I am trying to make a script regarding gravity,any help?

I am trying to make a script that enables a part to have its own gravity pull

In other words I am trying to make a part that is vertical and has a gravity pull that allows players to stand and move on that vertical part vertically

So any tips?I have tried reading the wiki article about gravity so still I am not sure about how to make it so I would appreciate it if you told me any other thing I need to know to make the script

You can use C-Framing to rotate the player model or you could make the wall a ladder and change the climbing animation into a vertically walking animation.

Hope This Helped!
