SimpleWebRTC is a Unity-based WebRTC wrapper that facilitates peer-to-peer audio, video, and data communication over WebRTC using Unitys WebRTC package https://docs.unity3d.com/Packages/com.unity.webrtc@3.0/manual/index.html. It leverages WebSockets for signaling and supports both video and audio streaming.

Usage of WebRTCConnection Component

The WebRTCConnection component manages the WebRTC connection and can be attached to a GameObject in Unity.

Following sample scenes are included in the pacakge:

• WebSocket-TestConnection: For testing the wecksocket connection separately.
• WebRTC-SingleClient-STUNConnection: Testing STUN connection for a single client. Works standalone and can be deployed to clients. Make sure to set the LocalPeerId for each client individually.
• WebRTC-SingleClient-wLobby-STUNConnection: A simple Lobby example for handling multiple STUN WebRTC clients. SimpleLobbyManager.cs shows an example, how to use SimpleWebRTC via C#.
• WebRTC-MultipleClients-STUNConnection: Shows how multiple clients can be connected via peer-to-peer connections and share data, video and audio transmissions.

Example code

WebRTCConnection connection = gameObject.GetComponent<WebRTCConnection>();

connection.Connect(); // Establish WebSocket connection

// after a WebRTC peer-to-peer connection is established

connection.StartVideoTransmission(); // Begin video streaming

connection.SendDataChannelMessage("Hello Peer!"); // Send a message over the data channel
