Sample unity3d project to demonstrate WebRTC official unity plugin. with simple WebRTC signaling implemented with Socket.IO.

• Unity3D 2017.3+
• node.js

• WebRTC (official) unity plugin: https://github.com/mhama/webrtc-dev-env

• Socket.IO library: https://github.com/floatinghotpot/socket.io-unity

• On Windows:

> server.bat

or

• On Mac/Linux

npm install
node index.js

• Output Log

>call npm install
npm WARN [email protected] No description
npm WARN [email protected] No repository field.

listening on *:3000

ngrok server: https://440ab904.ngrok.io

• The last "ngrok server" part is IMPORTANT!
• the server URL lasts for 24 hours only. After that, you need to restart server for another 24 hours.

build and run unity project.

• set the above ngrok server URL to app's server URL field. (but use http:// rather than https://)
• push Connect button
• push Offer with Camera button

• browse the above ngrok server URL with web browser. (the web browser needs to support WebRTC).
• push Start Camera button
• push Start Peer button

This sample use signaling with http long polling of Socket.IO. Very dirty implementation that doesnot handle bad states or errors.

Beware that WebRTC may use very much bandwidth! Beware especially if you are not using fixed price connection.
