Generate procedural maps for games. [Try it in the browser](https://klangner.github.io/mapgen.rs/) using WebAssembly.


## Map filters

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

### 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
  * [ ] Voronoi hive
  * [ ] Wave Function Collapse


## Usage

Add dependency to your project
```
mapgen = "0.4"
```

Using single map generator:

```rust
use rand::prelude::*;
use mapgen::{Map, MapFilter};
use mapgen::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 mapgen::{
    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))
        .build();
```

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 Roguelike in Rust.
