[Easy] Creating a CUSTOM BOSS in Vanilla Minecraft 1.19+! (Part 1: Creation)

What but that’s impossible I already defeated you you’re just part of a video and you’re also way easier than last time um hello what’s going on here this wasn’t part of the pumpkin video um I’m sorry what I don’t remember coding that in uh who the heck is oh my God

Oh hello everyone and welcome back to possibly the most anticipated video I’ve ever had the pleasure of working on you see on January 25th 2021 I released a video on this channel about making a boss in vanilla Minecraft that absolutely blew up I’ll be honest I

Never expected it to grow like crazy I was just interested in adding more bosses to Minecraft and wanted to share my methods with others who shared the same interest the video series was popular but truth be told it was a little flawed for example I really glazed over the scoreboard section and

Was more focused on showing what I had done rather than walking through step by step at the same time this was actually because I had already created the pumpkin on my own time spoiler alert I know and wanted to deconstruct my labor into a tutorial after the fact but now

We’re gonna do things better Minecraft is in 1.19 at least it is as if recording I’ve had even more time to mess around with commands and this time we’re doing it all from scratch at the very same time so you can follow along line four line per usual I’ll have all

Of the important commands in my paste bin in the video description but I can’t fit every single thing we work on in there so there might be some emissions that are purely aesthetic commands that you can still do by following along with the videos oh and that reminds me this

Tutorial is for beginners so I’m making this boss at the easy level that said this tutorial will definitely be more than one video because of everything we have to go through so keep in mind these will be coming out as a series as fast as I can edit them all so without

Further Ado here is the official tutorial on how to make an easy level boss in vanilla Minecraft 1.19 and up first things first we have to pick what mob we’re gonna bossify this time last time it was the Stray and while this is great for cosmetic and

Gear purposes as this boss is going to be simpler I figured why not the Pinnacle of all first RPG bosses let’s work on the Slime I know I know not very imposing but with a little bit of tweaking I reckon this guy’s got a shot

To make it big up there with the pumpkin and any other bosses we create in the future but before we even get to designing our boss and MC stacker we need to make sure we can run some tests so let’s just summon a normal slime using commands instead of a spawn egg

For now okay now that we know what boss we’re gonna fight how do we actually summon it to fight well before we actually use some really fancy item detection methods but for a much simpler and easy to follow solution we are just going to use a button if you need to

Contextualize this for your players think of it like choosing an enemy in an arena so if we go ahead and look in our first normal command block here we’re simply going to want to summon the boss at a specific set of coordinates let’s just go ahead and grab the center of

This ring I made for testing which we can do by pressing F3 and then on the right hand side we see it’s 6 negative 61 2. all right so let’s put this together we want to use our summon command and we want to make sure we’re

Summoning a slime and then we can input those coordinates again these are going to vary if you guys are following along and testing in your own worlds make sure you get the coordinates of where you want to summon your testing boss of course we can always go back and change

This later so it doesn’t have to be permanent okay let’s just make sure everything is working so far and we know how to do our Command Basics so if I press confirm and click this button sure enough there we have our slime although I guess it was one block in the ground

So I probably want to boot that y value up by one there we go our slime so what are the actual design steps to creating a boss I mean a slime is great and all but when should we jump into making hundreds of attacks in different phases well let’s take a look

At another Minecraft boss for inspiration ah the Ender Dragon Minecraft’s first true boss it’s been around probably longer than some of you watching this video at this point oh God I feel old and although it’s been updated a few times the dragon Still Remains as the main challenge of Minecraft and a good

Staple to take some examples from so what are some of the things we notice about this encounter well number one we notice right off the bat that it has a health bar that’s usually the best indicator of a boss or event some kind of health bar that shows up on the UI of

A player’s screen that the player then has to cleave through number two that’s a big boy no other mob in Minecraft matches this thing’s size like except the giant I guess if we’re technically speaking of mobs in Minecraft but not but you know what I mean so making an

Enemy imposing means business number three ads well it technically doesn’t summon them you’re very likely to at least accidentally engage in combat with an Enderman if not outright then to clear a path this makes the fight more challenging because the player can’t just focus on one threat number four

Strategic weak points while you could just whale away with Precision aim on a Max enchanted bow the designers intended this fight to have strategy and thought put into it climb the towers destroy the dragon’s healing Source Take Aim and then go in close when it lands and number five different attacks unlike

