Dissecting Minecraft #10: Mob Spawning Part 1 | Minecraft 1.13

Toward the geeks and nerds welcome to another episode of dissecting minecraft that I’m here with methods again as usual we are the Laurel and Hardy of Minecraft today you love that don’t you and today we are gonna be talking about mob spawning yes so before we get into

That I’m just going to say that we’re going to cover this subject in two episodes so today’s gonna be more about the kind of theory behind it and we’re going to be talking about numbers and that kind of stuff and then next week we’re going to look at some examples and

We’re going to get into a bit more detail and show you some tools about how to create mob farms alright so that is the plan for this week and next but before we get into box falling we’ve got some challenges to look at so we’ve got

One here this is from a koi so he he sent one in the last week as well so two weeks in a row so forth on a koi and the challenge for this week was to create a flying machine that had a purpose that had some kind of practical application

And so yeah this is what he did so these two machines are both his and they they create a nice way so this is for your boat your boat roads so I talked about his methods or it’s not really much to talk about it so instead of using the

Rusted ice would CEO Otto frost walk up what’s directly to basically form infinite sources he’s using the water lock blocks which you can indeed move if you use a less than three game take pulse right so at some point they fixed it at somebody they were completely

Movable and then for some reason Mojang didn’t like that and they tried to fix it but they forgot about rock dropping right if you have a sticky piston and it gets powered shortly enough that it block drops then it will actually still move the water source with it and who

Studies and those motor blocks have to be just directly pushed by the piston I can’t be like via and has to be a piston pushing them directly yes you cannot attach them to slime or anything else has to be the piston itself block dropping it because only the block

That’s getting pushed directly by the piston is getting drop yeah yeah so yes I see there’s this this fire machine that pushes these blocks these water lock blocks along and then you correct the source way so this machine here gives you a 1 a 1 thick ice way and this

Machine gives you two next to each other so ice place the same machine but let’s kick these off and see if they work hopefully I’ll do it correctly let’s find out there we go so there’s the flying machine moving along and it’s pulling this frost Walker

This almost Oh Ross Walker behind it and that’s a that freezes the ice and then of course yet the as method says we pushing these multiple blocks which keeps them all to move it the beneficial part about this system here that’s not using the frost ice itself is you can

Make those way faster says we see here this is a 10-game take engine and you can also use the defrost Walker boots themselves they’re basically making a frosted ice and then pulling the frosted eyes forward so it Mets immediately forms an infinite source and then

Freezing it again but it is a lot slower I think that’s like 19 game takes per block if you do it fast and just does this really dope to pick Atlanta to nose yeah that’s pretty cool so yeah thanks a lot okay very good stuff yeah so this this

Other one over here just wears the same way but they so kind of like to to to stuck together but yeah we move on from that and thanks everyone else for all their submissions and yeah even if you’re watching these episodes like in the future then feel free to still put

Your poster and post your challenges on there so we can have that so kind of read it those reddit threads grow over time there could be a good resource for other people to take a look at alright so let’s get on with the topic of the day

And that is mob spawning alright so let’s talk about mob spawning and we are inside this this glass sphere so I guess this is a good place to start so methods do you wanna kick it off alright so let’s get started so dis let’s look you where I’m standing right

Now will be our fixed point for a player so if a player is standing here mops cannot spawn nosfy around him for 24 blocks this is the screen or lime sphere we’re standing in here nothing can spawn inside here and this includes the sphere itself right

And then the next field we have is the blue sphere and this has a radius of 32 blocks and this is the area where mobs can spawn but cannot be spawn so anything that spawns inside here yet again including the blue glass itself can spawn but will never despawn since

It’s too close to the player and then on the outside we have the big red sphere and it is a radius of 128 and this is the Mex distance mobs can spawn anything further out there this will immediately despawn yeah now this is a bigger sphere

I think I think a lot of time I think everyone forgets just how big this is so you think about that that Glaus block just inside there look at where that is and a radius of 128 blocks in a sphere comes all the way out to here this is

Actually quite a big area and so we’ll talk about things like Bob phones are conditioned in the area things like that but yeah it’s a big undertaking to to deal with this area for sure oh yeah and it’s basically already it folder ranges in conditions so let’s get over here to

The side and talk a little bit about how the mob spawning algorithm actually works so the mob spawning algorithm it runs in this huge area around you but it doesn’t run all the way up it only checks up to the ice block that blocks skylight right so that means if we for

Example place a stone block right here and for this block it will only check up to this stone block here for a mob spawning rhythm and over this it will stop and no longer try to spawn mobs and this is also seriously important because it defines the chance that a spawn

