First Person Camera Movement Sway and Idle Sway

Resources Community Resources
#1

By creating a local script in StarterPlayerScripts, you can now have camera sway when you move your mouse, you will also have camera sway when you are not moving to apply a breathing effect.

Create a local script and paste it in StarterPlayerScripts. Hopefully this helps developers out.

--Services
local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")

--constants
local PLAYER = Players.LocalPlayer
local CAMERA = workspace.CurrentCamera
local SX,SY = .05,.04 -- IDLE sway speed
local MXY = 0.0005 --center position
local SIN,PI_2 = math.sin,math.pi*2
local IDLE_LERP_SPEED = .01

--varibables 
local ix,iy = 0,0
local lsx,lsy = SX,SY
local lx,ly = MXY,MXY

--variables
local turn = 0

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

PLAYER.CameraMode = Enum.CameraMode.LockFirstPerson

RunService:BindToRenderStep("CameraSway", Enum.RenderPriority.Camera.Value + 1, function(deltaTime)
	local MouseDelta = UserInputService:GetMouseDelta()
	turn = lerp(turn, math.clamp(MouseDelta.X, -3, 3), (15 * deltaTime))
	
	lsx=lerp(lsx,SX,IDLE_LERP_SPEED)
	lx=lerp(lx,MXY,IDLE_LERP_SPEED)
	lsy=lerp(lsy,SY,IDLE_LERP_SPEED)
	ly=lerp(ly,MXY,IDLE_LERP_SPEED)
	
	ix = (ix + lsx)%PI_2
	iy = (iy + lsy)%PI_2

	CAMERA.CFrame = CAMERA.CFrame * CFrame.Angles(0, 0, math.rad(turn)) * 
        CFrame.Angles(SIN(ix)*lx,SIN(iy)*ly,0)
end)

How to make camera moves a bit when standing
#2

Updated Version, which also pauses a second before idle sway so the two sways are not interfering which each other.

--Services
local RunService = game:GetService("RunService")
local UserInputService = game:GetService("UserInputService")
local Players = game:GetService("Players")

--constants
local PLAYER = Players.LocalPlayer
local CAMERA = workspace.CurrentCamera
local SX,SY = .05,.04 -- IDLE sway speed
local MXY = 0.0005 --center position
local SIN,PI_2 = math.sin,math.pi*2
local IDLE_LERP_SPEED = .01

--varibables 
local ix,iy = 0,0
local lsx,lsy = SX,SY
local lx,ly = MXY,MXY

--variables
local turn = 0
local lastCFramePosition = nil
local lastMoveTick = tick()

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

PLAYER.CameraMode = Enum.CameraMode.LockFirstPerson

RunService:BindToRenderStep("CameraSway", Enum.RenderPriority.Camera.Value + 1, function(deltaTime)
	local MouseDelta = UserInputService:GetMouseDelta()
	turn = lerp(turn, math.clamp(MouseDelta.X, -3, 3), (15 * deltaTime))
	
	lsx=lerp(lsx,SX,IDLE_LERP_SPEED)
	lx=lerp(lx,MXY,IDLE_LERP_SPEED)
	lsy=lerp(lsy,SY,IDLE_LERP_SPEED)
	ly=lerp(ly,MXY,IDLE_LERP_SPEED)
	
	ix = (ix + lsx)%PI_2
	iy = (iy + lsy)%PI_2
	
	CAMERA.CFrame = CAMERA.CFrame * CFrame.Angles(0, 0, math.rad(turn))
	
	if lastCFramePosition and (lastCFramePosition - CAMERA.CFrame.Position).magnitude > .01 then lastMoveTick = tick() end
	
	if tick() - lastMoveTick > 1 then CAMERA.CFrame = CAMERA.CFrame * CFrame.Angles(SIN(ix)*lx,SIN(iy)*ly,0) end
	
	lastCFramePosition = CAMERA.CFrame.Position
end)

Its really nice ngl, love it the camera swaying! - will be a good edition to horror games!

could you add some videos or gifs of the effect in action? It’d help to know in advance what it looks like and what it does

Otherwise, a neat effect

Here is the code in action!

This is a great resource, thank you!

If you wouldn’t mind, however; could you provide a small explanation of each part of the code as it may be confusing for some to understand!