Most mobs in Minecraft the Ender Dragon actually has unique attacks that it switches between not many but it’s more than just about every other mob running straight at you and dealing contact damage okay I think that’s enough for now so our list as it stands for a good boss

Fight in Minecraft is as follows a health bar it should be imposing there should be minions or other threats there should be strategy involved and our boss should have different abilities we can definitely work with this when designing our slime boss now keep in mind I didn’t say anything about

Difficulty that’s because we’re just looking for inspiration on what separates a boss fight from a skirmish with a tough mob by adjusting our five steps you can make any boss harder or easier as you see fit for this tutorial our boss is going to be on the easier

Side but feel free to bump up the damage or health values if you want something harder okay now that we have a good idea of what we should do to our slime to make it boss worthy let’s start going down the list first up let’s make sure we can

Give our boss a health bar that actually represents how much health it has left and make sure it can update in real time the way we’re going to do that is with the Boss Bar command this is a very specific command that lets you create those health bars like

The one we saw with the Ender Dragon technically they can track anything it doesn’t have to be Health you can use them to track scoreboards or even timers but that’s a challenge for another video for now we just need to go through the process of adding one so we’ll do slash

Boss Bar add and then we’re gonna have to give it an ID this can be anything but it should be something we can remember so for now I’ll put slime King like that then we’ll have to give it a proper name something that the players will actually

See client-side we have to use quotes because it’s in a string and I’ll call mine the king of slimes perfect and if you don’t like whatever you come up with you can actually change this really easily later without messing with any of your code okay now our boss bar is

Created but as you can see we can’t see anything on the top of my screen yet we have to make a few modifications first by doing slash Boss Bar set the ID of our boss bar which is Minecraft colon slime King and then whichever value we want to set let’s go

Ahead and change our boss bars color to Green to match the slime so I can press color and then you see we have a whole list of options that come up I will type green there we go next up we should set the max to be equal to whatever the health

Of our slime is we don’t actually know this yet so I can come back later I’ll skip down to style and this is totally optional but I like choosing one of the notched styles to let my players measure their progress so for now I’ll just do

Notched 10. finally let’s go to Boss Bar set players and we’ll add myself for the purposes of testing and voila it shows up empty on our screen but hang on before we Rejoice I only added it to myself for testing purposes what happens when a new player on your server or map

Wants to see the health bar Without You adding them manually to the player pool well if we actually go back to our summon command chain from before we can start adding another chain command block after it that will add all players within for now let’s say a 20 block

Radius to the Boss Bar pool so if we open this up and type slash boss bar set then again the ID of our boss bar which is slime King we’ll do players and now we’ll do at a with the parameters of distance two dots to say that we’re

Being inclusive of 20 blocks great now make sure this is set to chain and always active as we don’t want to send a redstone signal through the whole thing I’ll press done now when the boss is summoned any new players other than our defined radius of the command block will

Be able to see your boss bar whenever it’s visible just like that which brings us to our next Point how do we make sure that the Boss Bar is actually linked to our slime’s health and that it’s only on screen when our slime is well for that we’re gonna have

To get into the nitty-gritty of the slash execute command specifically the store parameter of it you see boss bars can track all sorts of stuff including data values of entities so what we have to do is link the Health Data value of our boss slime to our boss bar now this

Will be more foolproof once we actually build our slime in mcstacker but we can still do it temporarily for now I’ve put down a repeating command block here that’s also set to always active to make sure this happens no matter what and we’ll want to start with the execute

Command and then we want to type in the store argument if I press space you’ll see it’s asking for the result or success we want the results which will be stored as a numerical value instead of a success which is just stored as true or false now we’re trying to store the

Boss’s Health in our boss bar so that’s what we’ll pick then of course our boss bar ID and then we want to set this as the value of our boss bar not the max now we need our actual run command which will be data yet entity and then we need to select our

Slime King somehow to let the command block know we’re trying to get the Health Data from our slime boss I know we’re going to name him king of slimes so what we can do is type at e and get these little brackets for extra parameters and for now we’ll go

With the name parameter now there are more foolproof ways to determine entities with tags and other form of tracking but for now in our easy boss tutorial I think a name is something easy to follow and can be changed on the fly so we’ll stick with this for now so

If I type name we need two quotation marks to indicate that we’re typing a string and of course we actually need the name of our boss which will be king of slimes but you’ll notice we get an error here saying that while only one entity is allowed our selectors allow for more

Than one entity to be targeted what does that mean well basically because we’re executing a very specific command the game should only find one target for us to read the data of but in theory there could be multiple entities with that name king of slimes so the game says we can’t do this

