I'm working on a FPS engine/framework. At the moment I'm stuck on the camera tracking arms part. I've got the arms to follow where you look, up and down, though they don't do it perfectly. I need them to dynamically raise and lower position, according to the how high or low you're looking. I can't seem to find a proper equation to do this though. Can anyone help me?

function WeldArms(Weapon)
	if Weapon == nil then Weapon = "DebugGun" end
	game.Players.LocalPlayer.Character["Left Arm"]:Destroy()
	game.Players.LocalPlayer.Character["Right Arm"]:Destroy()
	local Arms = game.ReplicatedStorage.Arms:Clone()
	local LArm = Instance.new("Weld")
	local RArm = Instance.new("Weld")
	RArm.Name = "RArm"
	LArm.Name = "LArm"
	LArm.Part0 = game.Players.LocalPlayer.Character.Head
	LArm.Part1 = Arms["Left Arm"]
	RArm.Part0 = game.Players.LocalPlayer.Character.Head
	RArm.Part1 = Arms["Right Arm"]
	LArm.C0 = CFrame.new(-1,-0.5,1)
	RArm.C0 = CFrame.new(1,-0.5,0.2)
	Arms.Parent = game.Workspace.CurrentCamera
	LArm.Parent = Arms
	RArm.Parent = Arms
--Welding Weapon--
	local Wep = Guns[Weapon].Directory:Clone()
	local WepWeld = Instance.new("Weld")
	WepWeld.Name = "WeaponWeld"	
	WepWeld.Part0 = Arms[Guns[Weapon].MainArm]
	WepWeld.Part1 = Wep[Guns[Weapon].MainPart]
	WepWeld.C0 = CFrame.new(-1,-0.5,0)
	WepWeld.Parent = Wep
	Wep.Parent = game.Workspace.CurrentCamera
--Camera Follow--
local function updateGunPos()
	if Guns[Weapon].MainArm == "Left Arm" then
		LArm.C0 = CFrame.new(-1, -1+game.Workspace.CurrentCamera.CoordinateFrame.lookVector.Y,-2)*CFrame.Angles(game.Workspace.CurrentCamera.CoordinateFrame.lookVector.Y,math.rad(90),math.rad(180))
	end	
end
while wait(.05) do
	updateGunPos()
end
end
