Yep, you heard the title.
How do i make a rotating part (a.k.a rotating donut)? Reference here:
This is the script that doesn't make the part carry me around just in case if you need it:
while true do script.Parent.CFrame = script.Parent.CFrame * CFrame.fromEulerAnglesXYZ(-0.01,0,0.0,0) wait() end
Use RotVelocity! (only used if unanchored)
