Game Menu, Player look at mouse

Okay guys this is gonna be a long one as I try to explain what I want.

So basically I have my game menu which shows the player. I want the player’s head to follow the mouse wherever it is on the screen.

Example: (Ignore the horrible drawing)

Anyways that curved line represents a rotation, and the arrow represents where I want it to look. However I want the look to be natural, so not just the head looking there (Although just the head is perfectly fine)

I honestly haven’t done anything other than screw it up multiple times because I have no idea where to start with this. An explanation with code would be much appreciated, I want to learn the code not just copy it!

Although this won’t probably achieve the effect you’re looking for, it’s a pretty good example and start, indeed, if you modify this video’s code with the Mouse position instead of the Camera direction you could probably achieve the head movement.

Issue is that I don’t know how to use the mouses position in a 3D space.

uh this article helped me Dragging objects with the mouse
it knida explains the mouse positions in 3d

Thanks I’ll work on it and update if it works!

I forgot where I got this script on the forum but here it is:

local RunService = game:GetService("RunService")

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

	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)
