Unity自动场景保存脚本

新建一个名为AutoSave的编辑器脚本，并放于Assets/Editor下。

 using System;
 using UnityEditor;
 using UnityEditor.SceneManagement;
 using UnityEngine;
 using UnityEngine.SceneManagement;

 public class AutoSave : EditorWindow
 {
     private bool _autoSaveScene;
     private bool _showMessage;
     private bool _isStarted;
     private int _intervalScene;
     private DateTime _lastSaveTimeScene = DateTime.Now;

     private readonly string _projectPath = Application.dataPath;
     private string _scenePath;

     [MenuItem("Window/AutoSave")]
     private static void Init()
     {
         AutoSave saveWindow = (AutoSave) GetWindow(typeof (AutoSave));
         saveWindow.Show();
     }

     private void OnGUI()
     {
         GUILayout.Label("Info:", EditorStyles.boldLabel);
         EditorGUILayout.LabelField("Saving to:", "" + _projectPath);
         EditorGUILayout.LabelField("Saving scene:", "" + _scenePath);
         GUILayout.Label("Options:", EditorStyles.boldLabel);
         _autoSaveScene = EditorGUILayout.BeginToggleGroup("Auto save", _autoSaveScene);
         _intervalScene = EditorGUILayout.IntSlider("Interval (minutes)", _intervalScene, , );
         if (_isStarted)
         {
             EditorGUILayout.LabelField("Last save:", "" + _lastSaveTimeScene);
         }
         EditorGUILayout.EndToggleGroup();
         _showMessage = EditorGUILayout.BeginToggleGroup("Show Message", _showMessage);
         EditorGUILayout.EndToggleGroup();
     }

     private void Update()
     {
         _scenePath = SceneManager.GetActiveScene().path;
         if (_autoSaveScene)
         {
             if (DateTime.Now.Minute >= (_lastSaveTimeScene.Minute + _intervalScene) ||
                 DateTime.Now.Minute ==  && DateTime.Now.Second == )
             {
                 SaveScene();
             }
         }
         else
         {
             _isStarted = false;
         }

     }

     private void SaveScene()
     {
         EditorSceneManager.SaveScene(SceneManager.GetActiveScene());
         _lastSaveTimeScene = DateTime.Now;
         _isStarted = true;
         if (_showMessage)
         {
             Debug.Log("AutoSave saved: " + _scenePath + " on " + _lastSaveTimeScene);
         }
         AutoSave repaintSaveWindow = (AutoSave) GetWindow(typeof (AutoSave));
         repaintSaveWindow.Repaint();
     }
 }

在Window/AutoSave可以打开该面板，该脚本将自动识别项目路径并定时保存场景。
