Unity 编辑器扩展 一键替换指定物体下的所有材质球

先看效果

实现方案

1：创建几个用于测试的Cube

2：创建一个脚本

3:编写脚本内容

主要是这部分的逻辑

附上完整代码

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEngine;public class Tool
{[MenuItem("TOOL/ReplaceMaterial")]public static void Open(){var window = EditorWindow.GetWindow(typeof(ReplaceMA));window.title = "材质球替换工具";}
}
public class ReplaceMA : EditorWindow
{private GameObject _GameObject;private Material _Material;private void OnGUI(){if (!Application.isPlaying){GUILayout.Label("拖入一个你想替换材质球的游戏物体");_GameObject = (GameObject)EditorGUILayout.ObjectField(_GameObject, typeof(GameObject), true);GUILayout.Label("拖入一个你想替换的材质球");_Material = (Material)EditorGUILayout.ObjectField(_Material, typeof(Material), true);if (GUILayout.Button("点击替换")){if (_GameObject == null || _Material == null){Debug.LogError("你要替换材质的游戏物体或者材质球为空");return;}var RenderList = new List<Renderer>();RenderList.Add(_GameObject.gameObject.GetComponent<Renderer>());RenderList.AddRange(_GameObject.GetComponentsInChildren<Renderer>());Undo.RecordObjects(RenderList.ToArray(), "Replace");//这句话非常重要，不然得气死个人！！！foreach (var item in RenderList){var materials = item.sharedMaterials;for (int i = 0; i < materials.Length; i++){materials[i] = _Material;}item.sharedMaterials = materials;}}}}
}

4，然后就完成啦，同样你也可以按照我的思路再扩展扩展，可以替换你自己想要的内容
