很多时候，在编写项目时，遇见unity 的Buge导致强制退出，这时根本来不及保存hierarchy视图中的东西，这是一件很糟糕的事情，所以在今天看资料时，有幸的看到了这篇自动保存项目场景的源码。很是不错。
源码如下：
1 using UnityEngine;
2 using UnityEditor;
3 using System;
4
5 public class AutoSave : EditorWindow
6 {
7
8 private bool autoSaveScene = true;
9 private bool showMessage = true;
10 private bool isStarted = false;
11 private int intervalScene;
12 private DateTime lastSaveTimeScene = DateTime.Now;
13
14 private string projectPath = Application.dataPath;
15 private string scenePath;
16
17 [MenuItem("Window/AutoSave")]
18 static void Init()
19 {
20 AutoSave saveWindow = (AutoSave)EditorWindow.GetWindow(typeof(AutoSave));
21 saveWindow.Show();
22 }
23
24 void OnGUI()
25 {
26 GUILayout.Label("Info:", EditorStyles.boldLabel);
27 EditorGUILayout.LabelField("Saving to:", "" + projectPath);
28 EditorGUILayout.LabelField("Saving scene:", "" + scenePath);
29 GUILayout.Label("Options:", EditorStyles.boldLabel);
30 autoSaveScene = EditorGUILayout.BeginToggleGroup("Auto save", autoSaveScene);
31 intervalScene = EditorGUILayout.IntSlider("Interval (minutes)", intervalScene, 1, 10);
32 if (isStarted)
33 {
34 EditorGUILayout.LabelField("Last save:", "" + lastSaveTimeScene);
35 }
36 EditorGUILayout.EndToggleGroup();
37 showMessage = EditorGUILayout.BeginToggleGroup("Show Message", showMessage);
38 EditorGUILayout.EndToggleGroup();
39 }
40
41
42 void Update()
43 {
44 scenePath = EditorApplication.currentScene;
45 if (autoSaveScene)
46 {
47 if (DateTime.Now.Minute >= (lastSaveTimeScene.Minute + intervalScene) || DateTime.Now.Minute == 59 && DateTime.Now.Second == 59)
48 {
49 saveScene();
50 }
51 }
52 else
53 {
54 isStarted = false;
55 }
56
57 }
58
59 void saveScene()
60 {
61 EditorApplication.SaveScene(scenePath);
62 lastSaveTimeScene = DateTime.Now;
63 isStarted = true;
64 if (showMessage)
65 {
66 Debug.Log("AutoSave saved: " + scenePath + " on " + lastSaveTimeScene);
67 }
68 AutoSave repaintSaveWindow = (AutoSave)EditorWindow.GetWindow(typeof(AutoSave));
69 repaintSaveWindow.Repaint();
70 }
71 }
值得注意的是：创建好这个脚本后，放在Assets/Editor文件夹中，然后编辑的窗口再Window目录下。
在激活状态下，才可有效。希望对大家有所帮助。
