根据步骤创建了ABC 三个场景，依次绑定了ABC三个C#代码文件，然后运行报错

Scene 'B' couldn't be loaded because it has not been added to the build settings or the AssetBundle has not been loaded.
To add a scene to the build settings use the menu File->Build Settings...
UnityEngine.Application:LoadLevel(String)
A:Start() (at Assets/New Folder/A.cs:12)

解决办法： File->Build Settings->Add Open Scene

把三个场景都添加了，再运行就OK了
