Hex Grid
A library to easily work with 2d hex grids of arbitrary shapes. This library currently only supports "Pointy Top" hexagons.
Usage
Add this to your Cargo.toml
:
[dependencies]
hex_grid = "*"
and this to your crate root:
extern crate hex_grid;
Quick Start
use hex_grid::*;
use std::collections::HashMap;
struct CustomData{
//..whatever data you want associated with each tile
}
//empty grid
let mut grid: HashMap<Coordinate, CustomData> = HashMap::new();
//fill the grid with tiles in a hexagon shape of size 3
let coords = CENTER + Offset::fill_hex(3);
for coord in coords {
let data:CustomData = //...
grid.insert(coord, data);
}
//get the tile that is to the right 2 tiles from the center tile
let tile:Option<CustomData> = grid.get(CENTER + RIGHT*2);
