PrefabUtility.UnpackAllInstancesOfPrefab

切换到手册
public static void UnpackAllInstancesOfPrefab (GameObject prefabRoot, PrefabUnpackMode unpackMode, InteractionMode action);

参数

prefabRoot The root GameObject of a Prefab Asset used to find all Prefab instances in open scenes that should be unpacked.
unpackMode 解压缩最外层根,还是完全解压缩。
action 用于此操作的交互模式。

描述

Unpacks all instances of a given Prefab Asset root GameObject in all open scenes so that all instances are replaced with the contents of the Prefab Asset while retaining all override values.

The Prefab instances will not be unpacked in closed scenes. This function uses PrefabUtility.FindAllInstancesOfPrefab to determine which instances to unpack and calls PrefabUtility.UnpackPrefabInstance for each instance.

Unpacking throws an ArgumentException if the given object is not the root GameObject of a Prefab Asset.
