Guys, like BAIL just said...it's already there along with.
Code:
/* Returns an array of hacks that a given user is using with the number of hacks. */
native get_user_hacking(id , HackingType:hacks[] , &num)
and get_players has a secret flag (flag "x") and you supply the HackingType:hacks[] after and it will return all the players with the given hacks. Works like flags "e" and "f" with passing of the hacks array.
You guys are really behind on these things aren't you?
