Mosaic
Collaborative multiplayer Game where players rearrange fragments to form images.
Made in 72 hours for the "STOP WAITING FOR GODOT" Game Jam. You can play the web version on itch.
Details
This uses WebRTC to create a peer to peer network. A small signalling server is needed so that the peers can discover each other and exchange SDP offers as well as ICE candidates. The Mosaic Server I wrote uses python, but the protocol is quite simple and it should be easy to recreate it or adjust it to your needs.
I made this game in a quite limited timeframe so please expect bugs. I also did not follow best practices wherever that would save some time in the sort term. For a long term project that is probably not the best approach.
Most code files have at least a small description on the top. If you have questions don't hesitate to ask, I did not add many comments to the code.
Running the Project
To run this project you will first need to start your own signalling server. You can download it from the Mosaic Server repo.
After that you will need to edit the src/network_mesh/NetworkMesh.gd file.
You should adjust the _websocket_url to point to your server (defaults to localhost)
and add some STUN/TURN servers to _ice_servers.
If you test this locally you can use an empty list of URLs. This will only work if clients can communicate with each other without the need to use STUN/TURN (for example multiple clients running on the same computer).
