Your elevator will only move up and down when a switch is pressed.
Create any type of elevator. Now place an A[0,Channel]
in the elevator sector. Then place a Switch[ActivationSound,Channel]
somewhere in the level. I recommend placing two Switches
in the level (one on the top floor and one on the bottom floor). Otherwise your elevator can only be used from one floor. Note: Not all switch sprites will work with this effect.
