PrefabUtility.UnpackAllInstancesOfPrefab

参数

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.

    {
        var prefabAssetRoot = AssetDatabase.LoadMainAssetAtPath(prefabPath) as GameObject;
        if (prefabAssetRoot != null)
        {
            PrefabUtility.UnpackAllInstancesOfPrefab(prefabAssetRoot, PrefabUnpackMode.OutermostRoot, InteractionMode.UserAction);
        }
    }
