Hello fellow game developer 🧙‍♂️!

I need less than 5 minutes of your precious time, feedback, and experience, to answer a few questions about multiplayer game development that will help me shape future projects. Survey is available at https://tally.so/r/w81Xr5 and requires no signup and no bs.

A configurable and editable dungeon generator using Binary-Space Partitioning and hand-made rooms running in the browser.

🕹️ Testing

A demo is available here https://halftheopposite.github.io/bsp-dungeon-generator.

💻 Running

If you want to run the development mode to generate dungeons or edit rooms you can run the yarn start command.

This will launch the development server where you will be able to:

• Edit rooms at http://localhost:3000/#/edit/
• Generate dungeons at http://localhost:3000/#/generate/

📕 Features

Editor

Using the edit mode you can: create, edit, or remove the rooms that are used for generating dungeons. The current editing session is saved to the local storage which makes it possible to continue editing later on.

• You can load a rooms.json file to start with.
• You can save a rooms.json to use in your own project.

Generator

In the generate mode, you can render dungeons by tuning some key parameters.

• You can download a JSON representation of the dungeon.
• You can right click and save the generated image.

⚙️ Package (NPM)

The project also comes with a published package on NPM @halftheopposite/dungeon, which bundles the generator's code only. The interactive editor and generator are excluded for package's weight reasons.

How to use the generator's code in your own project:

import { generate } from '@halftheopposite/dungeon';

const dungeon = generate({
  rooms: [...], // A list of templates (e.g. you can download the `rooms.json` from the online editor)
  mapWidth: 96,
  mapHeight: 56,
  mapGutterWidth: 1,
  iterations: 5,
  containerSplitRetries: 20,
  containerMinimumRatio: 0.45,
  containerMinimumSize: 4,
  corridorWidth: 2,
  seed: "dungeon",
});

This will return:

const result = {
    width: number;
    height: number;
    tree: TreeNode<Container>;
    layers: {
        tiles: TileMap;
        props: TileMap;
        monsters: TileMap;
    };
}