So how do we get around it well we can actually go back in add a comma in another parameter this time the limit parameter and we can set the limit to be one to say that the game will choose only one entity with the name king of

Slimes to execute our data command on and because on my server at least it will be the only mob named that then we should be fine if you’re still worried about this there are lots of other parameters you can add like distance to say only find a name king of slime

Within 20 blocks but to keep it simple we’ll just stick with these two parameters for now and then finally we need the path of the data we want to get there’s no easy way to figure this out there is a list of data paths in the Minecraft directory itself or you can

Scrounge around on the wiki but from previous testing I know the name of the path we want is Health with a capital H okay that should be our boss bar ready to go alright enough messing around we actually want to see this in action we’ll just need to actually name our

Slime king of slimes to make sure the Boss Bar knows which end to Target which we can quickly add in our summon command and I’ll go more depth into when we get into mcstacker Okay again don’t worry too much about these parameters the game will do it automatically for you when we get to MC stacker this is just to show us that it works now that I’ve cleared myself in the boss pool you can see that the bar has disappeared just to show that

Everything will work when we press this button now when we summon our slime we should see the health bar pop up and give us the value of its Health which as you can see right now is about two and if I punch the Slime you can see

The Boss Bar update in real time thanks to our repeating command block so far so good but there’s one more thing you might have noticed we need to fix with our boss bar just before we move on to MC stacker after our slime boss is dead

The bar is still at the top of my screen there are a couple of ways to fix this however the first is simply removing the Boss Bar once the boss is dead this is quick and efficient but problematic if you want to have your boss be summoned

More than once as you’d have to remake the Boss Bar every time another option is to just set the Boss Bar to simply be invisible as that is a parameter once the Slime king is dead this is great because we could add a command in our

Chain that just turns the bar to visible again once the boss is summoned but the bar retains all old players that once saw the Boss Bar even if they’re more than 20 blocks away so if you’re playing Survival elsewhere in that Village you’ll still see the Boss Bar pop up so

For now until Mojang Updates this the best way to kill two birds with one stone is to Simply do slash Boss Bar set the ID of our boss bar players with no more parameters if I just press enter you can see that that actually clears all players within the boss pool your

Boss bar is still there don’t worry you’ll just have to re-add players to the pool again when you want to see it which we’re already doing in the sum emboss command so as for where to actually put this command we’ll eventually want to include it in a boss

Death command chain but for testing purposes we can just put it in a normal command block with a button for now just like that we should also set up a kill command for our boss so we can do some rapid testing which I’ve already done here this is

Just a simple kill command with the entity tag and then again selecting The Entity by the entity’s name king of slimes so let’s go ahead and kill off our boss and then clear the Boss Bar which you can see disappears with the command but don’t worry it is still

There it will show up again once we summon our boss and just to show that this is a closed loop let’s go ahead and kill the boss again and clear the Boss Bar look at that we have everything for our boss currently working in four command chains like I said at the end

This will all be automatic but for now we’ll keep it all manual just for testing all right that was a lot of setup but now that we have our first step out of the way we can move on to step two making our boss imposing by changing the attributes to be stronger

Than that of a normal mob so as most of you know by now it’s time to head over to olmc stacker alright welcome to the command Creator’s best friend mcstacker here you can generate virtually any command line in Minecraft from a handful of drop down menus I cannot explain how

Much time this website has saved me and I hope it does the same for you now we want to create a boss that spawns with attributes when we press our summon boss button so let’s just select the slash summon command as that’s the command we’re already using great now we get a

Whole bunch of different fields first we need to fill in a few of our parameters to keep things in line with our previous testing we need to click this drop down menu here and change them up to slime our summon coordinates to be that of

Where we want the boss to spawn and also make sure this custom name tag down here is set to be king of slimes spelled and capitalized the same way we have it written on our health bar command I should take a pause here to remind you

That this stage of the boss creation is completely up to you if you want to follow along word for word so you can get the hang of making a boss then great but if you want to use this tutorial to make a boss of your own then I suggest

Changing the parameters like name potion effects and others to be whatever you want your boss to entail just remember to stay consistent if the name of your boss is ultra Beast here then it has to be ultra Beast everywhere so now for the fun part we have the basics of our slime

Set up but now we need to make it more like a boss well the first thing we should change is set custom name visible to always be true this makes it so players will always see the name of the boss above its head next we’re going to

