Unity 创建文件夹怎么能像他自带的创建文件夹那样可以自己 ...

正常咱们官网查到的Unity API
public static string CreateFolder (string parentFolder, string newFolderName);
但是这样的话就只能创建固定的命名了。
所以我查了一下官网的Create Folder是怎么实现的
// Create a folder
      [ShortcutManagement.ShortcutAttribute(&#34;Project Browser/Create/Folder&#34;, typeof(ProjectBrowser), KeyCode.N, ShortcutManagement.ShortcutModifiers.Shift | ShortcutManagement.ShortcutModifiers.Action)]
      public static void CreateFolder()
      {
         StartNameEditingIfProjectWindowExists(0, ScriptableObject.CreateInstance<DoCreateFolder>(), &#34;New Folder&#34;, EditorGUIUtility.IconContent(EditorResources.emptyFolderIconName).image as Texture2D, null);
      }

她是用了一个StartNameEditingIfProjectWindowExists的方法
我查了一下这个方法
public static void StartNameEditingIfProjectWindowExists(int instanceID, EndNameEditAction endAction, string pathName, Texture2D icon, string resourceFile)
附上地址：Site not found · GitHub Pages)](Class ProjectWindowUtil
他`EndNameEditAction`有一个Action，官网是这么写的
internal class DoCreateFolder : EndNameEditAction
      {
         public override void Action(int instanceId, string pathName, string resourceFile)
         {
            string guid = AssetDatabase.CreateFolder(Path.GetDirectoryName(pathName), Path.GetFileName(pathName));
            Object o = AssetDatabase.LoadAssetAtPath(AssetDatabase.GUIDToAssetPath(guid), typeof(Object));
            ProjectWindowUtil.ShowCreatedAsset(o);
         }
      }
因为我只需要在最外层命名，里面的结构都是写死的，所以我重写了这个方法来实现我需要再里面嵌套其它文件夹。
using System.IO;
using UnityEditor;
using UnityEditor.Experimental;
using UnityEditor.ProjectWindowCallback;
using UnityEngine;

public class CreateArtResFolder : Editor
{
[MenuItem(&#34;Assets/Create/Folder.ArtRes&#34;, priority = 15)]
static void Init()
{
      CreateArtFolder();
      Debug.Log(&#34;已创建文件夹&#34;);
}

static void CreateArtFolder()
{
      ProjectWindowUtil.StartNameEditingIfProjectWindowExists(0, CreateInstance<DoCreateFolder>(), &#34;New Folder&#34;, EditorGUIUtility.IconContent(EditorResources.folderIconName).image as Texture2D, null);
}
}

internal class DoCreateFolder : EndNameEditAction
{
public override void Action(int instanceId, string pathName, string resourceFile)
{
      string guid = AssetDatabase.CreateFolder(Path.GetDirectoryName(pathName), Path.GetFileName(pathName));
      AssetDatabase.CreateFolder(pathName, &#34;Materials&#34;);
      Object o = AssetDatabase.LoadAssetAtPath(AssetDatabase.GUIDToAssetPath(guid), typeof(Object));
      ProjectWindowUtil.ShowCreatedAsset(o);
}
}

在底下DoCreateFolder类里面写内层的文件夹结构
增加一个AssetDatabase.CreateFolder(pathName, &#34;Materials&#34;);
pathName可以直接拿到的当前创建好后的文件夹完整内部路径，所以可以按照这个思路往里面添加其它文件夹。
