SethBling – MapLock: Secure Multiplayer Lock with Copyable Keys — Minecraft Tutorial

Welcome back sethbling here today I’ve got something really cool for you guys it’s a lock system designed for multiplayer specifically is designed for servers that allow you to place protection over your base or house or whatever so that other people can’t break blocks and the lock system uses

Maps as the keys so the maps are completely secure as keys and if you want to share them with your friends so your friends have keys to your house then you can just clone the map let me show you what I’m talking about so here’s the depository where you put in

The item the map item in order to get in and over here the door will open and you can go right through now I just drop my map item in if I want to recover that I just come down here and I can go right up here to collect it now you’ll

Notice I’m holding two map items now that’s because one of them came from the dispenser here and this is what verifies that you gave it the correct the correct map as the key so if I come back up here and here this is the this is the map

That I use as the key here’s a very slightly different map you’ll notice there’s a little bit less explored territory in the top left it’s a slightly different map but it counts as a completely different map so if I toss this in I’ll first first need to lock

This up that’s all you have to do to lock you just press the button and it’ll stay locked so I’m going to use this this other map that isn’t a key that isn’t the correct key for this block toss it in and nothing happens doesn’t open the door and and the cool thing

About this is here’s the map that wasn’t the key and then in there is the map that was the key template that was used to verify the the the key was correct so this actually locks you out for five minutes from making more attempts so people can’t just sit here and keep

Dropping in items in order to exhaust the supply of maps in your dispenser because you can drop all the items you want after the first one and and no more maps are gonna get dispensed so here grab the atoms again and so let me let

Me toss in the actual key get into my base here now they’re there again the really cool thing about this is if you want to share share the key with your friends you can make a copy this way by just using an empty map and now you have

Two copies of the map you can just give one to your friends and they’ll be able to get in to and they can get go down here to recover it if they want and to restock the restock the dispenser with with the the key pretty cool system it’s

Very secure I think I mean only the map that that you want is the key is actually gonna be able to get you in the base so and and the fact that you can share the key with your friends is also really cool so it doesn’t rely on any

Combo locks or anything there’s actually no way to like guess your way in like most locks that I’ve seen I think every lock could I’ve seen you have to have the actual physical item that lets you in now here’s the system kind of with everything ripped out I’m not going to

Do a block by block tutorial on how it works but if you’re interested in checking out block by block there is a download link in the video description that you can download this this part here the stripped bare bones one and the complete system over there and you can

Download it and check it out block for block but I will go over the concepts that I used to create it so here’s the dispenser that has the kind of template maps in here I just stocked it up with a ton by using creative mode but you would have to

Stock it up using the cloning thing that I just talked about and so here’s the dispenser there is a slab here which is just something I discovered that makes the dispenser dispense the map in a much more reliable way it keeps it closer to the ground so this lab is necessary for

The for the machine and so you come up here and this is where you’ll toss in the key now the key is gonna fall past this pressure plate which triggers some redstone that that triggers the dispenser so anytime you throw in an item it’s going to trigger that dispenser so

If I throw in the correct map here we can see it triggers the dispenser and I don’t know if you saw it but the dispenser dispensed the item and it’s stacked with this map it’s because of the kind of new well it’s I guess it was 1.3 that the item stacking mechanism

That makes item stack if they have the same data although it didn’t work with mash before now it does and that’s what allows this lock to work when it wasn’t possible to work before I see it so you have the two Maps here in the stack and

Put one back dispenser now if I put something else in like the other map that this is the one remember that though isn’t the actual key if I drop it in they’re not going to stack up this is the fake key that isn’t the actual key

And then this is the template that is matching against now the Spencer because it’s dispensing on ice just had the item slide over to this pressure plate and that sort of suppressed the unlocking mechanism and let me let me show you how that works so when you drop the item

Through here it triggers the pressure plate which like I showed you before triggers the dispenser down here but it also triggers this little side circuit here and what this will do is it will turn off this torch which after eight ticks will allow this torch to turn on

And pulse this piston but when you put in an item into here that isn’t the key this this redstone line gets powered here which sort of suppresses the unlocking mechanism and so if I come over here and do that you can see that the template map over here is what

Suppressed the locking system and yeah there’s a lot to this that is actually pretty specific like you need glass surrounding this fence so you can try building it for yourself but if it doesn’t work then just come back to this and figure out what the differences are

Because there is a lot about this that you like you also need a pretty good drop from here for this tube that where the item drops down but it is quite reliable and I haven’t I haven’t had it failed on long for me yet so very cool system kind

Of the first of its kind where you can have a complete completely secure lock that will only open if you give it a completely unique item and I mean in or it’s very easy to generate new maps all you have to do is right-click with a an

Empty map so anytime you want a new lock you can just generate a new map and in fact if you have a map that you carry around with you all the time because it has the surroundings of your base it’s really easy to just you know carry that

Around you with you because you were carrying around carrying it around with you anyway then you can also use it as the as the lock for your base again this will only work if you’re in a server with protections so that other players can’t break your box they’re wise of

Course they could just mine right in but that’s kind of the caveat that all walking systems have I just have another button here that uh that pulses to Pistons to lock the door back up these are the two Pistons that pulse when you when they when the lock is activated our

Unlock I guess very cool system that I recommend you downloaded and take a look it’s it’s really cool that we’re able to do this now it’s pretty new pretty new mechanism that we weren’t able to access until one of the 1.4 releases I believe because items the map items didn’t use

The stack but if I can get it yeah couple of them stack there so hope you enjoyed and thanks for watching
