Adding 5 extra bonuses (6/7 but till 10) causing CClientManager::RESULT_ITEM_LOAD raises error: Cannot access memory at address Dump
update 999, seems like after adding 3 bonuses on an item it is succesfuly inserted into the db, but client instantly crashes with no syserr when a item with the 3rd bonus is present on the char Do you guys have any advice on where I should add them on client side to be visible? I m expecting some range on python side or something like that but not sure where Fixed the unprocessed packets too, seems like having null attrs in db is not ok -

Adding 5 extra bonuses (6/7 but till 10) causing CClientManager::RESULT_ITEM_LOAD raises error: Cannot access memory at address Dump
So I'm trying to add 5 extra bonuses (6/7, but till 10) But with a catch too First 3 bonuses should be added from item_attr_rare table, last 2 from item_attr_rare_pvp (so i added a new table, duplicate from item attr rare) Then I proceeded to increase the item bonus count and limits: enum EItemMisc { ITEM_NAME_MAX_LEN = 24, ITEM_VALUES_MAX_NUM = 6, ITEM_SMALL_DESCR_MAX_LEN = 256, ITEM_LIMIT_MAX_NUM = 2, ITEM_APPLY_MAX_NUM = 3, ITEM_SOCKET_MAX_NUM = 3, ITEM_MAX_COUNT = 200, ITEM_ATTRIBUTE_NORM_NUM = 5, ITEM_ATTRIBUTE_RARE_NUM = 3, #ifdef BETTER_67 ITEM_ATTRIBUTE_RARE_PVP_NUM = 2, #endif ITEM_ATTRIBUTE_NORM_START = 0, ITEM_ATTRIBUTE_NORM_END = ITEM_ATTRIBUTE_NORM_START + ITEM_ATTRIBUTE_NORM_NUM, ITEM_ATTRIBUTE_RARE_START = ITEM_ATTRIBUTE_NORM_END, ITEM_ATTRIBUTE_RARE_END = ITEM_ATTRIBUTE_RARE_START + ITEM_ATTRIBUTE_RARE_NUM, #ifdef BETTER_67 ITEM_ATTRIBUTE_RARE_PVP_START = ITEM_ATTRIBUTE_RARE_END, #endif #ifdef BETTER_67 ITEM_ATTRIBUTE_RARE_PVP_END = ITEM_ATTRIBUTE_RARE_PVP_START + ITEM_ATTRIBUTE_RARE_PVP_NUM, ITEM_ATTRIBUTE_MAX_NUM = ITEM_ATTRIBUTE_RARE_PVP_END, // 7 #else ITEM_ATTRIBUTE_MAX_NUM = ITEM_ATTRIBUTE_RARE_END, // 7 #endif ITEM_ATTRIBUTE_MAX_LEVEL = 5, ITEM_AWARD_WHY_MAX_LEN = 50, REFINE_MATERIAL_MAX_NUM = 5, ITEM_ELK_VNUM = 50026, }; Created a new vector to store these new bonuses: std::vector<TItemAttrTable> m_vec_itemRarePvpTable; // New vector to store item_attr_rare_pvp data And now i read from the db, and for each row create a TItemAttrTable object, which i then add to the above vector: #ifdef BETTER_67 bool CClientManager::InitializeItemRarePvpTable() { char query[4096];

