Move a sprite from its current position by the specified number of pixels. Motion will be limited to the current screen. Optionally the sprite may be rotated or scaled by defining optional the rrotate_expr and scale_expression parameters. The degree rotate_expression is measured in radians. Rotation and scaling are relative to the previous state of the sprite.
