giant Minecraft machines are really quite simple that might sound absolutely ridiculous but I genuinely think learning how to build something like this is easier than learning how redstone contraptions were you see although this looks really big and really complicated and impressive it's a sort of thing you could show your mom and she'd be proud of you it's actually made up of just a handful of small simple circuits that once you learn you can basically build anything let's start with the three golden rules of big machines number one is get good at counting to 12 these machines are by the block push limit Piston's can only push 12 blocks at a time so you need to know when you've hit it 99% of the time the reason a build breaks is because you've gone past that limit without realizing always make a backup before testing anything and I also like to record my tests so that I can watch back the footage to see what has caused the breakage so I don't have to keep reloading the back up and testing it over and over again secret rule number four is embrace the frustration and pain okay let's begin with motors shall we so if you've only ever built one slime block flying machine machine before I would imagine it looks something like this we've got two sticky pistons facing in opposite directions and then we've got The Observers that are powering them and I thought it' be worth taking a look at actually why this thing works things do get complicated down the line we just have to start things off with the basics now I'm sure a decent number of you know that when you move and observe it it fires a short Redstone pulse of one Redstone tick and you can see that happening here now the cool thing about single Redstone tick pulses going into sticky pistons is it causes sticky pistons to actually spin out their block so in the example of this small flying machine here if we activate it you can see we have a loop going on our sticky piston is pushing this segment out which then causes an update through the Observer causing the sticky piston to fire bringing this segment along which then updates The Observer causing the sticky piston to fire for a redstone tick and we get this looping action happening if you understand this you understand how all giant Machines are made let's take a look at this slightly larger motor it uses exactly the same principles as that motor over there we just have one extra piston but the principle is the exact same when we fire this thing this first segment is going to be pushed across by one block then this sticky piston is going to grab this segment here and pull it along one block and then this sticky piston is going to pull this segment Along by a block and then the whole Loop is going to start all over again as you can see it is slightly slower than the flying machine that we originally looked at because there are more stages to the loop that's an important detail to remember but the system is the same this is how all giant machines work you're essentially creating a loop of pushes and pulls and then attaching things onto it now so far all of our motors have made use of observers to power the Pistons but you can also use redstone blocks on the pushing side of the sequence now this is obviously a very large loop with a very large number of steps this is going to be an incredibly slow flying machine but you can see the idea is the same we are creating a loop that just Cycles around gradually pushing and pulling our flying machine along these Pistons push the segments along which causes the Pistons to be powered pushing the next segment along until it gets the end and then we get to the pulling side of the loop and they all pull each other back and we get that looping action happening now so far all of the motors I've shown have been very linear and very flat whereas sometimes the loop isn't quite so obvious to see but the loop is still there it just looks a little bit more jumbled this is exactly the same as this it's just it it's built a little bit different so there we go we've covered the motor side of things have a good at building a few of them yourselves make a big loop make a jumbled Loop experiment around now let's start attaching things to our Motors now an attachment is just a part of your machine that isn't contributing to the motor it is not adding to the movement of the machine it is just tacked onto the motor you found the motors pretty easy to understand right like you you understand how they work well attachments are even easier to understand because they work in exactly the same way you just don't have to Loop them all you have to do is find a segment of your motor that has budgets to be able to add in say an observer and a sticky piston an extra slime block and then you can use that to drag along your attachment the same thing goes for a pushing attachment you just need a little bit of budget to be able to add in a few slime blocks and a regular pist and then you can have your pushing attachment now I must admit this isn't the prettiest slime block flying machine in the world but you can see how it's all working we've got our motor here this is doing all of the heavy lifting and then these two are just being brought along with it this is the fundamentals of any large flying machine look at this do you recognize that does that look familiar to you all the rest of it is pointless it's all just attached to this one tiny little little Loop right here that little Jump Ahead to the mega machine brings up a good point what if your attachment is way bigger than the 12 block push limit well then you add an attachment to your attachment I mean I actually feel a little bit bad because people are generally quite impressed by my giant slime block and hunting block machines I feel like this video might actually ruin it for people when they find out that actually it's dead they're really simple now in this example I was pulling all of linked attachments but you could push all of your linked attachments or you could do a combination of pushing and pulling remember your attachments work in exactly the same way as your motor they just don't have to connect up to form a loop so now that you understand Motors and now that you