Scratch

@Jens&bharvey

Another point (it is probably more a question of definition than a bug...)
With Byob 2.99.024

LENGTH of xposition (=84) gives 2
SET txt to xposition
SAY txt gives 84

But ...
LENGTH of txt gives NIL

This issue does not exist in Scratch which gives 4 for LENGTH -184

whn does it come out?

It's sort of out now, in alpha test, at http://byob.berkeley.edu.  Official beta pretty soon, after we clean up some bugs.  Official 3.0 release in time for the Scratch conference mid-August.

I made a 'hacked BYOB' mod, which is BYOB with the developer menu. Click the red dot on the logo to open it. Download at sites.google.com/site/slashproj/downloads

As Jens has posted more than once, you can get a dev menu in any recent BYOB image by starting it with

[Mac] BYOB.app/Contents/MacOS/BYOB BYOB.image foo.ypr dev

[Win] start BYOB.exe BYOB.image foo.ypr dev

and then shift-click the Edit menu.  (It took me a while to get this to work because, at least on the Mac, the project filename isn't optional, even if there is no such project file.    )

There's nothing evil about you making your own version that starts with a dev menu, but I'm a little nervous that people who use it will get stuck with an old version; Jens has been issuing new BYOB.image releases pretty much daily, with lots of bugs fixed.

But it’s far from straightforward and it doesn’t look like the mockup at all - it’s ugly xD Any idea on how to improve 

Yeah, that's where Jens and I were, too, until nXIII gave us a brilliant solution, which is to include one "case" value and one command script as inputs to a reporter block that would report true if the case was satisfied, false otherwise.  We generalized this to have the reporter take a predicate as the first input so it could ask any question about the given value, e.g., is it a vowel, etc.  The result is the SWITCH block and its friend the SWITCH.CASE block in tools.ypr.

Also, theres an extremely annoying bug, every time I drag the block around, add some parameter, whatever, it becomes about 5 pixels wider.

Wider left-to-right?  We know about blocks getting taller sometimes and that's supposed to be fixed about two releases ago.  Could you please take before-and-after screenshots and upload them to http:byobugs.com?  Thanks!

Oh - I was using 2.99.000; let me update my post with the .007 image ;D

You should get the 007 release and then you should replace its BYOB.image with the latest one!  We've been dilatory about declaring anything past 007 "stable" (partly because each new release is so much less buggy than the one before with no plateau in sight) but 025 is in fact way more stable than 007.

We'll take a day off from debugging soon and put together complete packages with installers and the new helpscreens and everything.

I really like byob, but my biggest issue is the lag

Yeah, we hate that, too.  We're working on it, but still just finding out where the slowdowns are.  It's our highest priority between now and August.

BYOB should run exactly like Scratch with a huge speed-up if you use atomic custom blocks.

Except on my projects.     One slow thing we know about is using lists in recursive functions.  Stay tuned.

But sometimes you don't always want atomic blocks, maybe add an atomic checkbox to certain blocks?

hey! has anyone come up with a block that maps out a variable's coordinates? That would be EXTREMELY helpful. Thanks!

I don't understand what you're asking for.  In what sense does a variable have coordinates?  Or are you thinking about a particular kind of value in a variable?

I think markyparky56 wants to run some blocks in a script atomically, and others not, without having to make a special block for this kind of "speed control" within a script. And you can do this in BYOB by right-clicking on the THE SCRIPT or THE BLOCK block and selecting the "atomic" checkbox.

Try this:

   WHEN space PRESSED
   RUN THE SCRIPT [
      REPEAT 180
         TURN 1 DEGREES ]

with the THE SCRIPT's atomic checkbox marked and unmarked, and enjoy the difference!

This will in effect make the REPEAT block run atomically, and it can be some with any other script as well (except for scripts containing timed blocks, of course)

I use a slightly different code for the dev options.

start BYOB.exe BYOB.image dev
