<p>Indicates the rotation of the Graphics, in degrees, from its original orientation. Values from 0 to 180 represent clockwise rotation; values from 0 to -180 represent counterclockwise rotation.
Values outside this range are added to or subtracted from 360 to obtain a value within the range. For example, the statement player.angle = 450 is the same as player.angle = 90.
If you wish to work in radians instead of degrees use the property Sprite.rotation instead.</p>
