Attempt to index nil with 'WaitForChild'

Hello! I’m trying to make it so the players head is following the players camera but I’m getting an error saying attempt to index nil with ‘WaitForChild’ on line 6.

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
		if Character.Humanoid.RigType == Enum.HumanoidRigType.R15 then
			Neck.C0 = CFNew(0, YOffset, 0) * CFAng(0, -asin(CameraDirection.x), 0) * CFAng(asin(CameraDirection.y), 0, 0)
		elseif Character.Humanoid.RigType == Enum.HumanoidRigType.R6 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
end)

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

Try

local Camera = workspace.CurrentCamera
local Player = game:GetService("Players").LocalPlayer

local Character = Player.Character or Player.CharacterAdded:Wait() -- if we don't find the character we wait for it to load
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
		if Character.Humanoid.RigType == Enum.HumanoidRigType.R15 then
			Neck.C0 = CFNew(0, YOffset, 0) * CFAng(0, -asin(CameraDirection.x), 0) * CFAng(asin(CameraDirection.y), 0, 0)
		elseif Character.Humanoid.RigType == Enum.HumanoidRigType.R6 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
end)

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

The script works but It’s only client sided. Is there a way to make it server sided?

#4

I assume that’s what game.ReplicatedStorage.Look:FireServer(Neck.C0) is there for, do you have a server side script connected to that remote event?

#5

Yeah I do

game.ReplicatedStorage.Look.OnServerEvent:Connect(function(player, neckCFrame)
	for key, value in pairs(game.Players:GetChildren()) do
		if value ~= player and (value.Character.Head.Position - player.Character.Head.Position).Magnitude < 50 then
			game.ReplicatedStorage.Look:FireClient(value, player, neckCFrame)
			
		end
	end
end)

Seems like it should all be working then. Unless you know of any errors on the client side of Look.OnServerEvent. Did you write these scripts? You are probably meant to put the first script into StarterCharacterScripts

No I didn’t write these scripts I used this: Server Side Head/Camera Movement (R6/R15) - Roblox (Remote Events and Tweening) - YouTube
And they’re in starter character scripts

Here is the place file for that
headMovement.rbxl (31.1 KB)

and here is the code
starter character scripts

local tweenService = game:GetService("TweenService")

local Camera = workspace.CurrentCamera
local Player = game:GetService("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
		if Character.Humanoid.RigType == Enum.HumanoidRigType.R15 then
        	Neck.C0 = CFNew(0, YOffset, 0) * CFAng(0, -asin(CameraDirection.x), 0) * CFAng(asin(CameraDirection.y), 0, 0)
		elseif Character.Humanoid.RigType == Enum.HumanoidRigType.R6 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
end)

game.ReplicatedStorage.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 task.wait(1) do
	game.ReplicatedStorage.Look:FireServer(Neck.C0)
end