understand attachments why not try building something a little bit fancy this is my private jet it looks rather lovely it's got some nice details in there we've got a super simple super fast two piston motor and then these little attachments on the side to create the wings and we're even making use of honey honey blocks so that we can have the slime blocks and the Honey blocks next to one another there's not many air gaps now when playing with combinations of Honey blocks and slime blocks it can be tempting to create really really compact flying machines like this motor right here this should work right we've got slime blocks on one side honey blocks on the other side they're not going to stick to one another we've got ourselves a loop but if I activate it you can see it it doesn't really actually go very far and that is because the the slime blocks still stick to the components on the other side so yes the slime blocks and the Honey blocks won't stick to one another but if a slime block ends up next to a piston it will still stick to it and your block push limit will be surpassed very quickly so definitely watch out for that when dabbling with slime block and honey block combined machines so that is all of our Basics covered now it is time to move on to some of the slightly more advanced bits and pieces first things first making solid looking structures now this right here is essentially a regular link attachment chain we looked at one of these a little bit earlier on but it's a little bit smarter and when put next to one another creates a solid wallet of blocks which always looks really cool inside of moving machines we're using strips of slime blocks and honey blocks next to one another in segments and those segment splits are being hidden by the fact that although these blocks here are not stuck to anything they're not attached to slime blocks or honey blocks like these ones are they will be pulled along by the blocks that are attached to the slime blocks and the Honey blocks this is an important thing to remember and it's a very useful tool to have in your toolbox you actually might have noticed something similar a little bit earlier on you see this slime block right here actually isn't sticking to this observer in fact is not sticking to this whole segment right here but it is going to push this slab along which is then going to push this slime block along which is then going to push all of this stuff along and when you use that to your advantage you can end up with some really nice solid chunky looking builds now another thing that you'll see in a lot of large machines is diagonal lines and that is because you can attach your decorative blocks to two sides of your sticky blocks when you think about it even these modules here are just diagonal lines that you stack up next to one another to create a sort of flat area so this is an example of a diagonal wall that moves forward but you could move your diagonal wall sideways or pull them backwards if you want to they're just useful to have in your build just remember when it comes to your walls it's much easier to do diagonals than it is to do flat walls on giant moving machines flat walls are possible though they just require a little bit more prep so you can see here we have our motor and then that's going into this little attachment here which is then going into this attachment which is then going into all of these attachments all of these separate segments now as you can see on the back of all of these segments I've actually got a little setup where we have observers running into Pistons that are pushing this big structure along now it's important to note that there are no air gaps on the inside of this structure if there was as soon as this started moving the whole structure would compress in on itself you need to make sure that there is no air present but the beauty of a setup like this is each one of these individual Pistons can push 12 blocks in a line because there are no slime blocks or honey blocks in this part of the build we're no longer dealing in segments and stuck together clusters it's just good oldfashioned linear straight line 12 blocks so if you wanted to make say a walking house or a moving diamond pile this is how I would recommend you do it you've got your motor and then that attaches into a pusher which attaches into an even bigger pair of Pusher attachments which then goes into all of these Pusher attachments which then push this thing along nice well you may have heard me mention a walking house just a second ago well I've shown you how to do the house part but what about the the walking part let's take a look at some legs now I will admit legs are a tiny bit complicated because there's a few things that have to happen the leg needs to come up and then it needs to move across and then it needs to be able to go back down again there's multiple directions of movement going on there which is a little bit more complicated than anything that we've looked at so far until you think of it as a motor that gets assembled when the leg gets pulled up and then a motor that gets disassembled when the leg gets put down that that then makes things a little bit easier so here we have our really simple leg if I remove this redstone block you can see our leg goes up moves across by a block and then goes back down but what happens if I increase the spacing between our redstone blocks well then you'll see that actually all it is is a regular flying machine that only gets activated when the leg gets pulled up and then it gets Switched Off when everything goes back down and if I remove the Redstone Block entirely well now you can really see what's going on here we have our simplest version of the Flying Machine a push and pull two piston Loop going on so this is my little leg design which I use all the time but I would highly recommend you go away and try and design a leg for yourself using exactly the same principles and once you've designed your leg hook it up to a little motor and watch it hop along off into the distance that's actually quite lovely to watch but I think that brings me quite nicely onto walking sequence is if I walk forward and look down I may notice I don't