You enter the name of you new block and then drag blocks from the palette into the block editor. Check out the examples and tutorials, too. There are lots of them 

Build Your Own Blocks -- With other blocks 

It's quite complicated, but I love it 

ive made a login block with the v2.29 version of byob
but the offical block will be out on my site soon.

One little programming detail:  There's no need to say

LAUNCH ...
STOP BLOCK

That combination is exactly equivalent to RUN ... .

Oh, P.S., real security mavens say that you shouldn't tell people which of username and password didn't work; instead collect both of them and either accept or deny them as a unit. 

EDIT:  I'm sorry, not "exactly equivalent," but exactly equivalent as you've used them, where the block is going to stop anyway because there's nothing left to do after the IF/ELSE.  I should have said that LAUNCH+STOP is the same as RUN+STOP.

Can you export your blocks into normal Scratch, or save them so that you can use them with any project?

how to you get byob blocks into scratch

Please give us a specific example that doesn't work, and what response you get when you try it.

Or you can report bugs directly at http://byobugs.com.

It's ALL the examples, and there is no scripts.

Is there any simple squeak/smalltalk I could use to implement new block names for existing blocks through the 1.4 source code?

yeah there is.

Turn fill screen off, open a browser, and go to Scratch-Objects>ScriptableScratchMorph (make sure you have 'class' selected)>block specs>blockSpecs, and change block names there. Here is how to do that:

you will see a lot of things that look like: ('bla bla bla' #- #blaBlaBla). let's take the |wait (1) secs| block for example. Find this: ('wait %n secs' #- #duration:elapsed:from: 1) change the 'wait %n secs' to whatever you want, just keep the %n. For example change it to 'delay %n' and the block will now look like |delay (1)|. If you need additional information (call this toll free number ......... just joking) click this smiley:

Oh. Sorry, I was in a hurry, here's a better tutorial:

Jens and I are extremely pleased to announce (finally!) the release of BYOB 2.995 beta.  You can download the Macintosh and Windows files-only version (just put it in /Applications on a Mac) or the Windows installer.  You should download the complete package even if you already have BYOB, because of changes to the manual, the help files, the compiler, the dev access, etc.

Jens wrote:

Windows installer: It's best not to select the default folder offered by the installer (C:\program files\BYOB) but to select some other folder that is not a subfolder of Vista's paranoid UAC system. BYOB will run fine from C:\program files\BYOB, but editing the source code and trying to open Elements may lead to strange, Vista-related error messages. These don't happen if you select another folder.

One major change since the last alpha:  By popular demand, BYOB now has special forms.  This means that you can declare a block input slot to be of type "Any (unevaluated)" or "Boolean (unevaluated)"; these inputs look to the block's caller like Any or Boolean, but actually behave like Reporter or Predicate respectively -- the expression you drag onto that input isn't shown with a grey border, but in fact BYOB puts an invisible THE BLOCK around it.  The first and most important application is in tools.ypr 1.6, in which the reporter IF/THEN/ELSE block is intuitively usable by someone who doesn't know anything about procedures as data.  This also means we can explain the behavior of the Scratch looping and conditional blocks' hexagonal input slots with the truth: They are of type Boolean (unevaluated), not of type Predicate.  (You'll remember that this was a point of confusion for several alpha users!)  The shapes and colors of the input slot types have been changed to reflect this new story.



Also new in this release: the "compile" option works on the Macintosh as well as on Windows.

Finally, in the folder are files named "BYOB development.sh" (Mac) and "BYOB development.bat" (Win) that can be double-clicked to open BYOB in developer mode.  Shift-click the Edit menu to get access to the Smalltalk browser and the full source, comments and all.

Many. many thanks to all of you who've helped us get this far.  There are still bugs and missing features, but it's in so much better shape than 2.99.000 because of your contributions!

I'm trying to use the .changes file to add BYOB to Slash, but I can't. Can anyone help?

Note: if you try, download the .image as of now, I just updated it.

Update: I've made a bit of progress, but it's hard. Does anyone have advice?

Hi Billybob-Mario,

it's great that you're trying to incorporate BYOB in your Scratch mod! That's exactly why we made it easy to switch into development mode. Unfortunately, it's not just importing a file (like the .changes file) that will make it work. Also, the comments shouldn't be the problem. What you need is the changesets in their correct order. But these aren't really  well kept in BYOB, because mostly I've been hacking away under great time pressure, often switching back and forth between changesets, and sometimes not creating new ones when I should have. Also, BYOB fundamentally changes almost everything internal in Scratch, even the most simply code like moving a Sprite forward by 10 steps, because of the nested sprites feature. Therefore my advice would be to do it the other way round: Why not file out your changes file them into BYOB and make the adjustments you need. I'm pretty sure that this would be way easier and might just work.

Good luck!
