Blackholio
Blackholio is a small-scoped MMORPG built using Unity and SpacetimeDB, designed to showcase scalable multiplayer game development. Inspired by agar.io, Blackholio reimagines the mechanics with a space theme where players become planets, stars, and black holes in a competitive cosmic arena.
Game Overview
- Gameplay: Absorb smaller entities, grow, evolve, and dominate the leaderboard as a black hole.
- Scale: Supports hundreds of players seamlessly with SpacetimeDB's real-time synchronization.
- Objective: Demonstrate SpacetimeDB's features and best practices in a fun, interactive project.
Tutorial Overview
This repository accompanies the Blackholio Unity Tutorial, which guides you through building the game from scratch while learning:
- Unity integration with SpacetimeDB.
- Client-server setup for multiplayer games.
- SpacetimeDB features, including reducers, tables, and scheduled events.
By following the tutorial, you'll develop:
- A basic understanding of SpacetimeDB for multiplayer games.
- A functional game prototype with scalable multiplayer features.

Getting Started
If you want to follow a more structured tutorial where it shows you how to set everything up, start with our Blackholio Tutorial.
If you just want to checkout the final project and play around a bit, follow these steps:
- Install SpacetimeDB CLI
- Start SpacetimeDB in a separate terminal with
spacetime start. - Clone this repository:
git clone https://github.com/ClockworkLabs/SpacetimeDB.git cd SpacetimeDB/demo/Blackholio - Publish the server logic. You can either publish the csharp server or the rust server.
cd server-rust/ # Upload the module to SpacetimeDB bash ./publish.sh # Update the client bindings in case they are out of date bash ./generate.sh - Install Unity Hub and Unity version 2021.2 or newer.
- Open the scene named
Main.unity - Hit play!
You should be prompted for a username and you should be able to move around, eat food and defeat other players!
