How to rotate head (motor6d) away from camera within a 180 degree range?

Hi guys, today I’ve been tinkering around with head rotation with camera as a very nice piece of polish to add towards my rig. So far I have a script that replicates CFrame of a Motor6D’s (Neck’s) c0 to other players, but I don’t really know what to put in for the calculations of the rotation.

I want the head to rotate away from the camera within a 180 degree range, but so far most tutorials are adjusted for regular r6 rigs, and I’m not working with one here.

This is the closest I’ve gotten to the result so far, a gif showcasing another player’s head movement.

However, I want the head simply to move around it’s center, whilst not being able to turn 180 degrees like an owl, kind of like in this video (which I got the scripts from, with intent to modify them for my purposes): Server Side Head/Camera Movement (R6/R15) - Roblox (Remote Events and Tweening) - YouTube
How can I achieve this?

Here’s my client-side script so far, placed in starterCharacterScripts (Which handles the movement, server side script simply tells everyone else the cframe which is fired from this script):

local tweenService = game:GetService("TweenService")

local Camera = workspace.CurrentCamera
local Player = game.Players.LocalPlayer

local Character = Player.Character
local Root = Character:WaitForChild("HumanoidRootPart")
local Neck = Character:FindFirstChild("Neck", true)
local YOffset = Neck.C0.Y

local CFNew, CFAng = CFrame.new, CFrame.Angles
local asin = math.asin

game:GetService("RunService").RenderStepped:Connect(function()
    local CameraDirection = Root.CFrame:toObjectSpace(Camera.CFrame).lookVector
    if Neck then
		Neck.C0 = CFNew(0, YOffset, 0) * CFAng(3 * math.pi/2, 0, math.pi) * CFAng(0, 0, -asin(CameraDirection.x)) * CFAng(-asin(CameraDirection.y), 0, 0)
    end
end)

game.ReplicatedStorage.Remotes.Look.OnClientEvent:Connect(function(otherPlayer, neckCFrame)
	local Neck = otherPlayer.Character:FindFirstChild("Neck", true)
	
	if Neck then
		tweenService:Create(Neck, TweenInfo.new(.5, Enum.EasingStyle.Quad, Enum.EasingDirection.Out, 0, false, 0), {C0 = neckCFrame}):Play()
	end
end)

while wait(.2) do
	game.ReplicatedStorage.Remotes.Look:FireServer(Neck.C0)
end

i already made a head point to camera lookvector script:

local Plr = game.Players.LocalPlayer
local neck = Plr.Character.Torso.Neck
local camera = workspace.CurrentCamera

local hip = Plr.Character.Torso:WaitForChild("Right Hip")
local humanoid = Plr.Character.Humanoid

game:GetService("RunService").RenderStepped:Connect(function()
wait()
local theplace = Plr.Character.HumanoidRootPart.CFrame:toObjectSpace(camera.CFrame).lookVector

	local value = CFrame.new(0,1.025,0) * CFrame.Angles(math.asin(theplace.Y)+5,0,-math.asin(theplace.X)+84.75)
	
	neck.C0 = value
	
end)

although its only clientside and made for r6 you can try applying this kind of script to yours

I’m gonna try this out, I don’t know if it’ll work though since I need my object to rotate around it’s center. Will update you on result

this is what its supposed to look like before another unrelated script kicked in

Yeah it’s a bit closer to what I need, but as you can see in the gif near the end, I get this weird rotation forwards and backwards kind of. Any idea on how to make it purely rotate around the center, since I know the formula/calculation makes it so that it pivots around where the ‘neck’ is on an r6 model.

#6

if you want it to only rotate then replace the end with this:

	local value = CFrame.Angles(-math.asin(theplace.Y)+5,0,math.asin(theplace.X)+84.75)
	neck.C1 = value
	
end)

OMG! You’re a life saver! I’ve been struggling on this problem for about 3 hours now, since I can’t really grasp my head around CFrame rotation! Thank you so much.
