Time for action – improving the path of the sun

The task at hand is going to be to improve the animation of the sun so that it behaves in a more realistic way. We will do this by adjusting the animations so that the object moves over a curved path.

In our QML document, replace the previous vertical animation with the following one:

SequentialAnimation {
  NumberAnimation {
    target: sun
    property: "y"
    from: root.height+sunVisual.height
    to: root.height-270
    duration: dayLength/2
    easing.type: Easing.OutCubic
  }
  NumberAnimation {
    target: sun
    property: "y"
    to: root.height+sunVisual.height
    duration: dayLength/2
    easing.type: Easing.InCubic
  }

  running: true
}
