【Unity3D】自制小工具批量设置AB包名

         最近一个项目要用到批量的设置AB包名，由于同一类的资源在一个文件夹内，所以就查着资料写了一个小工具，以文件夹为单位批量修改内部的资源包名，方便打包，话不多说直接上代码吧：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using UnityEditor;
using UnityEngine;

public class SetAssetBundleName : EditorWindow
{
    //******系统设置
    //一种系统样式，使用他可以使控件周围表现为一个BOX的模样
    private GUIStyle _box = new GUIStyle("Box");

    //******窗口参数
    private Vector2 _FilesScrollValue;//当前文件滚动的位置

    //******资源参数
    static List<stru_FileInfo> list_Files;//文件列表

    string assetBundleName;
    string assetBundleVariant = "";
    //int indentation;//缩进等级
    struct stru_FileInfo
    {
        public string fileName;
        public string filePath;//绝对路径
        public string assetPath;//U3D内部路径
        public Type assetType;
    }
    
    [MenuItem("Assets/AssetBundle工具箱/设置AB包名")]
    private static void OpenSetAssetBundleNameWindow()
    {
        list_Files = new List<stru_FileInfo>();
        //indentation = 1;
        CheckFileSystemInfo();
        SetAssetBundleName ABNameWin = GetWindow<SetAssetBundleName>("设置AssetBundlesName");
        ABNameWin.position = new Rect(300, 100, 300,500);
        ABNameWin.minSize = new Vector2(300, 500);
        ABNameWin.Show();
    }
    private void OnGUI()
    {
        //设置GUI label参数
        GUI.skin.label.fontSize = 10;
        GUI.skin.label.alignment = TextAnchor.MiddleLeft;
        FilesGUI();
        SetABNameGUI();
    }
    void FilesGUI()
    {
        //标题
        GUILayout.Space(5);
        EditorGUILayout.BeginHorizontal();
        GUILayout.Space(150);
        if (GUILayout.Button("刷新资源", _box))
        {
            list_Files.Clear();
            CheckFileSystemInfo();
        }
        EditorGUILayout.EndHorizontal();

        GUI.Label(new Rect(5, 35, 100, 20), "选中" + list_Files.Count + "项资源：");
        GUILayout.Space(10);

        _FilesScrollValue = EditorGUILayout.BeginScrollView(_FilesScrollValue, _box, GUILayout.MaxHeight(300));
        AddFileGUIToScroll();
        EditorGUILayout.EndScrollView();

        //GUI.EndGroup();
    }
    /// <summary>

    void AddFileGUIToScroll()

            GUILayout.BeginVertical();
            //获取系统中的文件夹图标

            //以lable展示
            GUILayout.Label(content, GUILayout.Height(20));
            
            GUILayout.EndVertical();
        }
    }

    {

        //设置包名
        GUILayout.Space(20);

        EditorGUILayout.BeginHorizontal();
        assetBundleVariant = EditorGUILayout.TextField("资源拓展名：", assetBundleVariant);
        EditorGUILayout.EndHorizontal();

    #endregion
}

使用方法即使选中要修改 的文件夹右键，或者在工具栏里点击Assets --->AssetBundle工具箱---> 设置AB包名，即可！

注意包号assetBundleVariant可为空，也可以自己输入，个人理解是区分相同资源的不同版本···有点绕············
