Why doesnt the player head rotate?

im not sure if this needs to be a server script fired by a local script or something but i wanted to try make a head rotation script that rotates to where ever the mouse is pointed and here is the script local script:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
while wait() do
	player.CharacterAdded:Connect(function(character)
		character.Head.Orientation = Vector3.new(mouse.hit.p)
	end)
end

after this failed i tried to rotate my head manually using the rotate tool and it instantly killed my character, how would i make this work without dying

mouse.hit.p is a position in 3D space. Orientation is a vector3 object, but it store degrees, 0, 90, 180..., so you cannot assign a position to a orientation.

you have to use CFrame(currentPosition, mousePointer) function to rotate your character, my code is like this

if character then
	-- I don't want to use mouse Y because I don't want character look at sky
	local direction = Vector3.new(mouse.Hit.p.X, character.HumanoidRootPart.Position.Y, mouse.Hit.p.Z)
	-- the if then below is for R15 and R6, if game is using R15, no need for second part
	if character:FindFirstChild("HumanoidRootPart") then
		character.HumanoidRootPart.CFrame = CFrame.new(character.HumanoidRootPart.Position, direction)
	else
		character.Torso.CFrame = CFrame.new(character.Torso.Position, direction)
	end
end
