Umm... "How Did This Happen" -Bill Wurtz Yeah... If you thought that Minecraft's items were safe
from my wrath, it's time to think again. I wanted something new to break, and boy did I find it.
So let's quickly set the stage. Every single item in Minecraft has some limitation for how
many of that item that you can stack together. These values start at 1, and end at 64, with
many items landing somewhere in between. Basic stuff. But, have you ever given any consideration
as to how Minecraft stores these values? Have you ever wondered if they can be broken? And have you
ever thought about the ramifications of wielding 64 totems of undying at the same time.
Haha. Let's go ahead and get right into it. Today's video is brought to you by
Opera GX’s exclusive gaming platform, GXC. Now yes, this is an ad, but I honestly
really enjoyed playing BlastNet on GXC, as it reminds me of Geometry Wars, and I just
enjoy fast paced high strategy games like this. This one session lasted well over an hour, and I
scored over 79 million points in a single game. But in much the same way that I break Minecraft,
I don't think I was supposed to get 74,000,000 on one single hit, even if it was during a really
high combo. What can I say, I break things for a living. So we'll call it 5 million legit. Think
you can beat that score? Well then, give it a try. I also really dig GXC's challenges system, because
I've got a speedrunners mindset. If you win the Challenge of the Week, you'll walk away with a
gift card in hand. Play games with thousands of users, check out the most popular games, and even
create your own games. Access to GXC is completely free, but you can only get all these features
by using Opera GX, the world’s first browser for gamers, also available for free. Check them
out via the link in the description, down below! This is quite a complicated subject, spanning a
wide variety of different Minecraft versions, so allow me to unpack it some more. Throughout almost
all of Minecraft's lifespan, each item stack has been limited to 1, 16, or 64, depending on the
item. I feel like the reasons why intuitively make sense. Tools, weapons, and armor are only
meant to be used one at a time, and certain items behave unexpectedly when stacked together. Take my
previous example, the totem of undying. Normally, you're only meant to hold one at a time, with it
being consumed when your health reaches 0. But having 64 of them equipped at the same time means
you can die 64 times without having to pause and re-equip one. This also saves on inventory space,
as you wouldn't even be able to hold 64 of them at a time without using shulkers or bundles. Many of
Minecraft's items have interesting behavior like this when you break their intended stack limit,
all of which is possible in unmodified, vanilla, survival Minecraft. Now that I've explained
why you may want to break the stack limit, allow me to introduce how we'll break it. First,
by over-stacking, and then, by under-stacking. Over-stacking items in Minecraft means to cause
that items stack to go above it's intended limit, often times allowing for it to go above 64 as
well. Right now, I'm in Minecraft 1.12, doing a glitch that allows for me to convert the stack of
items I have within the crafting UI into the item that I'm dropping and picking back up. Once the
glitch itself occurs, the two item totals combine, and the amount of items I get completely ignores
whatever that items intended stack limit is. Depending on the version you're playing on, when
things are stacked beyond their intended limit, you have to be careful, or really careful as to
how you move these items around your inventory. With this 1.12 instance, I can use the 1
through 9 keys on my keyboard to shuffle items all around my hotbar and inventory,
but only if the stack size is 64 or lower. Stack sizes above 64 break apart if I attempt to
move them out of my hotbar or offhand slot. The way in which over-stacking behaves varies wildly
depending on what version that you're playing on, but I chose this example to give you a good
initial idea of what nuances to look out for if you try this glitch for yourself, no matter
the version. We will get into more examples you can try for yourself later on in the video, but
for now it's time to move on. That just about covers the fundamentals over-stacking,
so let's move on, to under-stacking. If you're anything like me, the kind of person
whos fascinated by these sorts of glitches, regardless of whether or not they're useful
or even possible in modern versions, one, subscribe to the channel if you haven't already,
but two, you'll probably enjoy messing around with under-stacking, even if it's not quite as useful
on it's own. Under-stacking allows for you to get items with a stack count of 0 or even lower. I'll
be using Minecraft 1.8 to do both of these things, and then, I'll show you what you can do with it.
This specific glitch can be done by placing the desired item into the first slot of a chest,
freeing up your first hotbar slot, igniting a block of TNT next to the chest, and then hovering
over the item and absolutely spamming the number 1 key on your keyboard. If you're lucky, the item
with a stack count of 0 will enter your inventory. From here, you can use a dispenser to
further reduce this items stack count, all the way down to... umm... uhhh... is it...
ever gonna stop? No, but it's also just a ruse. If you ever encounter a circumstance where the
value goes below -128 or above postive 127, it will just roll back over when the world is
reloaded. The easiest way to know what the value will land on upon reloading the world is to take
whatever number you have, and add or subtract 256 to it until it's is somewhere between those two
numbers. In the case of -187, adding 256 will cause the reloaded number to be 69. Nice. The main
utility of under-stacked items is actually for item duplication. The items that this dispenser
is... well, dispensing, are actual items that you can actually pick up. During this version of
Minecraft, dispensing an item only subtracted from it's total until it hit exactly 0. But if 0 is
never reached, the dispenser just never stops. Now that we know how to over and understack items
in Minecraft, what else is there to do with it? The biggest utility by far is the ability
to conserve inventory spaces for things that typically cannot be stacked together. That on it's
own is huge, especially when you stack items that have a durability bar. The bar for that item goes
down like normal, but when its durability drops to 0, the item count just falls by one, and then
the durability bar resets. If you're playing on a version where overstacking can be performed, you
can set yourself up to basically be unkillable, as you can stack armor, weapons, and
totems. Those of you who have played on certain anarchy Minecraft servers probably
know all about this. You know who you are. Diving even deeper into this, if you shift click
an overstacked item into an enchantment table, uncraftable potions can be, well, crafted. Given
that over-stacking usually means duplicating items, all of the benefits of duplicating items
come into play. While the usefulness of over and under-stacking doesn't quite stop there, that
does cover most of this glitchs practical uses. Throughout the years, there have existed plenty
of ways to obtain overstacked items. In the first upload of Beta 1.3, every time you would die
or start a new world, you would spawn with a debug inventory that included a stack of 63 beds.
This is the same version beds were introduced in, so it's kind of fitting. During 1.6's
development, saddles specifically craftable for horses were tested, and could stack up to
32. They were then removed 2 snapshots later, but if you loaded a world from those snapshots
in 1.8, you would find that overstacked armor stands would take their place. Overall, there
over a dozen ways you can perform this glitch, and for that, and so much more, I'll send you
off to the Minecraft Discontinued Features Wiki, where I got all of the information for this
video. This is a website that I only just learned about recently... and it is a godsend.
It's still a work in progress, but I seriously applaud the community effort, and I know that this
won't be the last the that I make a video covering information from this wiki. As far as this video
is concerned, that just about does it for me for now. I hope you all enjoyed, subscribe if you
did, my name is AntVenom, thanks for watching.
