While I'm at school and can't check the directional values (I think up is 0, right is 2, left is 1 and down is 3), I can explain the mod function Raspberry!

.

Mod never returns 0 or 1 (In the sense of true and false. It can if those numbers are the remainders). You can think of it as a number being subtracted by another number until it can't be subtracted any longer, and the remainder is given. For example:

10, mod, 3

10 is greater than 3, so subtract 3.
7 is greater than 3, so subtract 3.
4 is greater than 3, so subtract 3.
1 isn't greater than 3, so return 1.

Another example:

15, mod, 4

15 is greater than 4, so subtract 4.
11 is greater than 4, so subtract 4.
7 is greater than 4, so subtract 4.
3 isn't greater than 4, so return 3.

Now, it's not like the mod function itself is running a loop that is continuously subtracting the 2nd number from the 1st. That's just the best way I could explain it Raspberry!

. If you want to know an equation for it, I guess I could post that too but for now I won't bother since it isn't really that important.

So anyhow, there you go. Using mod was a much better thing to use than divide, but I can't tell how well it really works, heheh.

If you want to do some mod calculations real quick, I have a simple console app that I made:

the Mad Cacti's script was working, but i want him to face left from the current direction that he is facing , at the moment he just faces west and the same for right he just east

Cube: directions are 0=up, 1=left, 2=down, 3=right. So you can see that (x + 2), mod, 4 returns the opposite direction to any direction.

Flamer: An easier way to invision modulus is as the remainder to a division. 13 / 3 is 4 with a remainder of 1, and

4 * 3 + 1 = 13

As a random side note:
REMEMBER, the 'logic' functions (and, or, xor, etc) supplied with HamsterSpeak are not technically logical funuctions, but bitwise functions. And modulus has a different meaning is mathematics and programming.

Ok, xearo, I didn't think of that. Heres a finished script:

Thanks for all the help its finnaly running now, and hopefully i know more about scripts and should be able to figure it out next time

Few people would know how to/when to/would use the bitwise and math functions for this sort of thing. However, using them can sometimes be a great shortcut.
