A web app for playing Forged in the Dark games online. d6 Together uses ws for networking, Rapier 3D for physics, and three.js for 3D rendering.
You can build and run your own server from the source code; all you strictly need is NodeJS (v18.20 or later). You can get the source code from GitHub.
Once you have the code, execute the following commands within the project root to start the server.
# Get dependencies (only needed the first time)
npm install
# Build the application from source (only needed the first time and after changes to the source)
npm run build
# Run server
npm run serverBy default, d6 Together uses port 6462. This can be easily changed at the top of d6-together.js (changing the port does NOT require re-building the app). Use your browser to connect to the server (e.g. localhost:6462), and you're all set!
When deploying to a production environment, you'll need the dist/ directory (which is created with npm run build), d6-together.js, and the package.json and package-lock.json files. Running npm install --omit=dev will install the necessary dependencies, and npm run server will run the server. For convenience, those two commands are combined in npm run deploy.
If you want to host the files locally but connect to a remote d6 Together WebSocket server, you can easily change the target server using window.d6t.WS_ADDRESS. Either edit multiplayer.js to change the default assignment or open up your web browser's console on d6 Together and reassign window.d6t.WS_ADDRESS before hosting or joining. However, this will not work without some server-side configuration.
By default, d6 Together WS servers will reject connections where the host (the WS server) and origin (the HTTP server) do not match. This can be changed by editing d6-together.js, specifically the variable REJECT_HOST_ORIGIN_DIFF. Similarly, you can arbitrarily restrict origins by editing the allowOrigin(origin) function.
