Realistic Yo-Yo (Set Up) - all instructions on screen This simulation of a Yo-Yo, whilst far from perfect, is reasonably realistic. To simulate continuous spinning while the Yo-Yo is moving means we need to save the current direction before moving, and to restore it when movement is complete. The String is drawn by the Pen by continually redrawing a line between the Hand and the Yo-Yo.
