yep i been waitthing for this for MOUNTHS 
Mouth months?
Well, I put the finishing touches on the generic explosion I'll be using for vehicles crushed by the Elevator, but I still have a good amount of work to do.
1. I need to make it so the players and vehicles are only crushed if they're pinned. If they're floating, they should get knocked down a bit.
2. I'll be making it so that vehicles can't ride in Elevators. Elevators inside the Elevator compartment will explode (just like getting crushed).
3. I have a small issue with brick detection to fix involving bricks in the detection area both above and below the Elevator platform.
4. Make it easier (read: less time-consuming) to make Elevator Doors for Elevators with more floors.
5. Make it so Elevator Doors can only be built within a certain distance of the Elevator platform.
6. Come up with a good way to call an Elevator to a floor when an Elevator Door is not present on that floor.
7. Then I have all the cool stuff to do.
A. Allowing floors to have names.
B. Allowing floors to be different heights in the same Elevator.
C. Create GUIs for selection up / down travel direction (after walking up to an Elevator).
D. Create logic that handles Elevator floor requests.
E. Add ability to save and load Elevators / Elevator Doors.
8. Testing, testing, and more testing.
That's all I can think of at the moment, but it seems to be a fairly good list.
