i found some work of Drammel at the project citadel and he had a Flank validation check but i felt it wasnt accurate enough, so started doing some tests and i did this script. What i need is some help and outsider eyes to find out things i haven't realized, and also to make it more efficient. I've no used nwn2 condition to flank (the creature is not attacking the one who gets the sneak attack) as it's not a  PnP  rule. IsFlankValid(object oPC, object oTarget, int bMelee = FALSE) is the starting point

float nDistAppearance(object oTarget, int sCheck = 1)
{
  if(sCheck == 1)
  {
    object oWeapon = GetItemInSlot(INVENTORY_SLOT_RIGHTHAND, oTarget);
    if(!GetWeaponRanged(oWeapon) && GetIsObjectValid(oWeapon))
    {
      int nWeaponType = GetBaseItemType(oWeapon);
      return StringToFloat(Get2DAString("baseitems", "PrefAttackDist", nWeaponType));
    }
  }
  int nType = GetAppearanceType(oTarget);
  string sColumn;
  if(sCheck == 1)
    sColumn = "PREFATCKDIST";
  else if(sCheck == 0)
    sColumn = "CREPERSPACE";
  else
    sColumn = "HITDIST";
  if(nType == APPEARANCE_TYPE_INVALID)
    return 0.0;
  else
    return StringToFloat(Get2DAString("appearance", sColumn, nType));
}

//determines if oFlanker is threatening oTarget's area

   if(GetIsDead(oFlanker))
