I decided to try this. I have a 10-sided cylinder, within which is a pentagonal shaped room. There are two exits from the room, on two of the five sides. Now, what I would like it to do is when a button is pressed, the room to rotate 72 degrees and then stop, and then, when pressed again, rotate a further 72 degrees, and so on. The idea is to have five passages leading to a room, but only two of those passages have access to the room, while at the same time the remaining three are left with a blank wall. Is this possible?
