Does anyone know how to use the code my blocks Idk how to create one

BPMGbest

I try to create a block in my blocks but Idk what it does or how to make it properly
I can't make it work

define

Met4Knight

basically, the my block thing lets you create a block by putting blocks in the definition section, here's an exemple

define jump (height)
repeat (height)
change y by (1)
end
repeat (height)
change y by (-1)
end

when green flag clicked
jump (10)

in this exemple, the height input takes the value that is in the input slot, that is, 10, so it will run the script under the hat block and every time that there is a height reporter in the script, the valye used will be 10

It can be used like a shortcut in order to not have to repeat long codes over and over again if you plan on using it several times.

So for instance if I want a character to do several things everytime I can make a custom block.
I can make a block called “Lava”, I have a game with lava in it in several different places, when my character touches the lava I want him to slide down, change x by 5 and say “Oh no”.

That block “Lava” holds all that code, so I can just insert “Lava” all the different times that I want my character to slide down, change x by 5 and say “Oh no” instead of repeating that code over and over.

So it's a way to keep things more tidy.
That's how I'd describe it, I haven't used it much though so someone else can correct me otherwise.

define ez
say [This is easy!] for (2) secs

when green flag clicked
ez

OK now I'm starting to understand but what does

Do you mean variables?

Variables work basically as memorization.

So if you do this,

set [my variable v] to [10]
move (my variable) steps

your sprite will move 10 steps.

if you're talking about parameters (the variables inside the custom blocks), here's an example of how they work:

move (5) // this sets the "amount" parameter to 5 when we run the block
define move (amount)
move (amount) steps // since we ran the block with a value of 5 in the "amount" parameter, it'll move 5 steps

Here is my explanation:
Custom blocks, besides being able to repeat scripts without having to copy and paste the, have a “Run without screen refresh” check box when creating it.
This is especially helpful when running the script all at once without it animating.

Once you get more advanced into real math classes, you'll see how they work. In a simple explanation, they store a data that can then be altered and manipulated.

I Do not understand properly bc I tried using the my blocks it doesn't really end up working

It was not doing anything properly it was doing the code but not when I press the green flag which is when it's supposed to activate I had to ‘see inside’ and click the code with

define

can you share an example project so i can see what's happening?

I made the project and the code is:

define jump(height)
move (10) steps
wait (1) secs
turn cw (15) degrees

The red jump that says height in orange below this is meant to be the my blocks code but I don't know how to put it as my blocks

The other part of the code was

when green flag clicked
jump(height)

The link for the project is: https://scratch.mit.edu/projects/1093308410/

your confusion is where the input should be placed…

jump (height ::custom) ::custom

is incorrect because we have not told the computer what “height” is.

basically the reporters pass a number through.

an easy example:

define set variable to (a) + (b)
set [example v] to ((a) + (b))

now if i run the code as follows:

set variable to (2) + (4) ::custom

it will set our example variable to 6, you are basically making filler values that you can replace later!
when you run that block, it replaces

set [example v] to ((a::custom) + (b::custom))

with

set [example v] to ((2) + (4))

why did it replace the ‘a’ with a 2? because you put a 2 in the ‘a’ slot!

basically a define block if a function. you can add inputs like so

define move(amount)
move (amount) steps

move 5 steps

this will move the sprite 5 blocks. you can change the value to anything. Also this is not the only place it is used.
