srand() and rand() portability
Author
Of course they are standards so they are available where sdtio is but
I was thinking on adding replays to my game, the only problem is that some objects, specially the monsters' AI rely on random numbers.
So the question is : would equal srand() values generate the same results for rand() in different platforms? and if not, is there a library that allows this?
You could easily just obtain and use the code for a common prng, and explicitly use that instead:
//In .cpplong holdrand;//In .hppextern long holdrand;inline void srand(long seed){ holdrand = seed;}inline int rand(void){ return (((holdrand = holdrand * 214013L + 2531011L) >> 16) & 0x7fff);}
I vote for boost::random, too. Remember that rand() and other implementations like iMalcs aren't reentrant, so for multi-threaded apps they should be avoided anyway.
