    Default Rotation Animation doesn't proceed after following animation restart

    Hi All,
    I am a new in QML area but with years of experience in C++ but lately I hit an issue with Rotation Animation after I restarted animation
    of rotating and bouncing ball.
    After app is started the ball correctly moves, rotates and bounces. But after I click the ball to restart the animation the ball moves, bounces like before but does not rotate. Is it anything missed in the code below. The code is taken from online book Qt5 cadaques. Is anything missed or is it not found yet bug in Qt QML?

    import QtQuick 2.2
    import QtQuick.Window 2.1

    Window {
    visible: true
    width: root.width
    height: root.height

    Image {
    id: root
    width: 480
    height: 350

    property int duration: 3000

    Rectangle {
    id: sky
    width: parent.width
    height: 200
    gradient: Gradient {
    GradientStop { position: 0.0; color: "#0080FF"}
    GradientStop { position: 1.0; color: "#66CCFF"}
    }
    }

    Rectangle {
    id: ground
    anchors.top: sky.bottom
    anchors.bottom: root.bottom
    width: parent.width
    gradient: Gradient {
    GradientStop { position: 0.0; color: "#00FF00"}
    GradientStop { position: 1.0; color: "#00803F"}
    }
    }
    }

    Image {
    id: ball
    x: 20; y: 240
    rotation: 0
    source: "assets/Soccer_ball.png"

    MouseArea {
    anchors.fill: parent
    onClicked: {
    ball.x = 20; ball.y = 240
    anim.restart()
    }
    }
    }

    ParallelAnimation {
    id: anim

    SequentialAnimation {

    NumberAnimation {
    target : ball
    properties: "y"
    to: 20
    duration: root.duration * 0.4
    easing.type: Easing.OutCirc
    }

    NumberAnimation {
    target: ball
    properties: "y"
    to: 240
    duration: root.duration * 0.6
    easing.type: Easing.OutBounce
    }
    }

    NumberAnimation {
    target: ball
    properties: "x"
    to: 400
    duration: root.duration
    }

    RotationAnimation {
    target: ball
    properties: "rotation"
    to: 720
    duration: root.duration * 1.1
    }
    }
    }

    Default Re: Rotation Animation doesn't proceed after following animation restart

    I'd say because the rotation value is not reset on mouse click.

    Cheers,

    Yes exactly. I found the solution before entered the thread again. Sometimes a man is blind.
