I don't totally understand that but why have blocks for it if you can just do <0=0> and <0=1>?

It's true that you can get around the lack of <true> and <false> but languages ought to give you a direct way to generate the constants of the language.  It's kind of as if you had to say <char 65> every time you wanted a letter "A"!

Scratch's handling of Boolean values has always been a little kludgy.  In some contexts, it uses the text strings "true" and "false"; in other contexts it uses the numbers 1 and 0 instead.  The Boolean blocks kind of promote Booleans to being taken seriously as a data type.  We included <true> and <false> blocks in BYOB, too, even though we were bending over backward not to introduce a lot of extra blocks.

In a perfect world, when you evaluate something like <1=0> the reported value would be the <false> block, not "false" or 0.  Alas, too many Scratch projects depend on the old behavior for us to dare to fix it!

To the developers of panther: I can make the online player. I have some knowledge of java, and my dad programs it for a living. Want My help? 

No, we have MathWizz already, but thanks!

Unless you can have CYOB work...

CYOB is written in Smalltalk!

Yes, made a project that scans a video feed of you at 10% of the size and then will record where your skin colour is. I can use this to make a game where you touch yellow blobs.

Cool...

Cloning DOES work...

And couldn't you do this:

(Make a variable called pixels, and a color called skin)

set skin to color at pixel ?, ?
set pixels to 1
repeat (number of pixels to scan)
set pixels to mix (skin) (pixels) and 1 color at pixel ? ?
change pixels by 1

Thats what im doing, but its long. And with cloning. Sometimes they delete themselfs. Before the porject is stopped and without deleting.

When you stop or click green flag, clones are deleted...

Plus, it works fine for me.

If I'm understanding this program correctly (I'm not sure I totally understand MIX), this will give pixels near the end higher weight in the mixture than pixels near the beginning.  You really want MIX to be variadic and/or take a list of colors as input.

Thats true, never thought about that. I have made a scanner that does it, I sent it for upload ages ago

Well its not likely to go up for a while now. Sparks is the one who gets all the emails.

Shal I post it somewhere else and have you upload it?

I don't know how to.

IDEA: Object grouping. So you could say if touching group1

and group1 contains (
sprite 1
sprite 2
)
so it saves code.

So you agree? and who else does?