Attempt is actually successful mm-hmm so for every chunk in this area it’s the 15 by 15 trunk area centered on the player it always checks what is the height and then it says okay let’s say our lowest y-value possible would be y1 because of mob spawning attempt always needs a

Something to spawn on so we cannot have a spawn if you can have spawn attempts at y0 but they will never succeed so y1 is the lowest possible and this means we have a one in two chance that is for attempt succeeds so let me just sorry

Let me just interrupt you there so the the height you’ll talk about that is that is per chunk or is that per block per block a block right okay per block so right here we have a one in two chance that is mob spawn succeeds and if

You just place a block here or let’s say here then this red stain glass block has a one in three chance to succeed a spawn attempt since it’s actually as a higher Y value and therefore the chance it takes those two blocks here to spawn mobs in this one and this basically

Means it always increases by one so if you have a at four then we have a one in four chance five we have a one in six chance at six we have a one in seven chance and so on so it for example by 40

We have the one in 41 chance that a spawn attempt actually succeeds right and so that that’s why when we build firms there’s lots of talk of build as low as possible in the world with less because your spawn attempts are more likely to succeed because every game

Tick in this fifteen by fifteen chunk area there’s three spawn attempts happening hmm so the lower you go the higher is the chance your spawn attempt that’s happening actually succeeds meaning two more mobs you get in the least amount of time right it’s very okay so the next scene what happens when

In spawn attempt actually succeeds it selects a mob type to spawn so let’s say right here where the limestone class blockers it selected a zombie the conditions are all met it has enough space it’s dark enough it has a block it can actually spawn on which is usually

Not a class block but we’re using the CEO for demonstration so when it comes to selecting a mob how does it what does it take into consideration when it picks them up so I imagine so first of all like that dimension is important and the biome is important and dimensional the

Biome the light level if it’s a slime chunk all kinds of things and we will cover this more in the next episode as well but let’s just say it selected it had a spawn attempt here on the lamps stay in class block it succeeded and it selected a zombie so

Nowadays a thing called pecks boning and that is basically you don’t see usually once only you see multiples and Ernest in most mobs they have a peg size of or and that means it can spawn up to four zombies right since what happens it selects the first zombie it succeeds the

Spawn attempt and then it randomly goes five up to five blocks into X and z direction so that means it can go one two three four five one two three four five and it could spawn another zombie here I just marked them out with the filo

Blocks right now so let’s say it’s for next zombie here yep and it will do it again since our pick size is 4 we only spawn two of them in yep and I will do it again let’s say it spawns another zombie here and then it can also spawn one more here

Yep and every step it does here it also checks the mob cap so we have clips on the server and it means you can maximum as one player have 70 hostile mobs at a time in the game good and there’s also different mob caps there’s a mob cap for hostile mob caps

For more awesome ops there’s a mob cap for passive mobs there’s a mob get for ambient mobs and for bottom ups we talk about an sick okay but the important part is it always tries to wander up to five blocks far away and then tries to

Do the pecks porn hmm okay this also explains why you usually want to extend your roof outwards further than you need for a light level or even on the spawning layer itself because let’s imagine this red chunk here’s our mob farm yeah and we do have those blocks

Here even though they are not spawn herbal since it’s glass it’s can still to de-spawn attempts because they’re not blocked by a full block or anything and I can say I want to spawn them up here and then it does all of this and that says okay well it’s

Glass I’m failing but my pig spawn attempts can still happen and then it goes five blocks over right still fails and then it goes again five blocks over let’s say two here and suddenly we are inside our mop firm and we can actually spawn them up right so even though we’re

In so even when it’s doing them up the pack spawning even though it’s failing to spawn an actual mob on a spice it will continue and cities finished going through the whole pack sighs exactly as long as it’s not hitting a solid full cube right so let’s say we spawned a

Zombie mmm we have a line of blocks here inside of our farm for whatever reason firing or we just need this line of blocks here and it hits the stone block then it will immediately abort right and that is the reason you never want solid blocks here at your feet

Level of the farm you could use stairs or slabs all kinds of things you can use there it earned a full cube and they will not block it but those full solid opaque blocks will abort spawn it’s right and so that’s why we say is for example in

Nether pies phones we see like a platform of leaves that come out from the out from the platform so if that can encourage extra spoons because of the Pacific we basically pulling picks spawn attempts from outside of our farm into it now we can’t sew it so when we say

Putting them in we can’t but force the pack to spawn this in this direction but it gives us a chance for some extra spoons exactly it’s always just a chance that it goes from outside into your farm right so you’re basically just increasing the chances to get more mops

And that’s and that’s the same reason for if you’re doing like a conniver world farm where you have a roof like a slab roof on top so we have slabs because they’re not supportable first start off but also we normally extend the roof now is about 15 blocks of

