I geuss your very good at maths then.

Math.

And yes, I am advanced 2(.5? I'm in honors) years in my math class.

Hmmm, Mathsand I don't get along. I'm taking physics and robotics courses, both of which need it, but I really do have to concentrate... too bad, I love the non-maths bit

blockSpecs for average of _ and _ and _:

Code:

('average of %n and %n and %n' #r #average:and:and: 1 3 5)

Code for average:and:and: (In scratchmorph, other ops)

Code:

average: t1 and: t2 and: t3
|t4|
t4 _ t1 + t2 + t3 / 3.
^t4

blockSpecs for average of _ and _:

Code:

('average of %n and %n' #r #average:and: 1 3)

Code for average:and: (In scratchmorph, other ops)

Code:

average: t1 and: t2
|t3|
t3 _ t1 + t2 / 2.
^t3

blockSpecs for distance between _ and _:

Code:

('distance between %n and %n' #r #difference:and: 1 10)

Code for difference:and: (In scratchmorph, other ops)

Code:

difference: t1 and: t2
|t3|
t1 < t2 ifTrue: [t3 _ t2 - t1].
t2 < t1 ifTrue: [t3 _ t1 - t2].
t2 = t1 ifTrue: [t3 _ 0].
^t3

Good blocks! Allthough i have an idea for it! How about:
"Claculate average of items in list: [lists]"
AND
"Claculate average of items: (%n) to (%n) in list: [lists]"

What do you think?

Oh - and instead of distance between _ and _ I think it should be difference

I'm on it.

Er. there's a difference?

Well, the calculations to me seemed like it was calculating the difference between to numbers.
Allthought with a bit of ajustment they could be used to calculate the difference between the x and y posistions of two sprites like this:

Difference between X pos and X pos of sprite: [Sprite]

EDIT:: You could do 15x15

I'm not totally sure if Panther needs a starting sprite but I'll post it anyways.

A simple recolor of the Scratch sprite but I think it looks pretty good. Also I'm not sure if the original is copyrighted.

Grr... I'm not very good at list programming.

Could you use the getLine:ofList: function at all to help?

Code for getLine:ofList:

getLine: t1 ofList: t2 
    | t3 |
    t3 _ self listNamed: t2 ifNone: [^ ''].
    ^ t3 lineAt: (self lineNum: t1 forList: t3)

All I need is a repeat command for Smalltalk.

Math, do you know of a smalltalk repeat command?

nXIII, please read this! why does the (contents of file [ ]) not read a webpage if the path to the page is given, and how easy would it be to change it so it do so? I was thinking that would let us (for example) release a project that reads text from the Panther site so that people can hear the latest news and updates through the Scratch project! it would notify changes as well as naming featured projects, people, news and suchlike. It would also let projects read weather, news and other info off pages for use in project manipulation!^_^

EDIT: There would be no risk of a virus download seeing as it is only reading text, and not connecting in any other way to the internet, and it would be extremely useful.

COOL! Then we could make SWC MORE powerful! (You'd better know what that is.  )

oh I know    I saw it a while back, and it would be perfect for that! I hope nXIII is up to the challange of getting that to work... might be too hard.

I found the coding, and don't understand it. Yay.

I just make a 'file %s exists?' block!
