Detailed Description

Random number generators (including the rand() in C) are often frustratingly non-random in their lower bits.

This is a fast random number that is random in its lower bits.

Member Function Documentation

U16 grinliz::Random::RandD2

(

U16

upperBound

)

[inline]

"Roll two dice." Return a result from [0,upperBound).

This has the same bell curve distribution as 2 dice.

U16 grinliz::Random::RandD3

(

U16

upperBound

)

[inline]

"Roll three dice." Return a result from [0,upperBound).

This has the same bell curve distribution as 3 dice.

void grinliz::Random::SetSeed

(

U32

_seed

)

The current seed can be set at any time.

This does put the random number generator in a consistent state, even though the random numbers are actually partially cached.
