Unity Editor: check if OnDestroy() method is called because the scene is closing

Question

There are 2 cases when OnDestroy() is triggered in the Editor (the class should be marked with [ExecuteInEditMode] attribute):

1. When the scene is closing and all objects are destroyed.
2. When an object is deleted from the scene.

Is it possible to differentiate these two cases within OnDestroy()? I tried to subscribe to EditorSceneManager.sceneClosing to set the flag and then use it in OnDestroy() but this event didn't work. Are there any other options?

Answer 1

A bit of an old question but it's the first result in Google so I thought I might share my approach.

void OnDestroy()
{
    if(gameObject.scene.isLoaded) //Was Deleted
    {

    }
    else //Was Cleaned Up on Scene Closure
    {

    }
}
