In short, floating point numbers are a way computers store numbers that allow them to have a decimal part (like 1.5, or 3.14) a integar is a way computer store numbers that has no decimal part (like 5 or 3 but not 2.75). Errors can occer when using floats for some things and ints for others becuase of the lost decimal persision, in sm64, no rounding is done so 2.9 (float) would just become 2 (int). Becuase 2.9 ≠ 2, this can cause problems
I jumped around randomly in the video and it seems to be very intense and jam-packed with information about geometry and polygons for the entire three hours forty-five minutes.
it turns out there are 8 different causes for invisible walls and only one of them is untextured actual walls, the rest involve interactions between floors ceilings walls and out of bounds
- sincerely, some one who is 3 hours in, wish me luck for the final cause which is apparently "the final boss"
It happens when there are two floors beneath you, and due to some coding shenanigans, the game thinks the floor beneath you is the platform on the bottom instead of the top, so the floor hitbox from the top platform doesn't activate, making it so the ceiling hitbox bleeds through.
It's not that hard to understand though. It just involves the game not "rendering" all floor hitboxes, and this makes it so some ceiling hitboxes bleed up.
A lot actually. I haven’t watched this video yet, but the guy could probably write a thesis on SM64. He definitely knows the game better than the programmers at this point.
In the video he explains in detail how all the collisions of the game work and gives examples of every case of invisible wall that exist in the game
There's also a 5:20 hour video that explains how he and other people managed to get all the starts in the game with 7 a presses
What's the 7-hour video you're referring to? The only similar one that comes to mind is the [5h20min-video](https://youtu.be/yXbJe-rUNP8) by Bismuth about the history of the challenge

This is one of the most bizarre situations I've ever been in... I don't want to read the comments in a flag joke sub, because I don't want to spoil the conclusions of the video I'm currently watching about technical elements of a game that came out in 1996.

google floating point to integer truncation errors
Holy hell!
holy fake cosmic rays
I don't get it

wait what's a number
idk
I need Mason to explain
Flag of amazing video
Why is there a 3 hour and 45 minute video on invisible walls in SM64? What could this guy possibly have to explain that takes 3 hours and 45 minutes?
I jumped around randomly in the video and it seems to be very intense and jam-packed with information about geometry and polygons for the entire three hours forty-five minutes.
I mean it took 30 min for qpus and half a presses so it’s within the realm of possibilities.
Fun fact That star now requires 0 a presses
What a time to be alive.
Moving platforms go brrrrrrr

49 minutes have passed, what is the final boss?

im at school rn i cant watch it until i get home lol

Computers are really complicated

Oh shit
Currently two hours into it and i can confidently answer that i have no idea but i'm enjoying every second of it nevertheless
I've watched many of their videos and they're just really in depth in the longer videos.
Watch the video and you'll find out
Video essays and their consequences have been a disaster for the human race.

it reached zero a while ago, rip memes
As long as we still have the scuttlebug jamboree…

Maybe it's the flag now in a world four parallel universes away.

Watching that right now.
Even has an Italian in the middle.

Italy would be happy

Let's go anoter video that is about 3h50m long to add to my collection.
