How would I make a part follow along a RopeConstraint? Is there a way to get the math that’s used internally?

I want to make a part start at the Attachment0 then move along the ropes curve to the Attachment1.

If it helps your googling, they’re probably modeling the shape with something called a “catenary curve”. Also, for the purposes of those equations, the gravity constant in roblox is 196 studs/sec^2.

I might take a crack at this later, but that might get you somewhere.

You could also probably approximate it with a parabola (or even try euler integration or something) – and maybe the devs did too.

edit: here is a fun desmos I found. Turn on equation 6 and you can see some of the math. It’s overkill to do this, I think. I would probably approximate it.

i believe an easy way to do it would be to create a quadratic beziers curve

point 0 of the beziers curve being attachment0

point 2 of the beziers curve being attachment 1

and then you could play with the maths a bit to position point 1 so that the end curve is good enough

This is years later. But did you figure this out by any chance?
