I'm trying to make a door that opens downwards from a wall (the glass represents where floor and walls will be, the mud are the blocks that need to move down).
So far i've managed to make the door open by sending a signal (white wool) that first moves down the first block and then moves it to the side, after that a delayed signal (green wool) makes a double piston extender pull the second block to be at floor height.
However i dont know how to make the door close after that, what i would need is for the double piston extender to trigger first and then the part that moves the first block; basically the inverse order of the opening.
Is there a way for the signal from the button to "know" when the door is open or closed in order for it to trigger the mechanisms in a different order?
thanks in advance! and sorry if my english is bad
