MAPS STORE CUBE COORDINATES. MAPS STORE CUBE COORDINATES. MAPS STORE CUBE COOR
This means, you are not to draw using the coordinates stored in your map.
You are to draw using the cube_to_pixel of those coordinates.
If you wish to draw a hexagon to the screen, you must first use cube_to_pixel
to retrieve the center of the hexagon on each set of cube coordinates stored
in your map.
Information about the maps' dimensions are stored in a metatable, so you can
retrieve details about arbitrary maps after they are created.
