@Redstone you copied it from Friaza, just wow really...

Look, if you want to learn it, how to do it, all you gotta to is CFrame IF You want to be all fancy and unique. But, give it a shot without copying what RedStone posted just read it, get the Main Idea and give it a shot. If you manage to make it, you know you did a good job, if not, well you tried and you ask it again. It's better to try even though you fail. It's good to know if you were close or not
