How could I accomplish this?

[Chrisy_RBX (Chrisy)]

I have a set of doors but want them to open automatically and slide round a cylinder.

Any ideas of how I could do this?

2 Options, CFrame tweening it around a pivot point which in this case should be located at the center of cylinder to achieve circular motion.

Or animate it using a rigged model with an AnimationController (more preferable) or humanoid.

Tween part around pivot point?

Oh yeah good point, the article in understanding CFrame math operations requires that you need to change two CFrame values at once in order to rotate around a hinge. hinge.CFrame = hinge.CFrame * CFrame.Angles(0, math.rad(1)*dt*60, 0) -- rotate the hinge door.CFrame = hinge.CFrame * offset -- apply offset to rotated hinge Luckily theres a trick I did in another post with a helmet which gets around this issue by creating an CFrame Instance value to change both the hinge CFrame and the CFrame …

I would just create a hidden part at the centre of the cylinder and use that as the door hinge. I’ve attached and .rbxl file where I’ve created a cylinder with door so you can check it out.
In the example I added a click detector to the door for opening/closing.

I’ll attempt to animate it. I will update further if this works.

Sorry for the late response.

Animating it worked perfectly.
Thanks!
