very rough proof of concept of multiplayer in unity using WebRTC for (ostensibly) robust voice chat and a relatively convenient SCTP networking stack (DataChannel). Connections are currently full-mesh so it probably won't scale past like 10 people.
The signaling server itself is a stupid broadcast channel through websocat:
websocat -t ws-l:127.0.0.1:3012 broadcast:mirror
proxied through nginx for TLS (which you probably need).
I have rough plans to switch to the livekit SFU, which also has a useful "room" concept. Will take some doing however, as their official SDK only works with unity webGL, not native unity.
there's a compatible plain javascript client for the same networking in webversion,
which is mostly the MDN webrtc signaling tutorial, but using that broadcast signaling
instead of anything more intelligent.
Some things the unity package manager should download for you after cloning the project. I think you'll manually need to add the following:
- Steam Audio
- OVRLipSync
- Alicia.vrm
