I’m pretty sure that’s exactly what I’m after! The only thing is the semi circle isn’t a flat surface, so when the cylinder rolls I feel like it wouldn’t roll along the edges of the semi circle? Thanks very much for sharing that script with me though and would love to know if you ever manage to figure it out 🙂
Hi Filip, I attached the image below, So as the semi circle like rotates below the cylinder moves in the opposite direction but stays attached to the surface of the semi circle, hope that makes sense!
