In Japan, it is called ケツワープ (butt warp) Edit: The way Mario's kinetic energy accumulates is similar to the シツリョウホゾンノホウソク(law of conservation of mass) in physics This is called ケツリョウホゾンノホウソク (law of conservation of ass)

It looks like another way to tell the difference between true staircases and slope staircases is the drop shadow. True staircases have a horizontal shadow and slope staircases have a shadow with the same angle as the slope.

You can also tell if a staircase is a staircase or a slope by looking at Mario's shadow The main foyer staircase will have Mario's shadow projected diagonally while literally all the orher staircases in the castle will keep Mario's shadow horizontal and attached to one step at a time

[@FrostbytesYT]

After all these years. I can understand the most insane glitch in SM64! THANK YOU ❤

[@eddievhfan1984]

I can't remember if it was on another video you did, but IIRC, Mario's collision is kinda raycasted, but rather than check for any and all intersections along his projected path, it just moves him a quarter-frame, tests his hitbox, and repeats the process for as long as no collisions are detected. At high LBJ speeds, the quarter-frame checks can't detect a collision, and let him just phase through.

[@Ragesauce]

I can't wait to play your fully optimized SM64 game on original hardware, I hope it releases soon!!

[@CottonModem]

It feels weird to hear the word "exponential" these days used to describe something that's actually exponential. Thanks for the explanation; I basically only knew about the uncapped negative speed part of it.

[@KazeN64]

LOL true that word gets misappropriated a lot I especially dont like it because like what if the exponent is less than 1?? now your exponential growth isn't even positive

9:08 Is there a reason why Nintendo would need to set the negative speed to zero, rather than simply limiting it? Is the issue only resolved if Mario can't go backwards at all?

Nope, had they just limited it to -15, itd look a lot less jarring and play better. There is no reason not to do it that way imo

[@Dwedit]

Surprisingly not a Pannenkoek video.

[@jlco]

"SM64 has no inertia in the physics" Based on Mario Maker... they still haven't quite gotten inertia right.

[@pleasedontwatchthese9593]

It is true that a lot of old games don't have real inertia, though typically old games like this mimicked inertia by just doing vector math on the velocity. Like its a natural outcome of that though its still fake because mass is left out but to the player it sometimes feel like stuff has weight to it. I typically make fake inertia by something like modifying the acceleration to make it seem like its heavy or light, like a heavy object takes a % of acceleration away. Even super mario bros on the nes had a concept of that. But I really dont know how mario 64 works for the player so they could be something something funky they do. In the code examples he gives there seems to be a lot of art than physics that Nintendo did.

[@jlco]

@@pleasedontwatchthese9593 It was in quotes because Kaze basically said it in the video; SM64 does not preserve momentum when jumping off of moving platforms. Super Mario Maker 1/2 do preserve momentum... often in ways that feel really wrong. Jumping off of a moving platform just a frame after landing can massively change your speed. Which of course can lead to some hilariously unpredictable platforming setups.

[@pleasedontwatchthese9593]

@jlco thank you for explaining that to me. What you said makes sense

[@tbtb66]

I always loved the tidbit of speed is not equal to distance in SM64 when referring to building up speed It's like the game is it's own little physics sim

makes me wonder so is the updated Shindou version have improved code? After they realized how messy it was? or did they just really hate people having fun?

[@Mr.Q_Dude]

​@@KazeN64 Every time someone explains the reason for BLJs not working, they say a cap was put on the negative speed. Now that we finally see how it works, I have a question. Was there a cap in place as a precaution, or were we just wrong about the Shindou Version the entire time?

[@DenniselAzul]

Thanks for explaining it very well! Now I understand how this works.

[@Dell2YT]

I have tried, unsuccessfully, to BLJ casually for years since I realized it was possible on early KZbin. I still haven't gotten the timing down but I'm sure I'll get it during a playthrough some day ✌️

[@PHR16384]

8:50 Amusingly, Unreal 4 has (almost) the same exact bug. Example: In the game SatisFactory, stacking Hypertube Launchers together lets you reach absurd speeds just like a BLJ -- each Launcher adds 20% to whatever speed you enter at. You can stop yourself with a solid wall at your destination, but if the wall is too close to the tube exit, or you're otherwise still flying too fast, you'll phase straight through. Don't know how such phase-through is possible unless it's coded just like SM64's collision detection... On the other hand, while you're inside the tube, you'll never get ejected prematurely no matter HOW fast you are (prob cuz the Hypertubes are spline objects, and surely programmed such that the player just snaps to the spline curve every tick)

[@DaNormalGuyathon]

quick correction: you cant actually blj on the staircase that connect the castle lobby and the basement because of the wall hitbox
