well, it just returns the index of the weapon you wanna buy ... actual buying has to be done elsewhere and since it's everywhere in CS the same, no need to post this here

nice idea to put the weapons prizes on a logarithmic scale and then select them via random function on this scale ... does that give good results ?

and why do you use this RANDOM_LONG with the prize ? I think one should avoid this here for the sake of clear code, since you already have a random function later on, so why here ?

the data structures to which the p points are updated when the actual weapon is bought ?

I make all my weapon pickups/dropping/buying/handling decisions through a BotRateWeapon() function...
Code:
int BotRateWeapon (player_t *pPlayer, weaponspec_t *weapon_spec)
{
   // this function returns an integer value describing how much a particular weapon (passed by
   // the "weapon" pointer) is interesting for the bot whose player structure is pointed to by
   // pPlayer. The more interesting the weapon, the higher the number this function returns.
   // FIXME: quick and dirty, empirical. Redo this right.
   int score;
   // does the bot already have this weapon ?
   if (pPlayer->weapons[weapon_spec->index].is_present)
	  return (0); // then this weapon is of no interest for the bot
   // first reset the weapon score
   score = 0;
   // rate the interest regarding the weapon class
   // is weapon primary AND has bot no primary weapon yet ?
   if ((weapon_spec->weapon_class == WEAPON_CLASS_PRIMARY)
	   && !PlayerHasWeaponOfClass (pPlayer, WEAPON_CLASS_PRIMARY))
	  score += 500; // then weapon is highly interesting, add 500 in a row
   // else is weapon secondary AND has bot no secondary weapon yet ?
   else if ((weapon_spec->weapon_class == WEAPON_CLASS_SECONDARY)
			&& !PlayerHasWeaponOfClass (pPlayer, WEAPON_CLASS_SECONDARY))
	  score += 500; // then weapon is highly interesting, add 500 in a row

			&& !PlayerHasWeaponOfClass (pPlayer, WEAPON_CLASS_GRENADE))
	  score += 500; // then weapon is highly interesting, add 500 in a row
   // rate the interest regarding the bot's personal weapon preference
   // is this weapon the bot's preferred weapon AND the bot doesn't own that weapon yet ?
   if ((strcmp (weapon_spec->classname, pPlayer->Bot.pProfile->preferred_weapon) == 0)
	   && !PlayerHasWeapon (pPlayer, weapon_spec))
	   score += 500; // then weapon is highly interesting, add 500 in a row

using the log10() to select the weapon can ensure that there are higher possibility to select "better" weapon and lower possibility to select "worse" weapon
the possibility is also depending on money

also the "p" points to a std::vector<int> which is a table similar to POD-Bot. it just chooses one of them depending on current bot's aggression value.

   }
  }  // end of cs 1.6 part
 }	// We actually gonna buy this weapon
}
its personality related (favorite weapon, etc)
its cs 1.5/1.6 compatible
its not _as and _es compatible (maps)
it has some sort of scoring system
its output relies on the ini parsed information from buytable.ini

piece of buytable.ini

An effective but low tech way of having bots select good weapons for a given map, is to have a map "scenario" file which can specify which weapons are most effective for the type of map in use. A scenario file can specify much more, such as which personalities are best, weapon type distribution (eg 2 snipers, 3 shotgun, etc), and so on.

good point, but this can be done automatically if the bots keep track themselves of which weapons are useful for which map. Let's let them discover it by themselves, it's always funnier
