making use of the down time

Post  Mimodo on Mon Feb 20, 2012 10:38 am

So, i decided to do something with the spare time.

I have designed (almost) a redstone combination button lock. We can use this for the "secret vault" suggestion, using the buttons on the pillars in the lower entrance hallway. It is order sensitive, and resets if the wrong button is pressed...

I also came up with my own design of a 2*2 piston door, which we can use for the shortcut access to the old zombie grinder/dome

Ok, i now have a working, order sensitive button combination lock Very Happy You MUST press the buttons in the right order to gain entry... press one wrong button, and you need to reset and start again...

I'll definitely be awed when I see it in function and tried it myself. Smile

However long you want. I can even put a pressure plate so it only close once you walk through.

For the really special vaults put the pressure plates all around the room.

A cool thing you can do is put a simple XOR gate at the end of the circuit, with one input being the correct input from the combination lock, and the other from a leaver inside the vault, with the output being the door. This gives the vault a 'deadlock' (I think it's called). In effect it means once the door is opened from the outside, you must close it with the leaver from the inside, this will prevent anyone else from entering, even if they punch in the correct code, until it's unlocked from the inside. The one problem with that on a multiplayer server is obviously people logging off inside the vault, but I just thought I'd share Smile

It's an idea, but it Does require changing other things... But do we really need a feature like that??? Obviously those with the code are right to enter

we almost certainally don't need it, I use it on my server, but that's a server with actual hostiles trying to steal my diamonds, it's pretty unnecessary here, but I just thought I'd mention it Razz

Except that an XOR gate, as was demonstrated in the dome a few days ago...would still open if the correct output was provided, as it changes state whenever either of the two outputs changes state.

A better setup would be a circuit which, when provided power, seals the vault. Putting in the correct code turns off the redstone torch that otherwise would provide the power. But inside the vault is a switch on the same circuit, which when turned on, also provides power, but which can't be cut off by the lock mechanism olutside.

All this is not gonna actually keep anyone with a diamond pick out, of course, but that's the nature of minecraft.

can you explain that a bit differently please? I dont follow...

Also, i was thinking a piston door.

You walk through, and upon walking through, you stand on a pressure plate which shuts the door behind you. To get out, you need to press another button, which will open the door for a set amount of time

A redstone torch supplies power to sticky pistons, which thus extend and close the door.

If you input the right code, power is sent to the block that the torch is attached to, turning the torch off. Deprived of power, the pistons retract, and the door is opened.

Also connected to the line of redstone wire from the torch to the pistons is a switch. Leave the switch off, and the circuit behaves as described above. Turn the switch on, and it supplies power to the pistons, whether the torch is on or off. The pistons extend, the door is closed, and the vault is sealed.

So basically have a seal from the inside? to make sure it stays shut behind you?

Since that seemed to be the intent of the setup you described before, I suggested a simpler alternative way of wiring it up.

My intent wasn't to lock it, but just have it stay open until you enter. Once you enter it will close, until someone in the outside opens it, or you press the button inside to open the door
