Problem with camera bobble

Help and Feedback Scripting Support
1

I want to make a bobble system for my first person horror game but I encountered an issue

When I walk, my body parts in my pov are shaking so much, but I don’t want them to shake, is there a solution to my problem ?

I tried manipulating the positions and more but couldn’t fix this problem

Also i use a script to show my body parts at first person

Here’s the script i use for the first camera and bobble

local LocalPlayer = game.Players.LocalPlayer
local Character = LocalPlayer.Character or LocalPlayer.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")
local Camera = workspace.CurrentCamera

local RunService  = game:GetService("RunService")
local UIS = game:GetService("UserInputService")


local TimeMoving = 0

local Intensity = 0.5
local NormalSpeed = 16
local Distance = 1.3
local frequence = 1


local chosenLerpRateX
local chosenLerpRateY

--Bobble Parameters
local lerpPowerX = 0.25
local lerpPowerY = 0.40
local StartTreshold = 2

local TimeMoving = 0
local CurrentTime

--Reset camera function
local FirstPersonVector = Vector3.new(0, 0,-1.8)



local function SetCameraToFirstPerson(setting)
	local speed = 0.1
	if setting == "smooth" then
		Humanoid.CameraOffset = Humanoid.CameraOffset:lerp(FirstPersonVector, speed)
	else
		Humanoid.CameraOffset = FirstPersonVector
	end
end

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


--Main loop
RunService.RenderStepped:Connect(function(step)
	
	--FirstPerson (show body and zoom a little bit)
	--Humanoid.CameraOffset = Vector3.new(0,0,-1)
	for i, part in ipairs(Character:GetChildren()) do
		if part.ClassName == "MeshPart" and part.Name ~= "Head" then
			part.LocalTransparencyModifier = 0
		end
	end
	

	
	
	

	
	--bobble thing :
	
	
	
	if Humanoid.MoveDirection.Magnitude > 0 then
		if CurrentTime == nil then return end
		
		local Speed = Humanoid.RootPart.Velocity.Magnitude
		
		local T = tick()
		
		local DeltaTime = tick() - CurrentTime
		
		TimeMoving = TimeMoving + DeltaTime
		

		

		
		

		if TimeMoving < StartTreshold then
			local StartWalkingLerp = 0.25 * TimeMoving
			chosenLerpRateX = StartWalkingLerp
			chosenLerpRateY = StartWalkingLerp
		else
			chosenLerpRateX = lerpPowerX
			chosenLerpRateY = lerpPowerY
		end
		
		--print(chosenLerpRate)
		
		-- Is the character walking?

		
		local bobble_X = 0.3 * 0.5 * math.cos(2 * math.pi * frequence * T) * math.min(1, Speed / NormalSpeed)
		local bobble_Y = 0.5 * 0.7 * math.abs(math.sin(2 * math.pi * frequence * T)) * math.min(1, Speed / NormalSpeed)
		
		--print("Before : ",bobble_Y)
		--print("After : ",bobble_Y)
		
		
		
		--print("before : ",Humanoid.CameraOffset)
		--local bobble = Vector3.new(bobble_X, bobble_Y, FirstPersonVector.Z)-- * math.min(1, velocity.Magnitude / Humanoid.WalkSpeed)
		
		local currentOffset = Humanoid.CameraOffset
		
		--bobble_X = lerp(currentOffset.X, bobble_X, chosenLerpRateX)
		bobble_Y = lerp(currentOffset.Y, bobble_Y, chosenLerpRateY)

		Humanoid.CameraOffset = Vector3.new(0, bobble_Y, FirstPersonVector.Z) --Replace with Tweens cuz it's bad
		
		
	else
		-- Scale down the CameraOffset so that it shifts back to its regular position.
		TimeMoving = 0
		
		SetCameraToFirstPerson("smooth")
	end
	CurrentTime = tick()
end)

I believe it is just because the default roblox walk has a bobbly look, you will have to make your own walking animation.

Oh i see, if i create a rig which is the subject of the camera, will it fix the problem (like in aresenal for exemple) ?

I think arsenal uses viewport frames to show the player’s hands, so the animations aren’t visible in first person.
