More of a math question...
 

Okay, say I have a number of directions, in this example, 16.
I have a set dir1, 6.
And I also have dir2, 1.

How would I get the 'distance', or in this case, the number of directions dir1 is from dir2?
I know in the example I posted with it, it's 2 directions away, but what would be the formula to do this? The problem arises since, like in the example, dir1 is 15, and dir2 is 1, so abs(dir2-dir1)=14.
If any of this makes sense, any advice?

I would suggest just doing something like:

dist = abs(dir2 - dir1);
if (dist > 8) dist = 16 - dist;

Thanks, that worked great. :)
Though I ended up doing:
dist=abs(dir2-dir1)>8?16-abs(dir2-dir1):abs(dir2-dir1);

Hehe.
I just have an OCD think about repeating the same math formula over and over again :P

Oh I know, I thought the same thing at first... but meh, dunno, keeps it to one line so I like it.

Then do something like....
