# Here Be Dragons

[![Crates.io](https://img.shields.io/crates/v/here_be_dragons.svg)](https://crates.io/crates/here_be_dragons)
[![here_be_dragons](https://docs.rs/here_be_dragons/badge.svg)](https://docs.rs/here_be_dragons/)

Generate procedural maps for games.

## Acknowledgments

This crate is based on [mapgen.rs](https://github.com/klangner/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

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

## Usage

Add the dependency to your project
```
here_be_dragons = "0.1"
```

Using single map generator:

```rust
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

```rust
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](https://docs.rs/here_be_dragons).

This library is based on the code from the [Roguelike tutorial](https://github.com/thebracket/rustrogueliketutorial). I highly recommend it for learning how to write a Roguelike in Rust.
