Can you imagine if you had to repeat something forever and ever? Well hopefully you never
have to, because computers are really good at repeating things for you. This is the "repeat
forever" block. Anything inside this block will happen forever in the game. If we want
an actor to do something repeatedly, without the player having to do anything, we'll put
those blocks inside the "repeat forever" block. In this next puzzle, our goal is to help the
wizard patrol the boundaries of the kingdom, left and right continuously. Learning how
the repeat commands works, will save you a ton of time later when you build your own game.
