I Went to the Noita Far Lands...

I travelled through over 500 parallel worlds in order to test the limits of Noita's world generation. Here is what I found.

ABOUT THE GAME
===================

Noita is a magical action roguelite set in a world where every pixel is physically simulated. Fight, explore, melt, burn, freeze and evaporate your way through the procedurally generated world using spells you've created yourself. Explore a variety of environments ranging from coal mines to freezing wastelands while delving deeper in search for unknown mysteries.

I would have loved to see the gold room in these parallel wordls, because they tend to get more and more distorted with every parallel world, imagine what a W512 gold room would look like

[darkener]

They need to put an easter egg in the 511th world now, as its the last stable one. It would be interesting to see an npc or just some text talking about parallel world travel and telling you not to continue.

Imagine not finding circle of vigour in any and every one of these 1024 parallel worlds, that must be hilarious

~1 Week Later~
Noita update -> +[Cough] more parallel worlds added.

[CopiHuman]

This is super interesting! Thanks for sharing, I had a feeling there might be a more hard limit somewhere less then 2^10 worlds out due to limits similar to minecraft's farlands

I had some fun parallel world instability recently on a very long run I did. Turns out if your computer isn't quite good enough, you can get stuck in a fun cycle when teleporting into an area that contains objects with physics where the game continues trying to generate those objects until you either leave the area and come back, or crash. Basically turned every square inch of hanging vines into a rapidly growing mass of vegetation that does not enjoy being rendered.

Part of me is saddened that I’ve spoiled myself on loads of stuff, but at the same time I enjoy these videos so much and I’d probably never learn most of this anyway


Also that travel wand is INCREDIBLE. Love this game and it’s mechanics so much. Man I need to play it more

[dottedboxguy]

i just noticed that but the eyes on the starting pillar at 7:55 are switching on and off, i wonder if it's just a glitch or if it's normal or of it's some kind of secret

ah, good old floating point numbers.
the larger the interger part the smaller the fractional part. basically meaning: every power of 2 you move away from 0, they loose half of their precision.
which, if you're far away from 0 causes jerky movement of the camera/player/particles, stretched effects, and similar phenomenon.
they all could easily be solved by replacing the floats with fixed point numbers, at the expensive of some extra memory and CPU time.

Gotta love Noita, even the way the world breaks down has style! Great vid Fury!

i suspect I understand the limit at 512...
Each pixel is 8 bits of material data.
Each chunk is 1024 pixels wide (10 bits)
Each world is 32 chunks wide (5 bits)
That leaves 9 bits in an 32-bit unsigned integer... exactly enough for 512 worlds, from world 0 to world 511.

Spell effects require floating point calculations, so they will start to get inaccurate way before that if you don't use a local reference frame, hence the vertical lines.

I really like the effects as you approach world's end. Reality starts to stretch vertically and things begin to shake and stutter. I like to imagine it's like your reality is becoming more unstable and distorted as you approach it's border, sort of like approaching lightspeed or entering a black hole in real life

[bobloop]

fun fact well idk about fact but from what i know most games if not all have a type of far lands where the game breaks eg risk of rain 2 theres a video of someone going out of bounds and the character begins to stretch and glitch, a flash game i played i remember getting out of bounds and going so far my model began to stretch and morph. im not sure how it works but its probs something to do with continuously updating environments mabye not sure. The crashing also might be caused by an integer limit.

"But first we need to talk about parallel universes"

I just got Watch For Rolling Rocks flashbacks

[good-sofa]

I was thinking about how far can it truly go!!

[felixfelicitus]

The casual acid/slime rain B-roll was a nice touch

[bobsterss]

Fury begins talking about breaking worlds near the end:
World: *_Rains Worm Blood_*

[sinnison]

Why am I only just noticing the eyes changing on the stone on the left, starting at 7:36? Has it always done this? Maybe I just haven't spent long enough at the start to notice it?

"I would love to be able to breach this invisible wall"
In all likleyhood it's a built-in limit of the game, or rather the game cannot create a world beyond the 512'th because of the fundamental workings of either the engine, or even the perating system. 512 is a power of 2, and if something breaks when things are uncapped, it's usually at a power of 2. 512 would be 2^9, so the world storage is either a 10-bit signed or 9-bit unsignes storage. The particles going weird at 256 would tell me that it's probably a 9-bit signed that either underflows or somehow turns unsigned when a 257'th world is generated. Frankly I do not know why it works exactly like that, but I know that the barrier isn't something that can be overcome unless the engine gets reworked. At that point you are most likley writing to un-allocated addresses and screwing with things that shouldn't be messed with. The constant crashes beyond that point is a sign of that.
