Hi,

I’m currently porting a game made in QML for Meego to Felgo. Most things works fine but I have some issues with the “card flip”-animations that were implemented using  Rotation element around y axis. I made a small test application to test the Rotation element and it seems to work fine to rotate an object around z axis, but not around x or y.

Here is my code:

import VPlay 1.0
import QtQuick 1.1

GameWindow {
    activeScene: scene
    width: 640
    height: 960
    
    Scene {
        id: scene
        width: 320
        height: 480
        
        Rectangle {
            anchors.fill: parent
            color: "black"
        }

        Rectangle{
            id: rectangle
            width: 100
            height: 100
            color: "red"
            anchors.centerIn: parent
            transform:  Rotation {
                id: rotation
                origin.x: rectangle.width/2
                origin.y: rectangle.height/2
                axis.x: 0; axis.y: 1; axis.z: 0     // set axis.y to 1 to rotate around y-axis
                angle: 45    // the default angle
            }
        }

    }
}

Will this be fixed anytime soon?

Thank you!

Hi Matthias,

I’m sorry, but with our current renderer flipping is not possible. You could create the animation in any program and save the single sprite frames into a sprite sheet, and then play the animation sequence like an animated gif. Would this be sufficient for your use-case? Another workaround would be to animate the xScale of the sprite from 1 to 0, then change the sprite image, and then animate the xScale from 0 to 1.

Cheers, Chris

In my case using sprites would not be practical. Animating the width will work fine in my case even if the effect is not as nice as the QML flip rotation. Thanx for the input.
