Re: ITopic: Build Your Own Blocks (BYOB)
Hi piko_12,
you cannot share a BYOB project on the Scratch website, because BYOB is an unofficial prototype for procedures which are currently unsupported by Scratch. You can, however, convert your project into an .exe file and share it in that form with your friends.

You have to modify the Source Code, which you can find here: http://scratch.wik.is/Source_Code. You need Squeak Smalltalk to modify it: http://www.squeak.org/Download/. I think you can also use Elements by downloading the "For Scratch" version which includes the Scratch source code.

Here's his first and only tutorial.

Not a question >:C

A Reporter is like a variable: It gives the script a number. Let's say you want to make a block named "pi". Create a reporter block. In the "report (--)" field you type what it reports to the script. Since the number Pi is equal to 3.14159265 (rounded up to 8 decimals, good for a Scratch script) write that. Then press OK, and you'll be able to use Pi in the script. You can also put anything else, such as other round (reporter) blocks.
A boolean is a true/false state. You could make a "Key Space RELEASED?" block by making a boolean which reports:
[blocks]<< <not> <key[ space ]pressed?> >>[/blocks].
Hope this helped.

Hi piko_12, in BYOB there's an internal compiler in the Extras-menu.
I can't get that function to work, for some reason.

Hmmm... I'll try it. I never noticed it
Uh, I can't find it. I'm using version 1.0.2, probably it was updated.

I like this program. But the problem is it runs a little slowly on my virtual pc (unsurprisingly) so I was wondering if there is the possibility of a mac version?
Heliosa, I believe you can just drop the .image file into a Scratch shortcut/The actual program.

Found out what's the problem. You're using BYOB 1.0.2 or earlier. BYOB 1.0.3 (I just updated to it) has a "Compile" button near "Save As", where "Share" should go.

Re: ITopic: Build Your Own Blocks (BYOB)
Hi Heliosa,
There seem to be two issues you're running into using BYOB. One is how to run it on Mac, the other is about the internal pseudo-compiler. As Magnie pointed out, you can just use the BYOB image together with your current Scratch environment. However, if you do that within the same folder that you're running regular Scratch from, Scratch will ask you to specify a Squeak image at every launch. So, the solution for this problem would be to create a separate folder for BYOB with a copy of all the Scratch files in it, and then to replace the file named Scratch.image with the one named BYOB.image.
The internal fake-compiler is still somewhat experimental and does not work correctly on every setup. There are especiall some constellations in combination with accented characters in pathnames which lead to problems. I'm also not sure if it (or the files it creates) works at all in a Windows emulator on a Mac.

Re: ITopic: Build Your Own Blocks (BYOB)
Chirp 1.2 is Scratch 1.2 but allows you to have the projects as Screen Savers. So I don't think so.

Re: ITopic: Build Your Own Blocks (BYOB)
i noticed that when you make a normal variable in BYOB, you can HIDE AND SHOW THEM!!! i hope this is in the next version of scratch!! and BYOB is awesome!
EDIT:
if BYOB was added to a new version of scratch, well, i'd be very happy!

You can already hide and show variables in Scratch. Are you sure you're using 1.3 or 1.3.1?

Re: ITopic: Build Your Own Blocks (BYOB)
Sometimes I also use a lot of variables, which have to be shown in the project. Does anybody have an idea how to set all variables to zero at the beginning? I want to create a block with BYOB, but I don't know how.

The only way I know is to set up a Green Flag script and set each variable to zero explicitly.
[blocks]
<when green flag clicked>
<set{ X1 }to( 0
<set{ X2 }to( 0
...and so on
[/blocks]
It's also a very good idea to put a short wait at the start of your other scripts that might be depending on the values being zero to give the project time to set them to zero.
