Hi Billybob-Mario,

it's great that you're trying to incorporate BYOB in your Scratch mod! That's exactly why we made it easy to switch into development mode. Unfortunately, it's not just importing a file (like the .changes file) that will make it work. Also, the comments shouldn't be the problem. What you need is the changesets in their correct order. But these aren't really  well kept in BYOB, because mostly I've been hacking away under great time pressure, often switching back and forth between changesets, and sometimes not creating new ones when I should have. Also, BYOB fundamentally changes almost everything internal in Scratch, even the most simply code like moving a Sprite forward by 10 steps, because of the nested sprites feature. Therefore my advice would be to do it the other way round: Why not file out your changes file them into BYOB and make the adjustments you need. I'm pretty sure that this would be way easier and might just work.

Good luck!

The comments are a problem because they cause errors. It goes in alphabetical order, and right now I'm on F.

Update: only a couple of minutes later, I'm on H, but it's usually slower, and it took me a while to get to the point where I could get anywhere.

Now it all blew up.

After damage control, I'm back at C.

Now I'm back at F.

Now I'm on M.

I'm on R.

Also, it makes an error when I save: does not understand isHorizontal. It does save, though.

okay, maybe I did not make this really clear: You cannot import the .changes file. You can export / import classes, methods, categories and changesets. The .changes file is part of Squeak's code database, it only works with the particular image for which it is maintained and is not a stand-alone repository. The thing to do is to export your features as .cs files and integrate them one by one into the BYOB development image 

I tried to do that and got an error when editing the first existing method.

Hey guys, guess what, in my collapsable scripts suggestion thread, (I'm pretty sure) Lightnin just said that they are implementing something like BYOB in Scratch 2.0! 

"Something like" are the key words here.  At one point they were talking about procedures without inputs or reports -- basically, the functionality of BROADCAST AND WAIT with a different notation.  When I was there I made an impassioned plea for all of BYOB, but I don't know whether it will be successful.

EDIT: But even commands without inputs would indeed solve the clutter problem you're trying to solve with collapsable scripts, so it was right for Lightnin to say it in that context.

You can run it on a Mac! A much more recent, beta version, which is also compatible with Macs, can be found here.

Yeah I know, but unless things have changed in the three weeks or so since I visited the Scratch Team at the Media Lab, what they mean by adding procedures is still unclear.  I agree that the fact that Lightnin used the word "functions" is a good sign; that's more than they were committing to when we met!

But we'll win them over.

How can I do it?

Hi mherma,

I'm not really familiar with the WeDo set (last time I checked it was kinda hard to purchase one in Germany), but I suspect that you can only connect a single motor to each Scratch / BYOB session

   hey gang, can anybody confirm this? thanks!

I guess you could use a second computer and the mesh network, though. In this case each computer would be connected to a single motor, but both BYOB sessions would be joined in a (local) mesh network. Then you could set up your own broadcasts and events....

What do you think?

Hello. I was making a custom block in BYOB 2.99.007. When I clicked on it, it said, "Call me." I put it in a call block. It said, "Wow, you're a smart one. Now call ME!" I put it in another call block. It asked me to input please. It asked me to run it. It asked me to run it with my name. Then it said, It was nice talking to you. Congratulations for figuring out this little riddle. You are now a certified lambdaist. Does anyone know about this? Does lambdaist refer to lambda caluclus?

Hi EvilGenius,

congrats for figuring out or little "easter egg"! Unfortunately I had to take it out in the newer versions, because in certain constellation it was interfering with other code. But we'll come up with something else 

I did that too! Too bad you had to take it out in later versions.

Hi, I'm Jean M. and I'd like to learn more about BYOB. I've made several blocks already, but they are simple ones like a costume changer that lets you go to a previous costume and and some blocks that just combine two blocks. Can somebody tell me where I can get to the raw source code and actually  put in my own block codes?

There are ways to hack BYOB, but I think the best is to us the built in Elements editor. It's basically a visual Squeak browser, which lets you make or edit anything you want. To access it, right click on any block and and click 'edit elements' and you're in. Using it is just like using Scratch. Well, the graphics are a little different, and you need to know Squeak to use it, but It's easier than having to type everything.


PS: Jens/bharvey, Elements is broken in the newest BYOB image, you may want to fix that.

@ JeanTheFox: I'd recommend going through some of the tutorials and then trying some more complex blocks, especially ones using recursion or higher order functions (these are two of the major themes for BYOB). You should be able to create these in BYOB itself, without using Smalltalk.

@ ScratchReallyROCKS: Thanks for the bug report. I'll post the .changes file together with new versions, so you'll be able to Elements and Squeak again.

It always causes an error when I open an existing method.
