Scratch

Code:

('%b=%b' #b #a:equalsb:)

Code:

a:t1 equalsb:t2
t1 = t2 ifTrue [^true].
^false.

reports true if the two values are equal.

The fraction of block!

Image code:

Operators block.

blockSpecs code:

('%z of %n' #r #computeFraction:of: '1/2' #-)

Now you may not recognize computeFraction:of: or %z.

To get computeFraction:of: :

Go to Scratch-Blocks >> ScriptableScratchMorph >> other ops

And type in this code:

computeFractionOf: code

computeFraction: t1 of: t2
    '1/2' = t1 ifTrue: [^ t2 / 2].
    '1/3' = t1 ifTrue: [^ t2 / 3].
    '1/4' = t1 ifTrue: [^ t2 / 4].
    '1/5' = t1 ifTrue: [^ t2 / 5].
    '1/6' = t1 ifTrue: [^ t2 / 6].
    '1/7' = t1 ifTrue: [^ t2 / 7].
    '1/8' = t1 ifTrue: [^ t2 / 8].
    '1/9' = t1 ifTrue: [^ t2 / 9].
    '1/10' = t1 ifTrue: [^ t2 / 10].
    ^ 0

Then make this in ScriptableScratchMorph as well:

mathFractionNames code

mathFractionNames
    ^ #('1/2' '1/3' '1/4' '1/5' '1/6' '1/7' '1/8' '1/9' '1/10' )

To get %z:

Go to Scratch-Objects >> CommandBlockMorph >> -- all -- >> uncoloredArgMorphFor:

and type in this code:

uncoloredArgMorphFor: code

$z = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #mathFractionNames;
     choice: '1/2'].

And you'll have your fraction of block!

Man, I have no idea what you guys are saying with your scratch code. Could anyone help me with coming up with BYOB block?

And I'm over here, wishing that people would stop coming up with BYOB blocks, 'cause I'm getting overloaded with building the BYOB Block Library project. 

sparks, can you compile a list of BYOB blocks not in the project and provide easy access to them? 'Cause I'm, er, sorta behind 

I see you will not help me.    Already ahead of you, sparks.






^ By subzerostig


^ By me

Oh, and the hyperpaint blocks.

Just add those blocks to this

I have a Operator block for BYOB Here is the pictures:

I made a new block. It is below.
Scratch-objects> ScratchSpriteMorph> block specs> block specs:

('set rotation style to %r' #- #rotationStyleChange:)

Scratch-objects> ScratchSpriteMorph>motion ops

rotationStyleChange: t1 
    self rotationStyle: t1

Scratch objects> ScratchSpriteMorph>motion ops

rotationStyleChanger
    ^ #('normal' 'leftRight' 'none' )

Scratch-Blocks> CommandBlockMorph>> -- all -- > uncoleredArgMorphFor:
add the strip...

$r = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #rotationStyleChanger;
         choice: 'normal'].

and that’s it!

This is what it will look like:

[set word to( join (word in ascii code) (join [] (ascii code of letter (target) of (word) ) )
change target by [1]

I get confused with fourm blocks. Is this about what to mean?

If not is still makes a good block, and also makes case sensitive = block easy.

I cannot see the image because I have web blocks and they do not allow me to go to image shack. However I have changed the script to words.

You do notice that you can use the regular
[blocks]
<(       <=>      )>
[/blocks]
block don't you? You can drop booleans into it. like this:

[blocks]
<( <mouse down?> <=>  <loud?>    )>
[/blocks]

HI! Meowmeow55, I've had an idea that I would like to add to the library, but I'd like you hear your (and others') thoughts: Rather than having one big BYOB project containing all the custom blocks, which takes a while to download, and becomes useless once a new version is uploaded, leaving you with several instances of it on your computer, how about we remove the project and replace it with a downloadable sprite per block? I'm happy to help you convert the current project into sprites if you'd like to do it, then people can view the image or download a block, depending what they want? Let me know what you think, then we can split it up between us if you like the idea?

Here's a working example of what the BYOB section would look like:
-------------------------------------------------------------------------------------------------------------------------

A better download icon, I think, but you get the gist.

It may be possible to do this (or something very similar) for Panther blocks, in 1.0 and I'm hoping 1.1 will have a block importing button built in, but I don't think there's really a way for me to do it with a scratch block unless someone can think of a patch or something that would work...

ok, if SSBBM, meowmeow55 and I work together on that... should we host them all in one place? or do we all have our own file hosting places we can use?

shall we allocate ourselves for the moment to different block types so we don't upload two of the same? If you use my example .ypr file as the basis for the others, they can all look the same!

Can you please add my Scratch Block?

SSBBM, lets start that now then. If you want to do control I'll do motion, then we can use those two as trail ones, that I'll update to see if people like it. Then the others can follow 

I need a better "downoad" image...

I can't right now, but I'll get to it after I eat some pancake! 

Hi!

Great idea, sparks! I probably could become more organized that way. I could set a folder aside on my site for all the blocks, then have an option to either go directly to that folder from here to browse the blocks or browse them from the block library.

You could build off of nXIII's old patcher system for the blocks!
