Reduce server memory usage
The problem: Mobs are using CHARACTER_POINT_INSTANT struct, which contains fixed size arrays for dragon soul, items etc. For every mob these arrays are allocating memory, but mobs obviously don't use items... The solution: Replace fixed size arrays with std::map or other data type From my own testing i saw over 70% memory usage reduction with special inventory system and optimized variables listed below: bItemGrid pItems pDSItems wDSItemGrid Below i am sharing example implementation in clean source for bItemGrid variable //in char.cpp at the end of void CHARACTER::Initialize() function add #ifdef ENABLE_ITEM_GRID_MAP m_pointsInstant.pItemsGridMap.clear(); #endif //in char.h after function LPITEM GetInventoryItem add #ifdef ENABLE_ITEM_GRID_MAP BYTE ItemGridMapGetConst(BYTE cell_index) const; #endif //in char.h replace BYTE bItemGrid[INVENTORY_AND_EQUIP_SLOT_MAX]; with #ifdef ENABLE_ITEM_GRID_MAP std::map<BYTE, BYTE> pItemsGridMap; #else BYTE bItemGrid[INVENTORY_AND_EQUIP_SLOT_MAX]; #endif //in char_item.cpp replace function CHARACTER::SetItem with void CHARACTER::SetItem(TItemPos Cell, LPITEM pItem) { WORD wCell = Cell.cell; BYTE window_type = Cell.window_type; if ((unsigned long)((CItem*)pItem) == 0xff || (unsigned long)((CItem*)pItem) == 0xffffffff) { sys_err("!!! FATAL ERROR !!! item == 0xff (char: %s cell: %u)", GetName(), wCell); core_dump(); return; } if (pItem && pItem->GetOwner()) { assert(!"GetOwner exist"); return; } switch(window_type) { case INVENTORY: case EQUIPMENT: { if (wCell >= INVENTORY_AND_EQUIP_SLOT_MAX) { sys_err("CHARACTER::SetItem: invalid item cell %d", wCell); return; } LPITEM pOld = m_pointsInstant.pItems[wCell]; if (pOld) { if (wCell < INVENTORY_MAX_NUM) { for (int i = 0; i < pOld->GetSize(); ++i) { int p = wCell + (i * 5); if (p >= INVENTORY_MAX_NUM) continue;

Use BeltInventory slots without Belt
It has one bug I can't solve. The problem is: When I drag an item(first item) to another item(second item), the second item disappears and the first item goes to the second item slot, and the second item just disappears. If i log out, or restart the client nothing will happen only when I restart the server. When I restart the server the second item which is disappers, will appear again. Solved, i'll update the post. -
