scene reload question

Are there any downsides to disabling scene reload? I couldn’t see any in the user manual.

I’ve mentioned some sideeffects in the post here .

Important differences due to skipping Scene Reload
Avoiding Scene Reload is much more complex to implement and align with the normal loading path, but should have minimal side effects. However, due to its tight connection to Domain Reload, there are a couple of important differences:

  • ScriptableObject, MonoBehaviour fields which are not serialized into the build ([NonSerialized], private or internal) keep their values - as existing objects are not recreated and constructors are not called.
    Watch out for null private and internal fields of array/List type - they are converted to an empty array/List object during Domain Reload and stay non null for game scripts.
  • ExecuteInEditMode/ExecuteAlways scripts are not destroyed/awaken - no OnDestroy/Awake calls for those.
    Watch out for Awake/OnEnable methods which check EditorApplication.isPlaying property - Awake is not called and OnEnable is called only when EditorApplication.isPlaying is already true on Play Mode change.

We are updating the manual to reflect the most recent information.
