Elevators simply go up and down. They are very easy to construct.
Create your elevator between two rooms. Adjust the height of the two rooms so that one will be the top floor and the other will be the bottom floor. Texture the elevator (make sure you get every part of it, some parts won't be visible until you are using the elevator in the game). Place an M[StopSound,StartSound] (Speed[0,Speed]) within the elevator. I recommend M[73,71]. From here, there are four variations you can set up.
Elevator Platform Down
The elevator's platform will move from its current height down to the next floor.
Tag the elevator [0,16]. Raise the ceiling and floor of the elevator so they match the height of the top floor's ceiling and floor.
Elevator Platform Up
The elevator's platform will move from its current height up to the next floor.
Tag the elevator [0,17]. Raise the elevator's ceiling so it matches the height of the top floor's ceiling. Lower the elevator's floor so it matches the height of the bottom floor's floor.
Elevator Down
The elevator's floor and ceiling will move from their current height down to the next floor.
Tag the elevator [0,18]. Raise the elevator's floor and ceiling so they match the height of the top floor's floor and ceiling.
Elevator Up
The elevator's floor and ceiling will move from their current height up to the next floor.
Tag the elevator [0,19]. Lower the elevator's floor and ceiling so they match the height of the bottom floor's floor and ceiling.
Notes:
- Technically, the Elevator Up/Down tags are interchangeable, and the Elevator Platform Up/Down tags are interchangeable.
- If a player begins a map touching an elevator sector floor (including the initial floor of a transport elevator), the elevator will be automatically triggered (as in
E1L2.MAP: "Red Light District", andE2L3.MAP: "Warp Factor").
