根據步驟創建了ABC 三個場景，依次綁定了ABC三個C#代碼文件，然後運行報錯
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)解決辦法： File->Build Settings->Add Open Scene
把三個場景都添加了，再運行就OK了
