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

パラメーター

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

説明

Adds this removed GameObject back on the Prefab instance.

After the revert action the GameObject will once again exist on the Prefab instance.

The GameObject's components and children will also exist again, unless they had previously been removed.

Note that added GameObjects and added component overrides, which were in the hierarchy of the reverted GameObject before it was removed, will not be restored.
