TOOSOON Pseudo-Random Number Generator (PRNG) — Controllers

This project provides a PRNG functions with a set of Controllers for generating and manipulating pseudo-random values using a seed-based approach and various algorithms.

It adds additionnal features to the main library: toosoon-prng.

Installation

Yarn:

$ yarn add toosoon-prng-controllers

NPM:

$ npm install toosoon-prng-controllers

Usage

import { IntController, IntGroupController } from 'toosoon-prng-controllers';

const config = {
  count: new IntController('count', 0, 10),
  counts: new IntGroupController('counts', 5, 10)
};

console.log(config.count.getValue()); // Pseudo-random integer in the interval [0, 10]

for (let i = 0; i < 5; i++) {
  console.log(config.counts.getValueAt(i)); // Pseudo-random integers in the interval [5, 10]
}

Controllers

BooleanController

Generate pseudo-random boolean value.

class BooleanController(seed: string | number, probability?: number);

SignController

Generate pseudo-random sign value (-1 or 1).

class SignController(seed: string | number, probability?: number);

FloatController

Generate pseudo-random floating-point number within a specified range.

class FloatController(seed: string | number, min?: number, max?: number);

IntController

Generate pseudo-random integer number within a specified range.

class IntController(seed: string | number, min: number, max: number);

HexColorController

Generates pseudo-random hexadecimal color.

class HexColorController(seed: string);

ItemController

Pick a pseudo-random item from a given array.

class ItemController<T>(seed: string | number, items: T[]);

ObjectPropertyController

Pick a pseudo-random property value from a given object.

class ObjectPropertyController<T>(seed: string | number, object: Record<string, T>);

WeightsController

Select a pseudo-random index from an array of weighted items.

class WeightsController<T>(seed: string | number, items: Array<{ weight: number; value: T }>);

GaussianController

Generate a pseudo-random number fitting a Gaussian (normal) distribution.

class GaussianController(seed: string | number, mean?: number, spread?: number);

Group Controllers

Group Controllers manage multiple instances of individual controllers.

BooleanGroupController

Manage multiple BooleanController.
