Elevators allow you to move between floors easily (through teleportation). Signs must be created in the same location but above or below in order to link floors to each other.
Elevators are just wall signs that are above or below each other. However, there are three different types of wall signs that determine what you can do on a certain level.
- Using [Lift Up] on the second line of a sign allows players to right click the sign to go upwards toward any other elevator sign.
- Using [Lift Down] on the second line of on a sign allows players to right click the sign to go downwards toward any other elevator sign.
- Using [Lift] on the second line of a sign prevents anyone from right clicking the sign, but you can use it tandem with the other two signs types.
The first line of a sign can be used to tell players who arrive at a level the name of the level.
If the elevator looping setting is enabled, if lift up is used and no elevators are above it, it will search from the bottom of the world up. The same goes for down lifts.

Elevators, as of version 2.0, will no longer put players in blocks and suffocate them if a teleportation would put a player in such a position. Elevators will also now check to see if there is flooring below the player at the destination. Be aware that elevators teleport the player directly upwards or downwards. Also when constructing an elevator, be sure to have 3 blocks of room height-wise or else you'll get the message "Your destination is obstructed."
You can't have one elevator system for multiple floors. An elevator goes always from the sign to the sign above or below it (defined by the sign text). If you want a multiple-floor elevator you simply need multiple elevators.
