hexgridr

Install with npm

npm install hexgridr --save

Use with node.js

var HexGrid = require('hexgridr');

var hexGrid = new HexGrid(orientation, offsetType);
var hexSet = hexGrid.createHexSet(hexCount, layout, originX, originY);

//Example:
var hexGrid = new HexGrid('pointy-top','odd');
var hexSet = hexGrid.createHexSet(19, 'hexagon', 0, 0);

Check out the Demo page.

Parameters:
orientation {string}: 'pointy-top' or 'flat-top' The two supported types of hexes.
offsetType {string}: 'odd' or 'even' Rows (or columns) that contain the offset.
hexCount {int}: 0 to N Number of hexes.
layout {string}: 'hexagon' HexSet is build according to this layout. (more coming soon - rectangle).
originX {int}: X Coordinate of origin-hex. Each HexSet is build around the position of an origin-hex.
originY {int}: Y Coordinate of origin-hex. Each HexSet is build around the position of an origin-hex.

//You can also generate pixel-positions for a HexSet:
var pixelSet = hexSet.buildPixelSet(hexWidth, hexHeight, offsetX, offsetY);

//Example:
var pixelSet = hexSet.buildPixelGrid(64, 64, 256, 256);

Parameters:
hexWidth {int} : 0 to N -- pixel-width of a Hex.
hexHeight {int}: 0 to N -- pixel-height of a Hex.
offsetX {int}: 0 to N -- X (or left) pixel-position of the origin-hex.
offsetY {int}: 0 to N -- Y (or top) pixel-position of the origin-hex.

Remarks:
The center of each hex is used as the pivot point for positioning (hexWidth/2, hexHeight/2).

Internally the library is using a coordinate system with three axes for most calculations (pair-wise perpendicular triple - x,y,z). But all relevant output also contains an x,y representation compatible with rectangular coordinate systems.

Hexgridr is currently under heavy development. More features and a complete documentation coming soon.
