在运行的时候遇到了如下错误
错误 5 error LNK2019: 无法解析的外部符号 “public: void __thiscall BackgroundLayer::Start(class cocos2d::Ref *)” (?Start@BackgroundLayer@@QAEXPAVRef@cocos2d@@@Z)，该符号在函数 “public: virtual bool __thiscall BackgroundLayer::init(void)” (?init@BackgroundLayer@@UAE_NXZ) 中被引用 D:\project\test3\proj.win32\BackgroundLayer.obj test3
错误 6 error LNK1120: 1 个无法解析的外部命令 D:\project\test3\proj.win32\Debug.win32\test3.exe test3