Another so how do you do 14 blocks out to right to get why level like level zero yep but it’s actually beneficial to make it more so most peg sizes are for for hostile mobs that means you actually want 20 blocks extending right 20 bucks it can

Four times five blocks is 20 so if you go 20 blocks out it checks the highest opaque block well let’s say our roof is here and be extended – let’s just do it until here doesn’t really matter so all of these blocks here up to this top

Block will do spawn attempts and since there’s nothing else here they will not get aborted and then it can actually wander inside of the fall right so that’s why I have the extended verso so nobody would have slabs but it’s the same difference so if pax Bonin and even

Now it’s just air here they would fire because there’s the block it picks is no block this vulnerable but the pack the pack saw is the pack spooning will continue until it’s gone through everything everything in that and I saw in a pack size exactly yeah okay that’s

Great okay fantastic okay and it’s also the whole shenanigan about the Leafs and now you extend it and let’s just talk about some other random information it’s very important so what caps if we just do in a chat /spawn mop caps you can see they’re a little bit

Different now because we are two players but we will explain this run so we have two monster mobcap this is all the hostile objects like zombies spiders skeletons all of that stuff that it takes you that is usually if you’re alone 70 mobs yep and we have the

Creatures that is passive mobs like horses pigs chickens basically and it’s there’s a mob kept of ten let me have the ambient mop which is basically only the bet that’s also ten no sorry it’s 15 got changeable 13 and then we have two water creatures those squids and fishes

And those are also 15 so now every player has heads to the mop cap since we’re right now we were in the same chunk it only gets added a little bit so it goes from 70 to 85 from 10 to 12 from 15 to 18 and from 15 to 18 again yep so

But the more chunks that we both float the higher the mop cap gets so if I move two chunks far away and we do spawn off cap again we’re now in a mob cap of 96 for the helstem ops right and if I move even further away we’ll go even further

And if I move really far away real quickly we will see that it’s now actually double and it’s also not player specific so for example if I’m now here in this huge glass area and you have a huge stone area you will get 140 mobs it’s not based on the player right and

That also explains why a lot of people are witty player servers always have problems with their farms not really spawning term ops you see in the video so that means basically I’m in my perfect condition perimeter I have a mob firm with let’s say 1000 spawning spaces from ups to actually spawn

And it works super good and then you suddenly lock in in a normal area and you have 75 thousand pellets spawning spaces around you suddenly my spawning spaces cannot compete with ya yeah and you basically get 138 mobs and I get yeah I think so I think that’s one of

The one of the number one comments that I get on some of the farm videos that I’ve done is that people say that like I’ve built this farm and it’s not working and I can guarantee it’s one of the two reasons is either the the area around hasn’t been conditioned properly

So there’s lots of spawning space outside of the farm so I’m off to spawn outside of the farm is that have inside it and then the other reason is like you suggested there it’s on a multiplier server and other players are filling them up cap and that’s again why you

Don’t get get most winning so safely exactly there’s one more very common problem in Tennessee a render distance right so if you go below render distance 10 as we know mobs can spawn up to 128 blocks far away from you if you go below render distance 10 they can actually

Spawn inside of lazy chunks which then they will not eat no longer T spawn since they’re lazy loaded and it basically makes it so you’re over time create a mob switch around yourself right okay so yeah this isn’t the mova is if you can have at least the render distance of

10 yeah every distance of 10 and have a properly conditioned perimeter and tell the people to log off okay yeah that’s good okay this was basically here the mob cap is shared with all players no matter of position that basically means no matter where you are and I am people share a

Mob cap and it gets basically if we load the same area it gets up by 15 and if we load our own areas it gets double okay and there’s a nice little mathematical thingy on the wiki where you can actually calculate exactly to each chunk

I move away how far it goes up but it’s fairly complicated really trippy okay then and as a very important fact mops cannot spawn inside of other entities mmm what does it mean a mob cannot spawn inside of another mop or a minecart or an armor stand or things like this right

And that and that that’s a change II 1.13 I think is that right it is a change in will not search it went up to 112 takes from 190 to 112 they spawned inside of each other hmm okay then another fact mops cannot spawn in a radius of 24 blocks around the

Original void spawn right yeah a lot of people don’t know yes so if you start doing a map form at your spawn point then or he’ll be well spoon then you’re gonna have some issues a lot of people for example open a creative world and start messing around with more

Farms and pull up move away and then they wonder why they have really low rates and that’s usually because they write at words for so make sure you move to chunks far away from where he spawned in it okay then basically a bunch of standard stuff host time ops excluding slimes

Neat light level seven although were to spawn and it excludes most never mobs besides with our skeletons so because they never obviously has a lot of lava Pikmin and places and cars stay all we cannot completely canola light level they do not yep besides places they actually took care

