Path Reversing Script

[Waveofbabies]

Hey y'all, I've found myself needing the ability to reverse a path, so I wrote a little script that I'd like to share!

Thanks! Wasn't too sure what the best way to avoid the if was.

I found reversing directions handy in several circumstances. Now I wonder, on a larger scale, if an object lookup or a calculation is more CPU efficient...

function reverse(dir){return (dir + 3)%8+1;}
reverse(LEFT);

vs
reverse:{TOP:BOTTOM,TOP_RIGHT:BOTTOM_LEFT,RIGHT:LEFT,BOTTOM_RIGHT:TOP_LEFT,BOTTOM:TOP,BOTTOM_LEFT:TOP_RIGHT,LEFT:RIGHT,TOP_LEFT:BOTTOM_RIGHT};
reverse[LEFT];

Good! Simple and useful!
