bevy_hex_coords

A library that provides hexagonal coordinate utilities, with accurate vertex and edge placement and rotation, for the Bevy game engine.

Warning

Not for production use. This library was built as a learning experience in deriving hexagonal grid semantics from first principles. No thought has been put into ergonomics and there is no guarantee that I will maintain this in the future.

Installation

cargo add bevy_hex_coords

Usage

use bevy::prelude::*;
use bevy_hex_coords::*;

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugins(HexCoordsPlugin {
            auto_attach_transforms: true,
        })
        .add_systems(Startup, setup)
        .run();
}

fn setup(mut commands: Commands) {
    commands.spawn((
        HexCoord::new(0, 0),
        HexUnitSize(32.0),
        Sprite::default(),
    ));
}
