游戏结束的时候，要显示分数，还要能够选择是返回主场景还是退出游戏
~~~
// 退出游戏
void menuCloseCallback(cocos2d::Ref* pSender);
// 返回主界面
void menuMainCallback(cocos2d::Ref* pSender);
~~~
实现该功能的代码如下
~~~
bool GameOver::init()
{
//////////////////////////////
// 1. super init first
if (!Layer::init())
{
return false;
}
bool bRect = false;
//背景音乐
