Determines the flags for the Enter Play Mode Options in the Unity Editor.
| None | This makes Unity reload the .NET Application Domain and entire Scene when entering Play Mode. |
| DisableDomainReload | When Domain Reload is disabled, scripts are not reloaded when entering Play Mode. This makes it quicker to switch to Play Mode, because there's no need to destroy, create and reload the .NET Application Domain. |
| DisableSceneReload | When Scene Reload is disabled, Unity resets the Scene state and emulates all of the required post-processor calls when entering Play Mode, instead of reloading the whole Scene. This makes it quicker to switch to Play Mode, because there's no need to destroy, create and awaken all the Scene objects, and serialize and deserialize the Scene from disk. |
| DisableSceneBackupUnlessDirty | When enabled, this reduces the time taken to enter play mode by only backing up scenes marked dirty, but can result in data loss in certain situations. |
