Scratch

I have no idea how to code in Squeak. 

showMenu: t1 
    | t2 t3 t4 t5 t6 t7 |
    t2 _ self listNamed: t1 ifNone: [^ ''].
    t3 _ self lineCountOfList: t2.
    t4 _ 1.
    t5 _ CustomMenu new.
    t3
        timesRepeat: 
            [t6 _ self getLine: t4 ofList: t2.
            t5 add: t6 asString action: t6.
            t4 _ t4 + 1].
    t5 localize.
    t7 _ t5 startUp.
    ^ t7

This takes the name of a list as an argument and displays a menu containing the items in the list. However, the menu never displays and it just reports nil. Can anybody fix it?

   ^ false

I think this would work but as I haven't tried it I don't know.

I would try

spriteExists: n
((ScriptableScratchMorph, ScriptableScratchMorph allSubClasses) collect: [:c | c allInstances]) do: [:m | m objName = n ifTrue: [^ true]].
   ^ false

Whats the block spec?
<when green flag clicked>
<go to[ my profile
<forever>
<play sound[ come to my profile!
<change{ users who went to my profile }by(1
<end>

It says Error

I got it to work with

spriteExists: n
ScratchSpriteMorph allInstancesDo: [:m | m objName = n ifTrue: [^ true]].
   ^ false

Thank you for the help. How would I make a block that adds a costume to a sprite from a costume block that reports a costume?

You deleted the thing I purposely added. You got it wrong:

Code:

spriteExists: n
(({ScriptableScratchMorph}, ScriptableScratchMorph allSubclasses) collect: [:c | c allInstances]) do: [:m | m objName = n ifTrue: [^ true]].
   ^ false

The code before worked perfect, but your code is in the way, tricking scratchers to use the wrong code.

Um, how do you plan on setting a reporter to a picture?

Just modifying the preview, it doesn't care what the return value is.
Warning: costumes are not Forms.

That's why I got so many errors with mine...

Now I'm trying to make a block that takes a reporter block for an image and makes that into a costume and adds it to the sprite. Can anyone help?

that's actually a really good idea - i looked over that post not thinking it important, but now that i get what you're trying to do it's very interesting. tat could be something to work on for Bingo 1.2.1...

I already have the costume reporters, now I'm trying to make an [add [ '' ] to costumes] block. [ '' ] is the costume slot representation.

sensor yellowButtonPressed or blueButtonPressed doesn't work for me

Why not just make reporters which report costumes?

I already have. BYOB made that easy. Now I need to have it add these to costumes. I'll post a secret 1.1 beta to help explain. http://dl.dropbox.com/u/6509165/Slash%2 … Beta.image Look at blocks such as 'self'.

No, I'm saying, you don't NEED a new block shape, just use old-fashioned reporters.

i had a look at Slash 1.1 Beta and it's got loads of blocks copied from Bingo. too bad mostof those you added dont work 
but please code the cursor one yourself.

Very secret now, isn't it...
