Level '01' (-1) couldn't be loaded because it has not been added to the build settings. To add a level to the build settings use the menu File->Build Settings... UnityEngine.Application:LoadLevel(String) restart:OnGUI() (at Assets/scripts/restart.js:12)
具体应该怎么在build settings中add a level

在file`buildsetting把所有需要加载的场景都放进去

楼上正解
