I suppose that you're using a code similar to the part : "DEMO : TEST CAMERA MOVES" to assign keys to camera commands.
In that case, you should replace :

Code:

elsif Input.press?(Input::L)
        increase_theta(2)
      elsif Input.press?(Input::R)
        increase_theta(-2)

by :

Code:

elsif Input.press?(Input::L) && $game_switches[your_switch_id]
        increase_theta(2)
      elsif Input.press?(Input::R) && $game_switches[your_switch_id]
        increase_theta(-2)

With this modification, if the switch which number is your_switch_id is active, so is the camera rotation.
