Flying around an edge of a Cube
So the player drags and releases object (red circle) like in angry birds. On all 4 sides of the cube the object follows the flat surface of the cube (imagine top and bottom of the cube are infinitely long). When the red circle reaches an edge it should fly within a curve (red line) to the next side of the cube based on its direction and velocity. To put it simple it is like in Mario Odyssey where Pokio (The bird with the long spike) can fly around edges.
My problem is that I do not know how to get the red circle from one side to the other. I used raycast, gravity and bezier curves but nothing worked out for me.
