// This function will be called when the app is inactive. When comes a phone call,it’s be invoked too

}
这一段代码中我已经#include "GameScene.h"了为什么还会出现
error C2653: “GameScene”: 不是类或命名空间名称
error C3861: “createScene”: 找不到标识符
的错误啊。。。
求大神解答下,困扰两天了。。。T T。。。。

参照helloworld,复制一下,
改一下某些代码试试。

请问flappy bird代码里怎么控制鸟数量啊。。。比如我要显示好多鸟

// create a scene. it’s an autorelease object
auto scene = GameScene::createScene();
因为你这儿用到了GameScene