If so, could anybody point me in the right direction? Update, here, fixed the core crash, but I guess something didn't go as planned, altered item table, added the other columns for the new attrs, but somewhere i fucked up bcs now, inventory dosen't work, items are duplicated and alot of other things broke For cache i changed the fush method a bit void CItemCache::OnFlush() { if (m_data.vnum == 0) { char szQuery[QUERY_MAX_LEN]; snprintf(szQuery, sizeof(szQuery), "DELETE FROM item%s WHERE id=%u", GetTablePostfix(), m_data.id); CDBManager::instance().ReturnQuery(szQuery, QID_ITEM_DESTROY, 0, NULL); if (g_test_server) sys_log(0, "ItemCache::Flush : DELETE %u %s", m_data.id, szQuery); } else { TPlayerItem *p = &m_data; const auto setQuery = fmt::format(FMT_COMPILE("id={}, owner_id={}, `window`={}, pos={}, count={}, vnum={}, socket0={}, socket1={}, socket2={}, " "attrtype0={}, attrvalue0={}, " "attrtype1={}, attrvalue1={}, " "attrtype2={}, attrvalue2={}, " "attrtype3={}, attrvalue3={}, " "attrtype4={}, attrvalue4={}, " "attrtype5={}, attrvalue5={}, " "attrtype6={}, attrvalue6={} " #ifdef BETTER_67 ", attrtype7={}, attrvalue7={}, " "attrtype8={}, attrvalue8={}, " "attrtype9={}, attrvalue9={} " #endif ), p->id, p->owner, p->window, p->pos, p->count, p->vnum, p->alSockets[0], p->alSockets[1], p->alSockets[2], p->aAttr[0].bType, p->aAttr[0].sValue, p->aAttr[1].bType, p->aAttr[1].sValue, p->aAttr[2].bType, p->aAttr[2].sValue, p->aAttr[3].bType, p->aAttr[3].sValue, p->aAttr[4].bType, p->aAttr[4].sValue, p->aAttr[5].bType, p->aAttr[5].sValue, p->aAttr[6].bType, p->aAttr[6].sValue #ifdef BETTER_67 , p->aAttr[7].bType, p->aAttr[7].sValue, p->aAttr[8].bType, p->aAttr[8].sValue, p->aAttr[9].bType, p->aAttr[9].sValue #endif ); // @fixme205 const auto itemQuery = fmt::format(FMT_COMPILE("INSERT INTO item{} SET {} ON DUPLICATE KEY UPDATE {}"), GetTablePostfix(), setQuery, setQuery); if (g_test_server) sys_log(0, "ItemCache::Flush :REPLACE (%s)", itemQuery.c_str()); CDBManager::instance().ReturnQuery(itemQuery.c_str(), QID_ITEM_SAVE, 0, NULL); ++g_item_count; } m_bNeedQuery = false; } Is there any other place i gotta change caching? What basically happens now, client seems to not understand anything anymore, chat dosent work after the things start bugging out But hopefully i think i understand i m missing something on client side too bcs there are some chat packets that are being raised after moving items around in the inv 0528 13:29:18383 :: Unprocessed packet header 137, state Game 0528 13:29:19900 :: Unprocessed packet header 73, state Game 0528 13:29:24570 :: Unknown packet header: 102, last: 61 124 [Hidden Content] -

Where can i found the armors
Found the solution; .dds files are somewhat seems wrong in windows (got transparency in body parts) so i downloaded dds viewer from: [Hidden Content] that way i exported textures without transparency -

Snus2 German Server [ START 08.06.24 ]
This guy is known to be a scammer... He got banned on m2dl for scamming and now hes trying to take his serverfiles, he bought from somewhere, online the 2nd time... First time he was trying to get money out of the players as soon as they joined... He cant code and he cant edit the server at all. Dont trust him and make sure to keep your money. And dont expect any updates. He also is rude to a lot of people who exposed him or dont want to help. If its the same server like before you cant even play it till end game sooo... Just dont play it -

Where can i found the armors
Hey guys hello! I'm new here and not familiar with metin2 dev. Just downloadad full client's unpacked version from here. I am trying to find warrior armors such as monk plate, iron plate, tiger plate etc.. Just found .gr2 files with .dds textures in "\Unpacked_Client_v22.5.7.0\d_\ymir work\pc\warrior". Monk plate was named in warrior_nahan. But it's kinda like missing something in it. Here is the screenshot of what i've got so far; So, what i know so far is; there are dedicated textures to each armor in this game. and there are models for each armor. But textures of the armors have transparency. It looks like image above when i assign textures from .dds files which are located in the same directory as warrior_nahan.gr2 At the end of the day i guess i am missing something. What do you guys think? -

