Minimalist Scala and Python library to convert world coordinates to hex lattice coordinates based on http://www.redblobgames.com/grids/hexagons excellent reference implementation.

This library implements the following functions:

• Convert XY world coordinates into Hex RowCol.
• Convert Hex center into XY world coordinates.
• Get a sequence of the Hex corners in world coordinates.
• Get a sequence of Hexes that are within a user defined range from a given Hex.

Building the Project

mvn clean install

Install python modules:

python setup install

The build process is based on sbt.

sbt clean cleanFiles transitiveUpdate +publishM2 +publishLocal

Hex Viewer

HexApp is a simple CLI application to view the above functions in action.

View the app usage using:

sbt "run -help"

The following is a sample execution:

sbt "run -w 400 -h 400 -x 253 -y 177 -r 3 -o /tmp/test.png" && open /tmp/test.png
