The pseudo-RNG games use wouldn't actually allow the rolls to go on indefinitely, I have no idea what the recurrence time is but the C# random's state is 2^1728 bits so if it's possible to roll an item it'll definitely roll at least once in 2^1728 rolls as a very loose upper limit - that's still kind of a lot lmao

@eggyolk6735 10 ай бұрын

Yeah that's what I was thinking of too! the theoretical maximum isn't set by Terraria but by the psuedorandom function it's using instead. Maybe if someone knows what C# uses for random they can compute the seed that gives a theoretically longest chain of fails Terraria can go through when doing merchant slots.

@duncathan_salt 10 ай бұрын

This is only true if no other events influence the state of the pRNG. If other random events share the same pRNG, it's perfectly possible to manipulate it such that any states which would give a successful roll are avoided by ensuring those states are used by other random events. Ofc, idk if that holds true for this specific instance, just speaking generally.

For additional context, the upper limit of a C++ "double precision" floating point (and probably the same for C#, I'm not that familiar with it) is about 1.79e308 That's around 2^1024 I think, so this is getting into even more absurd magnitudes than what most programs can usually roll with

@jameswise9171 10 ай бұрын

But can the RNG function output *every* number? Sure, if it's output space is smaller than the state space then it probably does But it doesn't guarantee anything

The actual number you're talking about here isn't "infinite", but rather Omega. It is a finite number, meaning it's smaller than infinite, as whatever number of rerolls you choose you'll get a finite number, but it's greater than any real number as for whatever x number of rerolls with y probability there is the possibility of choosing x+1 number of rerolls with a y' 1 so it's not a probability, but everyone get the point and replacing infinite but "1/infinite" (not defined but whatever) or lim x->0+ of x is the same) There's a great video on infinite chess about mate-in-Omega move which talks in greater details/with a better explanation of Omega if you're interested, but feel to not care I'm just nitpicking at this point lol

@lefthandedscout9923 10 ай бұрын

Because of things like this, I feel like the more interesting question would be "what is the rarest possible OBSERVABLE Terraria event?" Like, when you see the companion cube in slot 1, you don't know how it got there. It might've rerolled like 19 times and had a probability in the millions, but it also could've rolled first time. Same goes with ladybug luck - you don't notice when luck triggers for a reroll but then fails the reroll, so I wouldn't count that either. I feel like under this logic, a pirate dropping a "lootsplosion" of all his items under the worst luck possible is likely going to be the least likely event, but it might be possible to find a rarer event in world generation - something like encountering a row of 20 heart crystals in a line in a cave or something.

@Mathemusician3141 10 ай бұрын

You can always make an "event" rarer by adding extra criteria. For example, the pirate had to be a pirate gunner, and it had to be killed at 74% completion of the event, and it... You can keep adding criteria. Of course, that kills the point of it, so I suppose it is "rarest event that is interesting", so it is more of a subjective thing. As for the 20 heart crystals, according to a quick google search (I didn't want to do the maths, I've done enough of that in this comment section today) there are 120 billion world seeds, so it is incredibly unlikely that such a seed even exists.

I have no idea how its actually written, but I'd assume for something like that, were it a problem, the game could just call a new process to determine inventory and spawn the merchant when that process returns.

@invalid_user_handle 10 ай бұрын

The problem with the chance being 'infinite' is that any pseudo-random number generator will eventually start to repeat it's values. Of course, any well-desiged pRNG will have a *very* high reoccourance ratio, so while it might take a couple years' worth of processing time, eventually, the RNG will produce a value that succeeds one of the conditions and eventually, one day, the merchant will find out what his inventory will contain.

@Mathemusician3141 10 ай бұрын

But if it repeats, it will never finish the rerolls. Because if you need the number 4, and your pRNG repeats after five numbers, and you get [3, 7, 1, 6, 7], you will never get the 4. This means that if the pRNG reaches its reoccurance point without having chosen an item, it will go on infinitely. Conversely, a RNG always has the possibility to select one, no matter how far through the process it is. If RNGs are like rolling a die, then pRNGs are rolling a die without dots and writing them on when you get a result. Also sorry if my terminology is slightly off, I'm but no means a statistician!

I feel like that part of the reroll code should have a chance increasing variable that makes things more likely to be chosen, thus, with each unsuccesfull reroll of the whole pool of items, the next rerolls have lower chances to fail, up to a point it is guaranteed to choose an item at some point

Hey Terrasteel-I think you might need to rework your "How strong is the Terrarian" question assuming one fallen star is one solar mass, unless Relogic has confirmed fallen stars as not being one solar mass.

@Mathemusician3141 10 ай бұрын

Well I don't know if volume scales linearly with mass when it comes to stars - bigger stars have heavier elements for example, but the amount of said elements could be so small that it is negligible - but if you assume that it does: A single fallen star is roughly 2ft by 2ft, as its points fit into to make almost a perfect square. (To check yourself, throw one on the ground and get out the ruler tool. You'll notice that the points fill the gaps fairly nicely.) So if the star has a radius of 1ft (2ft diameter) you get: V = (4pi*r^2)/3 V = (4pi*1)/3 V ≈ 12.57/3 V ≈ 4.18ft^3 (cubic feet) 4.18ft^3 ≈ 0.118m^3 (cubic metres) Our star, which is one solar mass, has a volume of roughly 1.4e27m^3, which is 1.19e28 times the volume of a single fallen star. If mass to volume scales linearly in this case, then we can divide the mass of the sun (1.989e30) by 1.19e28, and get 1.989e30kg/1.19e28 = 167.14kg So a fallen star weighs about 167.14kg. This of course uses lots of rounding, and approximate figures, however this gives a sense of roughly how much it is. (the fallen star would probably also have to be remarkably hot for nuclear fusion to occur on such a small scale)
