SetNet

A modular .NET networking library for games — server-authoritative communication over TCP, UDP or both, with a large catalog of opt-in companion packages (rooms, matchmaking, inventory, combat, mobs, pathfinding, StateSync, and more).

This site has three parts:

• Guide — how SetNet works: transports, handlers, the unified protocol, lifecycle, production hardening.
• Modules — every companion package, with its own README (what it does + usage).
• API Reference — the full, generated reference for every public type, property and method of every package — pulled straight from the source XML docs, so each variable and option is documented.

Quick start

// pick a serializer once
SetNetSerializer.Use(new MessagePackNetSerializer());

// a server
var server = new MyServer(new Configuration { Host = "0.0.0.0", Port = 5000, TransportType = TransportType.Both });
await server.StartAsync();

// a client
var client = new MyClient(new Configuration { Host = "127.0.0.1", Port = 5000 });
await client.ConnectAsync();
await client.SendAsync((ushort)Msg.Hello, new Hello { Text = "hi" });

Everything above the transport — handlers, RPC, rooms, StateSync, the whole game stack — is added by composition: XxxRuntime.Enable() + server.UseXxx() / client.UseXxx(). Pull only what you need.
