Bevy 3D Hex Example

I put together a small 3D hex grid for a game I was working on, and there was some interest in how I achieved that. I extracted that code into this repository for people to learn from.

It was heavily inspired by two main resources:

• Redblobgames' excellent writeup on hex grids
• Catlike Coding's tutorial series on hex grids in unity

Outline

I recommend perusing the source in this order:

• hex.rs: Simple hex-coordinate operations, such as neighbors and the like
• geometry.rs: Generates 3D points for a simple hex mesh
• main.rs: Wires this together to set up a bevy scene

Future

I don't have a lot of free time, so I didn't wrap this up in a bevy plugin for use by the community. If there's substantial interest, however, I might be talked into that.
