GM Skill Training has no Cost
Currently, when someone trains a skill at their class GM, it shows on the client that it is subtracting the amount of coin that it is supposed to, but when you zone, the coin reappears in your inventory. It looks like the problem is that we don't do any coin removal in the code for GM training here:
client_process.cpp
Code:
void Client::OPGMTrainSkill(const EQApplicationPacket *app)
{
if(!m_pp.points)
return;
GMSkillChange_Struct* gmskill = (GMSkillChange_Struct*) app->pBuffer;
Mob* pTrainer = entity_list.GetMob(gmskill->npcid);
if(!pTrainer || !pTrainer->IsNPC() || pTrainer->GetClass() < WARRIORGM || pTrainer->GetClass() > BERSERKERGM)
return;
//you can only use your own trainer, client enforces this, but why trust it
int trains_class = pTrainer->GetClass() - (WARRIORGM - WARRIOR);
if(GetClass() != trains_class)
return;
//you have to be somewhat close to a trainer to be properly using them
if(DistNoRoot(*pTrainer) > USE_NPC_RANGE2)
return;
if (gmskill->skillbank == 0x01)
{
// languages go here
if (gmskill->skill_id > 25)
{
cout << "Wrong Training Skill (languages)" << endl;
DumpPacket(app);
return;
}
cout << "Training language: " << gmskill->skill_id << endl;
IncreaseLanguageSkill(gmskill->skill_id);
}
else if (gmskill->skillbank == 0x00)
{
// normal skills go here
if (gmskill->skill_id > HIGHEST_SKILL)
{
cout << "Wrong Training Skill (abilities)" << endl;
DumpPacket(app);
return;
}
SkillType skill = (SkillType) gmskill->skill_id;
if(!CanHaveSkill(skill)) {
mlog(CLIENT__ERROR, "Tried to train skill %d, which is not allowed.", skill);
return;
}
int16 skilllevel = GetRawSkill(skill);
if(skilllevel == 0) {
//this is a new skill..
int16 t_level = SkillTrainLevel(skill, GetClass());
if (t_level == 0)
{
return;
}
SetSkill(skill, t_level);
} else {
switch(skill) {
case BREWING:
case MAKE_POISON:
case TINKERING:
case RESEARCH:
case ALCHEMY:
case BAKING:
case TAILORING:
case BLACKSMITHING:
case FLETCHING:
case JEWELRY_MAKING:
case POTTERY:
if(skilllevel >= RuleI(Skills, MaxTrainTradeskills)) {
Message_StringID(13, MORE_SKILLED_THAN_I, pTrainer->GetCleanName());
return;
}
default:
break;
}
// Client train a valid skill
SetSkill(skill, skilllevel + 1);
}
}
m_pp.points--;
}
I will try to figure out the formula for skill prices and if I can, I will try to use the same code that is used when purchasing items from merchants to allow GM Training to actually have a cost.
If anyone has suggestions or other info on this, feel free to post it

Looks like this is where merchants take money for buying items, so some of the code should be usable for GM Trainers once the formula for prices on skills is figured out.
client_packet.cpp
Code:
void Client::Handle_OP_ShopPlayerBuy(const EQApplicationPacket *app)

RDTSC_Timer t1;
t1.start();

LogFile->write(EQEMuLog::Debug, "%s, purchase item..", GetName());
DumpPacket(app);
#endif
int merchantid;
bool tmpmer_used = false;
Mob* tmp = entity_list.GetMob(mp->npcid);
if (tmp == 0 || !tmp->IsNPC() || tmp->GetClass() != MERCHANT)
return;
if (mp->quantity < 1) return;
//you have to be somewhat close to them to be properly using them
if(DistNoRoot(*tmp) > USE_NPC_RANGE2)

Well, unfortunately, it looks like they don't set skill costs with any type of formula as far as I can tell. So, I think we have to just get each one manually. I started a list and have the first 100 done. Only 300 more to go lol :P
Code:
Skill - Cost in Copper Pieces
1 - 0
2 - 0
3 - 0
4 - 0

With the numbers you've posted,
price = 0.001169 (level ^ 3.4) - 44.17
is very close for level >= 10, error at level 100 is 0.57%, which is 42 coppers.
Give me the other values and I'll give you a better formula.
The above formula may not work for higher levels, but it's almost certainly a polynomial curve.

Typo:
The formula I posted is good for level >= 31.
I would think that by PC level 5 the chances are that the char would have at least 2pp, so the insignigicant error for higher levels wouldn't matter. Use a lookup tables for the lower levels (where my formula fails spectacularly).
I'll put more than 5 minutes into it later today.

Whatever the formula is (if there is one), it starts at 15, so you would probably do (skill level - 14) before doing any other math to it.
I think a close formula would be good enough as long as it doesn't ever exceed the actual cost that the client sees. If it ever costs more than what the client sees, it could potentially cause issues. At the very least, people might not understand why they are unable to buy a skill that they believe they have enough to pay for. I will edit in the rest of the number up to 400 when I get time. It is boring work, but shouldn't take more than an hour or 2 I think. Though, once I have all of the numbers, we could probably just use them so that they are 100% accurate instead of a formula that is close to accurate.
