How does 'b' work?

[OrangeTux]

I'm not sure if b is broken or I use it wrong.

As I understand b 'bounces' back and forth over a sequence which boundaries are given by the parameters of b. So the following example should output 1, 2, 3, 4, 5, 6, 7, 6, 5, 4, 3, 2, 1 and so on:

1B7
.1.

Is my understanding of b correct? If so, than b seem to be broken. The output of b doesn't change. Using Orca 0.7.1 on Ubuntu

Hi,

if your B is in capital it should work as you said. Otherwise you need to bang your b operator.

You got it right, and it's not broken.
I think the best way to understand how B works is to try and visualize the result, try:

7B4.
.3.X

If you change the first port, you'll notice that the X output goes back and forth. Alternatively, you can automate it with something like:

#.incr.#....#.clock.#
.....................
I8..........I8.......
6B4.........4B4......
.2.X.........0.X.....

You can run this program to see the way B works in more details too.

..Cf..fCf
xVd..yV9.
.........
..3Kx.y..
2KxydB9..
..d9X4...

well i clone the latest version under windows 10 and it seems to be stuck for me too. So @OrangeTux you may be right...

by the way, I always fight to find the number version of Orca. Why not display it obviously ?
the shortcut is cmd + r right ? The About menu could be a lovely place no ?

[neauoire]

There is no menu for browser-version users and OSX users, but I could display the version number a few more frames.

[nlebellier]

Ok i miss the change of the b behaviour (the initials B.B.) but i must admit i don't catch how it works.

[neauoire]

It works just like before, but it takes a value as input, which can be a clock(C8 in B4) will work the same as before, or a I8 if you don't want to sync with the clock.

ok but now the B operator needs a friend to work, before it was independent. So B "bounce" alone is just a substraction operator right in absolute value ? So the "bounce" name is quiet weird no ?

[neauoire]

It does need a friend to work now yes, how would you call it now? I'm not against renaming it. If you have a better name that starts with B, I'll take it :)

[nlebellier]

Well B as Between : returns the absolute value of the subtraction between the two terms

[neauoire]

Perfect :) I like it!, would you like to add it yourself to library.js, and make a pull request?

[nlebellier]

Done !

thanks!
