Game Programming Using Qt

Time for action – generating coins

The goal of the game we are trying to implement is to collect coins. We will spawn coins now and then in random locations of the scene.

Create a new QML Document and call it Coin.qml. In the editor, enter the following code:

Item {
  id: coin

  Rectangle {
    id: coinVisual
    color: "yellow"
    border.color: Qt.darker(color)
    border.width: 2
    width: 30; height: width
    radius: width/2
    anchors.centerIn: parent

    transform: Rotation {
      axis.y: 1

      NumberAnimation on angle {
        from: 0; to: 360
        loops: Animation.Infinite
        running: true
      }
    }
    Text {
      color: coinVisual.border.color
      anchors.centerIn: parent
      text: "1"
    }
  }
}

Next, open the document where the scene is defined and enter the following code somewhere in the scene definition:

Component { ...
