I have been using Unity for two weeks now and have created a game I am proud of.
BUT today I wanted to make a copy of my Asset folder and put it on my Desktop (I am running Mac), but by mistake I dragged the folder out of the game. I dragged the folder back in again, but then all scripts and items were gone.
What can I do to get my game back!?!
:-x
You may have to reimport all assets and hook things up again manually. Ideally you would just restore from the most recent backup, though. Since you’re using a Mac, always run Time Machine after making any significant changes (or leave it on auto). By the way, making a copy of the Assets folder won’t accomplish anything; you need to copy the entire project.

Thank for your help, will try this. 
Hope it works!!
sorry, but just one question. How do I do it? Where must I be positioned?
