Here Be Dragons

Generate procedural maps for games.

Acknowledgments

This crate is based on mapgen.rs. Thanks to Krzysztof Langner for doing the hard work of implementing the many map generation algorithms this crate includes.

Map filters

This library consists of different map filters which can be combined to create custom map generators.

Implemented filters

Area exit point
Area starting point
BSP Interior
BSP Rooms
Cellular automata
Cull unreachable areas
Diffusion-Limited Aggregation (DLA)
Drunkard's walk
Maze
Noise generator
Prefabs
Room corridors nearest
Simple rooms
Voronoi hive
Wave Function Collapse

Usage

Add the dependency to your project

here_be_dragons = "0.1"

Using single map generator:

use rand::prelude::*;
use here_be_dragons::{Map, MapFilter};
use here_be_dragons::filter::CellularAutomata;

let mut rng = StdRng::seed_from_u64(100);
let gen = CellularAutomata::new();
let map = gen.modify_map(&mut rng, &Map::new(80, 50));

Use MapBuilder for chaining map generator and modifiers

use here_be_dragons::{
    MapBuilder,
    filter::{
        NoiseGenerator, 
        CellularAutomata,
        AreaStartingPosition,
        XStart, 
        YStart,
    },
};

let map = MapBuilder::new(80, 50)
        .with(NoiseGenerator::uniform())
        .with(CellularAutomata::new())
        .with(AreaStartingPosition::new(XStart::CENTER, YStart::CENTER))
        .with(CullUnreachable::new())
        .with(DistantExit::new())
        .build();

For more information check the docs.

This library is based on the code from the Roguelike tutorial. I highly recommend it for learning how to write a Roguelike in Rust.
