Unity中删除预制体的子物体-Toy模板网

这篇具有很好参考价值的文章主要介绍了Unity中删除预制体的子物体。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

Unity中要删除预制体中的某个子游戏物体，需要先将该预制体UnPack，然后调用DestroyImmediate删除GameObeject，然后再保存预制体。这其实挺麻烦的，因为有时你拿到的gameObject是Asset中的资源，将预制体实例化后不好找到实例中对应的gameObject，拿名字找可以，但还是会有重名的风险。
我的方法无论传入的gameObject是处于场景中的实例还是处于Asset中都可以删除：文章来源地址https://www.toymoban.com/news/detail-502909.html

//删除预制体中的某个GameObject,不论其是不是在场景中的instance
    public static void DestroyGameObjectInPrefab(GameObject go)
    {
        if (PrefabUtility.IsPartOfAnyPrefab(go))
        {
            GameObject instance = null;
            GameObject deleteObj = null;
            bool isInAsset = EditorUtility.IsPersistent(go);
            if (isInAsset)
            {
                //在asset中
                var root = go.transform.root.gameObject;
                instance = PrefabUtility.InstantiatePrefab(root) as GameObject;
                deleteObj = GetCorrespondingGameObjectInInstance(instance.transform, go);
            }
            else
            {
                instance = PrefabUtility.GetOutermostPrefabInstanceRoot(go);
                deleteObj = go;
            }
            string prefabPath = PrefabUtility.GetPrefabAssetPathOfNearestInstanceRoot(instance);
            PrefabUtility.UnpackPrefabInstance(instance, PrefabUnpackMode.Completely, InteractionMode.AutomatedAction);
            GameObject.DestroyImmediate(deleteObj);
            PrefabUtility.SaveAsPrefabAsset(instance, prefabPath);
            if(isInAsset)
                GameObject.DestroyImmediate(instance);
        }
    }

    public static GameObject GetCorrespondingGameObjectInInstance(Transform root, GameObject assetObj)
    {
        if (PrefabUtility.GetCorrespondingObjectFromOriginalSource(root.gameObject) == assetObj)
        {
            return root.gameObject;
        }
        foreach (Transform child in root)
        {
            var ret = GetCorrespondingGameObjectInInstance(child, assetObj);
            if (ret != null)
                return ret;
        }
        return null;
