Unity一键制作预制体Prefab一键修改Prefab属性

1.适用于制作多个预制体(一个模型文件下面几百个子物体,都需要制作成预制体,这一个一个拖不是要炸裂)

模型资源如下图

2.模型先放到Resources文件夹下面方便读取,制作完预制体可以给他拖到其他文件夹

模型文件结构如下图(经测试放模型的文件夹名字要和模型名字一致,不然找不到,你也可以修改代码测试其他方法)

3.下面是编辑器脚本

using System.Collections;using System.Collections.Generic;using System.IO;using System.Text.RegularExpressions;using UnityEditor;using UnityEngine;/// <summary>/// 编辑器脚本/// </summary>public class CreationPrefab : EditorWindow{[MenuItem("Tools/一键生成Prefab")]public static void CreatePrefabWindow(){EditorWindow window = EditorWindow.GetWindowWithRect(typeof(CreationPrefab), new Rect(Screen.width / 3, Screen.height / 3, 800, 500), true, "CreationPrefab");window.Show();}//保存prefab的路径private static string toSavePrefabPath = "Assets/Prefabs/新模型库/机柜内设备";private void OnGUI(){EditorGUILayout.LabelField("预制体保存路径：:", toSavePrefabPath, GUILayout.Width(110));toSavePrefabPath = EditorGUILayout.TextArea(toSavePrefabPath, GUILayout.Width(250));if (GUILayout.Button("转换预制体", GUILayout.Width(260))){ToPrefab();}if (GUILayout.Button("修改预制体", GUILayout.Width(260))){ModifyPrefab(toSavePrefabPath);}}private void ToPrefab(){string path = "Assets/Resources";string[] allFolder1 = GetAllFolder(path);if (allFolder1 == null)return;//循环次数取决于 ，源文件的目录结构 ，此处为 4 级结构 //也就是Resources下面4级文件夹,到达模型文件夹 一级一个for循环for (int i = 0; i < allFolder1.Length; i++){string path2 = $"{path}/{allFolder1[i]}";string[] allFolder2 = GetAllFolder(path2);if (allFolder2 == null){return;}for (int j = 0; j < allFolder2.Length; j++){string path3 = $"{path2}/{allFolder2[j]}";string[] allFolder3 = GetAllFolder(path3);if (allFolder3 == null)return;for (int k = 0; k < allFolder3.Length; k++){string path4 = $"{path3}/{allFolder3[k]}";string[] allFolder4 = GetAllFolder(path4);Debug.Log($"编号：{k}{allFolder3[k]}文件下有 {allFolder4.Length} 个文件夹！");if (allFolder4 == null)return;if (!Directory.Exists(toSavePrefabPath)){Directory.CreateDirectory(toSavePrefabPath);}for (int l = 0; l < allFolder4.Length; l++){string speedTree = $"{path4}/{allFolder4[l]}/{allFolder4[l]}";string[] strs = Regex.Split(speedTree, path + "/", RegexOptions.IgnoreCase);GameObject go = Instantiate(GetFileObj(strs[1]));go.name = go.name.Replace("(Clone)", string.Empty);//给预制体添加脚本，修改属性//go.transform.tag = "Model";//if (go.GetComponent<BoxCollider>() == null)// go.AddComponent<BoxCollider>();//if (go.GetComponent<Rigidbody>() == null)// go.AddComponent<Rigidbody>();//go.GetComponent<Rigidbody>().isKinematic = true;string modeName = allFolder4[l].Split('_')[0];for (int p = 0; p < go.transform.childCount; p++){PrefabUtility.SaveAsPrefabAsset(go.transform.GetChild(p).gameObject, $"{toSavePrefabPath}/{go.transform.GetChild(p).name}.prefab");}DestroyImmediate(go);}AssetDatabase.Refresh();}}}}/// <summary>/// 获取路径下的 Obj/// </summary>/// <param name="path"></param>/// <returns></returns>private GameObject GetFileObj(string path){GameObject go = Resources.Load<GameObject>(path);if (go != null){return go;}else{Debug.Log(path);return null;}}/// <summary>/// 获取路径下的所有文件夹/// </summary>/// <param name="path"></param>/// <returns></returns>private string[] GetAllFolder(string path){try{string[] dirs = Directory.GetDirectories(path, "*");string[] folderName = new string[dirs.Length];for (int i = 0; i < dirs.Length; i++){string file = dirs[i].Split('\\')[1];folderName[i] = file;}return folderName;}catch (System.Exception){return null;}}/// <summary>/// 修改预制体/// </summary>/// <param name="path"></param>private void ModifyPrefab(string path){//获取文件下所有预制体文件DirectoryInfo info = new DirectoryInfo(path);FileInfo[] fileInfos = info.GetFiles("*.prefab"); List<GameObject> prefabs = new List<GameObject>();foreach (var item in fileInfos){string paths = $"{path}/{item.Name}";GameObject prefab = AssetDatabase.LoadAssetAtPath(paths, typeof(GameObject)) as GameObject;prefabs.Add(prefab);}Debug.Log("执行么" + prefabs.Count);//修改属性for (int i = 0; i < prefabs.Count; i++){//修改预制体的position和旋转角度if (prefabs[i].GetComponent<Transform>() != null){prefabs[i].GetComponent<Transform>().position = Vector3.zero;prefabs[i].GetComponent<Transform>().rotation = Quaternion.Euler(Vector3.zero);}//其他属性请自行添加即可//if (prefabs[i].GetComponent<Rigidbody>() != null)//{// prefabs[i].GetComponent<Rigidbody>().isKinematic = false;// PrefabUtility.SavePrefabAsset(prefabs[i]);//}}AssetDatabase.SaveAssets();AssetDatabase.Refresh();}}

两个功能一个生成预制体,一个修改预制体的坐标和角度为0

功能显示位置如下图

编辑器脚本需放到Editor文件夹下面
