In Minecraft I need to make a piston door that opens when a plate is stepped on, it is normally the other way around. Does anyone know how? A video would be helpful but not required.
If you already have the door working (but inverted) just connect the pressure plate to the pistons using a NOT gate (a torch on a block) to invert the signal and therefore the door.
Simply put in a NOT Gate. A not gate is a redstone current running into a block which has a redstone torch attached to it (as shown in the first screenshot).
Here is a good example that uses a NOT gate.
This video really helped me out
pulses to the sticky pistons. I have set it up like this, and the circuit lights up when I step on the plate, and stays on constantly when I step off, until I break it by removing some redstone. What I think should be happening when I step on the plate is that the circuit should activate, sending current round the loop, each time round sending a pulse out to the sticky pistons (which I'm fairly sure are wired up correctly, as they do move when they receive current) - and that this should continue, even when I step off the plate. I've been fiddling around with this for 2 days, and just cannot
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
I've got a double door which I power from below, using a T-flip flop triggered by a pressure plate on the inside so that when I walk out, the doors open before me and when I walk in, the doors close... in this position, one opens before the other, and if I delay the first one with one click on the repeater, the behavior is switched. In this configuration (the delays are equal), the left door always opens and closes a half-step earlier. How can I get the doors perfectly in sync? Here's a screenshot:
So basically, I want to make a hidden Piston door using Redstone that opens and shuts when I pull a lever... underground, so that the door will close/open no matter what lever I use or in what state the other lever is. The basic order here is: When the door opens, M pulls the stone blocks back, after that L... with the others. The problem here is : How do I REVERSE the order of activation for the components L, R and M for when it closes and shuts? So Opening : M, L+R | Closing : L+R, M Or: Do you know
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
the redstone wire to wherever I need, and all of that in the underfloor area, so nothing of that is visible from outside. But since you can not, it seems that there is no other way than have a how just besides...I have this contraption with a floor plate that causes certain changes in a wall couple of blocks away (ie, firing pistons, etc). The floor plate is on a stone floor, and I wouldn't like to mess up the floor with redstone wire - all the wiring must be under the floor, and the floor must all be at one level. Well, I fail to understand this thing: how to get the signal down from the block on which
So, I've set up two traps near my base, hooked up to pressure plates.Inside each trap, I have some sticky pistons with blocks attached, such that when extended (turned on) no power reaches the various parts of my traps when the plate is triggered,rendering it deactivated. I have one of these for each trap, and it's basically some buttons with T-flip flops (to allow multiple buttons to have... current, so the trap is inactive. I have a second trap with the same setup. Is there a way for me to make a master switch that toggles both pistons or flip-flops on or off (together) even if one
I'm trying to make a hidden door in Minecraft. I have pressure plates set up to open the door, but since the door starts in open mode, when I use the pressure plates, it closes and then opens. How do I get it to start in closed position? What I have tried: I added a lever and that made it start in closed position but then my pressure plates would not work. What I want is the pressure plates to be the openers for the door so that you would have to run over the pressure plates to get through the door using the tiny window opportunity created by the plates.
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?
