in reply to Spiraling integers

Btw, I have already written something similar in perl.

I had to generate the sequence of (x,y) coordinates in spiral, something like this:

0,0 0,1 1,1 1,0 1,-1 0,-1 -1,-1 -1,0 -1,1 -1,2 0,2 1,2 2,2 2,1 2,0 2,-1 ...

This was for an internet game. I wanted to discover the islands on a map with a ship in some order. This order is good becuse this way the ship travels only 1 units of distance in each step, so the discovery was fast, and I discovered the islands near my island first (as that's where the center of the spiral was).

Bots have since been banned in that game, so I have deleted the code. Sorry.
