Yeah, that's what happens when the .changes doesn't match the .image; download today's version 004 which provides both.

Does BYOB add to the ScratchSkin? If so, where can I download a BYOBSkin?

Well, we are already distributing what few pictures we've been adding to BYOB (pause resume icons, slot shapes, the Alonzo mascot, the logo) - they're all in the image, and can be modified at will

But Slash modufies the ScratchSkin and it needs to have a BYOB-ized skin to work.

Hi Billybob-Mario,

I'm getting a little weary of writing up Squeak How-To's, because it's all in there for you to discover for yourself. And it's fun, too, sort of like hunting down whodunnit in a mystery novel. Here's what Sherlock would do:

Browse the class side of ScratchFrame. There's a class variable named ScratchSkin inthere. Inspect it: It's a Dictionary (a kind of Collection). Inspect any key, and what you get is a ColoredForm, a kind of Form. Browse the Form class to find out that it's a
bitmap, and that there's a method category called "fileIn/Out". browse those methods, and check out #writeBMPFileNamed:  #writeGIFFileNamed: etc. try any of these in the Form inspector's evaluation panes and see what they do. Now check out how you can iterate over a Collection (#do: aBlock is a great start). Try this in the Dictionary's evaluation pane.

Case solved, now hand over the villain to Scottland Yard 
It's fun to find these things out for yourself!

Thank you. I don't think that there will be any more problems.

sweet!

BYOB works great    Too bad you can't share projects made with it with people without the program.

But you can!  In the SHARE menu, click "Compile this project."  It'll make a standalone executable that contains the project and BYOB, and when run it'll run the project in presentation mode.

hey i wanted to make a <key[backspace]pressed?> block but i dont know how can anyone tell me

Now there is. I found the dictionary and I have the, but now it seems a bit vague. How do I make the images into files?

See above.

I looked at them. Now what?

What did you learn by looking at them?

I tried running it on one of the parts of the ScratchSkin, and it said that it was out of the 30-bit something or something.

strange, isn't it. But it doesn't seem to happen if you just file out everything as GIF. here's what works for me: Inspect ScratchFrame class variable ScratchSkin, and evaluate the following code in the inspector's bottom pane:

Code:

self keysDo: [:key | 
    (self at: key) writeGIFFileNamed: key asString, '.gif']

afterwards (it takes some time to write all of these 273 files) check your BOYB installation folder.

Any luck?

I think the problem was that I used BMP instead of GIF. Also, thanks for this, because I would have had to do all 273 separately!

Also, what's BOYB? (Bob, Own Your Blocks?)
