Unity double save/back-up

Questions & Answers
1

Hello, I would like to know if there is a way to double save the project when you hit file > save scene. I have never created an editor script before but i think I should do it this way : EditorApplication.SaveScene.
I would like to save the scene in the normal folder and also in a extern hard drive. Something like this :

File > Save Scene => save the scene in:

  • C:\Unity projects\Puzzle
  • E:\Unity projects\Puzzle, this is my extern hard drive.

Could anyone help me out? Thanks in advance

The issue, of course, is listening for the save event when the user goes to File > Save Scene. As far as I'm aware there's no way to register a listener for this event, so you have a few options:

  • Create your own menu button for double saving that saves a copy to http://unity3d.com/support/documentation/ScriptReference/EditorApplication-currentScene.html and a copy to somewhere you specify (or you can try calling http://unity3d.com/support/documentation/ScriptReference/EditorApplication.ExecuteMenuItem.html)

  • Use the editor update function to check for changes to the scene file and save out a copy when it changes (which I don't recommend)

  • Look for other events and perform a save when you see them. E.g., look for isCompiling or isPlayingOrWillChangePlaymode and save then.
