 Again, pressing both keys at once will cancel out and result in no rotation.
 The rotation is applied directly to the body's ``rotation`` property.

+To set the velocity, we use the ``Vector2.rotated()`` method, so that it points
 in the same direction as the body. ``rotated()`` is a useful vector function
 that you can use in many circumstances where you would otherwise need to apply
 trigonometric functions.
