Scratch

Hello! I decided to make a page talking about all the scratch bricks and how to make them. I find a lot of people are struggling with it! For your information, all Scratch blocks online will look boxey. First of all, type [scratchblocks-] (remove the -) to make the forum know that you are typing scratch blocks. Always place a block on another line! (press enter before you try and type another brick) To insert a stack block ( the rectangular ones with TWO bumps ), you simply type the text you see. For the white spaces you see in the brick, or the numbers or letters you can change, you either place brackets () or a box [] in it. It depends on the shape. ( It really does not matter if you use () or [], but the () one makes the background white and the [] will make the background color the same as the brick's color.) For example, if you want to add a wait brick to forum, type this:

Preview:

wait (1) secs

If you look closely, you see a ending command ( [/scratchblock]). This is to make the forum know that you are ending making bricks. If you want to change a set variable brick, do this:

Preview:

set [variablename v] to [1]

The v beside "variablename" is the little arrow in Scratch that is used to scroll down a list of variables. Remember to put a space between the variable name and the v. Some bricks, like the turn brick, has a picture in it. To type the clockwise and counterclockwise, we replace the picture with cw or ccw. The counterclockwise brick is ccw and the clockwise is cw.

Produces:

turn cw (15) degrees

and

Produces:

turn ccw (15) degrees

. Some bricks only have one bump on it. They are either ending bricks ( Stop script and Stop all ) or "Hats", the bricks that have a curved top. To make a ending brick, copy the text on it.

Makes:

stop all

. Making hats are also like making ending blocks, but the start green flag hat has a picture. Replace Green Flag Picture with gf.

when gf clicked

. The other hats are easy to make. Some hats, however, has a block for selecting variables. Remember to place a "v" in them.

when [space v] key pressed

. Now for the blocks called "c-shaped"! These bricks are the blocks like "forever, repeat, if..." To make them, you do the same for all the bricks, copy the text, make some variable boxes. After that, place bricks that you want in the "c-shaped". To make sure that the forum knows that you are done adding things into the brick, add an "end" command.

repeat until <(variable) = [2]> 
say [Hello world!] for [1] secs
end

. The <> is there because if you place the [] = [] block ( all bricks that are diamond shape like [] < [], <> and <> bricks are called a Boolean brick) into the repeat until block, it looks like a diamond shape. The variable is a () shape, so you see variable in a () shape. The number 2 is in the second box on the Boolean brick, and if you place a number into a boolean, the shape ofthe box stays the same, so you place the number (in this case, 2) into a [] box. The if..else block has two "c-shapes", to make it, you do the same for a regular "c-shaped' block. Don't forget to add the end command.

if < (variable) > [1] >
say [Win!] for (2) secs
else 
say [Lose.] for (2) secs
end

For multiple "c-shaped" bricks, do the same thing.

Creates:

when gf clicked
repeat until < (variable) = [2] >
say [Hello world!] for (2) secs
set [variable v] to (pick random (1) to (2))
if < (variable) = [1] >
stop script
end 
say [Hi!] for (2) secs
end

To add color bricks, you will need to find the hex code of the color(s). Hex codes can be found here: Hex Code Link. Once you know the hex code, place it into the brick!

<color [#1ADB41] is touching [#FF9100]?>

Don't forget to add the number symbol (#) before you put in the hex code. To comment on bricks, use the // command.

move (1) steps // Is it too slow?

If you still do not know how to make a variable block at this point, it is very easy to make.

(variable)

. To add a white text block, do this:

[Hi!]

If you made an error, the forum will correct you by making the block red. For example:

wait (1) seconds

. Did you find what was wrong? Yes! Replace "seconds" with "secs". Fixed!
Thank you soo much for reading this! If there is something you want to know about Scratch Blocks, or if I made a mistake, please comment!
