Unity最新一键清理Prefab中所有MissingComponent

因为老的API  Properties.DeleteArrayElementAtIndex(propertyIndex);提示没权限修改，

而unity提供了新的API  GameObjectUtility.RemoveMonoBehavioursWithMissingScript(go); 更方便移除丢失的组件，需要遍历物体下面所有子节点，否则无法移除子节点的丢失组件。

于是重新整理了下清理的编辑器代码，直接贴上：

using System;
using UnityEngine;
using UnityEditor;

public class ResTool : Editor
{
    [MenuItem("Tools/清理prefab中所有Missing的脚本")]
    public static void ClearAllPrefabMissingComponents()
    {
        EditorUtility.DisplayProgressBar("Modify Prefab", "Please wait...", 0);
        string[] assetGUIDs = AssetDatabase.FindAssets("t:Prefab", new string[] { "Assets/Res/Prefab" });
        try
        {
            for (int i = 0; i < assetGUIDs.Length; i++)
            {
                string path = AssetDatabase.GUIDToAssetPath(assetGUIDs[i]);
                // Debug.Log($"path:{path}");
                GameObject pre = PrefabUtility.LoadPrefabContents(path);

                DeleteRecursive(pre, (go) =>
                {
                    GameObjectUtility.RemoveMonoBehavioursWithMissingScript(go);
                });
                PrefabUtility.SaveAsPrefabAssetAndConnect(pre, path, InteractionMode.AutomatedAction);

                EditorUtility.DisplayProgressBar($"清理Prefab丢失组件", $"当前{pre}, {i}/{assetGUIDs.Length}", i / (float)assetGUIDs.Length);
            }
        }
        catch (Exception e)
        {
            Debug.LogError($"{e}");
        }
        
        AssetDatabase.SaveAssets();
        EditorUtility.ClearProgressBar();
        AssetDatabase.Refresh();
    }

    /// <summary>
    /// 遍历所有子节点
    /// </summary>
    /// <param name="obj"></param>
    /// <param name="action"></param>
    static void DeleteRecursive(GameObject obj, Action<GameObject> action)
    {
        action(obj);

        for (int i = 0; i < obj.transform.childCount; i++)
        {
            DeleteRecursive(obj.transform.GetChild(i).gameObject, action);
        }

    }
    
}
