Connect your game

Same protocol for web, Unity, or any client. Create an app in the dashboard, copy the App Key, then hello.

1. Create an app

Open the dashboard → Create app → copy the App Key.

2. WebSocket URL

wss://play.leoserver.art

3. JavaScript

const ws = new WebSocket("wss://play.leoserver.art");
const APP_KEY = "leo_…";          // from dashboard
let playerKey = localStorage.getItem("leo_player_key") || "";

ws.onopen = () => {
  ws.send(JSON.stringify({
    type: "hello",
    name: "Player",
    appKey: APP_KEY,
    playerKey: playerKey || undefined,
  }));
};

ws.onmessage = (e) => {
  const msg = JSON.parse(e.data);
  if (msg.type === "hello_ok") {
    localStorage.setItem("leo_player_key", msg.playerKey);
    ws.send(JSON.stringify({ type: "quick", game: "bluffer" }));
  }
  console.log(msg);
};

4. Unity (C#)

Use a WebSocket library (e.g. NativeWebSocket). First message after open:

using NativeWebSocket;
using UnityEngine;

public class LeoClient : MonoBehaviour {
  WebSocket ws;
  const string AppKey = "leo_…"; // from dashboard

  async void Start() {
    ws = new WebSocket("wss://play.leoserver.art");
    ws.OnOpen += () => {
      string playerKey = PlayerPrefs.GetString("leo_player_key", "");
      var hello = $"{{\"type\":\"hello\",\"name\":\"{name}\",\"appKey\":\"{AppKey}\"" +
                  (string.IsNullOrEmpty(playerKey) ? "" : $",\"playerKey\":\"{playerKey}\"") + "}";
      ws.SendText(hello);
    };
    ws.OnMessage += (bytes) => {
      var json = System.Text.Encoding.UTF8.GetString(bytes);
      Debug.Log(json);
      // parse hello_ok → save playerKey with PlayerPrefs
    };
    await ws.Connect();
  }

  void Update() { ws?.DispatchMessageQueue(); }
}
