Minecraft Hour of Code - Repeat Loops

Stampy: I wonder what Stacy is up to?

Stacy: Woah, I think I'm in the right place.

This is amazing!

I feel like I'm back in Minecraft!

Hello.

How are you?

Hello?

Oh, there's a creeper. You don't do anything, do you?

Katie: Stacy?

Stacy:Hi, Katie?

Katie: Yes!

Welcome to Minecraft.

Stacy: Thank you!

Katie: Come on in!

Stacy: This is amazing.

So you work here every day as a developer,
right?

Katie: Yeah, it's pretty awesome.

I'm a developer on the Minecraft marketplace
team.

Stacy: How many coding languages do you know?

Katie: In my career I've probably worked with
over a dozen.

Stacy: A dozen?

Katie: Yeah.

Stacy: So now, you wouldn't happen to know
anything about this little golem guy that

calls himself "the Agent"?

Katie: We use the Agent to do things that
Steve or Alex can't, like go across lava.

Stacy: Well, I want to learn how to code,
and they want to learn how to code, so what

is one of the first things that you need to
know when you're learning?

Katie: Well, you need to learn how to use
loops.

Stacy: Ok.

Katie: Loops are things that developers write
to give commands to a computer that can be

run over and over again.

Stacy: Got it, so I think there's actually
some of that coming up in the levels ahead,

so go ahead and give loops a try.

In the next level, you can use a loop to move
the Agent along the path.

Drag the repeat block into the workspace and
place the move forward block inside the repeat

block.

This tells the computer to do the same thing
many times in a row without having to drag

a whole bunch of blocks into the workspace.

You can choose how many times to repeat by
putting a number in the repeat block.

You can put turns and multiple commands in
the repeat block too, but for now try using

a repeat to move the Agent forward a few steps.

Remember, if you get stuck on a puzzle you
can always hit the blue "reset" button and

try again.

If you are thinking about having a cool job
like Katie's, go ahead and click the "show

code" button when you finish every level.

That's going to actually show you the Javascript
code that someone like Katie uses when she's

actually programming Minecraft.

So anyway, thank you so much!

Katie: Yeah, good luck everyone!
