The MONSTER MATH behind Ninjabrain Bot

Your mathmagician here. This video requires math knowledge. I hope I made it clear and understandable. And I hope I wasn't talking to fast. Understanding the math in ninjabrain's bot took me many hours and this video has 9 minutes, so the probability of YOU still having some questions after watching is quite high. Fortunately I read every comment (even when people write entire essays in the comment). Also show this to anyone who thinks math is useless. I mean, how do you even play Minecraft without knowing how to calculate integrals? Throw more than 1 eye of ender? Nah, just do some basic calculations.

[@sharpieman2035]

At 3:25, it is not that the stronghold has to spawn under a single biome. It is that only certain biomes are considered as valid to be spawned in. If the stronghold generation is in an invalid biome, it will attempt to select a different chunk within a square of the location. If it fails, it says in the same spot. This changes the distributions of strongholds slightly, I think the paper explains the impact on distribution this has.

[@Antifrost]

I'm not particularly interested in Minecraft speedruns anymore, but the math involved in the strategies and tools used are certainly interesting. I do wonder how detailed these tools can get before it crosses the line and is considered cheating, though I'm assuming that the argument is that as long as the game itself isn't modified and you're only using data provided in-game.

[@HeppeGaming]

Calculators used to be banned in speedruns. Only I think 3 years ago they got unbanned. But at the end of the day, it's just a calculator. A human could do the math himself, but it would take a lot longer

[@Mcwarden-c6z]

In bedrock edition you don't need ender eyes because 80% villages have strongholds

[@Doogie8876]

I think I am wrong but here is a more simple way of explaining it. Basically when the calculator gets your co ordinates and exact angle it finds an area in the direction that is on the specific chunk co ordinates that eyes of ender go down in. Then it will tell the player where the 4-4 co ordinates in the chunk are. I definitely butchered that and might be wrong but I think it works similar to that. Correct me if im wrong tho, I am bad at math

[@dragskcinnay3184]

Thank you for explaining calculators work. Couriway doesn't use them, so it didn't really need the info, but thanks anyway

[@fire__ferret]

‏‪3:59‬‏ aren't they called cartesian coordinates?

[@animowany111]

Cartesian and rectangular coordinates are synonyms.

[@Fantastish29]

So if I understand everything right, we use the boat to take a precise trajectory of the pearl, then look if the trajectory crosses any chunk origins within the stronghold spawn circle. Why do we need to mess with probabilities in that case? To remove the fringe cases where it crosses other chunks' origins?

[@HeppeGaming]

Because we're dealing with uncertainty. If you slightly missalign your crosshair to the eye, the correct chunk will also appear in the table of the calculator, just with a smaller probability. And even if you align the crosshair pixel perfect, there is still a little uncertainty, because Minecraft is just a game, so there are limited amounts of angles that you can face.

What does the boat do?

[@Myk-oy8tq]

It resyncs the players coordinates with the server so that there is less deviation from your client position and server position (Your computer runs a server on your computer that only you can connect to)

[@HeppeGaming]

Basically, it increases accuracy by using a much better measurement technique

[@M_1024]

@@Myk-oy8tq thanks

[@sirvyving5047]

If this were the case, the boat angle would be irrelevant and only the 'boat postion' would be neccecary. The boat is used to snap the players facing direction to one of many 'minecraft determined' angles which a boat is able to face, these angels are known to basically intger precision as is the player's mouse sensitivity allowing ninbot to add/subtract integer multiples of your sensitivity to your boat angle transferring the accuracy of the boat angle to the eye measurement. Server side de-sync can be an issue but as far as I know there is no way to prevent it in a run and runners normally just take the L when this happens.

[@gus9351]

​@@sirvyving5047 Server side desync is preventable in many ways, and yes exiting a boat does in fact prevent it, but it's only one of the many ways you can do it. There's a great video about it by Char, should be the first thing that pops up if you search "ender eye desync guide"

[@vegegrey1709]

4:50 im not sure this is relavent to calculating the position of one stronghold. This fact is only useful to find other strongholds in a ring where u alr know the location of one of them. Also 6:18 in 1.16 the eye doesn't point to the chunk origin it points to the center (8.5, 8.5) therefore the line should have to satisfy the parameters of 8.5 = x mod 16 and 8.5 = y mod 16 (with x and y being the coordinates of the stronghold) but for some reason ninjabrain bot doesnt calculate it like that. I once asked my discrete math professor this question and he solved it theoretically using the extended Euclidean algorithm which computes the integer values of s and t, a(s) + b(t) = GCD(a, b) Any idea how he did it?

[@kostya48i57]

Answering you second question, it is not that difficult, assuming you have the equation of a pearl line You can describe it as Ax + By = C Therefore you can assume that y = (C - Ax)/B, under general assumptions Then you have system of equations like 17 = x mod 32 17 = (C - Ax) / B mod 32 Rewrite x = 32k.+ 17 then you have 17 = (C - A(32k + 17)) / B mod 32 Solve this for K, now you have your points, though it is not completly true, you need to take in account floating precision. Modular arithmetics and CRT or Euclidian doesn't work well under real numbers, because it is hard to define GCD. The better way of doing this, is to divide each chunk into 4 equal subchunks, and you can use the default algorithm.

So, teacher, can you do an example by hand just so I know FOR SURE how it works? After all, it does need to be theoretically calculatable by hand to be allowed in a competitive minecraft speedrun, right? Otherwise it would fall more into tool-assisted?

Sure, let me just write down 10 000 integrals for every chunk on the nearby ring and solve them
