Well, hello, my name is Charita Carter. I'm
a senior creative producer here at Walt Disney

00:00:05.200 --> 00:00:09.550
Imagineering. I'm responsible for leading
teams that actually produce the attractions

00:00:09.550 --> 00:00:16.569
that our guests get to experience. We are
always looking for ways that we can improve

00:00:16.569 --> 00:00:21.220
and make a better experience for our guests
and technology is at the heart of that.

00:00:21.220 --> 00:00:27.640
Congratulations, you did it! You programmed
BB-8. Now I think we're ready for something

00:00:27.640 --> 00:00:33.250
harder. Let's go for it. Now that you've learned
the basics of programming, we're going to

00:00:33.250 --> 00:00:40.160
back in time to build your own game, starring
R2-D2 and C3PO. To make a game, we need to

00:00:40.160 --> 00:00:45.989
learn about something that game programmers
use every day: they're called events.

00:00:45.989 --> 00:00:51.089
Events tell your program to listen or wait
for when something happens and then when it

00:00:51.089 --> 00:00:56.829
does, it performs an action. Some examples
of events are listening for a mouse click,

00:00:56.829 --> 00:01:02.710
an arrow button or a tap on the screen. Here
we're going to make R2-D2 move up to deliver

00:01:02.710 --> 00:01:07.090
a message to a rebel pilot and then move down
to the other rebel pilot.

00:01:07.090 --> 00:01:12.570
We'll use events to make him move. When the
player uses the up/down arrow keys, or the

00:01:12.570 --> 00:01:19.549
up/down buttons. We use the when up event
block and attach the go up block to it. When

00:01:19.549 --> 00:01:25.270
the player presses the up arrow key, the code
attached to the when up block is run. And

00:01:25.270 --> 00:01:28.710
we'll do the same thing to make R2-D2 move
down.

00:01:28.710 --> 00:01:34.740
Now instead of writing all the code to control
our droid in advance, we can let R2-D2 react

00:01:34.740 --> 00:01:40.810
to button press events that move him around
the screen. Step by step, your game is getting

00:01:40.810 --> 00:01:42.510
more interactive.
