1
00:00:00,000 --> 00:00:05,440
What if we want to perform the same sequence of code, execute the same procedure each time the

2
00:00:05,440 --> 00:00:10,880
custom block is called in the main program, but each time we want to make small changes,

3
00:00:10,880 --> 00:00:16,559
like the text shown, or the coordinate used, or adjust the value in one or more of these blocks?

4
00:00:17,120 --> 00:00:21,920
Let's learn how to create a MyBlock block that can be customized each time it is used.

5
00:00:22,559 --> 00:00:26,399
Let's start by setting up a custom block that has the character speak and say

6
00:00:26,399 --> 00:00:32,640
certain text at the same time you'll see the code stack i want to use here i'll click the mega block

7
00:00:32,640 --> 00:00:38,159
and give it a descriptive name as before like speak and say but since i want to customize the

8
00:00:38,159 --> 00:00:44,320
text my sprite will speak and say each time i'm also going to add an input with an input in place

9
00:00:44,320 --> 00:00:50,159
the custom block will use the parameter the data i provide in the input bubble when i use the block

10
00:00:50,159 --> 00:00:55,719
block. In this case, the input I'm choosing is number or text, and so I remember what

11
00:00:55,719 --> 00:01:00,960
the input is, I also want to give it a descriptive name, like, what to say.

12
00:01:00,960 --> 00:01:06,439
Back in my scripts area, I'll add the desired code sequence under the define block. Then,

13
00:01:06,439 --> 00:01:11,400
in place of static, unchanging text in the speak and say blocks, I want to use the input

14
00:01:11,400 --> 00:01:13,659
I created while creating my block.

15
00:01:13,659 --> 00:01:18,099
To get the input, click on the input label in the define block, and drag it out to place

16
00:01:18,099 --> 00:01:19,879
it in a code block.

17
00:01:19,879 --> 00:01:24,659
In this case, I want to use the same text in both the speak and say blocks, so I'll

18
00:01:24,659 --> 00:01:25,659
do that two times.

19
00:01:25,659 --> 00:01:30,400
Now, when I use this custom block in my main program, you can see the blank input bubble

20
00:01:30,400 --> 00:01:34,280
where I can enter the parameter, in this case my custom text.

21
00:01:34,280 --> 00:01:36,340
Let's run the code to see how it looks.

22
00:01:36,340 --> 00:01:38,439
Hi, I'm a dragon.

23
00:01:38,439 --> 00:01:39,739
I have hot breath.

24
00:01:39,739 --> 00:01:44,459
I'm able to use the same code sequence and customize it over and over without rewriting

25
00:01:44,459 --> 00:01:46,400
this code stack each time.

26
00:01:46,400 --> 00:01:54,159
If I need to make edits to the procedure, I only need to make changes under the Define block to update everywhere the block is used in my main program.

27
00:01:54,159 --> 00:01:58,000
Hi, I'm a dragon. I have hot breath.

28
00:01:58,000 --> 00:02:03,799
Let's see another example where I want to customize the X and Y coordinate every time I run my custom block.

29
00:02:03,799 --> 00:02:12,180
As I create my custom block, I can add labels between inputs to help me remember what is what as I use the block and fill in the parameters.
