3、AssetBundle统一管理命名

代码参考蛮牛教育CTO教你万能框架教程

利用Editor统一AssetBundle的命名规则。

文件结构如下所示

命名规则:

1.对Art/Scenes下文件进行命名，所有文件的AssetBundleName为Scenes下二级子文件夹名称，例如：Cube(1)的assetBundleName为sceneone/font

2.其中普通文件.ld，场景文件后缀.u3d

代码如下

using System.Collections.Generic;using System.IO;using UnityEditor;using UnityEngine;public class AssetBundleEditor : Editor{    [MenuItem("ITools/BuildeAssetBundle")]    public static void BuildAssetBundle()    {        BuildPipeline.BuildAssetBundles(Application.dataPath + "/AssetBundle", 0, EditorUserBuildSettings.activeBuildTarget);        //刷新        AssetDatabase.Refresh();    }    [MenuItem("ITools/MarkAssetBundle")]    public static void MarkAssetBundle()    {        AssetDatabase.RemoveUnusedAssetBundleNames();        string path = Application.dataPath + "/Art/Scenes";
