Create an Elevator

RollupBar→Entity→Elevators

Here are a couple of settings i'll explain for the Elevator Entity: Elevator Entity Settings:

Automatic: This needs no switch. If you are going on your elevator platform, it will automatically move to the DestinationFloor, and it will go back in his InitialFloor position. But here, you are able to use switches too.
DestinationFloor: Number of your floors minus 1 The lowest floor is 0
FloorCount: Number of your floors
FloorHeight: height of the floors
InitialFloor: Example: Place your elevator platform at floor 2 and set the InitialFloor also to 2. So if you want to "drive" to floor 5, press the floor 5 switch (switch5 has setting: floor = 4), the elevator goes up 3x FloorHeight. So the elevator starts his journey from this floor you set in InitialFloor! (lowest floor = 0)
Axis: Specifies which axis the elevator moves in. For vertical elevators, set it to Z.
StopTime: Creates a cushion effect on the elevator. A higher value causes the elevator to stop slower and smoother.

Note

Everytime you change the position of the elevator, you need to press Reload Script of your elevator entity in the RollupBar

Now create some switches. For example for 3 floors, you need 3 switches. You'll see a yellow ball. You need to assign a model (Entity Properties).

Choose a switch, go to RollupBar, click Pick Target and click on your elevator platform. Rename the target link of each switch to "up" or "down".

For the entity properties of the switches set the floor property of the switch floor0 to 0, the floor property of floor1 switch to 1 ...etc

Set the entity properties of the elevator: DestinationFloor = 2

FloorCount = 3

FloorHeight = 3 (<- for example)

InitialFloor = 0 (if you want the platform to begin on the lowest floor)

Note

If you want that the switches moves simultaneously to the elevator, just hit the button Link Object and "drag" each switch to the elevator.
