First person zoom-in lock?[NOT SOLVED]

for my horror game I want the player to be stuck in first person, and they can't zoom out.

Here is a ROBLOX wiki link. Since you did not post what you tried

put this in a local script

game:GetService('Players').LocalPlayer.CameraMode = Enum.CameraMode.LockFirstPerson

This is NOT a request site many of your questions are answered in the Roblox Wiki.
