Custom Camera Script Stuttering Bug

Help and Feedback Scripting Support

So i have this one camera script i ripped from the asset manager and am trying to implement a 3rd person 1st person support for it. It’s working, but i can’t seem to fix the stuttering issue.

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local human = character:WaitForChild("Humanoid")
local humanoidpart = character:WaitForChild("HumanoidRootPart")
local head = character:WaitForChild("Head")

local input = game:GetService("UserInputService")
local runService = game:GetService("RunService")

-- Settings
local Sensitivity = 0.6
local Smoothness = 0.05	
local HeadOffset = CFrame.new(0, 0.7, 0)

-- State
local CamPos, TargetCamPos = cam.CFrame.Position, cam.CFrame.Position 
local AngleX, TargetAngleX = 0, 0
local AngleY, TargetAngleY = 0, 0
local CanViewBody = true
local firstPersonEnabled = false

local function lerp(a, b, t)
	return a * (1 - t) + (b * t)
end

local function updateCharTransparency()
	for _, v in pairs(character:GetChildren()) do
		if v:IsA("BasePart") or v:IsA("UnionOperation") or v:IsA("MeshPart") then
			v.LocalTransparencyModifier = 1
			v.CanCollide = false
		elseif v:IsA("Accessory") or v:IsA("Hat") then
			if v:FindFirstChild("Handle") then
				v.Handle.LocalTransparencyModifier = 1
				v.Handle.CanCollide = false
			end
		end
	end
end

-- Run every frame
runService.RenderStepped:Connect(function()
	local camToHead = (cam.CFrame.Position - head.Position).Magnitude
	local isFirstPerson = cam.CameraType == Enum.CameraType.Custom and camToHead < 1

	if isFirstPerson then
		if not firstPersonEnabled then
			firstPersonEnabled = true
			updateCharTransparency()
		end

		CamPos = CamPos + (TargetCamPos - CamPos) * 0.28 
		AngleX = AngleX + (TargetAngleX - AngleX) * 0.35 
		local dist = TargetAngleY - AngleY 
		dist = math.abs(dist) > 180 and dist - (dist / math.abs(dist)) * 360 or dist 
		AngleY = (AngleY + dist * 0.35) % 360

		cam.CFrame = CFrame.new(head.Position)
			* CFrame.Angles(0, math.rad(AngleY), 0)
			* CFrame.Angles(math.rad(AngleX), 0, 0)
			* HeadOffset

		humanoidpart.CFrame = CFrame.new(humanoidpart.Position) * CFrame.Angles(0, math.rad(AngleY), 0)
	else
		firstPersonEnabled = false
	end
end)

input.InputChanged:Connect(function(inputObject)
	if not firstPersonEnabled then return end

	if inputObject.UserInputType == Enum.UserInputType.MouseMovement then
		local delta = Vector2.new(inputObject.Delta.x / Sensitivity, inputObject.Delta.y / Sensitivity) * Smoothness
		local X = TargetAngleX - delta.y 
		TargetAngleX = math.clamp(X, -80, 80)
		TargetAngleY = (TargetAngleY - delta.x) % 360 
	end	
end)

Any support is appreciated. I’m still trash when it comes to scripting.

no need of function lerp
math.lerp already exists.
Also you most likely want to apply positions first there so
CFrame.new(head.Position)*HeadOffset and only then apply rotation

3

instead of RenderStepped, try one of these:
PreRender, PreAnimation, PreSimulation, PostSimulation

4

Add Heartbeat to the list.
