RenderStepped not working?

Hello! Thanks for your answer. However I don’t really understand some parts in the first code :sweat_smile:
Could you please explain this part

Is the variable timeSpent used for checking how much time is spent on moving the part?

local MOVE_30_STUDS_TIME = 120 * 1 / 60 -- couldn't you just assign 30 to this variable?
if timeSpent >= 2 * MOVE_30_STUDS_TIME then -- what is this checking for?
		part.CFrame = originalCf
		conn:Disconnect()
	end
