Trying to make non viewmodel not move head

largrgy · April 20, 2026, 9:25pm

so i found this local script and im trying to only make the arms move and not the head

as you can see, the head moves very weirdly which i don’t like

--R6 Only
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remote = ReplicatedStorage:WaitForChild("Look")
local camera = workspace.CurrentCamera
local character = script.Parent

local torso = character:WaitForChild("Torso")
local head = character:WaitForChild("Head")

local rightShoulder = torso:WaitForChild("Right Shoulder")
local leftShoulder = torso:WaitForChild("Left Shoulder")
local neck = torso:WaitForChild("Neck")

local rightShoulderCopy = Instance.new("Motor6D")
rightShoulderCopy.C0 = CFrame.new(1.5, -1, 0) * rightShoulder.C0.Rotation
rightShoulderCopy.C1 = CFrame.new(0, .5, 0) * rightShoulder.C1.Rotation
rightShoulderCopy.Part1 = rightShoulder.Part1
rightShoulderCopy.Name = "RightShoulderCopy"
rightShoulderCopy.Archivable = false
rightShoulderCopy.Part0 = head
rightShoulderCopy.Parent = head

local leftShoulderCopy = Instance.new("Motor6D")
leftShoulderCopy.C0 = CFrame.new(-1.5, -1, 0) * leftShoulder.C0.Rotation
leftShoulderCopy.C1 = CFrame.new(0, .5, 0) * leftShoulder.C1.Rotation
leftShoulderCopy.Part1 = leftShoulder.Part1
leftShoulderCopy.Name = "LeftShoulderCopy"
leftShoulderCopy.Archivable = false
leftShoulderCopy.Part0 = head
leftShoulderCopy.Parent = head

rightShoulder.Enabled = false
leftShoulder.Enabled = false

RunService.RenderStepped:Connect(function()
	local lookVector = (camera.Focus.Position - camera.CFrame.Position).Unit


	neck.C0 = CFrame.new(0, 1.5, 0) * CFrame.Angles(math.asin(lookVector.Y), 0, 0)
	neck.C1 = CFrame.new()

	remote:FireServer(lookVector)
end)

RunService.Stepped:Connect(function()
	rightShoulderCopy.Transform = rightShoulder.Transform
	leftShoulderCopy.Transform = leftShoulder.Transform
end)

workspace:GetPropertyChangedSignal("CurrentCamera"):Connect(function()
	local _camera = workspace.CurrentCamera
	if _camera then
		camera = _camera
	end
end)

Remove:

neck.C0 = CFrame.new(0, 1.5, 0) * CFrame.Angles(math.asin(lookVector.Y), 0, 0)
neck.C1 = CFrame.new()

largrgy · April 20, 2026, 9:34pm

it doesn’t make meh arms move anymore

Oaziik · April 20, 2026, 9:34pm

Do you have the ServerScript that the remote even triggers?

largrgy · April 20, 2026, 9:35pm

yeah i do but i remove the neckthing that makes it do that

Oaziik · April 20, 2026, 9:35pm

So did it work then? …
Confused…

largrgy · April 20, 2026, 9:37pm

nah heres a video on how it looks now

Oaziik · April 20, 2026, 9:38pm

Send the server script, pleaaaase?

largrgy · April 20, 2026, 9:38pm

local ReplicatedStorage = game:GetService(“ReplicatedStorage”)
local remote = ReplicatedStorage:WaitForChild(“Look”)

remote.OnServerEvent:Connect(function(player, lookVector)
local character = player.Character
if not character then return end

local torso = character:FindFirstChild("Torso")
if not torso then return end

local neck = torso:FindFirstChild("Neck")
if not neck then return end

-- Apply for everyone
--neck.C0 = CFrame.new(0, 1.5, 0) * CFrame.Angles(math.asin(lookVector.Y), 0, 0)
--neck.C1 = CFrame.new()

end)

Oaziik · April 20, 2026, 9:39pm

Are there parts of the script unposted? I can’t see where the changes to the Arms get their values etc.

