BYOB 2.99.009 now at http://byob.berkeley.edu, fixes a bug about nested lambdas with explicit parameters (important for the Church numerals project; one of my high school students reported the bug this morning).

Another functional programming project, easier than Church numerals, is blackjack (21) strategies. Download writeup and skeleton project at http://byob.berkeley.edu.

I've noticed that Mesh is not working, I'm not sure if anyone has mentioned it, but thought I might let you know...

Fixed. The problem was in the Squeak VM included in BYOB.exe on Windows. You can download just BYOB.exe and put it in the same folder as the rest of the distribution, probably \Program Files\BYOB. Or download a complete installer if you'd rather.

Anybody in the Bay Area next week is invited to a BYOB sneak preview on Scratch Day. People reading this forum already have the software--this isn't an unveiling of a new release--but it'd be a chance to get together. I'm hoping to attract people who don't read this forum via the Scratch Day web site.

I wish I could travel half the country for this. It sounds cool! Maybe you could post a summary of it?

Don't worry, usually on scratch day there are tons of posts on the forums about what diferent people saw.

BYOB 3 sounds like a great interpretation of scratch but, I liked the old system of building your own blocks on BYOB 2 more than it looks like on the alpha version. But in the end, it's still more advanced which is the aim of BYOB.

Ah, you're the other American. smile

There isn't really going to be anything to summarize; people are going to come and play with BYOB and meet each other and maybe we can get a local community going. Nobody has signed up yet, though. sad

If you live somewhere on I-80/90 I could visit you when I drive to Boston next month. smile

I found a glitch! In the block editor you can duplicate the custom block embedded into the hat block!

How? When I try it, I get the "change category" menu.

If you click the scissors and then hover over that block, you get a red rectangle around it, but you can't actually cut the block. smile

PS Was I right? Did you like the Church numerals project?

achinn · 2010-05-14 14:50:39

Is there a way to change a block from a command to a reporter after it has been created?

No! I want that too. You can change its color/menu by clicking on the hat block in the block editor, but Jens says it's harder to change its range. But I'll twist his arm before the official release, I promise. smile

Yeah, i really want that, sometimes when im trying to do something but i made the block the wrong shape. It gets really annoying.

Ok, I was trying to create a script that runs other scripts simutaniously. But it wasn't working.

First i made this:

With this code:

That didn't work so i tried this:

With this code:

That didn't work either!

What am I doing wrong?

That is because you cannot 'launch' a list...
If you wanted to launch them in separate threads, you could use an atomic repeat loop to 'launch' each item of the list

Right click on the very edge of the block.

I haven't really looked at the Church numerals project yet. I'll have to do that... smile

Hmm. I still can't reproduce this, but I'll just leave it for Jens to worry about when he gets back. smile

Oh, it doesn't work with command blocks. Try it with a reporter!

Ah. Right you are. That's funny! smile I wonder why commands and reporters behave differently about this.
Thanks.

When everyone finishes playing with Panther, stop by http://byob.berkeley.edu for 2.99.010. fixing a few bugs including MathWizz's duplicating prototype, and also providing the framework for localization support (for which there is another folder of files besides the image). There's an example German translation; native speakers of other languages please contribute more!

So when are you expecting a full BYOB 3 release? I know there are still some bugs to be dealt with, but most of the major ones are gone...

Word on the street is late summer, around the time of Scratch@MIT.

There are still missing features, like the localization stuff Jens just put in. At the top of our list are debugging support and speed, both of which are essential if anyone other than hard core early adopters like you guys are going to use it! After that, if there's still time before August, we'll start in on "first class everything": sprites, costumes, sounds, colors ( smile ), macros, continuations, ... (Well probably not really those last two; that was a Scheme in-joke.) But the basic plan is to keep going full speed ahead until right before the Scratch conference.

(EDIT) Some time between now and then, I guess we'll get confident enough to start calling it "beta" instead of "alpha"! smile
