Insane Minecraft Secret Door-Lock with Hoppers!

What’s up everybody my name is Ken welcome back to another minecraft tutorial today I’m going to show you something that you may have seen I’ve seen a few other people do some examples of this before but I’ve never seen one that I’ve never seen that actually has it completely hidden so let’s say

Hypothetically you’re designing an adventure map or a puzzle map or anything and you want to prevent somebody from getting to an area until they have the specific key in this example I’m going to use it’s a key one so you’re doing a RPG style thing said

You find key one open up here and place key one so you think okay I’ll just randomly pleaseplease the dirt in there see what happens nope door doesn’t open okay so this would keep them from being able to find until they got this specific key that you wanted and key one

Put it in there da da da they come through door opens like I said you may have seen this example shown up in other places before of how to do a lock like this where it requires a certain thing but if you’ll notice everything is completely hidden here – the dispenser

Where you put the actual key in here so I wanted to show you guys how to do that it’s really not that complicated but it’s something I found quite interesting so I want to show you guys how to do that already then welcome back here I went ahead and exposed all of the

Secrets behind how this actually works as you can see it’s not really that complicated but I’ll walk you through it anyway for starters and if I wanted to know all I did was to get this say place key one that just got a dispenser put it

Inside the anvil but you have to use experience points to do so I mean let’s get a creative mode of course and then rename it whatever you want to these right here these are just trip wires they kind of look like keys so a lot of

People use them is their same thing just put one of them in here name it whatever you want to take it out and that’s the item of this so if you want to have some a key named key 1 or key 2 or dungeon key or whatever that’s all there and

Then just assign iron doors so they can’t get through now let’s go look around on the other side so what you’re going to need for this is a dispenser I’m using two hoppers and the reason I’m using two is because it makes it lower into the ground if you use just one that

Means everything else is going to be just one block below it and you start putting dirt on top of it and it starts cutting off signals things don’t start working the way they want to and so it’s if you want it to be completely hidden so there’s no

Can’t see behind the scenes the wires and which makes it work use to hoppers just place one on top of each the other now here’s something you have to do when you’re using hoppers if you want them to go into each other you have to hold control when you actually click to get

It to go on there if you just put this down here if you just wanna put this right here you just throw it like this into that spot you’re going to see it connects itself into this little block here so what you got to do is hold

Control click and now you see that the funnel goes all the way down inside here and since it’s attached to this it will go automatically down now this is what’s called it’s called a redstone comparator now it works kid it looks kind of similar to the redstone repeater it’s

Got the two little torches here that you it looks like you can adjust but it’s got the one torch out here that if you’re right clicking see turns on and off okay now these things are a little bit complicated I’m not going to go into exactly how they work here in this

Particular tutorial if you guys want to see me do a tutorial on how to actually get them to work then I’ll do that there’s a lot of to them there but just so you know here the spot coming in the back of it that’s the first input here

That’s where that’s input a the sides coming out this way coming out this way whichever one you’re using is considered input B and that’s output so basically it looks at how much power is coming into one of the sides and then it won’t release the power out here out the front

Onto the output and less the amount of power going in this side is more than that I know that sounds complicated I don’t know you’re thinking the same thing that I did when I first looked into it like what are you talking about so redstone torch puts off 15 as far as

Like spaces the number of redstone will go it goes for 15 spaces so we call it a power 15 so the redstone goes 15 in so right now there’s 15 going in here well without having to go into a whole lot of the actual math behind it a hopper has

Five different spaces here in order to get more than 15 or 15 or more power you have to have all the slots filled so that’s basically how you have this here this hopper you can leave completely empty and this one down here what you want to do the to save space and just

Use non stacking items I use wooden doors too easy to make they don’t stack you can use if you want to put 64 of an item in each one of these you can wooden doors just the easiest that I always go with because they don’t stack

And then over here what you want to do in this spot is put 63 of whatever it is that you want to make here so yes this requires some creative you know workings and stuff here to make that many items but the easiest way to do this is once

You have one if you got a wheel mouse on your mouse just click the wheel mouse and boom you got 64 more put it in there now you need 63 because when you get to 64 you heard the door open see it opened up there because now this is putting out

As much power or more than that one so it lights it up here now let me get this back out of here so it closes it okay so that’s the basics there just hook it up this way now make sure this torch is off because when it’s on like that then it

Does it’s a subtraction and it’s a whole lot of different math here so make sure it’s off from here I have redstone going out comes out comes around here into a not gate or an inverter basically so it means while this is off the other side

Is on this is basic redstone comes into another not gate or another inverter you got two one here that way when this one’s off this one’s off and when this one’s on say we go ahead and we put our magic key in there doors open you see

Now this one’s on it turns this switch off and it comes over here and it turns this one on now having this this torch underneath where the doors actually at will help it activate it there if you run just plain redstone under here it doesn’t go through blocks like torches

Do so you won’t get the actual power you need and then all you have to do is just cover it up with dirt and or you know whatever your material is if you want to cover it up with something decorative you’re doing for your particular world

That’s all you have to do now the only thing that’s kind of a challenge was doing it this way is that once the door is open it’s open I mean there’s nothing in here so it’s not like they can take it out to close it again so this is kind

Of one of those one way only sort of things once you’re in here that door is open you can’t get it back so if you ever needed to reset it what you’d have to do is go back into this bottom sorry bottom hopper take out one item

And you’re good to go and cover back up and now it’s closed and then it’s ready to go for however you want to do this put your one key in there tada and that’s how you do it if you have any questions like I said if

You want me to go into an in-depth about how the comparator actually works because it’s it’s kind of a complicated little beast you know I’d be more than happy to make one of those if you have any questions like I said don’t hesitate to ask not

Trying to help out Oh a good question here is you can use stuff like a chest or you could actually just make it so that there’s one hopper right here and make them so they put the item in there I like the dispenser because it’s got a

Smiley face on the front of it well mainly just because it’s got the same number of inventory spaces docket crafting table does but you can have a block on top of it if you put a chest there and stick a block on top of it like this you can’t open it because the

Lid can’t open till well let you click it so as far as adventure things go a dispenser works really good a dropper also works so it’s just kind of one of those whatever you want to use they’re actually work setting is kind of experiment so you have any questions

Leave them in the comments below you guys have a good one and I will talk to you later
