| componentOrGameObject | The object to check. Must be a component or GameObject. |
bool True if the object is part of a Prefab that cannot be edited.
Is this object part of a Prefab that cannot be edited?
For an object on a Prefab Asset, the asset itself is checked. For an object on a Prefab instance, its corresponding asset is checked.
Examples of immutable Prefabs are Model Prefab and Prefabs in read-only folders.
For Prefab contents loaded in Prefab Mode, this method will not check the Prefab Asset the loaded contents are loaded from, since these Prefab contents are loaded into a preview scene and are not part of an Asset while being edited in Prefab Mode. This means that for Prefab contents in Prefab Mode, the method will return true for instances of immutable Prefabs, but not for GameObjects or components that are not part of a Prefab instance.
