Create the bottom floor with iron blocks. An elevator can be as small as 1 block or as big as 15 blocks in any shape. Smaller areas will have less lag.
Next create the floor's control panel. On a wall place the following blocks. The signs and buttons must be "over" one of the iron base blocks.
- Required sign, leave blank for now
- Button
- Optional sign with floor name on second line
- Iron floor block you just placed.
Create the elevator shaft. To create a new floor platform use glass blocks instead of iron. Like the first floor over one of the glass blocks create the floor interface.
- Required sign, leave blank for now
- Button
- Optional sign with floor name on second line
Make sure the shaft is clear of all obstructions except for floor glass, buttons and signs. Torches are also allowed in the elevator shaft.
To use your elevator right click the sign above the button to select a destination floor. The sign will automatically add the correct information.
