分數場景要用到TableView，這個之前也沒用過，主要參考網上的代碼。cocos2d-x的功能十分強大，以后還有好多東西要學啊！
分數場景類的.h文件中的內容
~~~
class ScoreScene : public Layer, public TableViewDataSource, public TableViewDelegate
{
public:
ScoreScene();
~ScoreScene();
public:
static Scene * createScene();
bool init();
CREATE_FUNC(ScoreScene);
public:
void tableCellTouched(TableView *table, TableViewCell * cell){};
TableViewCell * tableCellAtIndex(TableView * table, ssize_t index);
Size tableCellSizeForIndex(TableView * table, ssize_t index);
ssize_t numberOfCellsInTableView(TableView * table);
void scrollViewDidScroll(ScrollView *){};
void scrollViewDidZoom(ScrollView *){};
//對返回鍵的響應
void onKeyReleased(EventKeyboard::KeyCode keyCode, Event * pEvent);

好了，這個游戲到這里就已經完成啦！再有的就是移植到其它平臺了。我是將這個游戲移植到了Android平臺。
