An experiment using a hexagonal map in Unity.
The idea is to build it up into a simple turn-based wargame, on a hexagonal grid.
A lot of material was adapted from the tutorial on catlikecoding.com https://catlikecoding.com/unity/tutorials/hex-map/part-1/
An excellent (perhaps the authoritative) reference on hexagonal grids on Red Blob Games https://www.redblobgames.com/grids/hexagons/
