This is a great topic! I have a question though. I want to add motion blocks to the Stage . (mainly, the 'make %m move %n steps), but it always says "Stage selected: No motion blocks". How can I add motion blocks to the Stage?

Go to Scratch blocks ScriptableStageMorph class block specs blockspecs for the block then for the code jump to instance and go to other opp or whatever your block fits into (doesn't effect code but is for organizing use)
For Sprite only blocks go to Scratch blocks ScriptableSpriteMorph class block specs blockspecs for the block then for the code jump to instance
For both go to Scratch blocks ScriptableScratchMorph class block specs blockspecs for the block then for the code jump to instance

If you are talking about BYOB then you cannot make sprite only blocks but you can do for this sprite only.

Sparks, I am working on a code for making you able to not have to make all the blocks and so it would upload all the blocks from the block library! Could you help? We can make a website that will have only text saying ('name of a new block' #type of block #method) so that we can make it upload new blocks by reading the html of the website and putting it into a method something like

uploadingNewBlockSpecs
^ readContentsOfFileAtUrl: libraryscratchblocks.com

It would be a lot more complicated but thats what we can do. I don't know how we would make it read a method though.

Pecola is working on a way, to import every block in the block library, instead of having to edit the code

I cannot figure out how to do it quite yet but by making a website, and making the methods for the read file from url blocks, you could make Scratch read from the webpage (like the panther one) but instead you can make a block specs area like the obsoleteBlockSpecs and under blockSpecs by the self obsoleteBlockSpecs you could put websiteBlockSpecs which would read what is on the website and it would make those blocks go under block specs. The only thing is I cannot figure out how to make something make a method (like when you have the panther blocks make a method for them) If I knew how to do that then i could finish. So far i have for what the website would be like:

'control'
'show mouse cursor'
#-
#showCursor

Then under websiteBlockSpecs

websiteBlockSpecs
^( readLine: 1 fromUrl: whateverIwillNamethewebsite.com ( readLine: 2 fromUrl: whateverIwillNamethewebsite.com readLine: 3 fromUrl: whateverIwillNamethewebsite.com readLine: 3 fromUrl: whateverIwillNamethewebsite.com ) )

Could anyone help me? I am also doing this for RKT me ProgrammingFreak and ESN's mod.

Do you think you could use <sprite %m is %b> to report the action of another sprite?

possibly, I don't know the code

I have been working for a long time.
Blockspec:

('%B for %m' #b #getBooleanAttribute:of:)

Go to Scratch-blocks CommandBlockMorph all uncoloredArgMorphFor:
And add the strip:

$B = t2 ifTrue: [^ ChoiceArgMorph new getOptionsSelector: #booleanAttributeNames;
         choice: 'pen down?']

Heres the method:

getBooleanAttribute: t1 of: t2
    | t3 |
    t3 _ self coerceSpriteArg: t2.
    (t3 isKindOf: ScriptableScratchMorph)
        ifFalse: [^ false].
    'pen down?' localized = t1 ifTrue: [^ t3 penDown].
    'draggable?' localized = t1 ifTrue: [^ t3 draggable].
    'is a clone?' localized = t1 ifTrue: [^ t3 isClone].
    ^ false

Its weird that the simplest thing stopped me! Credit to rubiks_cube_guy238 for showing me I needed the
of: t2
    | t3 |
    t3 _ self coerceSpriteArg: t2.
    (t3 isKindOf: ScriptableScratchMorph)
        ifFalse: [^ false].

HELP!
I am still just working on the block specs

websiteBlockSpecs
^readFromUrl: https://dl-web.dropbox.com/get/websiteForLibraryUpload/websiteForLibraryUpload.txt?w=dd92f7e3

But it keeps saying

websiteBlockSpecs
^ Expression to return expected ->readFromUrl: https://dl-web.dropbox.com/get/websiteForLibraryUpload/websiteForLibraryUpload.txt?w=dd92f7e3

maybe it needs a ^ at the start??

It does have one

This blockspec could replace the old one: 

Code:

('%e received?' #b #eventReceivedNamed:)

this doesn't report error, but it always reports false... Please help 

Hmm... I think I kinda get what you're saying. Do you mean a block that reads it's blockspec from a website? Cos then an internet connection would always be needed to make them work. Or do you mean a patch that people can add to their copy of Scratch that allows them to add custom blocks to their projects easily?

I don't think something should add ALL the block library blocks at once to a copy of Scratch. What if you don't want some?

That code isn't new. You just took that right from Panther.

I have been working for a long time on it but it wont work.
Heres the code:

Code:

getBooleanAttribute: t1 
    | t2 |
    (vars includesKey: t1)
        ifTrue: [^ vars at: t1].
    t2 _ t1 localized.
    'pen down?' localized = t2 ifTrue: [^ self t1 penDown].
    'draggable?' localized = t2 ifTrue: [^ self t1 isDraggable].
    'is a clone?' localized = t2 ifTrue: [^ self t1 isClone].
    ^ false

it does not work yet.

Still cannot get this to work. It gets the attribute for a boolean. Like if its a clone pen is down or if its draggable.

Try this:

getBooleanAttribute: t1 of: t2
    | t3 |
    t3 _ self coerceSpriteArg: t2.
    (t3 isKindOf: ScriptableScratchMorph)
        ifFalse: [^ false].
    'pen down?' localized = t1 ifTrue: [^ t3 penDown].
    'draggable?' localized = t1 ifTrue: [^ t3 draggable].
    'is a clone?' localized = t1 ifTrue: [^ t3 isClone].
    ^ false

I thought about this and decided that I could make it just like panther has, the code could be more like when you click the button show library blocks it would ask you how many you wan't to show, you could say 'all' or the number you want. It would be simpler than I thought it would! I could add a global variable that would be websiteBlocksShowing
and then for the code i would need to make it... NVM this will be a challenge, but i was mainly making it for RKT so people don't have to always get the new version and the new blocks would update.

sparks asked me to repost these, so... yeah.'
