Real-Time and Turn-Based Multiplayer Support

V-Play Multiplayer supports both real-time and turn-based gameplay, so you can use it to make many different types of multiplayer games. It's perfect for making player-vs-player games like 'Words with Friends' or games for a large amount of players, such as 'Clash of Clans'.

With V-Play Multiplayer, you can now rival these games and make whatever kind of multiplayer game you like.

Matchmaking and ELO Rating System

V-Play Multiplayer includes a matchmaking feature that allows you to play with your friends or join already running games. It also includes an ELO Rating System that matches players against opponents of a similar skill level to ensure competitive gameplay.

Friend System and Social Features

V-Play Multiplayer lets you add your friends or make new friends with players you meet in-game. You can also compare your highscore with your friend’s in a dedicated Friends leaderboard.

These leaderboards are sure to increase your retention and engagement rates as players compete against friends and international players to reach the top of the rankings.

Interactive Chat & Push Notification

V-Play Multiplayer features a messaging system so you can chat with your friends, even if they’re not online. This makes it easy to discuss games or arrange future matches. Best of all, V-Play Multiplayer sends Push Notifications to players when they receive new messages or game invites.

In-Game Chat

V-Play Multiplayer allows players to communicate during gameplay with an in-game chat feature. Players can use it to discuss game results with one another, message their friends or chat about the latest news with people from all over the world, right in a running game.

This feature adds a strong social element to any multiplayer game and creates an engaging experience for young and old players alike.

Example Implementation

This is an example of a minimum QML implementation of a turn-based multiplayer game. It features the default matchmaking UI and players take turns in clicking one button.

Matchmaking

The default matchmaking UI allows you to create games, join games and even invite other players and friends.

Turn-Based Gameplay

Only one player is active at a time. The server is notifiying each player when it's their turn.

Get your own gameId

You can run this example with the gameId we provided, or you can create your own gameId in the V-Play Game Network Web Dashboard.

 import VPlay 2.0
 import QtQuick 2.0

 GameWindow {
   id: gameWindow

   VPlayGameNetwork {
     id: gameNetwork
     gameId: 251 // create your own gameId in the Web Dashboard
     secret: "averygoodsecret"
     multiplayerItem: multiplayer
   }

   VPlayMultiplayer {
     id: multiplayer
     appKey: '24e9abae-1abc-41d6-8a46-ce4622c928e8'
     gameNetworkItem: gameNetwork
     multiplayerView: multiplayerView
     playerCount: 2
     onGameStarted: { // this signal is emited when the multiplayer game starts
       matchmakingScene.visible = false // hide the matchmaking scene
       gameScene.visible = true // and show the game scene instead
     }
   }

   Scene { // our matchmaking scene
     id: matchmakingScene

     VPlayMultiplayerView { // adds the default multiplayer UI
       id: multiplayerView
     }
   }

   Scene { // our game scene
     id: gameScene
     visible: false // hidden at startup, shown when the multiplayer game starts

     StyledButton {
       anchors.centerIn: parent
       // we use property bindings to check if it's our turn
       // we could also listen to the signals of the multiplayer item instead
       enabled: multiplayer.myTurn // enable this button only if it is my turn
       color: multiplayer.myTurn ? "lightgreen" : "grey"
       text: multiplayer.amLeader ? "PING" : "PONG" // host: "PING", player: "PONG"
       onClicked: {
         multiplayer.triggerNextTurn() // finished turn on button click
       }
     }
   }
 }
