00:00:00,760 --> 00:00:06,840
Can you imagine if you had to repeat something
forever and ever? Hopefully you'll never have

2
00:00:06,840 --> 00:00:13,220
to because computers are really good at repeating
things. This is the "repeat forever" block.

3
00:00:13,220 --> 00:00:17,940
Anything inside this block will happen forever
in the game. So if we wanted an actor to do

4
00:00:17,940 --> 00:00:22,710
something repeatedly without the player having
to do anything, we'll put those blocks inside

5
00:00:22,710 --> 00:00:28,619
the "repeat forever" block. In this next puzzle,
our goal is to help Anna walk up and down

6
00:00:28,619 --> 00:00:33,920
continuously. Learning how the repeat commands
work will save you a ton of time later when

7
00:00:33,920 --> 00:00:35,289
you build your own game.
