The
update()
method fetches the touch events and checks whether a “touch-up� event has
been registered. If so, it transforms the touch coordinates to the camera's coordinate system.
With these coordinates, it tests the various rectangles to decide what action to take.

The
present()
method does the same thing as the
MainMenuScreen.render()
method. We render
the background and buttons with texturing and blending where needed. Based on the current
settings, we decide which
TextureRegion
to use to render the three settings buttons.
