Godot's High-level Multiplayer API can operate over WebRTC, however, it requires a signaling server to establish the WebRTC connections between all peers.
Nakama is an Open Source, scalable game server that provides many features, including user accounts, authentication, matchmaking, chat, and much more.
This Godot add-on provides some utility code to allow easily setting up those connections using Nakama as the signaling server.

-
Copy the
addons/,webrtc/andwebrtc_debug/directories into your project. -
Add the
Nakama.gdsingleton (inaddons/com.heroiclabs.nakama/) as an autoload in Godot. -
Add the
OnlineMatch.gdsingleton (inaddons/nakama-webrtc) as an autoload as well.
This project is a full demo showing how to use this addon, and, in fact, makes a pretty good template project to start from.
Download the full source code and import into Godot 3.2.3 to run.
Run docker-compose up -d in the top-level directory of the code to start a
Nakama instance with the default settings.
In both local and online mode, gamepads are supported, using the XBox A button to attack. The keyboard controls are WASD for movement and SPACE for attack.
In local mode, you can control player 2 using the arrow keys and ENTER to attack.
