Cframe.Angles() not setting Y to 0 properly

I’m trying to make a HeadMovement system specifically for First-Person. I’m trying to set the neck joint orientation to the cameras orientation. Its working great in Third-Person if the body’s Y axis (Rotation) isn’t changing, but when i go in First-Person if i look behind me my head turns 180 degrees. This does look pretty funny but its not ideal for what i’m trying to do.
Script: (Server, Local isn’t important)

local event = script.CameraPos
local char = script.Parent
local neck = char:WaitForChild("Head").Neck
local ts = game:GetService("TweenService")
local tsinfo = TweenInfo.new(0.2,Enum.EasingStyle.Sine)

script.CameraPos.OnServerEvent:Connect(function(plr,cf)
	local sx, sy, sz, m00, m01, m02, m10, m11, m12, m20, m21, m22 = cf:GetComponents()

	local X = math.atan2(-m12, m22)

	local Y = math.asin(m02)

	local Z = math.atan2(-m01, m00)
	
	--neck.C0 = CFrame.Angles(X,0,Z) + neck.C0.Position
	ts:Create(neck,tsinfo,{C0 = CFrame.Angles(X,0,Z) + neck.C0.Position}):Play() -- MOST LIKELY WHERE THE PROBLEM IS!!
end)

I’ll be glad if this could get fixed.

Also the value “cf” is the camera’s full CFrame.

#3

from what i’ve picked up after reading and i am guessing, does it move because the whole body is rotating in first-person and then the head rotates also? now, i could be wrong but is that maybe the case?

i would update it to set the position to be relative to the HumanoidRootPart if that is the cause.

#4

Yes, its rotating relative from the Hrp’s rotation. I was also thinking that. Ill try code that. Ill update over more problems.

May be the most stupid fix but it works, and i cant think of anything else.

Updated Code:

local event = script.CameraPos
local char = script.Parent
local neck = char:WaitForChild("Head").Neck
local ts = game:GetService("TweenService")
local tsinfo = TweenInfo.new(0.2,Enum.EasingStyle.Sine)

local attachment = Instance.new("Attachment")
attachment.Parent = char:WaitForChild("Head")
attachment.Name = "NeckAttachment"

script.CameraPos.OnServerEvent:Connect(function(plr,cf)
	local sx, sy, sz, m00, m01, m02, m10, m11, m12, m20, m21, m22 = cf:GetComponents()

	local X = math.atan2(-m12, m22)

	local Y = math.asin(m02)

	local Z = math.atan2(-m01, m00)
	
	attachment.WorldCFrame = CFrame.Angles(X,Y,Z)
	
	local rotationcframe = attachment.CFrame.Rotation
	
	local fullcframe = rotationcframe + neck.C0.Position
		
	ts:Create(neck,tsinfo,{C0 = fullcframe}):Play()
end)

I probably would’ve done this now that I thought of it (this might or might not work, i cant test it in studio right now)

script.CameraPos.OnServerEvent:Connect(function(plr, cf)
    local char = script.Parent
    local neck = char:WaitForChild("Head").Neck
    local ts = game:GetService("TweenService")
    local tsinfo = TweenInfo.new(0.2, Enum.EasingStyle.Sine)

    -- Get the character's torso (or root part) orientation
    local root = char:WaitForChild("HumanoidRootPart")
    local rootCFrame = root.CFrame
    local relativeCFrame = rootCFrame:ToObjectSpace(cf)

    -- Decompose the relative CFrame to angles
    local sx, sy, sz, m00, m01, m02, m10, m11, m12, m20, m21, m22 = relativeCFrame:GetComponents()
    local X = math.atan2(-m12, m22)
    local Y = math.asin(m02)
    local Z = math.atan2(-m01, m00)

    local targetC0 = CFrame.Angles(X, Y, Z) + neck.C0.Position
    ts:Create(neck, tsinfo, {C0 = targetC0}):Play()
end)

but after all, this is just an improvement to this

or at least just a change