Jump down to Max Health as I think we should establish a base Max health for this slimy adversary once again we could look to the Ender Dragon for inspiration we don’t want our simple slime boss to be as tough as the final boss of the

Game but we do need some sort of scale to base our attributes off of according to the Minecraft Wiki the ender dragon has a max health of 200 hit points which equates to 100 Hearts as health points are represented by half a heart each on the other other end of the spectrum

Let’s look at one of the most common enemies in the game the zombie these guys have a Max health of 20 or 10 Hearts that’s a pretty big difference with some quick math the Ender Dragon should take about 10 times as long to kill as an ordinary zombie and that’s

Before we add any fancy attacks and other strategy into the mix so by raw stats alone we want our boss to be tough and seeing as it won’t have as much maneuverability as the Ender Dragon does I think giving it a big Health bot to soak some hits would be okay let’s set

It to 120 Health which will come out to be about 60 Hearts nothing crazy and we can always tweak this later if we feel the boss is too strong or too weak but now that we have a base point we can continue to build this guy out next up

Let’s talk damage technically mob damage values change based on the world difficulty but I’ll be presuming that we play on a normal world so my damage values are based on that the Ender Dragon in a normal world does 10 damage with its melee attack or 5 hearts a

Zombie only does three or one and a half hearts and this is all assuming the player has no armor as well so the values may be even lower so the strongest boss in the game does just over three times the amount of damage one of the most common enemies does

That’s not actually very much when you think about it but the Ender Dragon supplements this with varying attacks that do different amounts of damage plus players only have a Max health of 20 or 10 Hearts without golden apples or many other modifications of course I imagine

That the player will be spending a lot of time trying to get close to the boss and dealing with other enemies they will add later on so I want to make the damage the actual boss does somewhat strong let’s set it to 7 for now for

About three and a half hearts worth of damage alright so we have damage and health what other attributes can we change well the other default one would be movement speed right here but we probably don’t want a large slime King flying around the map so I actually want

To decrease the king’s movement speed slightly but this is where things get tricky movement speed in Minecraft is surprisingly difficult to calculate as it is you’d think a value of one would mean the default movement speed a mob can have but each mob actually has individual movement speeds that offset

This value and the formula for calculating this is confusing at best even the Minecraft Wiki sheds almost no light on this which is something I may want to delve into in a further video but for now just know you may have to play around with different values before finding one that

You enjoy and what’s worse is slime’s movement speed is actually based on their dimensional length as they hop a distance relative to how long they are rather than moving across the ground like most mobs luckily I’ve already done some preliminary testing so I have a

Value I think I want for my slime but feel free to play around with this number yourself to get something you’re satisfied with for now I’m going to set it to 0.4 which is maybe two-thirds slower than a normal slime of our Target’s size oh speaking of size this

Is a parameter that only a few mobs in Minecraft get to take advantage of those being slimes magma cubes and strangely Phantoms the size parameter does what it sounds like it allows you to change the scale of a mob it can’t be smaller than zero though so I’ll have to scratch my

Idea for making mini slime chests for now regardless our step two was to make our slime imposing and what better way to do that than to physically change the size of the Slime play around with this value as much as you want because you can get some crazy big slimes but I

Found in my own testing that a size of eight should be pretty good for what we’re trying to do so with all those attributes set we have a pretty good basic boss if we go up to the top right here where this box is we can go ahead

And copy the commands to head back to Minecraft to test it out don’t close this tab though as we’ll have to return here later to give our slime any other effects as well as determine what loot it drops Plus in case you want to change any values it’s not the worst thing in

The world to remake but it’s just so much easier if you just keep it all open like this okay with our Command now copied to our clipboard let’s go ahead and replace our original summon command with our new one and now all we have to do is test it

Ten there we have it quite an imposing large slime indeed sure enough its health is still tracking on our boss bar because we named it properly and although it’s quite hard to tell at this size it is hopping around slower than a normal slime its size would be now let

Me just warp over to survival to test the damage and there you go exactly three and a half hearts just like we wanted a rousing success but if you recall we’ve only tackled two out of our five steps so far so in the next videos we’ll have

To be looking at ways to add other threats or minions devising a strategy to fight our boss and then giving our boss new attacks you now know enough to experiment with different attributes on MC stacker and really make this boss your own but there’s one thing I didn’t

Mention about our King Slime here specifically what it is that slimes do best but we’ll get to that in the next video as usual thank you all so much for watching even just this first part Took a ton of time to produce so if it helped
