So I am trying to make a multi-floor bouncing slime block elevator.
It's totally out of my league, but I tried anyway. And completely failed.
My idea was that I would have an classic bouncing elevator, but the levels of the elevator would always be extended instead of the normal way, which is retracted. This is to make the mechanism that brought you to the lower floor easier. All you had to do was press a button to retract the slime block you were standing on, and you would drop to the lower floor. That means that to go up, when you pressed a button, the level above you would retract, the slime block below you popped you up, then the level that was above you would extend again.
I needz halpz!!!
P.S. I eventually want to implement this in an SMP world, so please give help that is feasible in survival! Thanks!
Here are some diagrams of what I envision (thanks, microsoft paint!):
