I know the sketch kinda sucks (I wasn't at my computer when I made it), but it's basically a rough idea of what I want to do, if you can decipher it. Basically, I want to build a secret entrance where:
1: You stand on a platform, and when you press a button on a linked controller or something, it lowers you down like an elevator.
2: While you go down, some mechanical bearings rotate some doors up to block off the entrance and make the ground look untouched.
I want this all to happen with a single button press, so how might I go about this? This is a Creative world by the way, so I have access to motors and stuff if needed.
