설명

Replace the Prefab Asset for a Prefab instance that exists in a Scene or for a nested Prefab instance inside another Prefab.

This function will keep the Prefab instance root position, rotation and scale in the Scene but merge the contents from the new Prefab Asset while, by default, maintaining as many overrides and references as possible by using name based matching. Note that the root GameObject and its components will always reuse these objects regardless of the ObjectMatchMode, so references to these objects will always survive a replacement. Use ObjectMatchMode.ByHierarchy which will retain references if GameObjects and Components are matched up using their full GameObject hierarchy path so ensure all siblings have unique names. When using ObjectMatchMode.ByName an object match is only performed if the name match is unique. It is therefore recommended that the Prefab instance and Prefab Asset only have unique names in the hierarchy of GameObjects. Matching cannot be done for GameObjects with duplicate names.

No property overrides are deleted from the serialized state of the Prefab instance so replacing back and forth between different Prefab Assets is a non-destructive action for property overrides. When the final Prefab instance is decided upon then any unused overrides can be cleaned up from either Hierarchy or Overrides window. Added Components are preserved if a name match exists, otherwise the added Component is deleted. Added GameObjects are preserved by adding them to the root of the new instance if no name match was found for its parent GameObject. Since an added GameObject can have a full hierarchy under it, we leave it to you to decide whether it makes sense to delete the object if it proves redundant on the new instance. This can be done from either the Hierarchy or Overrides window. For explict control over which overrides should be cleared use the PrefabReplacingSettings.prefabOverridesOptions flags found in the PrefabReplacingSettings.
