    }
    void OnGUI () {

        if(isStarted) {
            EditorGUILayout.LabelField ("Last save:", ""+lastSaveTimeScene);
        }

        if(autoSaveScene) {
            if(DateTime.Now.Minute >= (lastSaveTimeScene.Minute+intervalScene) || DateTime.Now.Minute ==  && DateTime.Now.Second == ){
                saveScene();
            }
        } else {
            isStarted = false;
        }
    }
    void saveScene() {
        EditorApplication.SaveScene(scenePath);
        lastSaveTimeScene = DateTime.Now;
        isStarted = true;
        if(showMessage){
            Debug.Log("AutoSave saved: "+scenePath+" on "+lastSaveTimeScene);
        }
        AutoSave repaintSaveWindow = (AutoSave)EditorWindow.GetWindow (typeof (AutoSave));
        repaintSaveWindow.Repaint();
    }
}

因为这个编辑窗口必须在激活状态，所以 你可以把它附属在某个窗口下面 比如Project视图。
