    I’m trying to build the Flappy Bird tutorial that was posted yesterday. Unfortunately, it doesn’t build with the Felgo Starter edition. For example it uses the property mirrorY from SingleSpriteFromFile which was introduced in v1.5.1. According to, there would be updates about every month, but apparently we’re still stuck with v1.5.0, which was released almost half a year ago. When will there be a new update so that we can at least build the tutorials without problems?




    I was able to build it using daily build but its crashes on startup

    before crash it shows in the log:

    <style type=”text/css”><!–
    p, li { white-space: pre-wrap; }
    –></style>Cocos2DWrapper: applicationDidFinishLaunching()

    file:///home/vladest/development/FlappyBird/qml/FlappyBirdMain.qml:83:3: Type VPlayGameNetworkScene unavailable

    VPlayGameNetworkScene {


    file:///home/vladest/development/FlappyBird/qml/scenes/VPlayGameNetworkScene.qml:17:5: Cannot assign to non-existent property “showAchievementsHeaderIcon”

    showAchievementsHeaderIcon: false


    WARNING: VPlayApplication: no GameWindow item found, so could not set the rootGameWindow contextProperty as well!

    Update cocosRenderer size to qmlViewer size: QSize(640, 480)

    the next major update will be Felgo v2.0 which brings Qt 5 support. As we cannot give a precise date when we will be able to release it, we now allow you to access daily builds until this update is released! You can start the Felgo SDK Maintenance Tool and use daily builds now. 🙂


    Regarding the build issue: this will be fixed tomorrow when we release daily build v1.5.5. Until then, please comment the property binding of showAchievementsHeaderIcon and it will run.





    It works now.

    Thanks for the quick solution!
