RandomNumberGenerator

Implements a pseudo-random number generator using a 64 bit Fibonacci LFSR.

Example uses: * rng.seed() % maxAmount * (rng.seed() % 100) < probabilityOfEvent

struct RandomNumberGenerator {

this(ulong reg);

ulong seed();

ulong dice(uint s);

ulong opCall();

}

Constructors

this this(ulong reg): Creates the LFSR, and initializes it by calling its seed function 64 times.

Members

Functions

dice ulong dice(uint s): Calls seed, then returns the remainder of the seed divided by s. Intended to simplify the use of rng.seed() % s style of use of this
opCall ulong opCall(): Undocumented in source. Be warned that the author may not have intended to support it.
seed ulong seed(): Shuffles the register's content, then returns it.

Variables

reg ulong reg;: Undocumented in source.
