A custom block is basically like any stack of blocks, you're right. But it can take arguments, and that several instances of the block can run at the same time in different stacks.

... and it can be recursive! (It can include a call to the same block.)

I don't quite understand how to make the blocks do anything. I'm trying to make one that changes the Blur radius of the sprite, but I can't seem to make it do anything.

Your question is so broad that I'm not positive that I understand what you're meaning to ask. You get a custom block to do something the same way you get any block to do something: put it in a script and run that script! Maybe you should post a picture of your definition and how you're trying to invoke it.

Questtion: How did you add the Elements part in?

Jens · 2010-05-06 12:58:05

I developed Elements in a modified Scratch image and exported the changeset. The changeset can be filed into other images (like the Scratch / BYOB) image. Afterwards some tweaking needs to be done, but essentially this works fine. Changesets is how you usually share code in Smalltalk and port it to other applications. If you're interested in the changeset (i.e. for Panther) I bet I can make it accessible somewhere.

Sounds like a bug in a recent version of BYOB. You should be able to load any existing Scratch project to BYOB. Can you post the the non-working project to website and point me to it, then I'll investigate and fix. Thanks!

and this is BYOB 2.99

[edit] downloaded 2.99.003. it works...but it's REALLY LAGGY

How do you post BYOB online?

Program card games using a list of the 52 cards in a deck...

Make a database of your favorite music/books/movies/foods...

Is this letter a vowel: [ [LIST <a> <e> <i> <o> <u>] CONTAINS <variable-with-letter>?]

Watch the tutorial on Lists and Higher Order Functions at http://byob.berkeley.edu

You can't post BYOB projects to the Scratch web site. You can upload projects to any site you can post to, and other people can download them, but you can't run them from the web site the way you can at scratch.mit.edu for Scratch projects. Sorry!

P.S. Maybe eventually there will be a BYOB web player, but not yet!

I did not. That was a normal scratch project that I was trying to run in BYOB

Hey Jens, when do you think BYOB 3 and Scratch4CS are coming out?

Hey, the same thing happened to me! The VM crashed and it gave me a .dmp(dump) file that I've been trying to open!

I'm not Jens but I'll answer anyway. Our target date for the "official" release of BYOB3 is the Scratch conference in August. I'd like to have something we feel good about calling a beta release by early July. But if you keep up with the alpha releases I don't expect you'll be hugely surprised by the finished product; the idea is to get the big new features in alpha, and then try to make the beta release(s) rock solid, well documented, and so on. (On my task list, for example, is help screens for the new BYOB blocks.)

"Scratch4cs" was the name of a proposal floated by the Scratch Team (look in the research area of their site) to fork off a separate version of Scratch for university CS students. That movie was called "Scratch4cs=Scratch" because it was my effort to persuade them that such a split would be undesirable, and unnecessary if they met the needs of CS students with a small number of powerful new blocks rather than with a large number of more specific blocks. So Jens and I aren't releasing a product called Scratch4cs. smile

Could you please go to Help>About BYOB and find the version number? If it's less than 2.99.007, please download a new BYOB.image from http://byob.berkeley.edu. (There are versions past 007, but those changes shouldn't be relevant to your problem.)

So I could post them to, say, a personal site, but not to the Scratch site? How would I do that?

You just upload your BYOB project file to the site, and people download it, and they have to have BYOB to run it. We don't have a web player. In other words, it's just like any other file you want to share.

piecar · 2010-05-15 14:12:25

Oh No!! I Did Not Mean To Download This!!!

So, it's the same as uploading, say, a PDF file, just that you need BYOB to run it.

This program is weird, I dont feel like downloading it now, im still using scratch.

A mac version? Of BYOB? There already is a mac version. I have it. You could just download the image file and open it with scratch. You don't have to download the whole application.
