Sorry I was away from the forum for a while and wasn’t getting thread notifications for some reason.
So it sounds like you want this to behave as though you are dragging a semi-sticky object, right? Like a magnet dragging a larger piece of metal? If you bump into something do you want to become “dropped”? Like how would you handle sliding around a corner and not allowing room for the thing you are pulling? Give me an idea of how you would want that to work.
If it turns out you only need an answer to this question and don’t want to bother with a different solution let me know. I can help you there as well.
