(十三) 分数场景
最后更新于：2022-04-01 16:12:34
分数场景要用到TableView，这个之前也没用过，主要参考网上的代码。cocos2d-x的功能十分强大，以后还有好多东西要学啊！
分数场景类的.h文件中的内容

void scrollViewDidScroll(ScrollView *){};
void scrollViewDidZoom(ScrollView *){};
//对返回键的响应
void onKeyReleased(EventKeyboard::KeyCode keyCode, Event * pEvent);

好了，这个游戏到这里就已经完成啦！再有的就是移植到其它平台了。我是将这个游戏移植到了Android平台。
