# Inverting pressure plate without powering piston

• Inverting pressure plate without powering piston Jarwain

I'm working on a trap, where if a person steps on a pressure plate, then the pistons deactivate and a pit forms in front of the plate. I decided to do this like a vertical jeb's door (a piston door in a flat surface.)

The issue I am having is that the pressure plate is powering the upwards piston directly next to it. Is there a way to invert the charge from the presureplate without powering the piston? Preferably without moving the plate away from the pistons.

Side view 1 shows how I implemented the jeb's door. The issue is that the pressureplate that triggers the trap is also activating the [s^] piston directly next to the plate. I hope my diagrams are understandable, otherwise I can provide screenshots. :3

• [p] = pressureplate
• [d] = dirt
• [s] = stickypiston (>,<,^,v = Piston Direction extended)
• [r] = redstone
• [1-4] = repeater with 1-4 number of ticks
• [a] = air
• |[b]| = Section for Side view
• [t] = redstoneTorch

• You cannot invert a pressure plate, but you can move the piston away from the plate.

I don't quite understand your diagram, but from your description of what you're trying to do I've come up with a solution.

I hope you can see all the wiring in this picture, the other side is an exact mirror of this one, the repeaters are set to two ticks and all the pistons are sticky.

• I am not sure if I understood correctly, but you can use a sticky piston under the pressure plate to cut off a wire that powers the other three pistons:

And with the pressure plate 'on':

You can power the side pistons with repeaters, if you want the ground to be flat.

• on top of each other (A, B and C) with A on top. I have a redstone repeater aiming at a wood block that is next to A .RXA XXXB XXXC Where X is wood, . is wire and R is a redstone repeater. Starting from off, if I turn power on at A, only A goes out. If I then turn on power to C, B and C go out. If I remove power to C, only C retracts. Once I remove power to A, A and B retract. If I toggle power the other way: If I turn power on to C, then C goes out. If I turn power on to A, only A goes out, not B. If I remove power to C, then C goes in and B goes out. This is madness. If I remove

• I'm trying to make a variation on the sticky-piston hidden door, in which two sticky pistons are activated by a pressure plate in a corridor to reveal either a hidden room, or a treasure chest, or trap, or anything else. Stepping on the pressure plate would turn off the circuit so that one sticky piston pulls a block up into the ceiling, and the other pulls a block down into the floor. The resultant opening is one block wide by two blocks high. The problem is I don't know how to wire the redstone vertically. A basic sticky-piston door is easy, as long as the blocks slide left or right

• I'm looking at figuring out a complex (ish) hidden door and I'm going to be using a fair few pistons. A lot of the time I'm going to need to use pistons in different orders. Example (All sticky pistons) Opening Piston 1 pushes Piston 2 behind a block Piston 2 pushes out a block. Closing Piston 2 pulls the block Piston 1 pulls back Piston 2 There depending if I'm opening or closing the door I need to fire the pistons in a different order. Is there a "recommended" method of doing this in Minecraft?
