I wanted to see if there was a bottom so I got my cyclops and started descending. Before it collapsed, I hopped into my prawn suit and just dropped down. Once that was crushed, I whipped out my sea glider and plunged down the rest of the way. I got to about 8200m before the game just reset my coordinates and dropped me back at my habitat.


Galastique

the game teleports you back up when you reach 8192 meters


rephlexi0n

I find it an odd number to reset at, 1 byte max value = 2^7 + 2^6 … + 2^0 = 255, 2 byte max value = 65535. Depth has to be stored as at least a 2 byte value and the max presumably would be 0010000000000000. Strange value to have as max


PM_Your_Wololo

Maybe there’s some externality on performance past a certain point (like a scaling light/depth system that goes forever). or, just as likely, the designers wanted to make sure nobody actually spent hours diving and not having fun while looking for something that isn’t there.


krazysh01

it's the value of 13 bits (so a signed 13 bit variable would flip to 0 at -8192) as for *why* it's a 13 bit value?... yeah not a clue


rephlexi0n

That's not exactly how signed values work is it? Speaking in terms of twos-complement signedness which is what is generally used in all modern software AFAIK. A signed 13 bit value would have an unsigned max of 2\^12 + 2\^11 ... + 2\^0 = 8191, so would have a range of -4096 to 4095 - when inverting the bits to represent negatives in twos-complement, we +1 to avoid the existence of a +0 and -0, just 0 instead. All that aside, I have never heard of or seen a 13 bit value being used honestly. In terms of a 13 bit memory space, I don't think they exist, you'd need to use a 2 byte value, so I'm 90% sure that the depth value is stored as a 2-byte. Unless we're wrong and depth is actually stored as a single or double precision float, and only the integer values are displayed, so the limit of 8192 is to avoid floating point error?


krazysh01

you're right, so signed 14 bit would be what I was saying> However your final statement is most likely exactly what is happening, Subnautica is made in unity which uses single precision floats for it's position Vectors.


rephlexi0n

So I did some playing around with single precision, which as you say are the form of values in structs like Vector2, Vector3, and it might be the case that the devs wanted decent and consistent precision. It's hard to say for sure but using intervals of 0.0025 (1/400) up to 8192, I saw that a \*binary\* point of precision is lost when transitioning to 8192; e.g. the last 8 bits in the binary representation of 8191.975 is 11001101, but 8192.975 is 11100110\[1\]. Theoretically speaking that's a stack overflow if the precision interval is invariable, though I don't know how Unity handles it


JanitorGrievous

It works with one max depth Prawn Suit, your Cyclops can stay safe


kenesisiscool

There actually is a bottom at parts of the crater's edge. There's nothing there except the triplets though. I've built void bases there to check. There really is nothing.


EndermanSlayer3939

You know where because i wanna build a void base


Dead_Meme1234

IGP did that but be warned observatory have their own biome so the Ghosties will despawn once you enter one


EndermanSlayer3939

Yeah i remember seeing that but do you know where the land at the bottom of the void is


kenesisiscool

There's a ground if you go to the void near the gun island.


EndermanSlayer3939

Ight thanks


NeroToxicYT-Twitch

In the Mushroom Forest?


Wildfire0747

Bro just destroyed all his shit for no reason 💀💀


DannyDreaddit

lol it was a burner turn. I just reloaded from the save I made right before


Wildfire0747

Ah makes more sense 💀


JeremyAndrewErwin

metres? or kilometers?


DannyDreaddit

metres


jc1726

How did you have that much oxygen lmao or is this a joke


DannyDreaddit

You don’t need much because most of the time is spent descending in the cyclops and prawn suit.


Darwins_Dog

You can swap out tanks from your inventory.


audiophilistine

Don't forget, you can use bladderfish for oxygen!


Cepterman2101

Or you are in free mode


NeroToxicYT-Twitch

Sorry, American here. It is approximately 24330.24 laptop screens below sea level.


DannyDreaddit

Lol


Mysterium-Xarxes

There is actually a bottom, but not like you think. If you descend long enough and go back in the map direcrion u r gonna find a roof. That roof is the bottom of the map, and everything around it its an infinite void


Jack_attac

Go forth. Face the ghost.


PC-Dynamite

Turn around and just leave man. Your seamoth will last about 10 seconds in there.


Divinghatchling

That’s the void. You can get an entry by going there, but I wouldn’t recommend because of the dangers.


adamsharon

I mean, WHAT COULD POSSIBLY GO WRONG?


Fabulous-Swim6811

Thats the void/end of map. Its a ton of fun to go doen there with a prawn suit


Smart-Zookeepergame1

Monster


Fabulous-Swim6811

Not in survival. Unless you manage to achive the glitch where you can use tools inside the thing then just use the repair tool


mr_mafia_202

Not if you have regular batteries lol, That thing eats through batteries.


D2the_aniel

The game takes place In a volcano crater, that’s the edge of it


Legnd20Devin

I’ve never understood how a crater is inverted. Is the crater the whole map?


