      //We load the image file of a new object:

      tomatoImage =

      new Bitmap(myAssembly.GetManifestResourceStream(

      myName_of_project + "." + "tomato.gif"));

      //We initialize an array of new objects and rectangles,

      //described around these objects:

      initialiseTomatoes();

      //We place new objects in an upper part of the screen:

      placeTomatoes();

      //We create and initialize a font for record of points:

      messageFont = new Font(FontFamily.GenericSansSerif, 10,

      FontStyle.Regular);

      //We reserve a rectangle on the screen

      //for record of points:

      messageRectangle = new Rectangle(0, 0,

      this.ClientSize.Width, scoreHeight);

      //We set the color of a brush for record of points:

      messageBrush = new SolidBrush(Color.Black);

      //We turn on the timer:

      timer1.Enabled = true;

      И наконец, вместо приведённого выше метода updatePositions записываем следующий метод, дополненный новым кодом для изменения координат, обнаружения столкновений объектов, уничтожения помидоров и подсчёта очков.
