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

2
00:00:05,200 --> 00:00:09,550
Imagineering. I'm responsible for leading
teams that actually produce the attractions

3
00:00:09,550 --> 00:00:16,569
that our guests get to experience. We are
always looking for ways that we can improve

4
00:00:16,569 --> 00:00:21,220
and make a better experience for our guests
and technology is at the heart of that.

5
00:00:21,220 --> 00:00:27,640
Congratulations, you did it! You programmed
BB-8. Now I think we're ready for something

6
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

7
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

8
00:00:40,160 --> 00:00:45,989
learn about something that game programmers
use every day: they're called events.

9
00:00:45,989 --> 00:00:51,089
Events tell your program to listen or wait
for when something happens and then when it

10
00:00:51,089 --> 00:00:56,829
does, it performs an action. Some examples
of events are listening for a mouse click,

11
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

12
00:01:02,710 --> 00:01:07,090
a message to a rebel pilot and then move down
to the other rebel pilot.

13
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

14
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

15
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

16
00:01:25,270 --> 00:01:28,710
we'll do the same thing to make R2-D2 move
down.

17
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

18
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

19
00:01:40,810 --> 00:01:42,510
more interactive.
