Curious on a few things.
- How to make some parts of the sprite above the wire and some parts of the sprite behind the wire.
- What logics should be used, ie. colliders? raycasting?
- How to make sure the player dont jump from one place to the other?

Curious on a few things.

You can keep small colliders at the ends of the ring and the wire. I think with raycasting you might have to constantly keep checking if the ring ends overlapped with the wire.
I don’t quite understand what you mean by player jumping from one place to another.
