public static void ApplyRemovedGameObject (GameObject gameObjectInInstance, GameObject assetGameObject, InteractionMode action);

파라미터

gameObjectInInstance A GameObject in the Prefab instance containing the removed GameObject.
assetGameObject The GameObject in the Prefab Asset corresponding to the removed GameObject on the instance.
action The interaction mode for this action.

설명

Removes the GameObject from the source Prefab Asset.

When a GameObject is removed from a Prefab instance, that modification is a type of Instance Override. The act of applying the change (the removal of the GameObject) to the Prefab means the GameObject is removed from the Prefab Asset itself, along with its components and GameObject children, and is no longer an override on the Prefab instance.

When applying a removed GameObject to a Prefab Asset, you must supply the asset path as a parameter. This is because there are some situations where there are multiple possible targets to apply the change to. For example, if the GameObject was removed from a GameObject that is part of a nested Prefab instance, you may have the choice of applying the change to the inner nested Prefab Asset, or to the outer root Prefab Asset. Therefore, by specifying the asset path, you make it clear to Unity which Prefab Asset the change must be applied to. It mirrors the functionality in the editor, described in the user manual here.

You can read more in the user manual about the choice of apply targets.
