*Check the description for extra notes and details, and for the list of background music throughout the video.* There are subtitles provided, and also one (telegraphed and silent) jumpscare at 4:41. Any questions are welcome, but this video is the best general explanation I could create. *FAQ:* *Q:* _What's MB2/Mystery Box 2 Jack-O-Bonnie?_ *A:* Mystery Box 2 (MB2) is a move in FNaF World that swaps out your party members with 4 random ones. Scott made a slight miscalculation, and the maximum character number was 41, which didn't even exist when the game launched. It being so rare meant it never got patched, and after update v1.2 dropped, Jack-O-Bonnie became character #41. *Q:* _Why are the probabilities powers of 2?_ *A:* They're simplified fractions of 4/65536 and 2/65536; as the way it's setup, the probabilities of all the random stuff in Clickteam Fusion are out of 65536. They just happen to be powers of 2 though, they could've been 3/65536 or 10/65536. *Q:* _Did the Android glitch also affect iOS?_ *A:* No, it was exclusive to Android. You can actually verify this by trying to find old videos of Golden Freddy on Android vs. iOS. It's not that hard to find people finding it on iPhone, while every video on Android just shows the 1/9/8/7 Easter egg. *Q:* _Is that The Cure - Close To Me playing?_ *A:* Yeah? Kinda, it's a SiIvaGunner rip that uses the FFPS soundfont: kzread.info/dash/bejne/pGphtJSAcdbRh9I.html

I'm sorry, it only generates 16-bit integers??? That's incredible. I remember seeing the unreasonably high odds of some of the easter eggs and frankly being shocked that we still saw them in content creator playthroughs as often as we did. Guess that explains a lot. The Android bug stands out to me significantly, as well. When I documented all the old mobile ports, I did so using iOS figuring there wouldn't be any substantial differences other than the microtransactions. I did notice that it took me significantly longer to get Golden Freddy to show up in FNaF 1's old port, but I just attributed that to possibly being because of faster nights, or just from bad luck. Because of that, I never believed any of the claims that Golden Freddy didn't exist on Android for a single second, since, y'know...everyone was really eager to guess randomly back then. Thank goodness we don't do that now, huh? Imagine if everyone guessed at something big like, for example, Fire Escape Ending requirements! Great video as always, and thanks for setting the record straight! (Also, using the negative overflow bug in FFPS to help explain the concept was honestly really slick. I need to start taking notes from your content it seems, lol)

You would have been right to use either port for any of the games after FNaF1, as they use the exact same MFA, just using different Clickteam exporters. But hold on, when did you document the old mobile ports 😅 Anyway, I tried to make the video mirror my own process of figuring out the why and how of it all.

Absolutely love the "you could use char, but... please don't" note at 7:38. For context, char (short for "character" as you might guess) as a data format is an unsigned 16-bit data type which *can* technically be used to store numbers, but what it's *actually* intended for is storing *text,* or more specifically individual letters, as the name implies. Programming languages tend to treat textual data types very differently from numerical ones, so actually *using* a type like "char" for storing numbers would require some type-conversion gymnastics, hence the "please don't". (It's interesting to point out regarding this subject that Java actually doesn't support unsigned *anything* for numbers. Every numerical data type is signed!)

@@itztaken wow thanks for that! Man this was a massive learning experience lmao. I first heard of overflow glitches because of Pokemon RBY's EXP overflow glitch with level 1 Pokemon in the Medium Fast EXP Group (you normally can't get level 1 Pokemon in RBY, but glitches lmao.). If a level 1 Pokemon in that EXP group gained less then (I think it was) 64 or 63, it'd overflow and level the Pokemon up to level 100 instantly

this is kind of just a guess, but the reason that the games are capped to 16-bit numbers MIGHT be related to how Clickteam originated from a VERY, VERY OLD LINEAGE of game creator software, all the way back to Klik & Play. Klik & Play was literally built to run on *Windows 3.x*, which was indeed 16-bit! given that the underlying engine hasn't really been updated TOO much nowadays (clickteam has been surprisingly keen on backwards compatibility with project files), it makes sense that the standard variables are still in 16-bit.

@itztaken

5 ай бұрын

That does seem to be potentially why, as the limitation dates back to at least 2006, though the implementation does use 32-bit integers. Overall, I don't see why the RNG wasn't updated to 32-bit in the decades since, as the only way that'd break backwards compatibility is if the program relied on undefined behaviour.

This reminds me of the nuclear Gandhi glitch from the Civilization series. In one of the earlier games, the exact same negative number glitch happened, and when the programming generated a similarly massive number, Gandhi always went nuclear despite his commitment to peace. It’s become such a meme now that even in later games that avoided the glitch, the team still references “Nuclear Gandhi.” Civ 6 even gives him an 80% chance of having the secret agenda “Nuke Happy,” where the AI seeks to develop nuclear weapons and likes/dislikes others who do/don’t

Honestly without Markiplier's encounter, I think genuinely FNAF as a whole wouldn't have taken off so hard.

My brain didn't immediately make the leap to "every random number in all Fnaf games is an unsigned short as well" so you might have wanted to mention that when transitioning from pizza simulator to golden freddy. But awesome video still! I love learning video game math.

Here's another fun fact: There's actually terms for this exact type of bug. We call them interger underflow and interger overflow respectively.

@5:50 65535 MOD 100 = 35, so in this case, a shorten RNG range will have an output of 0-35 occurring more often than 35-100. Range 0-35 will each integer be 1/656 chance while 36-100 will each integer be 1/655 chance. Calculated by dividing 65535 by 100, which gives out 655.35, or 655 remainder 35. We have 655 complete ranges of 100-size, with an incomplete range size of 36. Because Modulo outputs a number strictly lower than the denominator, the numbers in the lower part of the range happens more often.

Integer underflow causes so many cool glitches