largrgy · April 20, 2026, 9:41pm

heres all of the scripts

local script

--R6 Only
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remote = ReplicatedStorage:WaitForChild("Look")
local camera = workspace.CurrentCamera
local character = script.Parent

local torso = character:WaitForChild("Torso")
local head = character:WaitForChild("Head")

local rightShoulder = torso:WaitForChild("Right Shoulder")
local leftShoulder = torso:WaitForChild("Left Shoulder")
local neck = torso:WaitForChild("Neck")

local rightShoulderCopy = Instance.new("Motor6D")
rightShoulderCopy.C0 = CFrame.new(1.5, -1, 0) * rightShoulder.C0.Rotation
rightShoulderCopy.C1 = CFrame.new(0, .5, 0) * rightShoulder.C1.Rotation
rightShoulderCopy.Part1 = rightShoulder.Part1
rightShoulderCopy.Name = "RightShoulderCopy"
rightShoulderCopy.Archivable = false
rightShoulderCopy.Part0 = head
rightShoulderCopy.Parent = head

local leftShoulderCopy = Instance.new("Motor6D")
leftShoulderCopy.C0 = CFrame.new(-1.5, -1, 0) * leftShoulder.C0.Rotation
leftShoulderCopy.C1 = CFrame.new(0, .5, 0) * leftShoulder.C1.Rotation
leftShoulderCopy.Part1 = leftShoulder.Part1
leftShoulderCopy.Name = "LeftShoulderCopy"
leftShoulderCopy.Archivable = false
leftShoulderCopy.Part0 = head
leftShoulderCopy.Parent = head

rightShoulder.Enabled = false
leftShoulder.Enabled = false

RunService.RenderStepped:Connect(function()
	local lookVector = (camera.Focus.Position - camera.CFrame.Position).Unit


	neck.C0 = CFrame.new(0, 1.5, 0) * CFrame.Angles(math.asin(lookVector.Y), 0, 0)
	neck.C1 = CFrame.new()

	remote:FireServer(lookVector)
end)

RunService.Stepped:Connect(function()
	rightShoulderCopy.Transform = rightShoulder.Transform
	leftShoulderCopy.Transform = leftShoulder.Transform
end)

workspace:GetPropertyChangedSignal("CurrentCamera"):Connect(function()
	local _camera = workspace.CurrentCamera
	if _camera then
		camera = _camera
	end
end)

serverscript

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remote = ReplicatedStorage:WaitForChild("Look")

remote.OnServerEvent:Connect(function(player, lookVector)
	local character = player.Character
	if not character then return end

	local torso = character:FindFirstChild("Torso")
	if not torso then return end

	local neck = torso:FindFirstChild("Neck")
	if not neck then return end

	-- Apply for everyone
	neck.C0 = CFrame.new(0, 1.5, 0) * CFrame.Angles(math.asin(lookVector.Y), 0, 0)
	neck.C1 = CFrame.new()
end)

thats everything i used for it

Oaziik · April 20, 2026, 9:44pm

I think the arms move as a result of the Gun that you equipped in the first video, not the local script provided? I think it’s tied to your Neck C0, C1.

Can you provided the script for the gun? It may be a case of making a Pseudo value to mimic to C0 without changing the neck.

largrgy · April 20, 2026, 9:47pm

wait what script of the gun, also the arms move without any tools being equipped

Oaziik · April 20, 2026, 9:54pm

The only thing I can think is that your free models are contradicting eachother.

So your LocalScript disables the joints in the character so that false joints can be used - But then when equipping the gun this function doesn’t work anymore.

Basically I think the server side of the gun is contradicting the client side of the script provided.

largrgy · April 20, 2026, 9:57pm

wait waht im a bit confused on wuh you said

srtaub · April 22, 2026, 6:46pm

I think I got it to work, try this code:

--R6 Only
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remote = ReplicatedStorage:WaitForChild("Look")
local camera = workspace.CurrentCamera
local character = script.Parent

local torso = character:WaitForChild("Torso")
local head = character:WaitForChild("Head")

local rightShoulder = torso:WaitForChild("Right Shoulder")
local leftShoulder = torso:WaitForChild("Left Shoulder")

local rightShoulderOriginalC0 = rightShoulder.C0
local leftShoulderOriginalC0 = leftShoulder.C0

RunService.RenderStepped:Connect(function()
	local origin = torso.CFrame
	
	local headFromOrigin = head.CFrame * origin:Inverse()
	
	local lookVector = (camera.Focus.Position - camera.CFrame.Position).Unit
	local angle = CFrame.Angles(math.asin(lookVector.Y), 0, 0)
	
	local headToRightArm = (headFromOrigin:Inverse() * rightShoulderOriginalC0)
	rightShoulder.C0 = headFromOrigin * angle * headToRightArm
	
	local headToLeftArm = (headFromOrigin:Inverse() * leftShoulderOriginalC0)
	leftShoulder.C0 = headFromOrigin * angle * headToLeftArm
	
	remote:FireServer(lookVector)
end)

workspace:GetPropertyChangedSignal("CurrentCamera"):Connect(function()
	local _camera = workspace.CurrentCamera
	if _camera then
		camera = _camera
	end
end)

Now the arms should move without the head moving.

