in javascript you can't seed Math.random, if you want something you can seed you have to implement a PRNG yourself
i needed a function that returned a "random" value in [0, 1), like Math.random does, but seedable. importantly, it wasn't for anything even slightly cryptographic or whatever. i had absolutely no requirements for the quality of the output beyond "seems vaguely random to a person"
so here's the simplest, and probably worst (but good enough) PRNG function i found online:
let seed = WHATEVER_NUMBER;
function random() {
const x = seed++/Math.PI;
return x - Math.floor(x);
}
@wallhackio report me you won't
@monorail guess again fucker
@wallhackio do you like my javascript
@monorail it disgusts me
@monorail also, reported a second time for using a function declaration
@wallhackio oh yeah are you supposed to do const random () => {}; now or
@monorail @wallhackio i won’t say “supposed” (function hoisting can be nice fur readability; openbsd c style is to do the equivalent and start with main()) but it’s very common
