScene::init(){	if ( !Layercolor::initWithcolor(color4B(255,255,255)) )    {        return false;    }	visibleSize = Director::getInstance()->getVisibleSize();                Vec2 origin = Director::getInstance()->getVisibleOrigin();	addBackgroundSprite();//添加场景背景方法	addMenuSprites(); //添加Menu方法    return true;}

voID MenuScene::addBackgroundSprite(){                 //添加大富翁背景图片，居中显示	Sprite* menuSpritelogo= Sprite::create(MENU_logo);	menuSpritelogo->setposition(ccp(visibleSize.wIDth/2,visibleSize.height));	menuSpritelogo->setAnchorPoint(ccp(0.5,1));	menuSpritelogo->setScale(0.6f);	addChild(menuSpritelogo);             //添加左边彩虹图片	Sprite* rainBowSprite= Sprite::create(RAINBOW);	rainBowSprite->setposition(ccp(5,visibleSize.height-20));	rainBowSprite->setAnchorPoint(ccp(0,1));	rainBowSprite->setScale(0.3f);	addChild(rainBowSprite);               //让彩虹图片左右移动	MoveBy* rainBowMove = MoveBy::create(1,ccp(8,0));	MoveBy* rainBowMoveReverse = rainBowMove->reverse();	Sequence* rainBowAction = Sequence::create(rainBowMove,rainBowMoveReverse,NulL);	rainBowSprite->runAction(RepeatForever::create(rainBowAction));}

voID MenuScene:: addMenuSprites(){              //添加单机游戏Menu  	Scale9Sprite* btnnormal = Scale9Sprite::create(norMAL_MENU); //设置菜单normal图片	Scale9Sprite* btnPress = Scale9Sprite::create(PRESS_MENU);// 设置菜单press图片	LabelTTF* singleGameTTF = LabelTTF::create(SINGLE_GAME,Font_MENU,Btn_FontSize);//创建菜单所需的Label对象	Controlbutton* singleGameBtn = Controlbutton::create(singleGameTTF,btnnormal);//创建controlbutton	singleGameBtn->setBackgroundSpriteForState(btnPress,Control::State::SELECTED);//添加singlebutton菜单的press效果图片	singleGameBtn->setposition(ccp(visibleSize.wIDth/2,visibleSize.height-200));//设置位置	singleGameBtn->setPreferredSize(Size(Btn_WIDth,Btn_Height));//设置大小	singleGameBtn->addTargetWithActionForControlEvents(this,cccontrol_selector(MenuScene::menutouchDown),Control::EventType::touch_DOWN);//设置点击回调方法	singleGameBtn->setTag(Btn_Single_Game_TAG);//设置Tag	addChild(singleGameBtn);//添加menu             //其他menu添加方法，同上类似，不再重复.	………………………..               //settings菜单不大一样，该菜单点击都有打开或关闭音效。	Scale9Sprite* btnnormal3 = Scale9Sprite::create(norMAL_MENU);	Scale9Sprite* btnPress3 = Scale9Sprite::create(PRESS_MENU);	bool music_on = UserDefault::getInstance()->getBoolForKey(MUSIC_ON_KEY,true);//获取音效设置LabelTTF* settingsGameTTF;//如果音效开，则menu显示on，如果关，显示off	if(music_on)	{		settingsGameTTF = LabelTTF::create(MUSIC_ON,Btn_FontSize);	}else	{                              settingsGameTTF = LabelTTF::create(MUSIC_OFF,Btn_FontSize);	}		Controlbutton* settingsGameBtn = Controlbutton::create(settingsGameTTF,btnnormal3);	settingsGameBtn->setBackgroundSpriteForState(btnPress3,Control::State::SELECTED);	settingsGameBtn->setposition(ccp(visibleSize.wIDth/2,visibleSize.height-320));	settingsGameBtn->setPreferredSize(Size(Btn_WIDth,Btn_Height));	settingsGameBtn->addTargetWithActionForControlEvents(this,cccontrol_selector(MenuScene:: menutouchDown),Control::EventType::touch_DOWN);//添加setting回调	settingsGameBtn->setTag(Btn_Music_TAG);	addChild(settingsGameBtn);                ………………………}

Menu点击的回调方法，根据点击对象tag调用相应方法，此处主要的是case语句需要添加 { } 括号，否则编译报错

voID MenuScene:: menutouchDown(Object* pSender,Control::EventType event){	log("single touched");	Controlbutton* button = (Controlbutton*)pSender;	int tag = button->getTag();switch(tag)	{		case Btn_Single_Game_TAG:			{				log("single game");				//Director::getInstance()->pushScene(MapChooseScene::createScene());			}		case Btn_Multi_Game_TAG:			{				log("multi game");				break;			}		case Btn_Music_TAG:			{				bool music_on = UserDefault::getInstance()->getBoolForKey(MUSIC_ON_KEY,true);				if(music_on)				{					UserDefault::getInstance()->setBoolForKey(MUSIC_ON_KEY,false);//设置音效关					button->setTitleForState(MUSIC_OFF,Control::State::norMAL);//让menu文字显示off				}else				{					UserDefault::getInstance()->setBoolForKey(MUSIC_ON_KEY,true);//设置音效开					button->setTitleForState(MUSIC_ON,Control::State::norMAL);// 让menu文字显示on				}						break;			}		case Btn_Quit_Game_TAG:			{				log("quit game");				//popupLayer();d出退出对话框，代码较多，后续编写				break;			}	   default:  		   break;	}

代码比较简单
