Engine-agnostic core SDK for Colyseus — includes Schema serialization, matchmaking, room management, and state synchronization.

Works with Unity, Godot (C#), MonoGame, and any .NET project.

Installation

dotnet add package Colyseus

Threading

When the client is created on a thread with a SynchronizationContext (Unity, Godot C#), Colyseus posts WebSocket callbacks back to that context automatically.

For engines without one, either register an external dispatcher through ColyseusContext.RegisterWebSocketForDispatch, or call room.Connection.DispatchMessageQueue() from your update loop.

Quick Example

using Colyseus;
using Colyseus.Schema;

var client = new Client("ws://localhost:2567");

var room = await client.JoinOrCreate<MyRoomState>("my_room");
Console.WriteLine("Joined room: " + room.Id);

var callbacks = Callbacks.Get(room);

callbacks.Listen(state => state.currentTurn, (currentValue, previousValue) => {
    Console.WriteLine($"Turn changed: {previousValue} -> {currentValue}");
});

callbacks.OnAdd(state => state.players, (sessionId, player) => {
    Console.WriteLine($"Player joined: {sessionId}");
});

room.Send("move", new { x = 10f, y = 20f });

room.OnMessage<string>("chat", (message) => {
    Console.WriteLine("Chat: " + message);
});
