the Byte Smalltalk issue, way back when

Oh hey, you're a Smalltalker! I can never resist old dudes who know Smalltalk(odwks). 

So, here's how you can access Squeak from within BYOB: Start BYOB with "dev" (sans quotation marks) somewhere in the command line (a Windows batch file or a shell script). Afterwards you can shift-click on the "Edit" Menu to get the developer's options. Personally I use a little batch file:

                  start BYOB.exe BYOB.image dev

if you want to be able to drop projects on this icon you might want to add a %1 to that.

If you do it like that you're still missing variable names and code comments in Squeak. Those are in the .changes and the .sources files. So, if you also want the .changes file (before the official release in August, which will include it anyway), just holler and I'll add you to our BYOB-alpha mailing list, which will give you access to it whenever I release a new version (which is often    )

I just had a go at that dev start up, but it didn't work, it opened it up, but If i shift-click the edit menu, I don't get extra options.    Im using BYOB 2.99.015

Edit: I put it in the wrong folder, sorry, I have BYOB 2.0 and 2.99.

Nah.  Enjoy.

the Byte Smalltalk issue

Ah, someone else my age! 

Where in the UK are you?  There is a possibility of
my being in London around the first week of Aug.

Well, I live and work in the north-west (Southport, north of Liverpool), but I'm afraid I'm on holiday then in Wales.

I would love to be on the BYOB-alpha mailing list. Do you have my email address?

We now have help screens for the new-in-BYOB blocks (except DEBUG, for which I'm waiting until I'm sure the user interface has settled down).  Unzip the archive and copy the files from the resulting folder into {byob-folder}/Help/en.  There will be one expected conflict with an existing file; say yes.

Yeah, I know these are more crowded than the Scratch ones.  Suggestions for improvement are very welcome, especially in the form of picture files! 

P.S.  Also welcome are translations into other languages.

Ok, sorry, I was calling the savedPosition reporter again rather than the variable into which I'd saved the result of the savedPosition reporter! Twit!

I've been playing around with the idea of saving and restoring a sprite's position in a functional way. So I defined a reporter called savedPosition that returns a script which does a goto x:y: on the saved position.

It works with the following "process"
Your savedPosition is defined as Motion+reporter
You report into the report window a script C-Shape containing instructions :
goto x :x
point to direction: direction

To save the position you set this function to a variable save-pos with :
     SET save-pos to savedPosition
To recall the saved position :
     RUN saved-pos
Then move the sprite to another position.
    Reset save-pos with SET
    RUN saved-pos again, the sprite returns to the saved position.

(to move a sprite with the mouse, unlock it )

@ bharvey & Jens

I've finished my first tutorial game, written in Byob, and the same one in Scratch. I'm to make comparisons of performance between both.

see : http://www.xleroy.net/ByobTuto/thumbnails.html

As far as programming process is concerned, there is no major difference for this type of application. The Scratch couple of "broadcast/when broadcast received do so and so" allows a turn-around of lack of functions (in order to avoid to rewrite several times the same flow of instructions for the same action). And, even with Byob primitives you need to use these "multi-process" features.

All put together, Byob allows all applications that Scratch can do, where Scratch is more limited for scientific applications like maths, physics, computer science.

In my humble opinion the innovative approach of Byob in the ways of doing programming today, fits well with the revolutionary concept of Scratch.  Combination of both opens an immense field for imagination, creativity, experience sharing, "programming for all" ...

Thanks, this is awesome!

I just started Scratch up and BYOB. Then I connected two programs using MESH (I was just experimenting.) I did'nt think it would work even though their based on eachother and have different file extensions but it does and I have proof:

Yes, both BYOB and Scratch still work together nicely over the mesh, because currently the only feature added by BYOB is being able to share sprites over the mesh. Oh, and of course you can also use the Picoboard and the LEGO WeDo kits with BYOB

@Jens how to share sprites over mesh?

When you've connect several BYOB sessions right clicking on a sprite gives you the option to "share this sprite". This will copy the sprite including all of its resources and scripts to every other BYOB mesh participants.

Oh, you mean how is it implemented? It serializes the sprite (same as when it is written to a file) and sends it over the mesh using a specialized prefix, so the other participants know how to parse it. Is that what you wanted to know?

Another glitch:

http://scratchx.webs.com/

can someone get this website on the first post? I re-made my website and (i'm still working on it now) for BYOB.
