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!

What I’m wanting to do is have a cylindrical shape move in relation to a rotating semi circle beneath it. Essentially as the semi circle moves below, the cylinder stays in contact and moves how it would if they were both solid shapes in real life.
Super confused as it involves rotation as well as positional movement and I’m really bad at math…… Read more
