sharing exp penalties amongst group

nilbog · #1 03-16-2009, 12:37 PM

After enabling the class/race based experience penalties, I am curious as how to share those penalties amongst the group.

Code:

//Uncomment this to enable Race and Class based XP modifiers (removed from live)
//#define USE_RACE_CLASS_XP_MODS

Works great.. and now the halfling warriors are leveling a hell of a lot faster than the troll shadowknights. But, originally, these penalties were split amongst your group, if you were grouped.

Here's the producer's letter from 1/14/01 defining how the penalties worked, and how they were changed.

The relevant information from that link is this though:

Quote:

In regards to the sharing of the experience penalty, it was apparent in beta, before the penalty was shared, that those playing characters without an experience penalty leveled faster than those that did. It was obvious that this would occur, but it was to the extreme that a group of friends, all playing together, would become separated to the point that they could no longer group efficiently in the mid to upper-mid levels. So we chose to distribute experience in the group on the basis of the total experience of each member rather than the level, in order to keep groups together.

Here's what I see defined in source.

Code:

29 //experience modifiers based on race and class, used if USE_RACE_CLASS_XP_MODS is defined
   30 //                            hum     bar     eru     elf     hie     def     hef     dwa     tro     ogr     hal    gno     iks,    vah     frog
   31 float  race_modifiers[15] = { 100.0f, 105.0f, 100.0f, 100.0f, 100.0f, 100.0f, 100.0f, 100.0f, 120.0f, 115.0f, 95.0f, 100.0f, 120.0f, 100.0f, 100.0f}; // Quagmire - Guessed on iks and vah
   32 
   33 //                            war   cle    pal    ran    shd    dru    mnk    brd    rog    shm    nec    wiz    mag    enc    bst    bes
   34 float class_modifiers[16] = { 9.0f, 10.0f, 14.0f, 14.0f, 14.0f, 10.0f, 12.0f, 14.0f, 9.05f, 10.0f, 11.0f, 11.0f, 11.0f, 11.0f, 10.0f, 10.0f};

  328 {
  329 
  330 	int16 check_levelm1 = check_level-1;
  331 	float mod;
  332 	if (check_level < 31)
  333 		mod = 1.0;
  334 	else if (check_level < 36)
  335 		mod = 1.1;
  336 	else if (check_level < 41)

  362 
  363 	float base = (check_levelm1)*(check_levelm1)*(check_levelm1);
  364 
  365 #ifdef USE_RACE_CLASS_XP_MODS
  366 	int16 tmprace = GetBaseRace();
  367 	if (tmprace == IKSAR) // Quagmire, set these up so they read from array right
  368 		tmprace = 12;
  369 	else if (tmprace == VAHSHIR)
  370 		tmprace = 13;
  371 	else if ((tmprace == FROGLOK) || (tmprace == FROGLOK2))
  372 		tmprace = 14;
  373 	else
  374 		tmprace--;
  375 
  376 	if (tmprace >= sizeof(race_modifiers) || GetClass() < 1 || GetClass() - 1 >= PLAYER_CLASS_COUNT)
  377 		return 0xFFFFFFFF;
  378 
  379 	mod *= class_modifiers[GetClass()-1]*race_modifiers[tmprace];
  380 #else
  381 	mod *= 1000;
  382 #endif
  383 
  384 	return(uint32(base * mod));
  385 }

Anyone have any thoughts/ideas about this?
