The direction of Lucy element represents the direction of Lucy after being rotated, expressed in radian (The perigon, 360 degrees, corresponding approximately to 6.28). The element can be treated as a normal numeric variable. By using it in a numeric term Lucy's current direction can be found out. By using the element as a command the direction of Lucy can be set. In case a preceding command to step or to shift to a specified coordinate has been given Lucy will first finish the shift before being rotated.
