Detailed Description

A random number generator for int, float and double values.

You can always define min and max values (a range) where random numbers are generated. You must call randinit() first, otherwise this class will generate predictable numbers (not random numbers).

Member Function Documentation

irr::f64 Random::randdouble (  irr::f64  min, irr::f64  max )

Generates a psuedo-random double between min and max. Parameters: min  : A double as minimum range border. max  : A double as maximum range border.

irr::f64 Random::randdouble (  irr::f64  max  )

Generates a psuedo-random double between 0.0 and max. Parameters: max  : A double as maximum range border.

irr::f32 Random::randfloat (  irr::f32  min, irr::f32  max )

Generates a psuedo-random float between min and max. Parameters: min  : A float as minimum range border. max  : A float as maximum range border.

irr::f32 Random::randfloat (  irr::f32  max  )

Generates a psuedo-random float between 0.0 and max. Parameters: max  : A float as maximum range border.

irr::s32 Random::randint (  irr::s32  min, irr::s32  max )

Generates a psuedo-random integer between min and max. Parameters: min  : A signed integer as minimum range border. max  : A signed integer as maximum range border.

irr::s32 Random::randint (  irr::s32  max  )

Generates a psuedo-random integer between 0 and max. Parameters: max  : A signed integer as maximum range border.
