How can I make a script for making the player and camera not move at all?

I have tried

Player.Movement = false

and

lockCamera = true

To lock the camera, you can put a local script in StarterPlayerScripts under StarterPlayer and put:

local cameraHeight = 12
local cameraZOffset = 20
 
local camera = game.Workspace.CurrentCamera
local player = game.Players.LocalPlayer
 
local function setupCamera()
	camera.CFrame = CFrame.new(Vector3.new(0,cameraHeight,cameraZOffset), Vector3.new(0,cameraHeight,0))
end
setupCamera()
player.CharacterAdded:Connect(setupCamera)

To 'freeze' the player you can put the following local script in StarterCharacterScripts:

game.Players.LocalPlayer.Character.Humanoid.WalkSpeed = 0

Don't forget to accept the answer if I helped!
