Class PRNG

constructor

• new PRNG(): PRNG

• Returns PRNG

Static _seed

Static seed

• set seed(value): void

• Sets the seed value for the Pseudorandom Number Generator (PRNG). If the value is undefined, the current timestamp is used as the seed.

  Parameters

  • value: string | number

    The value to use for seeding.

  Returns void

Static gaussianRandom

• gaussianRandom(): number

• Generate a random number with a Gaussian distribution.

  Returns number

  A random number with a Gaussian distribution.

Static hash

• hash(value): number

• Hashes the input value for use in seeding.

  Parameters

  • value: string | number

    The input value to be hashed.

  Returns number

  The hashed value.

Static next

• next(): number

• Generates the next pseudo-random number in the sequence.

  Returns number

  The next pseudo-random number (float) in the sequence.

Static normalizedRandom

• normalizedRandom(minValue, maxValue): number

• Generate a normalized random number within a range.

  Parameters

  • minValue: number

    The minimum value.
  • maxValue: number

    The maximum value.

  Returns number

  A normalized random number within the specified range.

Static random

• random(lowerBound?, upperBound?): number

• Generates a pseudo-random number within the specified range.

  Parameters

  • lowerBound: number = 0

    The lower bound of the range.
  • upperBound: number = 1

    The upper bound of the range.

  Returns number

  A pseudo-random number within the specified range or from range [0,1]

Static randomChoice

• randomChoice<T>(array): T

• Randomly choose an element from an array.

  Type Parameters

  • T

  Parameters

  • array: T[]

    The array with elements to choose from.

  Returns T

  A randomly chosen element from the array.

Static randomSign

• randomSign(): number

• Generates a pseudo-random number that is either -1 or 1.

  Returns number

  -1 or 1.

Static weightedRandom

• weightedRandom(func): number

• Generate a weighted random number based on a function.

  Parameters

  • func: ((value) => number)

    The weighting function.

    • • (value): number

      • Parameters

        • value: number

        Returns number

  Returns number

  A weighted random number.
