Hi guys i was tweaking a lives counter prefab that was only showing in level one and was not visible in the other levels. I dropped it into my “Playspace” prefab containing my colliders, backgrounds etc, instead of adding it into that prefab I have accidentally overwrote the whole play space prefab!
Is there any way to revert to a previous version?
if undo doesn’t work for you, I believe your only option would be to revert to a previous commit in git. If you aren’t using source control, I doubt you can get it back. Sorry 
Actually another option if you haven’t customised it too much is to grab Ben’s code from github: https://github.com/CompleteUnityDeveloper/05-Block-Breaker
Thanks for the reply Ninja Chimp. I think im just going to have to redo it. How do i go about setting up a commit on git?
Do projects auto save in unity when you exit?
