Module map18xx::tile

Representation of tiles

Items within a hex are usually given in hexagon-space. This is a 3D space where the axis are at 60° to each other. An example of the axis is given below. Note that the orientation of the axis when the hexagons are oriented with horizontal edges differs from when the hexagons are oriented with vertical edges.

Instead of using coordinates in hexagon-space there are these position codes that can be used as a shortcut. North is the upper edge on a hexagon that has horizontal edges, it is the top left edge on hexagons that are oriented vertically.

• N: north edge
• NE: north east edge
• NW: north west edge
• S: south edge
• SE: south east edge
• SW: south west edge
• C: center of hexagon
