Yes, it is an actual thing that affects fishing… slightly

Terraria’s most obscure game mechanic – air pressure
50 Comments
Note 1: Air *is a fluid*. A fluid is “a substance, *as a liquid or gas*, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape” (dictionary.com). It’s a broad term.
Note 2: use the desmos if you want to explore for yourself. Your values will vary from mine by quite a bit!
Also, to get the surface value you need Tedit. Due to out of bounds stuff you can’t just fly up to space and check
I have 3,000 hours in this game, I’ve gotten the 200 Fishing Quests achievement, and I did not know this mechanic existed!
Water pressure:
Clicked on the video thinking you were gonna tell me something I already know about the weird way in which air seems to exert way more pressure than water does when it comes to how water flows and how water absolutely refuses to flow upwards, not even the tiniest bit, even if there are thousands of gallons of water pushing it through a narrow tube with a tiny opening at the bottom. Was pleasantly surprised what the video was actually about.
EDIT: Also I've seen some pretty small sky islands that were only like 5×40 blocks of water which would only be about 200. Thankfully, they all work partly thanks to this mechanic.
Trying to figure out where the air pressure factors in. It just seems like altitude to me.
Yeah uh, cool but a modified height value=/=actual air pressure, its just flavor text to fix fishing on sky islands. 🤡
My theory is that it's part of a joke on fishing; I think one of the goals of the devs were to make fishing in terraria as complicated and unnecessarily complex as possible.
The amount of needed water, time of the day, phases of the moon, bait used, rod used, equipment used, potions used, luck factor, altitude, block placement, air pressure, biome, chum bucket decay… All of these are factors for fishing. It could be as simple as biome, rod and bait lol
Yes, pump those useless game facts into my veins. I can never get enough
Never heared of this, but I also never fish^^
Honestly I subscribed on "I have a desmos link in the description"
Ah, weird complicated mechanics that only affect a small protion of the game
Classic Terraria
Modern terraria updates are adding in more and more seemingly pointless features that most players appreciate eventually, things like gembunnies that are functionally useless but look pretty, or the princess NPC.
I'm guessing when they were adding fishing, they spitballed every possible factor that could impact it and just added most of them to the game. Air pressure was probably programmed as a mechanic, half-implemented (hence its almost functionally useless impact) and then never expanded.
How to fish in Terraia everywhere: use an hidraulic press to get H2O @ 376 atmo, and you will be able to fish direcly from the palm of your hand (if you manage to prevent the pressure bursting the now solid cube)
I don't know the most well known Terraria mechanics but I do know about air pressure now
what a cheap made video.
boring
and streched out for no reason
pretty sure this is just so that using natural sky island lakes actually lets you catch fish at normal rates
wait so wtf is air is air just oxygen or is air just the stuff that isnt filled in by physical objects so can you have oxygenless air? what is air guys
Maybe the fish are stupider because they're not getting enough ocygen
This was likely implemented for sky island fishing. If you had to create a sky lake because your world didn't have a floating lake, it would suck to cart up 300 buckets of water without a bottomless bucket.
While this was probably implemented for simple mechanical reasons… pressure DOES have a huge effect on the behavior of water. Essentially, what keeps all water from spontaneously boiling off is the vapor pressure. Water molecules at the surface of a container spontaneously evaporate/boil and with a higher vapor pressure, most of these molecules have the tendency to condense and fall back into the liquid state. Some inevitably escape, hence why water evaporates even at room temperature. With low enough vapor pressure, the water will lose molecules more quickly. Eventually, the vapor pressure is equal to the atmospheric pressure, and gas can spontaneously form below the surface. We can lower the vapor pressure by either heating the water or by reducing the ambient pressure.
If you boil water at sea level, it may take 5 minutes. If you boil the same amount of water on top of Pike's Peak, it will only take 3, and on top of Everest, it takes a minute.
Air is a fluid? Great video just got confused at the start
> air exists
[citation needed]
Anyone who thinks air is not a fluid can fight me… Or just pick up a dictionary/take a basic science course.
What a bizarre thing to implement in such a limited fashion. It has no other effects? It isn't affected by time, weather, heat?
0:02 Dude, air is a gas xd
You sound like minute physics
air is actualy a gas,but i do see the notes on the pinned comment
Not a player, but I got a weird theory:
Maybe affecting fishing in high altitude is just a side-effect?
Maybe the intend was to stop you from fishing deep underground since it is based on height, and nobody ever fixed it because it is just fishing anyways?
I figured it had air pressure given how water doesn’t fill upside-down caves underwater, but I had no clue about the fishing thing.
i think they added this for the sake of the fishing quests, there's not much water on the floating islands it would be too hard to get the fish, there's a lot of water underground so it would be too easy.
I have no idea if I have been clickbaited or not. This sounds so ridiculous that there should be no reason for it to be in the game. But I also dont fish with exactly enough water….normally it is significantly more than was ever needed because lol water duplication go brrrr
@Terrasteel does Atmo work on other liquids? Asking for a friend.
What if they added water pressure which damages you the deeper you go in the ocean? Would be a disaster tbh
I love fishing idc what anyone says
mfs when they realize that fluids arent limited to just liquids
It actually has to do with the fishes ability to sense atmospheric pressure. Rising pressure sends fish moving around cover and in lower depths, before the pressure tops out and fish become lethargic.
My guess is that it's this way so that if you want a fishing pond in a space base it doesn't have to be massive and vibe breaking or some shit
Literally nothing about this has anything to do with air pressure…
errrrrrrmmmmm its a gas just because something fits one definition doesn't mean its classified in all of them
Liquefied air is produced cryogenically, at -196°C. Pretty sure it's a gas when it's not a liquid, and there was no context for you referring to a liquid. You made a goof, don't hide behind semantics. Just have a laugh and move on.
I think the reason for this is sky lakes since I’ve seen some that generate pretty small and I don’t think that they want new players needing to make a whole fishing spot for quest fish because their sky lake is too small
This will affect the trout population
0:02 WAIT AIR IS A FLUID OH SHIT I THINK I GOT 0 POINTS ON MY PHYSICS EXAM
Red on his way to add the most complex and realistic mechanics for it to only affect fishing:
2:02 A negative 75% reduction is a 75% increase… Why not just say a 75% increase instead?
Tell me what you want, but as far as my experience goes, fishes DO have sense of pressure and it can realy depend if the fish take or not.
Yeah… I never thought that would exist in terraria…..
Why the completely useless intro though?
"It is the most obscure yet"
<this video comes out>
It stopped being obscure (everyone knows it now) XD
One more reason for me to hate fishing.
