Recently I wanted to make a simple multiplayer game in Unity, but I didn’t want to use their terribly made UNET, as even though it’s barely a few years old, it’s already deprecated. I also didn’t want to go with a third party like Photon Networking, because I don’t want to pay for CCU (Concurrent User) usage, server costs, and other misc fees.
No, what I wanted was a solution such as Minecraft implements, where you directly connect to a server and it’s served through peer-to-peer networking, with one player being a server. The solution? A small library called LiteNetLib. This library allows you to build multiplayer games in .NET (C#), including Unity, with no limitations on usage, including player count. It was exactly what I needed.
The documentation is slightly sparse but it wasn’t rocket science to get a small example up and running, and the developer seems pretty open to questions. There’s also a small sample included so you can see what it entails.
