Unity编辑器中如何扩展场景创建功能，实现后续流程自动化？

完全可行，Unity的Editor扩展机制可以完美实现你要的功能——直接扩展右键菜单、弹出配置对话框，一键完成场景创建+Addressable配置+ScriptableObject关联全流程。下面是具体实现思路和代码示例：

核心实现步骤 #

1. 扩展Project视图右键菜单 #

用UnityEditor的MenuItem特性，在Assets/Create菜单下添加自定义选项，设置优先级让它挨着默认Scene选项显示：

using UnityEngine;
using UnityEditor;
using System.IO;

public class CustomSceneCreator
{
    // 优先级设为101（默认Scene是100），让选项排在默认Scene下方
    [MenuItem("Assets/Create/自动化场景", false, 101)]
    public static void ShowCustomSceneDialog()
    {
        // 获取右键点击的目标文件夹路径
        string targetFolder = "Assets";
        if (Selection.activeObject != null)
        {
            targetFolder = AssetDatabase.GetAssetPath(Selection.activeObject);
            // 如果选中的是文件，取它所在的文件夹
            if (!Directory.Exists(targetFolder))
            {
                targetFolder = Path.GetDirectoryName(targetFolder);
            }
        }
        
        // 弹出配置窗口
        CustomSceneConfigWindow.ShowWindow(targetFolder);
    }
}

2. 制作配置对话框 #

用EditorWindow做一个轻量弹窗，让用户输入场景名、勾选需要的自动化操作：

using UnityEditor;
using UnityEngine;

public class CustomSceneConfigWindow : EditorWindow
{
    private string sceneName = "NewScene";
    private bool makeAddressable = true;
    private bool addToSceneListSO = true;
    private string targetFolder;

    public static void ShowWindow(string folder)
    {
        var window = GetWindow<CustomSceneConfigWindow>("场景配置");
        window.targetFolder = folder;
        window.minSize = new Vector2(300, 150);
    }

    private void OnGUI()
    {
        GUILayout.Label("场景创建配置", EditorStyles.boldLabel);
        
        sceneName = EditorGUILayout.TextField("场景名称", sceneName);
        makeAddressable = EditorGUILayout.Toggle("设为Addressable", makeAddressable);
        addToSceneListSO = EditorGUILayout.Toggle("添加到场景列表SO", addToSceneListSO);

        if (GUILayout.Button("创建并配置"))
        {
            CreateAndConfigureScene();
            Close();
        }
    }

    private void CreateAndConfigureScene()
    {
        SceneCreationUtils.CreateScene(targetFolder, sceneName, makeAddressable, addToSceneListSO);
    }
}

3. 实现自动化配置逻辑 #

封装一个工具类，处理场景创建、Addressable配置、ScriptableObject关联的具体逻辑：

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

public static class SceneCreationUtils
{
    public static void CreateScene(string targetFolder, string sceneName, bool makeAddressable, bool addToSO)
    {
        // 1. 创建并保存场景
        string scenePath = Path.Combine(targetFolder, $"{sceneName}.unity");
        var newScene = UnityEditor.SceneManagement.EditorSceneManager.NewScene(
            UnityEditor.SceneManagement.NewSceneSetup.DefaultGameObjects, 
            UnityEditor.SceneManagement.NewSceneMode.Single
        );
        UnityEditor.SceneManagement.EditorSceneManager.SaveScene(newScene, scenePath);
        AssetDatabase.Refresh();

        // 2. 配置Addressable
        if (makeAddressable)
        {
            var addressableSettings = AddressableAssetSettingsDefaultObject.Settings;
            if (addressableSettings == null)
            {
                Debug.LogError("未初始化Addressable设置，请先开启Addressable系统");
                return;
            }
            
            // 获取默认组（可按需修改为指定分组）
            var defaultGroup = addressableSettings.DefaultGroup;
            var sceneAsset = AssetDatabase.LoadAssetAtPath<SceneAsset>(scenePath);
            // 添加到Addressable并设置标识
            var entry = addressableSettings.CreateOrMoveEntry(AssetDatabase.AssetPathToGUID(scenePath), defaultGroup);
            entry.address = sceneName;
            entry.labels.Add("Scene");
            AddressableAssetSettings.Save(addressableSettings);
        }

        // 3. 添加到ScriptableObject
        if (addToSO)
        {
            // 替换为你自己的场景列表SO路径
            var sceneListSO = AssetDatabase.LoadAssetAtPath<SceneListSO>("Assets/Resources/SceneListSO.asset");
            if (sceneListSO != null)
            {
                var sceneAsset = AssetDatabase.LoadAssetAtPath<SceneAsset>(scenePath);
                sceneListSO.scenes.Add(sceneAsset);
                EditorUtility.SetDirty(sceneListSO);
                AssetDatabase.SaveAssets();
            }
            else
            {
                Debug.LogError("未找到SceneListSO，请确认路径正确");
            }
        }

        Debug.Log($"场景 {sceneName} 已创建并完成配置");
    }
}

// 示例场景列表ScriptableObject（按需修改字段）
[CreateAssetMenu(fileName = "SceneListSO", menuName = "ScriptableObjects/场景列表")]
public class SceneListSO : ScriptableObject
{
    public List<SceneAsset> scenes = new List<SceneAsset>();
}

注意事项 #

• 确保已导入Addressable包，否则UnityEditor.AddressableAssets命名空间会报错
• 提前创建好你的场景列表ScriptableObject，并修改代码中的对应路径
• 所有代码需放在Editor文件夹下，避免打包时出现编译错误
• 可根据需求扩展对话框选项，比如让用户选择Addressable分组、自定义标签等
