先看演示效果

实现方案

1创建几个用于测试的cube

2，创建一个Editor脚本

3，编写脚本内容

附上源码

using UnityEditor;
using UnityEngine;public class GetPrefeb : EditorWindow
{private string folderPath = "Assets/Resources"; // 指定预制体文件夹路径[MenuItem("Tool/Prefab Browser Window")]public static void ShowWindow(){GetWindow<GetPrefeb>("Prefab Browser");}private void OnGUI(){folderPath = EditorGUILayout.TextField("Folder Path: ", folderPath);if (GUILayout.Button("List Prefabs")){ListPrefabsInFolder(folderPath);}}private void ListPrefabsInFolder(string folderPath){string[] guids = AssetDatabase.FindAssets("t:Prefab", new string[] { folderPath });foreach (string guid in guids){string assetPath = AssetDatabase.GUIDToAssetPath(guid);GameObject prefab = AssetDatabase.LoadAssetAtPath<GameObject>(assetPath);Debug.Log("Prefab" + assetPath);//这里处理你的逻辑}}
}

4.赶紧去试试吧，对获取到的预制件做自己的逻辑处理
