Help How to guarantee a rope will not go through a collider?

[lela_tabathy]

If I may hijack this thread, I‘m trying something similar where I‘m reducing the ropes length through Cursor, while the end is attached to a fixed point. I need to make sure the rope doesn‘t go through colliders along the way and basically stops the Cursor. Here‘s a sophisticated drawing, the first one shows the intended behaviour when the rope cursor is at the point where the rope shouldn’t shorten any further.

Any tips?
I‘m currently doing this by checking the rest length and not allowing further shortening that way. But that way I have to trial & error the min length and it‘s not very scalable.
