How do you make a FirstPerson Script?

You can do this to lock the player`s camera on first person when they enter the game:

game.Players.PlayerAdded:connect(function(plr) --Gets the player as they enter the game
    plr.CameraMode = Enum.CameraMode.LockFirstPerson --Changes the player`s cameramode property to lockfirstperson
end)

The above srcipt MUST be in a local script to work.

Put this in a LocalScript in StarterPack

while true do
    game.Players.LocalPlayer.CameraMaxZoomDistance = 0
    wait(15) -- So the game doesn't crash.
end
