Maps should not have hard borders, bu rather be folded in toroid.

Calculating distance becomes a bit tricky since the units on opposite sides of the map should actually be close together.

Actually, this proves to be rather simple.
For a grid: sqrt(min(|x1 - x2|, w - |x1 - x2|)^2 + min(|y1 - y2|, h - |y1-y2|)^2)
