Graph Dungeon Generator

---

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 simple graph-based procedural dungeon generator.

Want to play with the generator? Try the demo here and have some fun 🧙‍♂️.

Running the project 🚀

1. Clone the repository.
2. Run yarn to install dependencies.
3. Run yarn dev to build and run the project and listen for changes.
4. Finally, double-click the public/index.html file to open the generator in your browser.

Examples

Given the same input graph, we can generate many dungeon shapes and pattern.

Architecture

The project is split into 3 distinct modules (aka folders) in an effort to separate concerns:

• /generate: where all the generation code lies (returns an Node<Room> tree).
• /draw: where we take the Node<Room> tree, generate a tilesmap, and render it to an HTML canvas with some debugging information.
• /graphs: the list of input files used to generate the dungeon. Currently written in TypeScript for type safety, but could as well be JSON files.

What can it do? 👍

• Generate a dungeon given a non-circular graph
• Backtracking when it cannot find a suitable spot for a child node
• Elegantly place the corridors between rooms
• Transform a node tree into a tilesmap
• Render contextual information for convenience
• Easily modifiable to add new room types and colors

What can't it do? 👎

This generator does not handle overly complex situations such as:

• Nodes with too many children
• L-shaped corridors
• Circular nodes (ex: A → B → C → A)

Roadmap 🗺️

• Prevent rooms from touching sides which doesn't respect graph constraints
• Pick from a set of predefined rooms that are rectangles
