I'm trying to get this part to follow the player, so far all of it works except the part wont rotate, why? (this is inside a tool)

while true do
	wait()
	if script.Parent.Parent:FindFirstChild("HumanoidRootPart") then
	script.Parent.Part.CFrame = script.Parent.Parent:FindFirstChild("HumanoidRootPart").CFrame+script.Parent.Parent:FindFirstChild("HumanoidRootPart").CFrame.lookVector*5
	local rot = script.Parent.Parent:FindFirstChild("HumanoidRootPart").CFrame:toEulerAnglesXYZ()	
	script.Parent.Part.CFrame = CFrame.new(rot+math.floor(script.Parent.Part.CFrame.X),math.floor(script.Parent.Part.CFrame.Y),math.floor(script.Parent.Part.CFrame.Z))
	end
end
