Constructors

A position on a hexagonal grid, in trapezoidal coordinates.

Constructors

Pos	The distance along the N/S axis is given by `x + y`.
Fields x :: !Int The distance along the NE/SW axis. y :: !Int The distance along the NW/SE axis.

A representation of all hexagons touched along a path.

Constructors

Chart
Fields bounds :: ((Int, Int), (Int, Int)) Cartesian bounding box. maxDistance :: Int The maximum distance from origin. path :: [((Int, Int), Int)] Hexagons and distances from origin.

Parse comma-separated steps.

Move from a position by one step.

Returns the minimum number of steps required to reach the origin.
