Mixite is a hexagonal grid library. The motivation behind it is to have an optimized, simple and usable library for drawing hexagonal grids without being tied to any GUI framework.

This means that you can use Mixite on Android, your backend or your desktop app.

There is a REST-based web example which you can tinker with here. (not recommended, this is under rewrite)

You can also check out the mixite.example.swt project here.

Mixite currently supports a maximum grid size of 1000 * 1000 (1.000.000 cells) with the default implementation but you can provide your own storage implementation to alleviate this limitation.

Disclaimer for Java users: There is no need to worry, Mixite works in exactly the same way as Hexameter worked before. Java interop is seamless, you only have to change the imports / project dependency.

As always with Maven Central artifacts: previous versions of Hexameter also work, they are not affected.

Getting started

This library uses Amit's guide to hexagonal grids. The coordinate system used by this library is the Cubic coordinate system. Please check here for further details.

Hexagonal grids come in flat topped and pointy topped shapes. The grid can have several layouts:

  • Hexagonal: the width and height of a this layout has to be equal and both have to be an odd number.
  • Triangular: the width and height of a this layout has to be equal.
  • Rectangular: no special rules
  • Trapezoid: no special rules
  • Custom: your own implementation of GridLayoutStrategy

All layouts have width and height values of at least 1. You can consult HexagonalGridLayout if you need further details.

This library is not tied to any GUI implementation. All operations provided by the API work using the most abstract concept possible.

Basic usage

Importing Mixite

Let's start by adding Mixite as a dependency.


    <url></url> <!-- Mixite uses Jitpack repository -->


allprojects {
  repositories {
    maven { url '' } // Mixite uses Jitpack repository
dependencies {
  implementation 'com.github.Hexworks.mixite:mixite.core-jvm:2018.2.0-RELEASE'

Note that if you are using Javascript you need mixite.core-web: 'org.hexworks.mixite:mixite.core-web:2018.2.0-RELEASE'

You can also use the latest preview versions, more info here.

Creating a grid

You can use the HexagonalGridBuilder to create a HexagonalGrid:

HexagonalGridBuilder<DefaultSatelliteData> builder = new HexagonalGridBuilder<>()
HexagonalGrid<DefaultSatelliteData> grid =;

You can also use it to create a HexagonalGridCalculator for you which supports advanced operations on HexagonalGrids:

HexagonalGridCalculator<DefaultSatelliteData> calc = builder.buildCalculatorFor(grid);
calc.calculateDistanceBetween(sourceHex, targetHex)

Drawing a grid

Method Grid.getHexagons returns an iterable collection of hexagons. Each Point represents a coordinate in 2D space that can be transformed for rendering.

for (Hexagon<DefaultSatelliteData> hexagon : grid.getHexagons()) {
  for(Point p : hexagon.getPoints()) {
    // Do you stuff with point.coordinateX, point.coordinateY

Manipulating your grid

There are basically only one operation for manipulating your data on the grid: The Hexagon#setSatelliteData(T data) operation with which you can add your own arbitrary data to a Hexagon object. This means that once created a HexagonalGrid is immutable apart from the satellite data you add.

There is also a HexagonalGrid#clearSatelliteData() method for clearing all satellite data from your grid.

The implementation of the HexagonalGrid is lazy. This means that it only stores data which is absolutely necessary to keep in memory (the coordinates and your satellite data). Everything else is generated on the fly. The only limiting factor of a grid at the moment is the coordinates (which consume memory) and the satellite data.

GUI example:

You can find a simple GUI example in the mixite.example.swt project. Run it by doing the following steps.

  1. Clone the project: git clone
  2. cd to the newly created mixite folder: cd mixite/
  3. build the project: ./gradlew clean build (or gradlew clean build on Windows)
  4. run the created uberjar: java -jar mixite.example.swt/build/libs/mixite.example.swt.jar

Supported operations

  • Querying the characteristics of the HexagonGrid
  • Fetching all the Hexagon objects from the grid
  • Getting a subset of Hexagons (using cube or offset coordinate range) from the grid
  • Checking whether a Hexagon is on a grid or not
  • Getting a Hexagon by its grid coordinate (cube)
  • Getting a Hexagon by its pixel coordinate
  • Getting the neighbors of a hexagon (also by index)

Advanced operations

  • Calculating the distance between two Hexagons
  • Calculating the movement range from a Hexagon to an other
  • Rotating a Hexagon
  • Calculating a ring from a Hexagon
  • Draw a line from a Hexagon to an other
  • Checking visibility of a Hexagon from an other
  • Adding custom data to a Hexagon
  • Clearing all custom data from the HexagonalGrid

Usage tips

  • You can add satellite data (any arbitrary data you have) to a Hexagon. By implementing the SatelliteData interface you gain operations like visibility checking
  • Mixite comes with a sensible default implementation of SatelliteData so if you don't want to add extra data you can use DefaultSatelliteData.
  • You can use your own implementation of HexagonDataStorage for storing your Hexagons
  • Mixite comes with a sensible DefaultHexagonDataStorage implementation which stores all data in memory
  • You don't have to fetch all Hexagon objects by using the getHexagons method. You can query Hexagons by a range using offset or cube coordinates

Road map

  • Path finding with obstacles (blocking movement)
  • Movement range with obstacles and movement cost calculation
  • Android example
