I have an idea for a block: random number. It reports the most recent number chosen by the

you can just set a variable and do that

pick random (1) to (10)

, I mean.

Oh, you know what I mean.

My idea is faster.

but it would probably end up being more complicated trying to work with

How?

Because you can use multiple variables in the other method, here there is just one, which keeps getting reset, whereas a variable can be left alone, while a different one is set

It would be like the answer block.

ok, since I'm off ill I'll have a go...

I've got a list one!:
the blockspec is: ('list named %s' #r #contentsOfList: 'a list')
NO CODE

For me, I can just do this,

That won't work if the input is negative. Try 0-x.

What does 0-x mean? It worked for me.

It worked for you because you probably only used positive numbers, or numbers greater than 0. 0-x is a simple equation. 0 being the number, - being the integer (representing subtraction), and x being the variable, or the input.

I made a block:

ask for file with title [Choose a file] accepting extensions [txt doc]

Block Spec Code:

Code:

('ask for file with title %s accepting extension(s) %s'    #r #fileDlg:withExts: 'What file?' 'txt')

Actual code:

Code:

fileDlg: t1 withExts: t2     
    | t3 |
    t3 _ ScratchFileChooserDialog
        chooseExistingFileType: #any
        "extensions: (Array with: t2)"
        extensions: (t2 findTokens: ' ')
        title: t1.
    t3 = 'cancelled'
        ifTrue:[^ false]
        ifFalse:[^ t3].

Discussion over this block died (it's not in the library and I couldn't find anything telling me it was rejected), so I'm reposting it.

Like this?

((0) - (x))

No "join" block.

Like this:

Here's a cond block made in BYOB (remember to change the booleans the same amount as the actions!):

Example of usage:




Block code:



So yeah. Those who do scheme or lisp or stuff like that will know what cond is. Bacically, it's like a whole lot of if/else statements but it's a lot cleaner to look at.

Here's the set draggable block. (Another version)

Example:



if version:



cond version (using the cond block I posted 2 posts ago):
