Hey there, Im in need for a bit of advice. I want the player to get access to a certain -yet locked- door. To get it unlocked, he/she will have to activate 3 or more switches. Only if all 3 (or more) switches are activated, the door will unlock, possibly with an on-screen message and sound, since the locked door is not in the players sight. (The switches should also stay activated, so the player cant deactivate them again - to avoid confusion) If anyone knows how to do that, i'd be very happy! Thanks in advance.
