Making head movement script compatible with non mouse devices

Help and Feedback Scripting Support
#1

I want to make this script also compatible with mobile players, since this script focuses on the mouse position rather than the camera direction
when on mobile, the head only tilts when the screen is touched, it does not follow camera direction
i have tried to look for camera related things to make it face the camera direction rather than the mouse
After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!
heres the script

local RunService = game:GetService("RunService")
local tweenService = game:GetService("TweenService")
local Player = game.Players.LocalPlayer
local PlayerMouse = Player:GetMouse()

local Camera = workspace.CurrentCamera

local Character = Player.Character or Player.CharacterAdded:Wait()
local Head = Character:WaitForChild("Head")
local Neck = Head:WaitForChild("Neck")

local Torso = Character:WaitForChild("UpperTorso")
local Waist = Torso:WaitForChild("Waist")

local Humanoid = Character:WaitForChild("Humanoid")
local HumanoidRootPart = Character:WaitForChild("HumanoidRootPart")

local NeckOriginC0 = Neck.C0
local WaistOriginC0 = Waist.C0

Neck.MaxVelocity = 1/3

RunService.RenderStepped:Connect(function() 
	local CameraCFrame = Camera.CoordinateFrame
	
	if Character:FindFirstChild("UpperTorso") and Character:FindFirstChild("Head") then
		local TorsoLookVector = Torso.CFrame.lookVector
		local HeadPosition = Head.CFrame.p
		
		if Neck and Waist then
			if Camera.CameraSubject:IsDescendantOf(Character) or Camera.CameraSubject:IsDescendantOf(Player) then
				local Point = PlayerMouse.Hit.p
				
				local Distance = (Head.CFrame.p - Point).magnitude
				local Difference = Head.CFrame.Y - Point.Y
				
				Neck.C0 = Neck.C0:lerp(NeckOriginC0 * CFrame.Angles(-(math.atan(Difference / Distance) * 0.5), (((HeadPosition - Point).Unit):Cross(TorsoLookVector)).Y * 1, 0), 0.5 / 2)
				Waist.C0 = Waist.C0:lerp(WaistOriginC0 * CFrame.Angles(-(math.atan(Difference / Distance) * 0.5), (((HeadPosition - Point).Unit):Cross(TorsoLookVector)).Y * 0.5, 0), 0.5 / 2)
				
			end
		end
	end	
end)

game.ReplicatedStorage.Look.OnClientEvent:Connect(function(otherPlayer, neckCFrame, WaistCFrame)
	local Neck = otherPlayer.Character:FindFirstChild("Neck", true)
	local Waist = otherPlayer.Character:FindFirstChild("Waist", true)

	if Neck then
		tweenService:Create(Neck, TweenInfo.new(.5, Enum.EasingStyle.Quad, Enum.EasingDirection.Out, 0, false, 0), {C0 = neckCFrame}):Play()
		tweenService:Create(Waist, TweenInfo.new(.5, Enum.EasingStyle.Quad, Enum.EasingDirection.Out, 0, false, 0), {C0 = WaistCFrame}):Play()
	end
end)

while wait(0.2) do
	game.ReplicatedStorage.Look:FireServer(Neck.C0,Waist.C0)
end

server script:

game.ReplicatedStorage.Look.OnServerEvent:Connect(function(player, neckCFrame, WaistCFrame)
	for key, value in pairs(game.Players:GetChildren()) do
		if value ~= player and (value.Character.Head.Position - player.Character.Head.Position).Magnitude < 10 then
			game.ReplicatedStorage.Look:FireClient(value, player, neckCFrame, WaistCFrame)
		end
	end
end)
