Make part follow another part

[NiubbosAttNum3 (Niu)]

Hi
I want to make sphere A follow sphere B and when it gets too close it moves back. I never worked with stuff like that before and I don’t know how to do it, after trying different tutorials and articles.
(sphere A is anchored)

Maybe try this thread.

How would I make a part follow another part when it moves, but not have the other part follow this part when it moves?

I want to make a sort of one way weld, when part 1 moves part 2 moves with it, but when part 2 moves part 1 doesn’t move with it. Doing this with a loop (constantly changing part 1’s position to part 2’s position) is too slow and part 1 lags behind.

Tried it, but it seems laggy. And it has to be un anchored. I was looking more for something to just change the position of the sphere A every frame.
