The angle elements are numeric constants representing the angle (direction) expressed in radian (the perigon, 360 degrees is 2*pi, i.e. approximately 6.28). The angle elements can be used e.g. as a goniometric function parameter or a parameter for setting the sprite direction (e.g. of Peter or Lucy).
