Member Function Documentation

InUnitSphere()

Vector3 Util.Random.InUnitSphere ( )

inlinestatic

Random vector3 point inside unit sphere.

Note that this produces a non uniform distribution.

Next()

uint Util.Random.Next ( )

inlinestaticprivate

RandomizeSeed()

void Util.Random.RandomizeSeed ( )

inlinestatic

Randomize the seed for the RNG.

Range() [1/2]

float Util.Random.Range ( float min, float max )

inlinestatic

Random float in [min, max).

Range() [2/2]

int Util.Random.Range ( int min, int max )

inlinestatic

Random integer in [min, max).

RotateLeft()

uint Util.Random.RotateLeft ( uint x, int k )

inlinestaticprivate

Seed()

void Util.Random.Seed ( ulong seed )

inlinestatic

Select a specific seed for the RNG.

Smooth()

float Util.Random.Smooth ( float seed )

inlinestatic

Returns a smooth "random" number based on seed.

Random value will be between approximately -1.0f and 1.0f (not exact!). If seed is increased, the random number will smoothly "slide" towards a new "point".