I won’t go through explaining how it works right now since it’s a lot to write, but if you want me to (and this solves your problem), I can.

I hope this helps!

largrgy · April 22, 2026, 7:48pm

this is how it looks now

LOL its VERY weird heh

srtaub · April 22, 2026, 8:51pm

Maybe mine isn’t working right with your other systems lol.
Here another one to try, that should hopefully work better with your other systems:

--R6 Only
local RunService = game:GetService("RunService")
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local remote = ReplicatedStorage:WaitForChild("Look")
local camera = workspace.CurrentCamera
local character = script.Parent

local torso = character:WaitForChild("Torso")
local head = character:WaitForChild("Head")

local rightShoulder = torso:WaitForChild("Right Shoulder")
local leftShoulder = torso:WaitForChild("Left Shoulder")
local neck = torso:WaitForChild("Neck")

local armPivotPart = Instance.new("Part")
armPivotPart.Name = "ArmPivotPart"
armPivotPart.Size = Vector3.new(1, 1, 1)
armPivotPart.Transparency = 1
armPivotPart.CanCollide = false
armPivotPart.CanTouch = false
armPivotPart.CanQuery = false
armPivotPart.Parent = character

local armPivotJoint = Instance.new("Motor6D")
armPivotJoint.Part0 = armPivotPart
armPivotJoint.Part1 = head
armPivotJoint.Name = "ArmPivotJoint"
armPivotJoint.Parent = armPivotPart

local rightShoulderCopy = Instance.new("Motor6D")
rightShoulderCopy.C0 = CFrame.new(1.5, -1, 0) * rightShoulder.C0.Rotation
rightShoulderCopy.C1 = CFrame.new(0, .5, 0) * rightShoulder.C1.Rotation
rightShoulderCopy.Part1 = rightShoulder.Part1
rightShoulderCopy.Name = "RightShoulderCopy"
rightShoulderCopy.Archivable = false
rightShoulderCopy.Part0 = armPivotPart
rightShoulderCopy.Parent = head

local leftShoulderCopy = Instance.new("Motor6D")
leftShoulderCopy.C0 = CFrame.new(-1.5, -1, 0) * leftShoulder.C0.Rotation
leftShoulderCopy.C1 = CFrame.new(0, .5, 0) * leftShoulder.C1.Rotation
leftShoulderCopy.Part1 = leftShoulder.Part1
leftShoulderCopy.Name = "LeftShoulderCopy"
leftShoulderCopy.Archivable = false
leftShoulderCopy.Part0 = armPivotPart
leftShoulderCopy.Parent = head

rightShoulder.Enabled = false
leftShoulder.Enabled = false

RunService.RenderStepped:Connect(function()
	local lookVector = (camera.Focus.Position - camera.CFrame.Position).Unit

	armPivotJoint.C0 =  CFrame.Angles(math.asin(lookVector.Y), math.rad(180), 0)
	armPivotJoint.C1 = CFrame.new()

	remote:FireServer(lookVector)
end)

RunService.Stepped:Connect(function()
	rightShoulderCopy.Transform = rightShoulder.Transform
	leftShoulderCopy.Transform = leftShoulder.Transform
end)

workspace:GetPropertyChangedSignal("CurrentCamera"):Connect(function()
	local _camera = workspace.CurrentCamera
	if _camera then
		camera = _camera
	end
end)

largrgy · April 22, 2026, 9:07pm

errr it does this noww…

also i sorta want a system like this,

so that i dont have to do viewmodels, like i want the arms to go up and down but not be raised or lowered when your in first person

srtaub · April 22, 2026, 9:42pm

Maybe try switching this line:

armPivotJoint.C0 =  CFrame.Angles(math.asin(lookVector.Y), math.rad(180), 0)

to this:

armPivotJoint.C0 =  CFrame.Angles(math.asin(lookVector.Y), 0, 0)
