Just press the green flag to see the wheel go. The main wheel (Sprite1) is a little bit crudely drawn. Match the size of the sprite with the variable 'Radius'. Wheel is centered on 0,0 to simplify the maths Carriages are clones of Sprite2. Position is calculated by using the radius and angle of the wheel. Each one has a different offset angle. Legs just sit there in Sprite3