It has to be a buff light level 11 yeah okay then another fact besides water mops all mobs need two blocks of headspace hmm so what does that mean I have this little C put up here maybe let’s just move it to here to make it a little bit more

Accessible so let’s imagine a bet wants to spawn here here it can actually spawn yep and here it come so even though the bet is really small the game always checks for this headspace here and if it’s a glass block or a slab or a hopper or leaf block or something like that

That isn’t a full cube and not opaque then you can actually spawn you though the bet can spawn here but if it’s a full block and it is opaque it cannot spawn you even though it would actually fit it still checks the soul area okay and that’s safer spiders is where I

Think right exactly so if the spider could spawn here but it couldn’t spawn right now the other question here which might be applicable is baby zombies so I correct me if I’m wrong but I don’t think baby zombies would spawn here because when it comes to baby zombies

The game picks a mop to spawn first which is the zombie and then it would pick a variant of that if it could spawn so weak so basically just a whole lot spawning algorithm it says I want to spawn a zombie can outfit here and for it for a zombie to fit it

Actually needs to space yep and then it does the pic spawning and everything and right before it finishes everything it says like okay what type of zombie am I actually gonna be I’m gonna be a baby yes I could be a baby could be a villager could be a normal zombie right

I think zombie villagers actually have their own little scene since 1:30 okay so that is no longer here zombie villagers also have a smaller pig size did normal zombie snow okay so for example normal zombies can spawn up to a pack of four bobs some be malicious only born okay

Okay then again mops need a solid top surface and an opaque block to spawn so what does that basically mean it means mops cannot spawn on chests mops cannot spawn on a bottom slab since it does not have a solid top surface yeah so let’s just get a quick example of the things

That repeaters and this here has a solid top surface us can see you it’s flat solid it’s full block size basically this here doesn’t yeah then the glass now the glass has a solid top surface but it’s not okay and that basically defines what a mob can spawn and what about Burhan

Bedrock and Perea blocks are two exceptions to this whole thing ii bedrock and barrier blocks are both specifically made spawn proof even though they are solid and opaque again to have a solid top surface okay this of course excludes water mops we will talk a little bit more about

Spawn conditions for those in the next video because they’re very specific and there’s different ones for different water mops yep and it’s yeah they also exclude spit okay then we have peso flocks passive mobs like animals they meet light 11 9 or higher and any grass to spawn oh and it

Excludes mushrooms mushrooms need mycelium but still light level 9 okay also another interesting fact is pests from ops don’t use this hostile spawning algorithm that we just talked about they use a completely different one and it only happens every 400 game ticks right so every 20 seconds it tries to spawn in

Passive loops right so that’s what we’re also covered this in the next episode way more in depth right how exactly looks so this is that’s why in your world you’re gonna be covered when it’s nighttime you’re you’re surrounded by lots of mobs but not there’s lots of

Hostile mobs but not many how many passive mobs now in a normal world you don’t see pest is mob spawning at all that’s right okay so in a normal world there’s also there’s always your spawning conditions for for peso flops like pests forms can respawn but they

Also generate with the words if you generate a chunk and let’s say it’s in a Plains biome it can generate pigs or chickens and that usually means in a normal word that you do not specifically condition you always have more in ten all right since the passive mob cave is

Only ten mobs that’s basically always there I say unless you specifically condition your world foetus so when those passive mobs generate with the chunks that I check the mob cap of the time or that I just spoon they completely ignored make sense okay okay and then lastly the microvidia

Wanted to mention they have a really nice spawn tip it’s a little bit outdated 413 but the whole conditions part of it the spawn conditions is still very accurate and it would highly recommend you check this out because there’s a lot of informations for each and every single mob what exactly they

Need how exactly they spawn in and what conditions they have to use okay we must move we get a link in the description to that so yeah just make sure you ignore all the algorithm parts and everything just a spawning conditions because it’s a little bit of okay

Yeah and it’s basically it for today all right awesome all right so that is about it for this episode of dissecting minecraft now this week we’re not going to give you a challenge like it like a normal house challenge that we have done before because this is just open theory based

And but that will be one next week but for this week I think what we want to do is we want to encourage you to give us as many questions as possible in the comments let’s just make sure that we’ve done that we’ve explained this in a way

That will make sense so if there’s anything it didn’t make any sense or if we’ve missed anything out then get those get those questions in the comments and what we’ll do next week is what cover as many of those as we can now before we delve into into more

Details alright so if you enjoy the episode and it was useful then please hit the like button and if you are new then feel free to subscribe and if you’ve got any comments or suggestions or any more than the I just asked about then get it in the comment section

Alright bye geeks until next time I will see you later
