Definition

public void OnDisable()

Remarks

OnDisable
is called in the following scenarios: * On loading a scene in the Hierarchy window, for any ScriptableObject that is currently loaded in memory but is not referenced in that scene. * On invocation of Resources.UnloadUnusedAssets for any ScriptableObject that was previously deselected in the Project window. * On domain reload, for all ScriptableObjects loaded in memory. Subsequently 
OnEnable
is called for these objects when they are recreated. 
OnDisable
cannot be a coroutine.