[Advice]Clever way to add just specific bonuse range from item_attr_rare?
So what I m trying to do is to add 5 extra special bonuses (basically 6/7 but up to 10) What I wanna do is: The first 3 special bonuses to be PVM Last 2 pvp What I really wanna do is to avoid creating a new ITEM_ATTRIBUTE_RARE_RARE and read from a whole different table and have to go through all the hustle Ideally I'd like to somehow have minimum changes to the existing 6/7 flow to be able to mark bonuses in the db somehow to the degree that Case 71051 adds 3 bonuses and only pvm from a list available only for case 71051 and Case 71052 adds 2 extra pvp fetched from a list available in 71052 The original base for 71051 is: case 71051 : { LPITEM item2; if (!IsValidItemPosition(DestCell) || !(item2 = GetInventoryItem(wDestCell))) return false; if (ITEM_COSTUME == item2->GetType()) // @fixme124 { ChatPacket(CHAT_TYPE_INFO, LC_TEXT("¼Ó¼ºÀ» º¯°æÇÒ ¼ö ¾ø´Â ¾ÆÀÌÅÛÀÔ´Ï´Ù.")); return false; } if (item2->IsExchanging() || item2->IsEquipped()) // @fixme114 return false; if (item2->GetAttributeSetIndex() == -1) { ChatPacket(CHAT_TYPE_INFO, LC_TEXT("¼Ó¼ºÀ» º¯°æÇÒ ¼ö ¾ø´Â ¾ÆÀÌÅÛÀÔ´Ï´Ù.")); return false; } #ifdef ENABLE_ITEM_RARE_ATTR_LEVEL_PCT if (item2->AddRareAttribute2()) #else if (item2->AddRareAttribute()) #endif { ChatPacket(CHAT_TYPE_INFO, LC_TEXT("¼º°øÀûÀ¸·Î ¼Ó¼ºÀÌ Ãß°¡ µÇ¾ú½À´Ï´Ù")); int iAddedIdx = item2->GetRareAttrCount() + 4; char buf[21]; snprintf(buf, sizeof(buf), "%u", item2->GetID()); LogManager::instance().ItemLog( GetPlayerID(), item2->GetAttributeType(iAddedIdx), item2->GetAttributeValue(iAddedIdx), item->GetID(), "ADD_RARE_ATTR", buf, GetDesc()->GetHostName(), item->GetOriginalVnum()); item->SetCount(item->GetCount() - 1); } else { ChatPacket(CHAT_TYPE_INFO, LC_TEXT("´õ ÀÌ»ó ÀÌ ¾ÆÀÌÅÛÀ¸·Î ¼Ó¼ºÀ» Ãß°¡ÇÒ ¼ö ¾ø½À´Ï´Ù")); } } break; The add rare attrs methods are: bool CItem::AddRareAttribute2(const int * aiAttrPercentTable) { int count = GetRareAttrCount(); if (count >= ITEM_ATTRIBUTE_RARE_NUM) return false; static const int aiItemAddAttributePercent[ITEM_ATTRIBUTE_MAX_LEVEL] = { 40, 50, 10, 0, 0 }; if (aiAttrPercentTable == NULL) aiAttrPercentTable = aiItemAddAttributePercent; if (GetRareAttrCount() < MAX_RARE_ATTR_NUM) PutRareAttribute(aiAttrPercentTable); return true; } void CItem::PutRareAttribute(const int * aiAttrPercentTable) { int iAttrLevelPercent = number(1, 100); int i; for (i = 0; i < ITEM_ATTRIBUTE_MAX_LEVEL; ++i) { if (iAttrLevelPercent <= aiAttrPercentTable[i]) break; iAttrLevelPercent -= aiAttrPercentTable[i]; } PutRareAttributeWithLevel(i + 1); } void CItem::PutRareAttributeWithLevel(BYTE bLevel) { int iAttributeSet = GetAttributeSetIndex(); if (iAttributeSet < 0) return; if (bLevel > ITEM_ATTRIBUTE_MAX_LEVEL) return; std::vector<int> avail; int total = 0; for (int i = 0; i < MAX_APPLY_NUM; ++i) { const TItemAttrTable & r = g_map_itemRare[i]; if (r.bMaxLevelBySet[iAttributeSet] && !HasRareAttr(i)) { avail.emplace_back(i); total += r.dwProb; } } unsigned int prob = number(1, total); int attr_idx = APPLY_NONE; for (DWORD i = 0; i < avail.size(); ++i) { const TItemAttrTable & r = g_map_itemRare[avail[i]]; if (prob <= r.dwProb) { attr_idx = avail[i]; break; } prob -= r.dwProb; } if (!attr_idx) { sys_err("Cannot put item rare attribute %d %d", iAttributeSet, bLevel); return; } const TItemAttrTable & r = g_map_itemRare[attr_idx]; if (bLevel > r.bMaxLevelBySet[iAttributeSet]) bLevel = r.bMaxLevelBySet[iAttributeSet]; AddRareAttr(attr_idx, bLevel); } void CItem::AddRareAttr(BYTE bApply, BYTE bLevel) { if (HasRareAttr(bApply)) return; if (bLevel <= 0) return; int i = ITEM_ATTRIBUTE_RARE_START + GetRareAttrCount(); if (i == ITEM_ATTRIBUTE_RARE_END) sys_err("item rare attribute overflow!"); else { const TItemAttrTable & r = g_map_itemRare[bApply]; long lVal = r.lValues[MIN(4, bLevel - 1)]; if (lVal) SetForceAttribute(i, bApply, lVal); } } Would the easiest way to do it is to just create a new table, right?