have any legs if I switch into F5 however I can see that one leg kind of travels past the other I don't shuffle along like this that would be a weird way to get around instead each leg swings by now to get that sort of walking sequence inside of a machine we need to alternate each leg moving forwards two blocks at a time so this one will move forward two blocks overtaking the other leg and then it will stay put while the other leg moves forward two blocks and they'll switch places as they go and we do that making use of these little circuits right here and they're actually quite funny little circuit you see when I hit this button here I'm sure most of you can guess that these slime blocks are going to be pushed along like this and the Pistons are going to come with it what happens next might be a bit of a surprise I mean how did that piston get there surely surely it was stuck to this slime how's it ended up in this position well if we do it again you can see that this piston gets powered and it pushes the slime blocks and the redstone blocks along but this piston is also stuck to those slime blocks as well so it also gets pushed along like this and then when it lands there it also gets powered by this redstone block which means it then pushes the slime blocks and the redstone blocks along meaning that we essentially have a double piston extender so if we inspect this build quickly down at the bottom here we've got our legs we all understand legs now and then up at the top here we've got our double piston extenders and our legs are ever so slightly staggered this leg is one block further forward than this one now if I simulate our motor pushing this line of Pistons forward you can see that that double piston extender will fire and then these Pistons have been brought forward one block which means on the next push this double piston extender is going to fire so we are alternating moving forward two blocks at a time which if I hook everything up to a motor leads to a really nice walking sequence that actually looks fairly natural and cheery this looks this looks really cheery that is the happiest little walkot I think I've ever seen in my entire life but even though it's cheery the legs are quite small what if I want to make a bigger leg well you should have learned from attachments by now that if you want to build a bigger leg you just build two legs and then and then attach them together no one's going to watch my slime block videos anymore are they because everyone's just going to be building their own awesome robots as we can see here if we move our redstone block along the top segment moves which then moves the redstone block out the way of this piston which then it just does the same thing as a regular leg it's just two legs stacked on top of one another now I will say the way that you have to power the top piston of the second leg is a little bit different because if we move the redstone block up and then across we'll run into all sorts of issues with Bud powering so instead we start Bud powered move it up and then update it with this block here but for all intensive purposes we just have two legs on top of one another but surely a leg this big and this fancy is something else surely you've done something different here well look a little closer peer a little bit closer into the mechanism and you may realize that this is in fact just three legs on top of one another put next to one another this is four sets of three legs put next to one another with two legs on top of one another on each side and then another four sets of three legs on top of one another to make up the other edge of the leg and then they've all been just orientated so it looks like one big leg it's just a bunch of legs made to look like one leg so now it's time to admire my armadillo I'll be I just really wanted to build an armadillo I really wanted to build an armadillo but that's a really stupid idea for a whole dedicated video I built a massive Armadillo in Minecraft so I built the Giant armadillo and then and then did everything else for this video to justify me building this Giant armadillo look at it look at his cute little face his little little teeth on the front there I mean it's great I think this thing's fantastic but before I activate it let's take a look at all the various different things so firstly we've got our motor in the middle here all of you should recognize this it's a simple little thing now when it comes to large moving machines it's important to think about how fast your machine should actually be moving as you saw earlier on with the short little legs they looked very cheery and very happy but realistically that probably needed a slightly slower motor so that the ratio of on the ground time and up in the air time of the legs was correct so this motor is quite a big and slow one up at the top here we can see a variety of attachments being chained off of the original motor sequence there's a mix of pushes and pulls going on the top segment of the shell makes use of this setup over here that we saw earlier on the legs are just a bunch of legs stacked up next to one another and on top of one another and that really is all there is to it I know it's a big and it is a complicated machine but it's made up of a bunch of incredibly simple principles so that's enough talking let's kick this thing into life and take a look at it walking across the landscape and I think we can all agree this thing's very satisfying to watch I mean those legs have the coolest sequence just watching all of the segments move separately it's really cool I'm super super pleased with this thing I really do hope that you got a lot of information out of this video I really really enjoyed making it I enjoyed sharing the process of how these machines come together hopefully you have a little bit more understanding of how they actually function which means hopefully even if you're not building them for yourselves you now have an appreciation of how these things actually work you can look at a build like this and actually spot various different elements that perhaps you weren't aware of before I really do hope that you enjoyed and I will catch you all in the next video see you
