No gains for illegially equipped items
First a fix to support Frogloks and Berserkers
Code:
bool ItemInst::IsEquipable(int16 race, int16 class_) const
{
if (!m_item)
return false;
bool israce = false;
bool isclass = false;
if (m_item->Slots == 0) {
return false;
}
uint32 classes_ = m_item->Classes;
uint32 races_ = m_item->Races;
int32 race_ = 0;
#ifndef PACKETCOLLECTOR
race_ = GetArrayRace(race);
race_ = (race_==17? 15 : race_);
#endif
// @merth: can this be optimized? i.e., will (race & common->Races) suffice?
for (int cur_class = 1; cur_class<=16; cur_class++) {
if (classes_ % 2 == 1) {
if (cur_class == class_) {
isclass = true;
}
}
classes_ >>= 1;
}
for (unsigned int cur_race = 1; cur_race <= 15; cur_race++) {
if (races_ % 2 == 1) {
if (cur_race == race_) {
israce = true;
}
}
races_ >>= 1;
}
if (!isclass){printf("CLASS FAILED:%i ",class_);}
if (!israce){printf("RACE FAILED:%i ",race_);}
return (israce && isclass);
}
Update to allow new aug bool used in function
Code:
void AddItemBonuses(const ItemInst *inst, StatBonuses* newbon, bool isaug = false);
function now makes a return if player does not meet level requirement, class requirement, race requirement, or if a non-augment item is inserted into an augment slot. Slot check is currently commented due to GetCurrentSlot() returning bad values.
Please excuse the return functions not being combined, left them separate while i was testing each part.
Code:
void Client::AddItemBonuses(const ItemInst *inst, StatBonuses* newbon, bool isaug) {
if(!inst || !inst->IsType(ItemClassCommon))
{
return;
}
if (GetLevel() < inst->GetItem()->ReqLevel)
{
//printf("LEVEL FAILED:%i < %i ",GetLevel(),inst->GetItem()->ReqLevel);
return;
}
if (!inst->IsEquipable(GetBaseRace(),GetClass()))
{
return;
}
if(inst->GetAugmentType()==0 && isaug == TRUE)
{
//printf("AUG FAILED:%i ",inst->GetAugmentType());
return;
}
//if(!inst->IsEquipable(inst->GetCurrentSlot()))
//{
// printf("SLOT FAILED:%i ",inst->GetCurrentSlot());
//}
const Item_Struct *item = inst->GetItem();
if( GetLevel() >= item->RecLevel)
{
newbon->AC += item->AC;
newbon->HP += item->HP;

insert this where convienient in
int Mob::GetWeaponDamage(Mob *against, const ItemInst *weapon_item)
currently have it at the bottom; prevents illegally equipped weapons from doing damage
Code:
if(weapon_item){
if(weapon_item->GetItem() && GetLevel() < weapon_item->GetItem()->ReqLevel && weapon_item->IsEquipable(GetBaseRace(),GetClass()))
{
dmg = 0;
}
}

Disregard that last code block, noticed the logic was wrong, here is the correct code:
Code:
if(weapon_item){
if(weapon_item->GetItem() && ( GetLevel() < weapon_item->GetItem()->ReqLevel || !weapon_item->IsEquipable(GetBaseRace(),GetClass())))
{
dmg = 0;
}
}

This looks very very good. I know that the server code can definitely use some more hardening against exploits of this type. That being said, I hope this makes it into the tree.
Thank you!

Just make sure to comment all my printf functions, they get pretty spammy in the console at times. Been running this on my test server for almost 2 weeks now, haven't had any crashes related to it. Sadly all my MacroQuest Players quit.... wonder why? ^^

Awesome!

mhm
Code:
race_ = (race_==17? 15 : race_);
is kinda hackish but we'll see what we can do with it. |
