Summary

An LCG random number generator that resembles the behavior of java.util.Random. This means the randomInt() method of this generator will generate the same number sequence as java.util.Random.nextInt() when both are initialized with the same seed.

The purpose of this package is to provide a random number generator that can be initialized with seeds as to create reproducible random number sequences, because JS Math.random() does not provide such a feature.

Usage Example

import { Random } from "@kobayami/random";

const WIDTH = 640;
const HEIGHT = 480;

const rand = new Random(1923968746);

function getRandomPixelPosition(): {x: number; y: number} {
    return {
        x: rand.randomInt(WIDTH),
        y: rand.randomInt(HEIGHT)
    }
}
