Smooth first person camera

Help and Feedback Scripting Support
#1

Hello guys,
I can’t figure out how is smooth camera made in “DOORS” game (of course first person camera!!). What did they do to make it smooth. I tried Torsion Spring but it was not working. Do you know how was it done or do you have any scripts for that?

try this script put it in startergui

repeat wait() until game:GetService(“Players”).LocalPlayer.Character ~= nil
local runService = game:GetService(“RunService”)
local input = game:GetService(“UserInputService”)
local players = game:GetService(“Players”)

– you can mess with these settings
CanToggleMouse = {allowed = true; activationkey = Enum.KeyCode.V;} – lets you move your mouse around in firstperson
CanViewBody = true – whether you see your body
Sensitivity = 0.6 – anything higher would make looking up and down harder; recommend anything between 0~1
Smoothness = 0.05 – recommend anything between 0~1
FieldOfView = 80 – fov
HeadOffset = CFrame.new(0,0.7,0) – how far your camera is from your head

local cam = game.Workspace.CurrentCamera
local player = players.LocalPlayer
local m = player:GetMouse()
m.Icon = “http://www.roblox.com/asset/?id=7213486631” – replaces mouse icon
local character = player.Character or player.CharacterAdded:wait()
local human = character.Humanoid

I did my own, that doesn’t use keyboard or smth, based on a lot maths but your works too so I will check this one as solution

Can you send it to me? I’m also in need of something similiar, but I don’t like math.

Could you open source it on GitHub?

The problem with the solution is that when you walk backwards, your character sways a little bit towards the left or right and returns back to straight after you stop walking. This problem doesn’t happen with forward or sideward movements.

@ne3ulimity (tagged because you also wanted it)

i did a full tutorial on it for Polish community, but if you want you can scroll down and just copy whole code :smiley:
let me know if it works!
