Zen.Hexagons

Hexagon routines for use in for software that uses hexagon grids. Can be used for pointy-topped or flat-topped hexes and offset, axial or cube coordinate systems.

Uses ideas from Amit Patel's brilliant http://www.redblobgames.com/grids/hexagons/.

Nuget package download: https://www.nuget.org/packages/Zen.Hexagons/1.0.7

Example

To use:

var hexLibrary = new Zen.Hexagons.HexLibrary(HexType.FlatTopped, OffsetCoordinatesType.Odd, 64.0f);

var hexCube = hexLibrary.OffsetCoordinatesToCube(new HexOffsetCoordinates(2, 2));
var hexAxial = hexLibrary.OffsetCoordinatesToAxial(new HexOffsetCoordinates(2, 2));

var neighbors = hexLibrary.GetAllNeighbors(new HexOffsetCoordinates(1, 1));
var neighborNW = hexLibrary.GetNeighbor(new HexOffsetCoordinates(1, 1), Direction.NorthWest);

var ring1 = hexLibrary.GetSingleRing(new HexOffsetCoordinates(1, 1), 1);
var ring2 = hexLibrary.GetSingleRing(new HexOffsetCoordinates(2, 2), 2);

var ring3 = hexLibrary.GetSpiralRing(new HexOffsetCoordinates(2, 2), 2);

var line = hexLibrary.GetLine(new HexOffsetCoordinates(1, 0), new HexOffsetCoordinates(3, 4));

var distance = hexLibrary.GetDistance(new HexOffsetCoordinates(1, 0), new HexOffsetCoordinates(3, 4));

var pixel = hexLibrary.FromOffsetCoordinatesToPixel(new HexOffsetCoordinates(1, 1));

var coords = hexLibrary.FromPixelToOffsetCoordinates(96, 166);
