Well here is another useless idea what about timeing the use key presses like 4 quick hits of the use key while at the selection panel will select the 4th floor and you have another use trigger to actually start the elevator moveing .
or 2 switches .one that moves a small light 2 the floor number u want (and behind the scenes changes the script 2 the selected floor) and the other actually moves the elevator 2 that floor (follows the selected script)
hope that makes sense
Just a thought but what about useing the train switch to move the elevator after selecting the floor like the old style elevators or make your own switch and have the elevator keep moveing as long as you hold the switch .
I think you can scale the train switch but the animation I think will make it move back to where it started after a few seconds I think , maybe not there maybe a animation to do that can't remember right now .
