The Celeste Speedrun That Does Nothing for 472 Hours

[@Peter_Cordes]

Right? As a programmer and CPU/assembly language optimization expert, just /facepalm and shaking my head. float for a timer? And one that the game checks for divisibility by 3 or something? n % 3 == 0 is vastly more efficient for integer than FP. (Well hopefully they just add something to calculate the next deadline so it's still just adding and comparing, not a modulo every frame.) What kind of language was this written in? Presumably not Javascript; JS numbers are double-precision floating point that can represent every integer up to 2^53 vs. single-precision being able to represent every integer up to 2^24 (with larger numbers rounded to nearest multiple of 2, then multiple of 4, etc.) So 1 ulp (unit in the last place of the mantissa) becomes larger than 1 at that point, and is where adding 1 with round-to-nearest will stop changing the value. IDK where the 2^19 comes from; perhaps it adds something larger than 1 every frame, like maybe it counts in milliseconds and it adds 30 ms or whatever. Wikipedia's article on single-precision floating-point is very good.

Celeste is rare for me in that I followed the game from the start, not realizing at its release how popular it'd be for speedrunning. So as such, despite not being a speedrunner, I had the unique opportunity to follow how strats developed and encourage as a fan and even friend to some streamers in their efforts to complete their runs and find new strategies. Despite all that, I had _no_ idea this insane minimum grabs run was a thing. Thanks for informing it!

This can take hundreds or sometimes thousands of years each time it is used and it is used each time the b button would otherwise have to be used to jump.

plot twist: the glitch was intentional and it was just the developer's way of saying "you've been here for 118 hours. i'll help you get through this as best i can, but *please* take a break"

there's no way this could be intentional; unless they're being really smart with floating point imprecision

Most likely an engine limitation or careless programming. There is no logical reason to store an integer number of frames in a float variable unless integer data types simply don't exist (like in JavaScript).

Because the variable is also used for a lot of visual stuff, and it has to account for different game speeds so they couldn't really make it a fixed integer amount.

​@@SSM24_ Nanoseconds, kiddo. Just store the number of nanoseconds in a 64 bit integer. That should be good for half a millennium.

[@Harrs2]

Decimals first off, and what practically is there to coding for a 100+ hour play session? Besides it being bad for your device's performance, basically nobody plays in a single session for that long. Allocating resources, and money, to fixing the float problem when it won't show up in normal play is the wrong move.

[@Imaginary_One]

@@Harrs2 You wouldn’t have to allocate money and resources lol it’s just using an int instead of a float. And if it’s performance you care about, operations on integers are way faster than floating point values.

[@LeMustache]

​@@Imaginary_One1. They'd have to put resources into this now to fix it, that's what they meant. 2. On modern x86 float operations are not slower than operations on integers. They're often faster because there are special versions of many instructions that let you perform operations on entire vectors and matrices at once. Floats being slow is a thing of the distant past on PCs.
