The implementation guide has code in C++, Javascript, C#, Python, Java, Typescript, and more. The code samples on this page are written in pseudo-code they're meant to be easy to read and understand. I wrote this guide to the most elegant approaches that lead to the simplest code, starting from the guides by Charles Fu and Clark Verbrugge. I've been collecting hex grid resources for over 25 years. This guide will cover various ways to make hexagonal grids, the relationships between different approaches, and common formulas and algorithms.
