(Janet - Zynga Engineer) 
Anyone can be a programmer.

2
00:00:01,500 --> 00:00:03,600
You just have to be a little bit adventurous,

3
00:00:03,600 --> 00:00:07,200
be willing to learn, and have a great idea.

4
00:00:07,200 --> 00:00:10,000
To explain functions and parameters,

5
00:00:10,000 --> 00:00:13,500
I can use the example of when you order food for lunch.

6
00:00:13,500 --> 00:00:16,000
So say you're ordering a sandwich and a drink.

7
00:00:16,000 --> 00:00:19,000
Well, the parameters would be

8
00:00:19,000 --> 00:00:23,000
what flavor of drink you want and what size sandwich do you want.

9
00:00:23,000 --> 00:00:25,000
And so in this way,

10
00:00:25,000 --> 00:00:28,320
functions in computers take parameters so that

11
00:00:28,320 --> 00:00:32,270
you can specify how big a shape is

12
00:00:32,270 --> 00:00:35,000
or what color the shape is.

13
00:00:35,000 --> 00:00:37,600
What if we want to draw a bunch of triangles and have

14
00:00:37,600 --> 00:00:39,230
their lengths be different sizes?

15
00:00:39,230 --> 00:00:43,000
Now you can use our function block and input different numbers

16
00:00:43,000 --> 00:00:45,000
so that we can draw different sized shapes.

17
00:00:45,000 --> 00:00:48,000
If you click the star on the draw triangle function,

18
00:00:48,000 --> 00:00:51,000
you can drag input name into input block;

19
00:00:51,000 --> 00:00:52,800
and then if you write

20
00:00:52,800 --> 00:00:56,129
length in the spot where it says X and press Enter.

21
00:00:56,129 --> 00:00:59,000
You'll create a length input for your function.

22
00:00:59,000 --> 00:01:02,000
Then click on the star again to close it out.

23
00:01:02,000 --> 00:01:06,000
Now, you'll want to click on the variables category

24
00:01:06,000 --> 00:01:10,260
and drag the length block into the move
forward block of your function definition.

25
00:01:10,260 --> 00:01:14,750
Drag away the old number block and now
you have a function block

26
00:01:14,750 --> 00:01:18,000
where you can input the length of the sides of your triangle.

27
00:01:18,000 --> 00:01:20,500
This is called a function with parameters.

28
00:01:20,500 --> 00:01:24,000
To use it, click on the functions category

29
00:01:24,000 --> 00:01:27,220
and drag out your draw triangle with length function.

30
00:01:27,220 --> 00:01:30,500
Now you can use the math block to input different numbers

31
00:01:30,500 --> 00:01:33,000
to draw triangles of different sizes.

32
00:01:33,000 --> 00:01:35,300
Give it a try in soon you'll be a coding ninja.
