code: public void pressObject (SceneObject scobj)
      {
          int px = scobj.bounds.x + scobj.bounds.width/2;
          int py = scobj.bounds.y + scobj.bounds.height/2;
          handleObjectPressed(scobj, px, py);
      }
docs: Programmatically "click" a scene object. This results in a call to
  {@link #handleObjectPressed} with click coordinates in the center of the object.
