Click on the cat to drag it around. If you want to use the scripts, take a look inside for comments.
I don't see the lock/unlock dragability feature in 2.0, so I made a script for it. If anyone knows how to do this, please let me know! I hope this can be of some use to you. I'm working on something that uses dragable sprites but I wanted to share this in its simplest form so it's easier to remix and not embedded in a game.
