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

## Usage

Add dependency to your project
```
mapgen = "0.1"
```

Using single map generator:

```rust
use rand::prelude::*;
use mapgen::dungeon::{
    MapGenerator,
    cellular_automata::CellularAutomataGen
};

let mut rng = StdRng::seed_from_u64(100);
let gen = CellularAutomataGen::new(80, 50);
let map = gen.generate_map(&mut rng)
```

Use MapBuilder for chaining map generator and modifiers

```rust
use mapgen::dungeon::{
    MapBuilder,
    map::{Map, Point, TileType},
    cellular_automata::CellularAutomataGen,
    starting_point::{AreaStartingPosition, XStart, YStart},
    cull_unreachable::CullUnreachable,
};

let map = MapBuilder::new(Box::new(CellularAutomataGen::new(80, 50)))
            .with(AreaStartingPosition::new(XStart::CENTER, YStart::CENTER))
            .with(CullUnreachable::new())
            .build_map();
```

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.
