- Changed random seed initialization so that it uses the system's
cryptographically secure random number generator, if available, instead of the current time. - Changed the random number generator from Lee Killough's algorithm to the SFMT607 variant of the Mersenne Twister. SVN r1507 (trunk)

|

**---------------------------------------------------------------------------
|
||||
**
|
||||
** This file employs the techniques for improving demo sync and backward
|
||||
** compatibility that Lee Killough introduced with BOOM. However, none of
|
||||
** the actual code he wrote is left. In contrast to BOOM, each RNG source
|
||||
** in ZDoom is implemented as a separate class instance that provides an
|
||||
** interface to the high-quality Mersenne Twister. See
|
||||
** <http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/SFMT/index.html>.
|
||||
**
|
||||
** As Killough's description from m_random.h is still mostly relevant,
|
||||
** here it is:
|
||||
** killough 2/16/98:
|
||||
**
|
||||
** Make every random number generator local to each control-equivalent block.
|
||||
** Critical for demo sync. The random number generators are made local to
|
||||
** reduce the chances of sync problems. In Doom, if a single random number
|
||||
** generator call was off, it would mess up all random number generators.
|
||||
** This reduces the chances of it happening by making each RNG local to a
|
||||
** control flow block.
|
||||
**
|
||||
** Notes to developers: if you want to reduce your demo sync hassles, follow
|
||||
** this rule: for each call to P_Random you add, add a new class to the enum
|
||||
** type below for each block of code which calls P_Random. If two calls to
|
||||
** P_Random are not in "control-equivalent blocks", i.e. there are any cases
|
||||
** where one is executed, and the other is not, put them in separate classes.

//
|

// Make every random number generator local to each control-equivalent block.
|

// Critical for demo sync. Changing the order of this list breaks all previous
|
||||
// versions' demos. The random number generators are made local to reduce the
|
||||
// chances of sync problems. In Doom, if a single random number generator call
|
||||
// was off, it would mess up all random number generators. This reduces the
|
||||
// chances of it happening by making each RNG local to a control flow block.
|
||||
//
|
||||
// Notes to developers: if you want to reduce your demo sync hassles, follow
|
||||
// this rule: for each call to P_Random you add, add a new class to the enum
|
||||
// type below for each block of code which calls P_Random. If two calls to
|
||||
// P_Random are not in "control-equivalent blocks", i.e. there are any cases
|
||||
// where one is executed, and the other is not, put them in separate classes.
|
||||
//
|
||||
// Keep all current entries in this list the same, and in the order

// indicated by the #'s, because they're critical for preserving demo
|
||||
// sync. Do not remove entries simply because they become unused later.
