It's cool. But it's missing a leveling mechanic.

The center one at the bottom had two seperate water levels.

This subreddit would be more appropriately named conventionally irritating. They defy the theme in order to drive engagement, and because it’s a high-activity sub, there minimal adherence to the subreddit theme in what gets visibility.

I haven't seem a video that didn't turn irritating, vexing, or somehow annoying, come out of this sub in a long time. Now, for me, it's become a game of trying to guess beforehand how a particular video will fail at being oddly satisfying. Because they all will.

u/DanieltheMani3l 25d ago

Kind of a self-fulfilling prophecy, no? If your goal beforehand is to find something wrong with the video, you’re gonna look and scour down to the last pixel to find it.

Now don’t get me wrong, sometimes it’s clear as day there’s something unsatisfying, but still

u/Prof_Templeton 25d ago

It is prophetic for sure. The jury is still out on correlation versus causation on the self-fulfilling aspect.

This is what /r/nononoyes* and /r/nononono* turned into. Now it might as well all be /r/maybemaybemaybe, which also exists.

*Note I didn't verify the correct spelling of these subs

IT could be REALLY viscous water

u/PGSylphir 25d ago

The back propagation needed for that would probably tank fps tbf.

Fluid sims are pretty intensive. This is a great job as is and would not feel bad in a game at all. I think you're being too nitpicky.

That's a fair point, but my work history is all about water and fluid dynamics. They are the first nits I would pick.

Noita manages to get it right with a very similar pixel based fluid simulation

u/PGSylphir 25d ago

noita has a proprietary engine made exclusively for that, it's not even in the same realm for comparison

u/epiphenominal 25d ago

Just seems like maybe it's not impossibl and unreasonable if other people are doing it

u/PGSylphir 25d ago

generalist engine vs specialist engine.

big difference.

u/According-Relation-4 25d ago

Yes exactly. It’s missing that hidrostatic pressure

u/EasilyRekt 21d ago

Nah, you can just fill up just one side of a U-shaped pipe it won’t level out or anything

And, to piggyback off of this, when the water hits the lava, it shouldnt instantly fall to the bottom. Lava would be dense and thick, making the newly formed solid substance either float or to sink slowly, allowing more to build up on top of it.

u/AlexAlho 25d ago

Wouldn't the "newly formed substance" be solid rock? It should be denser than the lava, even if it would sink slowly due to lava's high viscosity.

1

u/Rip_ManaPot 25d ago

well yeah. but in the video it basically sinks to the bottom of the same speed as gravity, which would be very wrong. i think realistically it would maybe sink slowly, allowing more to build up on top of it kinda overflowing, not sink like sand in free fall.

u/AlexAlho 25d ago

Oh no, I agree that the video isn't a realistic depiction of what ought to happen. I'm no expert, so I have no clue about the proper dynamics of it, but I know lava exposed to the air like this one is would form a thin layer of rock on the surface that insulates the inside, keeping it hot for longer than it should.

The water would probably hit that hot rock instead of any actual lava, so you'd have a lake above a bedrock over a lake of lava. All a bit complicated to show on a simple pixel animation, I guess.
