コードサンプル

Datatype.Random

local max = 2147483647 -- use a large integer
local seed = math.random(max)
local generator = Random.new(seed)

方法

NextInteger

Returns a pseudorandom integer uniformly distributed over [min, max].

パラメータ

min: number
max: number

戻り値

NextNumber

Returns a pseudorandom number uniformly distributed over [0, 1].

戻り値

NextNumber

Returns a pseudorandom number uniformly distributed over [min, max].

パラメータ

min: number
max: number

戻り値

Shuffle

void

Uniformly shuffles the array part of tb in-place using NextInteger to pick indices. If there are any nil "holes" in the array part of the table, Shuffle throws an error, since shuffling could change the length.

The hash part of tb is ignored. No metamethods of tb are invoked.

The shuffle is defined to be a Fisher-Yates shuffle so the number of NextInteger calls is guaranteed to be consistent between engine versions for a given size of table.

パラメータ

tb: table

void

NextUnitVector

Returns a unit vector with a pseudorandom direction. Vectors returned from this function are uniformly distributed over the unit sphere.

戻り値

A unit vector with a pseudorandom direction.

Clone

Returns a new Random object with the same state as the original.
