Hi sparks, I was wonderring if you could help me make a random block generator.  What it would do is find a block on the Local block library, and display it.  All credit would be given of course, but is it doable?

Well this will work: You just take the current block download code and set t1 to a random variable at the start:

Code:

download random block from the block library

Code:

|maker link t1 t2 t3 t4|
t1_ self randomFrom: 1 to: 59.
link_'http://dl.dropbox.com/u/6273449/', t1 asString, '.txt'.
maker_self readLine: 1 FromUrl: link.
t1_self readLine: 2 FromUrl: link.
t2_self readLine: 3 FromUrl: link.
t4_self readLine: 4 FromUrl: link.
t4_self stringAsColor: t4.
t3_self readLine: 5 FromUrl: link.

createdBlocks at: t1 put: {t1. t1. '-'. ''. self class blockColorFor: 'custom'}.createdBlocks at: t1 put: {t1. t1. t2. t3. t4}.(t4 _ self ownerThatIsA: ScratchFrameMorph) ifNotNil: [t4 viewerPane categoryChanged: 'variables'].

self showInformDialog: 'Sucess!' withText: 'The block has been added to your variables tab.', '
', 'The "', t1, '" block', '
', ' was shared by ', maker

note the "t1_ self randomFrom: 1 to: 59." on line two of the code! The only problem with this is that when more blocks are added to the library they will not be shown by this block unless you change the 59 to a new number. It might be possible to increment a counter until trying to read a block returns an error page but I'll leave you to research that!

But it's not to download     It's to show on the page [url]www.cyberkidscountry.com/s360.html[/img]  where it should show code & the ('Block code thing' #-) as well as an image.      So I need to use JS or html/css

... I realise I may have misunderstood. Did you want this to display a block from the library using php on a webpage?

Yes.  That's exactly what I want to do!  It should show, code ('This thing' #- #-) and an image!   

Hmm.... I'm not certain how to read lines from other webpages into php variables... I've never needed to do that... But as Scimonster says above, you can use TheSucessor's block generator to display the image!

Get the source of the block lib page, and find the spec, code, and image. 

I don't know PHP (yet), so: idk.

I have a new block...

Blockspec
('stop all scripts for %m' #- #stopAllScriptsFor: 'Stage')

Code:

stopAllScriptsFor: t1 
t1 stopAllMine

You first have to make the code that TheSuccessor made. e.g.

Code:

stopAllMine
    self scripts do: [:t1 | t1 stop]

I don't have time to add it plus it might be better if we just save up blocks for a bigger update than just 1 block. 

I think you might have to do this instead for the method:

Code:

stopAllScriptsFor: t1
(self coerceSpriteArg: t1) stopAllMine

The sprite name could be a string, so we have to use coerceSpriteArg: to make it a sprite.

Without my block, just do this:

Code:

stopAllScriptsFor: t1
(self coerceSpriteArg: t1) scripts do: [:t1 | t1 stop]

I didn't think of that. XD Thanks.

Scratch, BYOB, or Panther blocks?

Scratch, I think. (The open URL block)

TuragaTreeko, you need quotes around strings for default values.

you wrote:

blockspecs: ('open "my stuff" page for Scratch user %s' #- #doOpenForUser: scimonster)

ops: openForUser: t1
    cursor wait showWhile ScratchPlugin primOpen URL: http://scratch.mit.edu/users/ t1

This won't work. You need:
blockspecs: ('open "my stuff" page for Scratch user %s' #- #OpenUser: 'scimonster')

ops:
openUser: t1
    Cursor wait showWhile: [ScratchPlugin primOpenURL: 'http://scratch.mit.edu/users/' , t1]

Haha, woops. I guess that wasn't as good as I hoped it would be. I'm not all that good at this. But I WILL keep trying! I'm determined.



did you notice I used you as the default value? 

Once you get better you wont make as many mistakes.    But notice I said, "as many"    I make a lot of mistakes still. XD I just recently compleatly forgot to put 'self' before commands for a whole script I was making.       You may not make as many mistakes as I do.
