Lost City - May 18, 2004

Important

We are changing to LostCityRS/Server for future updates. This repo will remain up as an archive to look back on. We have moved away from a monorepo for the engine and content here.

Getting Started

Important

If you run into issues, please see our common issues.

1. Download and extract this repo somewhere on your computer.
2. Install our dependencies.
3. Open the folder you downloaded: Run the quickstart script and follow the on-screen prompts. You may disregard any severity warnings you see.

Once your setup process has completed, wait for it to tell you the world has started before trying to play.

The server includes its own web client, so you don't have to download a client!

Dependencies

• NodeJS 22
• Java 17 - later LTS versions are also fine.

Tip

If you're using VS Code (recommended), we have an extension to install on the marketplace.

Workflow

Content developers should run bun start. The server will watch for changes to scripts and configs, then automatically repack everything.

Engine developers should run bun run dev. This does what bun start does above, but also completely restarts the server when engine code has changed.

Common Issues

• bad option: --import

You are using an older version of Node. Reinstall and re-run.

• '"java"' is not recognized as an internal or external command

You do not have Java installed.

• XXXXX has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0

You are using Java 8 or Java 11. If you have multiple Java versions, you will need to set JAVA_PATH=path-to-java.exe in your .env file.