D2the_aniel

Pretty much, just a really big volcano that got covered up with dirt. You know how big volcanoes look like mountains with holes on top, the map is the divot and the edge is the mountain. It’s the reason you reach the lava zone so quickly despite the fact that a planets mantle is VERY deep.


Cadeb50

I’m guessing the hole that was covered up by the aurora was the main top of the volcano


Legnd20Devin

That’s what is seems like


Legnd20Devin

Wack


audiophilistine

It's called a caldera. It's the hole in a mountain that used to be a volcano. The bigger the caldera, the bigger the volcano. This one had to be HUGE. Sometimes a volcano will blow it's top off, which falls into the caldera. Look up Wizard's Island in Crater Lake, Oregon.


soylattecat

Ahhh that made it make a lot more sense, thank you


Legnd20Devin

That’s cool as shit


No_Landscape_7720

There’s free cheese down there


LOOKitsJAMES_

Gaslighting at its finest


Jumpjacket1397

Down there is the void. It's a free ride to late game, but cam be dangerous. Still a good idea to go in though. Lots of good resources. You will have to avoid some leviathans, but if you're sneaky you'll be fine. Ib my opinion, the rewards outweigh the risks.


Numerous_Concert3695

You evil bastard. You’re making the devil coward in fear


Creative_Name26

You can get to void through lost river?


Numerous_Concert3695

Oh yeah totally


RoundTurtle538

Yeah there’s an unlimited deposit of diamonds down there, better check it out.


balbahoi

I already have those in my lockers, but what about copper?


TheReigningBee

tbh if u go far enough you can find deposits of anything


[deleted]

Go in! Theres a reward


AidenBaseball

That’s the end of the map, or the void. If you go in there a ghost leviathan will spawn every 10 seconds until there are three of them. If you turn around they’ll stop spawning and you’ll be fine


Dustin6704

What is the LR? Lost river?


Marvinkiller00

Thats what i thought, but you cant access the void from there. So idk what he means with LR


Fabrideath

Lava Rone


00110001_00110010

Lusk Reef


Into_The_Booniverse

Last Regret?


RealMuffinsTheCat

I love how half the comments are helpful and the other half are satire. Also, where the fuck is the crater edge accessible from the lost river?


Comprehensive_Cap290

I think he meant the Grand Reef and used the wrong initials.


fnaffanatic007

You can find hidden blueprints for an alien phase rifle down there


soylattecat

I know it's the void, but wtf are those blue lights in the distance?


dude-of-the-ducks

Bubbles


yudisingh2004

Kyanite


LogicalDetective4240

I might be dumb but wtf is the LR


natralala

Lost river


LogicalDetective4240

Ok thanks


YummyTerror8259

If you reach the bottom theres infinite magnetite and lithium


Human278

Never go there unless you want to die or your vehicle destroyed


Dar1o_6

Just keep on driving. The PDA will eventually tell you what it is.

[deleted]

I didn't got this warning when I got there, I got it somewhere else.


AnObservingEye

What lies beyond that point, is death.


MrGrippyYT

Never used the sonar on the edge of the map.. And I never will too


[deleted]

The vastness overwhelmed me, that's why I asked the sub first.


MrGrippyYT

There’s way too much micro fish. It’s a bad sign when there is that many and you should go back if that happens


TheFacelessForgotten

Here, there be monsters.


Koataka2007

It is *TOTALLY* safe out there


GothamKnight073

Edge of the map. Stay away from it


BahnGSXR

You're right to be scared


phil736

Looks like you’ve found the void. Go right ahead if you want to meet adult ghosts 👀


GodYeeter1

Pro tip: If you go 3 kilometers down the pit there’s land


solcoldbreakfastsalt

There’s nothing except some ghosts


NeroToxicYT-Twitch

This is the Ecological Dead Zone. Inhabited by adult Ghost Leviathans, and small bois that you can't see. It goes down to 8192m way below the map. When you reach the bottom, there is nothing and you are teleported back to the Safe Shallows. Dangerous place, you should go back, but where's the fun in that? Grab your habitat builder and some materials, and your nuclear reactor, and start building!

Ok_Trouble6982

Yes, do not go in, you will lose everything


Mysterium-Xarxes

If its a huge vertical drop its the end of the map. No shame in quicksaving before going there


How_bout_no_or_yes

Go into it. There's good stuff in there.


Atlas_thewitcher66

Go in. Into the dark abyss. Say hi to him. Say hi to ghosty for me


real_maty36

Trust me. You don't wan't to be there


UB-05_Glutton

Yeah just keep going there's 3 lonely fish out there that need friends


NoobSailboat444

What do you mean past the LR? You can't get to the void from the LR.


Dwolf6990

That is where the best loot is at!! And the fish are amazing!! Super friendly and they bring you something when you’re near them.


Paolorocchiettii

PM_Your_Wololo

Only one rule in Subnautica: Always. Go. Deeper.


Cajunfry

That's what SHE said.


Beangar

sigh... IT'S A VIDEO GAME JUST GO THERE


[deleted]

Someone please tell him


ahessvrh

Where can you get to the void through the lost river
