Scratch

That's right. I mean the ones I do NOT define in the block editor. In huge projects I've long lists of instructions setting variables to zero. Sometimes it's very confusing  .

One question: is there 1.3.1 BYOB yet?

Thanks! I'm glad you guys like BYOB and grateful about all the feedback. The current version of BYOB is based on Scratch 1.3, so, apart from all the BYOB-bugs, there are still some "old" Scratch bugs in it.

this is what i want

This sounds interesting but can I access it on my Mac....it appears there is an .exe file.

Get a Mac .app file, and drag byob.image to it.

Hi Markyparky, I'm glad you like BYOB, thanks for giving it a try! How did I do it? I took the Scratch Source Code and started out with a mock-up of an editable block. Then I dug into Scratch's execution engine code and kept debugging the mock-up until it actually started working. The hardest part by far was getting recursion to work correctly (this nearly twisted my mind, lol!).

Hi ddakev, thanks for your interest in BYOB! Recursion in BYOB works this way: As soon as you define a block by entering a block spec a "template" is created in the pallette. You can then drag an instance of the template (your custom block) into the dialog box in which you define the script for the block, and pass along any variables or parameters. I've included some demo projects in the BYOB download which you can play with so to hopefully get the idea 

Yeah, that would be awesome. Combined with the ability to call the functions of other sprites or "broadcast to sprite", that would really open some doors.

Hi JSO, and all,

BYOB - and some other "wild idea prototypes" like Elements - are just my private experiments and not part of my 'real' contributions to Scratch (which are much less exciting). I'm very happy that so many people like BYOB and use it,and - as I stated elsewhere - I'm definitely planning to port BYOB to the Scratch 1.4 Source Code once that gets published, and maybe refine it some more. As far as I know, BYOB's features (procedures, paramater-passing, recursion, concurrency control) are currently not speed-tracked for inclusion in the official Scratch release.

ddakev - I recommend not to use discScratchr at the moment -  it is outdated and I believe only works with 1.3 projects or older. discScratchr and Scratch2Exe actually just run Scratch 1.3(.1) with a little modification that makes it open in full screen and closes itself when you exit presentation mode. So, since BYOB is a "different" version of scratch, it will not work.

Jens - Thanks for the reply! It's just that "BYOB" (or functions) is a mayor thing Scratch is still lacking in order to equal to other programming languages, as for functionality. With the new String manipulation blocks of Scratch 1.4, BYOB could even serve so many more possibilities! Like a "Play []" block that acts like an old Basic PLAY "" command... Wow .

I made a block that told you whether one number was divisible by another. This is an amazing way of doing things on scratch!

Hi The-Whiz. It's great that you're experimenting with BYOB and having fun with it. I just tried the sample projects and they work fine for me. Just remember that you need to open them - manually - in BYOB, not in Scratch (double clicking these samples will probably start Scratch instead of BYOB). You can open a sample in BYOB either through the open-dialog or by dragging a project in to the BYOB window.
