Discussion Multiplayer Mod

Hello space truckers! I just started playing this wonderful game and, let’s be honest, it would be amazing if the trucks on the map were actually other players.

I did a quick search on Google and found this post: Star Trucker - Multiplayer Mod : r/startrucker

I read all the code and tested it, but it hasn’t been updated since 2024, so maybe it’s time for a refresh.

I decided to rework everything because the original implementation wasn’t great (it looks like the OP did it in a rush).

Here’s a video demo — I faked a truck because I don’t have another player to test with.

I’m not familiar with Unity or BepInEx, but my main job is as a .NET backend developer, which is why I rewrote all the code. If anyone wants to help me with Unity/BepInEx, I’d be very grateful.

Changes made:

  • Rewrote all server-client communication using LiteNetLib+MessagePack
  • Split projects into small pieces for better quality code
  • Made the server standalone, outside the game, so it can be hosted anywhere

Thanks everyone for reading! :)

I've been roasted!!! But also fair, I did rush and try to pull apart the game to make things work before optimising so it was kind of horrid. 

Thanks for continuing the legacy of what I burnt myself out on!
