Dual-channel live multiplayer gameplay — reliable WebSocket (TCP) plus an optional UDP fast lane for movement
public Realtime(string realtimeWebSocketUrl = "wss://realtime.michitai.com")Initializes realtime WebSocket client with optional custom server URL. Default: wss://realtime.michitai.com
public static async Task<TokenResponse> GetTokenAsync(
Client client,
string playerToken
)Static method to generate realtime authentication token using API client.
public async Task<bool> ConnectAsync(string realtimeToken)Connects to WebSocket server using realtime token. Returns true if successful, false if failed. Includes connection state protection.
public async Task SendAsync<T>(
ERoomTargetPlayer target,
string command,
T data = null,
int[] targetIds = null
)Sends a message to specific targets (Host, All, Others, or specific player IDs) with optional data. Uses JsonUtility for serialization.
public async Task<bool> ConnectUdpAsync(int? udpPort = null)Binds one UDP endpoint alongside the WebSocket (max 1 TCP + 1 UDP per player). Call after ConnectAsync — datagrams authenticate with the server-issued connection id. Not supported on WebGL; returns false there.
public async Task SendUnreliableAsync<T>(
ERoomTargetPlayer target,
string command,
T data = null,
int[] targetIds = null
)Sends over the bound UDP channel — unordered, unacknowledged, latest-wins via seq. Ideal for 20-60Hz movement/state streams. Falls back to the WebSocket when UDP isn't bound.
public sealed class PredictionBuffer<TState, TInput> {
uint NextSeq(); void Record(uint seq, TInput input, TState state);
TState Reconcile(uint ackSeq, TState authoritative,
Func<TState,TInput,float,TState> apply, float dt);
}
public sealed class SnapshotBuffer<TState> {
void Add(double t, TState s, uint seq = 0);
bool TrySample(double renderTime,
Func<TState,TState,double,TState> lerp, out TState result);
}Client-side movement prediction: record each input with its seq, adopt authoritative state on arrival, replay unacked inputs. SnapshotBuffer interpolates remote entities ~100ms in the past. Both in Multiplayer/Rooms/Realtime/Prediction.cs.
public string ConnectionId { get; }
public bool IsUdpConnected { get; }
public int LastUdpRttMs { get; }ConnectionId: the session id (also authenticates UDP datagrams). IsUdpConnected: UDP binding state. LastUdpRttMs: measured datagram round-trip time.
public async Task DisconnectAsync()Disconnects from the server and cleans up both channels. Automatically called in OnDestroy.
public event Action<string, string, SenderInfo> OnReceive;
public event Action OnConnected;OnConnected: Fired when WebSocket connection is established. OnReceive: Fired when a message is received from server with command, data, and sender information.
