text: In the last lesson you've learned how to add achievements and leaderboards to your game to increase player retention. Today we'll have a look at how you can increase your game downloads and increase player retention even more!
  One of the biggest benefits of Felgo Game Network is the built-in Facebook connection. Although your players can also achieve highscores and achievements without connecting to their Facebook account, they get the following benefits after connecting with Facebook:
  In your game, it is advisable to communicate these benefits to your players. You can do so by checking the facebookConnectionSuccessful property at app startup, and ask the player to connect to gain these benefits. In the ProfileView, a part of the default GameNetworkView, we also have communicated the benefits as you can see in the following picture. Based on the facebookConnectionState, a different text is displayed. In the image the player did already connect with Facebook, thus he is shown information what he gains from this connection and when he should use the disconnect functionality.
  If the player connects with Facebook, the highscore progress and unlocked achievements are automatically posted to the timeline. These graph stories are visible to all of your player's friends and thus will bring you new downloads: If the player clicks the story in the mobile Facebook app, this will directly open your game!
  As Felgo Game Network internally uses the Score API (where the following image is taken from), this story is posted automatically on your player's timeline if he reaches a better highscore:
  If an achievement is unlocked, this is also posted in the player's timeline. The following image shows common stories that are visible in the player's Activity Log:
  If one of these graph stories is clicked on a mobile device, your app is started from the Facebook native application. If it is clicked in a web browser, the canvas page is shown which serves as an advertisement page for your game.
  Adding Facebook to your game with Felgo Game Network can be done in less than 5 minutes!
  Here I have prepared the steps required to add it to your game:
  If you do not have a game implemented yet, you can start with the sample code in <Qt5-SDK>/Examples/Felgo/examples/GameNetworkTestSimple for full source code with the Facebook connection, and follow the above tutorial to create your own Felgo Game Network game in the GameNetwork Web Dashboard and then create your own Facebook app for it.
  Players like to brag about their game progress and compare with their friends in their favorite game network. On iOS this clearly is Apple's Game Center which is pre-installed on every iOS device. Felgo Game Network allows your iOS players to compare each other both with their Game Center friends, but also with their friends on Android devices!
  In this step we will add support for Game Center on top of Felgo Game Network support! So you are able to support both game networks, with just a single API call!
  All you need to do for Game Center support, is to create a GameCenter item in your main qml file and connect it with the FelgoGameNetwork item like shown in this example:
  import Felgo 3.0 import QtQuick 2.0 GameWindow { // make sure to enable GameCenter for your application (developer.apple.com) GameCenter { id: gameCenter onPluginLoaded: authenticateLocalPlayer() } FelgoGameNetwork { id: gameNetwork // created in the Felgo Web Dashboard gameId: 5 secret: "abcdefg1234567890" gameNetworkView: myGameNetworkView facebookItem: facebook // by setting the gameCenterItem property, scores and achievements are also posted to GameCenter gameCenterItem: gameCenter } // the Scene will follow here }// GameWindow
  That's it! Felgo Game Network will handle the internal API calls for Game Center when you are calling reportScore(), unlockAchievement() or incrementAchievement() for the gameNetwork item. Sweet, isn't it? ;)
  In this lesson you've learned how to increase your game downloads and player engagement, by using Felgo Game Network together with Facebook and Game Center.
  If you have any questions about this lesson, just send us an email to support@felgo.com.
