Custom First Person Camera

[MarshmellowMan1604]

I’m trying to make a camera that is exactly like roblox studio’s camera, I have gotten close to make it but the camera seemed wobbly and so I gave up and came to the dev forum for help.

please hepl

thanks…

This is not the category for this, you should show code if you save some or look somewhere else for help.

You can look through the Freecan script Roblox implemented at runtime. game.Players.Player.PlayerGui

Hello! I have already implemented something like the studio camera before from one of my old games before, Put it in StarterPlayerScript

I hope this helps!

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

local camera = workspace.CurrentCamera
local player = Players.LocalPlayer
local mouse = player:GetMouse()

local cameraPosition = CFrame.new() -- default camera position
local cameraMoveSpeed = 1 -- speed of the camera
local rotationSensitivity = 2.5 -- the sensitivity of the camera
local mouseDelta = Vector2.zero
local mouseHolding = false

repeat 
	camera.CameraType = Enum.CameraType.Scriptable
	task.wait(1)
until camera.CameraType == Enum.CameraType.Scriptable
camera.CFrame = CFrame.new() -- the camera rotations can be wonky 
cameraPosition = camera.CFrame

local function getMoveDirection()
	local moveDirection = Vector3.zero

	if UserInputService.KeyboardEnabled then
		if UserInputService:IsKeyDown(Enum.KeyCode.W) then
			moveDirection += camera.CFrame.LookVector
		end

		if UserInputService:IsKeyDown(Enum.KeyCode.S) then
			moveDirection += -camera.CFrame.LookVector
		end

		if UserInputService:IsKeyDown(Enum.KeyCode.A) then
			moveDirection += -camera.CFrame.RightVector
		end

		if UserInputService:IsKeyDown(Enum.KeyCode.D) then
			moveDirection += camera.CFrame.RightVector
		end
		
		if UserInputService:IsKeyDown(Enum.KeyCode.Q) then
			moveDirection += camera.CFrame.UpVector
		end
		
		if UserInputService:IsKeyDown(Enum.KeyCode.E) then
			moveDirection -= camera.CFrame.UpVector
		end
	end
	
	return moveDirection * cameraMoveSpeed
end

RunService.RenderStepped:Connect(function()
	local moveDirection = CFrame.new(getMoveDirection())
	local rotation = CFrame.Angles(0, math.rad(mouseDelta.X), 0) * CFrame.Angles(math.rad(mouseDelta.Y), 0, 0)

	cameraPosition = cameraPosition * moveDirection -- setting the camera position variable
	camera.CFrame = cameraPosition * rotation -- setting the position and rotation
end) 

UserInputService.InputChanged:Connect(function(Input)
	if Input.UserInputType == Enum.UserInputType.MouseMovement and mouseHolding then
		local inputDelta = Input.Delta
		
		 -- so we could rotate the camera

		mouseDelta = Vector3.new(
			mouseDelta.X - (inputDelta.X / rotationSensitivity),
			math.clamp(mouseDelta.Y - inputDelta.Y / rotationSensitivity, -80, 80)
		)
	end
end)

-- locking the mouse position like in studio

UserInputService.InputBegan:Connect(function(input, gameProcessed)
	if gameProcessed then return end

	if input.UserInputType == Enum.UserInputType.MouseButton2 then
		mouseHolding = true
		UserInputService.MouseBehavior = Enum.MouseBehavior.LockCurrentPosition
	end
end)

UserInputService.InputEnded:Connect(function(Input)
	if Input.UserInputType == Enum.UserInputType.MouseButton2 then
		mouseHolding = false
		UserInputService.MouseBehavior = Enum.MouseBehavior.Default
	end
end)
