Easy! To define a block, just do this:

SAMPLE BLOCK:

when this sprite clicked
WALK

DEFINE WALK
glide (1) secs to x: (120) y: (180)

In defining a block, use the desinged-by-scratch blocks and put them under the define block. So here, when a certain sprite is clicked, it will WALK(walk being the custome block), thus, doing what the define block says. Understand? Do you have any questions about inputs like strings and numbers? If so, ask me! I'm not very good with booleans though…

Take this for example:

when I receive [scratch.mit.edu v]
forever
    imagine
program
share
end

define imagine
set [Ideas v] to [INFINITY]

define program
set [YOUR AMAZING ABILITYS v] to [INFINITY]

define share
set [YOUR AWESOMENESS v] to [INFINITY]

for example, you are that sprite. When scratch.mit.edu is roadcasted, you will imagine, program, and share. When you imagine, you set ideas to infinity. When you program, you set your amazing ability to infinity. When you share, you set your awesomness to infinity. So, the definition blocks tell that block what to do. To define a block, basically, put designed-by-scratch blocks into it. For example, if you want a sprite to talk when the green flag is clicked, make a block called talk. Then in define talk, put what you want it to do. If you want it to say hello, put say hello! for () seconds under define talk. Get it?

Click “Make a Block” in the “More Blocks” palette.

Dont understand? To define a block, put blocks into it that show what the block will do. like this:

define WALK
point in direction (90 v)
move (10) steps

Thats a block definition. You can only use blocks made by scratch to define a block. If you want the sprite to say something, define a block like this:

define TALK
say [(something)] for (2) secs

Basically, just define a block by putting blocks under it, what you want it to do.

forever
    imagine
program
share
end

U can also do blocks with input such as these:

define Hi (Number)
move (Number) steps

Hope this helped!

making a block is simple. whatever i put under the define block, happens when I use the block I made.

You can make blocks like this:

define walk
glide (1) secs to x: (0) y: (0)

//trigger here
walk

Or, you could also make blocks with inputs:

define setLoc (number) (number2)
go to x: (number) y: (number2)

//trigger here
setLoc (0) (0)

what if you need to put in a starting block in

define 
when [ v] key pressed
when [v v] key pressed
define 
when [ v] key pressed
when [







 v] key pressed

Please create your own topic rather than necroposting.

Using “More Blocks” can also define sprites.

when green flag clicked
(Name)

define Name
move (10) steps

This is how:
First when you make a block

Think Hard []

a

define Think Hard [Think]

will appear. You can then use it like this:

define Think Hard [Think]
repeat (3)
think [fwd] for (.01) secs
think [GCC] for (.01) secs
think [bf] for (.01) secs
think [gs] for (.01) secs
end
think [!] for (.) secs
think (Think) for ((length of (Think)) / (2)) secs

Note: the block will use the inputs given in the code.

You should create your own new topic and share your project so we can better understand your problem.

PlayerXS

Defining a block is when you place the block, it tells what it means. On the hat block, which is "Define ", you can put scripts under it, and that tells what that block means.
Ex:

When flag clicked
move 7 steps
define move 7 steps
move (7) steps

now, that purple block, “move 7 steps” has a definition. When you use the block, it will move 7 steps, because that's what we put under the

define

block. Get it now?
