Make a world that wraps around without breaking distances at the seam

In a world where walking far enough east brings you back from the west, a monster just across the seam can look a whole map away, so it never notices you. This entry gives the AI the right way to measure across the seam and to keep positions inside the map.

Why this works

On a world that wraps, the map has no edge, so the shortest way between two points may cross the seam. Measure the shortest way round everywhere positions are compared, or one part of the game will see a neighbour and another will see a far-off stranger.

When not to use it

Do not wrap a world that has a meaning for its edges, such as a map with a real coast, a start and an end, or a story that moves from one side to the other. Use walls or sea there, and keep wrapping for worlds with no special place.
