:: Wraparound Maps

In our games we only use the PHost built-in version of PWrap.

Quote from  http://phost.org/dox/wrapmap.htm:

PHOST implements one model of a wraparound universe. In a wraparound universe, ships that fly off the "edge" of the map appear on the other side of the universe. Thus, the universe behaves more like a sphere (or a torus) than a plane. For example, in the original VGA Planets map, you can fly from (1010,2000) due west (heading of 270) and after 20 LY of travel you will appear on the other side, at (2990,2000), where you will continue on your journey flying due west.
