WebRTC signalling server capable of setting up Peer-to-Peer network game connections for multiplayer.
Features a "connect and forget" approach to p2p multiplayer (users will automatically disconnect from the signalling server after their peer-to-peer game has been setup and started).
Signalling server features: hosting multiple different game profiles, private lobbies, public lobbies, and automatic queues for multiplayer.
Run server.js on hosted platform (e.g. heroku) and note the web address.
In Godot/Redot, copy the addons folder to project directory and enable the plugin.
Use the custom node PeerToPeerMultiplayer to setup your RTC connections. Url to
hosted socket server should begin with either prefix ws:// or wss:// depending on how
your hosted server is configured.
