I'm trying to recreate the hidden tunnel entrance that was shown in the 1.7 pistons vid where he flicks a switch and 2 stairs on top of each other come out from the wall to make a normal staircase.

I'm wanting to do it in a grander scale, like 3+ stairs on top of each other.
I can make them come out by putting a delay on the line that leads to where the next sticky piston is going to be for the bottom staircase, but because of the way I have it set up, it doesn't go back into the wall since the second piston is still extended while the first one retracts.
Any help is much appreciated.
I'm using Pistons mod which adds the sticky pistons.
Just make an opposite pyramid of sticky pistons.
I.E. if you want
It should look like this
The thing is a piston can't push a piston that is extending/extended so it's not as simple as it seems. I've managed to get just 2 stairs working, and now I'm trying 4 but it's a whole new ball game.
With just 2 pistons on the bottom it's easy to time everything, but with 4 the timing gets spread further and further apart since I have to account for the time it takes to extend/retract for each piston so that they all get pulled by the piston behind it and since there is 4, I someone gotta get the first to extend so that the redstone is lined up with the second instead of the third.
I don't think this is even possible. If I make the redstone get to the first piston before the others, the first piston won't pull the second piston when turning the switch off since the second piston will still be extended by the time the first pistons redstone dissipates.
EDIT: I'm trying now with 2 coming out from the wall and 2 coming up from the floor. Problem is I don't know how I got just the 2 to work since every time I try, the second piston when extending eats the stairs instead of pushing the stairs up/sideways another block.
If you look closely, you will see that the lower stairs in the video only actually extend 1 block, while the upper stairs remain motionless.
It goes from:
to
However, the question of getting sequential pistons to extend/retract in the right order is indeed a challenge. For two pistons, what you should do is make sure that the furthest piston always receives its signal first.
But won't that stop it from being pushed-out in the first place? Not if you make sure that the further-piston gets its signals from the spot it gets pushed TO. This way it stays contracted until it gets shifted into position, at which point it extends immediately.
What if you're trying to do 3 pistons in a chain? God help you.

That's how I have it set up, unfortunately the further-piston ends up eating the staircase instead of pushing it. I have no idea how I managed to get it to actually push the stairs the first time I tried.

Yeah I see that now. :sad.gif:
