平时开发中，Project窗口中可能会存在很多个scene,每次切换场景编辑的时候，需要到Project窗口中进行查找，非常麻烦，特别是引入的一些插件也自带了一些Scene。

那么有没有一种方式，可以快速的找到场景并进行切换呢？

今天我们就来解决下这个问题。

通过脚本遍历Project窗口中的所有scene 文件，并在菜单栏生成下拉列表，点击对应的场景就能快速的切换过去。

首先创建ScenesMenuBuild.cs 并将下面的代码复制进去

using System.Collections;using System.Collections.Generic;using System.IO;using System.Text;using UnityEditor;using UnityEditor.SceneManagement;using UnityEngine;/// Add a `Scenes` menu to Unity editor for quick access to all scenes in project.////// Generates/updates a `ScenesMenu.cs` file with the required menu annotations.public static class ScenesMenuBuild{ // Path on filesystem (relative to Assets directory) to write menu command scripts. // This can be inside any "Editor" folder. static readonly string ScenesMenuPath = "Scripts/Editor/ScenesMenu.cs"; [MenuItem("Scenes/Update This List")] public static void UpdateList() { string scenesMenuPath = Path.Combine(Application.dataPath, ScenesMenuPath); var stringBuilder = new StringBuilder(); stringBuilder.AppendLine("// Generated file"); stringBuilder.AppendLine("using UnityEditor;"); stringBuilder.AppendLine("using UnityEditor.SceneManagement;"); stringBuilder.AppendLine("public static class ScenesMenu"); stringBuilder.AppendLine("{"); foreach (string sceneGuid in AssetDatabase.FindAssets("t:Scene", new string[] { "Assets" })) { string sceneFilename = AssetDatabase.GUIDToAssetPath(sceneGuid); string sceneName = Path.GetFileNameWithoutExtension(sceneFilename); string methodName = sceneFilename.Replace('/', '_').Replace('\\', '_').Replace('.', '_').Replace('-','_'); stringBuilder.AppendLine(string.Format(" [MenuItem(\"Scenes/{0}\", priority = 10)]",sceneName)); stringBuilder.AppendLine(string.Format(" public static void {0}() {{ ScenesMenuBuild.OpenScene(\"{1}\"); }}",methodName,sceneFilename)); } stringBuilder.AppendLine("}"); Debug.LogError(Path.GetDirectoryName(scenesMenuPath)+">>>>>>>****"); Directory.CreateDirectory(Path.GetDirectoryName(scenesMenuPath)); File.WriteAllText(scenesMenuPath, stringBuilder.ToString()); AssetDatabase.Refresh(); } public static void OpenScene(string filename) { if (EditorSceneManager.SaveCurrentModifiedScenesIfUserWantsTo()) EditorSceneManager.OpenScene(filename); }}

会在菜单栏出现Scenes选项，如下图

点击Update This List ,则会在Assets目录下生成Scripts/Editor/ScenesMenu.cs，该脚本的内容就是每个scene对应的MenuItem.此时就可以在Scenes下拉列表里面快速的切换场景进行编辑了。
