local part = script.Parent while true do local Orotate = script.Parent.Orientation wait(.8) part.Orientation = Vector3.new(0,Orotate - 1, 0) end`
Assuming the ` after your end is just a typo in your pasting code, here's what I assume.
local part = script.Parent while true do wait(.8) part.Orientation = Vector3.new(part.Orientation.X,part.Orientation.Y - 1, part.Orientation.Z) end
That code will move it to the current orientation minus the Y orientation.
