ItemType structure for CO1?

[Nusku]

I was wondering if anyone here has the itemtype structure for CO1 / early CO2 (around patch 4300). I noticed that it's a binary format and not encrypted, but I am not entirely sure what the structure for each item is.

Forgot to update - I figured it out shortly after! I'll post this in case anyone else needs this info (I used the leaked EO source for the info)

Here is the struct:

typedef struct
{
	unsigned int	uID;					//0 item type 的 ID		//  精灵的lookface根据itemtype 定义
	char			szName[_MAX_NAMESIZE];	//1 物品名字			
	unsigned char	ucRequiredProfession;	//2 要求职业			附加属性类型		
	unsigned char	ucRequiredWeaponSkill;	//3 要求的武器技能
	unsigned char	ucRequiredLevel;		//4 要求的等级			// 精灵等级 装备精灵的玩家的等级必须不能少于精灵的等级×2。
	unsigned char	ucRequiredSex;			//5 要求的性别				
	unsigned short	usRequiredForce;		//6 要求力量
	unsigned short	usRequiredSpeed;		//7 要求速度
	unsigned short	usRequiredHealth; 		//8 要求健康
	unsigned short	usRequiredSoul; 		//9 要求精神			
	unsigned char	ucMonopoly;				//10 独占物品标志
	unsigned short	usWeight;				//11 物品重量
	unsigned int	uPrice;					//12 价格
	//int				uLuck;					//13 幸运值				//	升级到下一级需要的经验值 - not used in CO
	unsigned int	uUnknown;			
	unsigned short	usMaxAttack;			//14 最大攻击	
	unsigned short	usMinAttack;			//15 最小攻击
	short			usDefense;				//16 防御		
	short			usDexterity;			//17 敏捷				// 最小魔攻击
	short			usDodge;				//18 闪避				// add soul
	short			sLife;					//19 生命
	short			sMana;					//20 魔法力
	unsigned short	usAmount;				//21 数量				//	精灵亲密度=忠诚 - dura
	unsigned short	usAmountLimit;			//22 数量				//  精灵附加属性 // 显示时应当 /100 - maxdura
	unsigned char	ucStatus;				//23 状态			 - not sure	
	unsigned char	ucGem1;					//24 镶嵌宝石1			
	unsigned char	ucGem2;					//25 镶嵌宝石2
	unsigned char	ucMagic1;				//26 附加魔法1
	unsigned char	ucMagic2;				//27 幸运
	unsigned char	ucMagic3;				//28 追加
	unsigned short	usMagicAttack;			//29 魔攻				// 最大魔攻			
	unsigned short	usMagicDefence;			//30 魔防				
	unsigned short  usRange;				//31 攻击范围
	unsigned short  usAttackSpeed;			//32 攻击速度
	//int		     	nHitarte;				//33 命中 not used
	//unsigned short  usTarget;				//34 使用对象 not used
	char			szDesc[128];			//35 描述
}ItemTypeInfo;

And as for reading it... its a bit complex, but you get the idea from here (it's a lookup table basically):

CItemData::CItemData()
{
	m_dwRecordAmount = 0;
	m_pIDIndex = NULL;
	m_fp = NULL;
	char szFilename[]="ini/itemtype.dat";
	m_fp = fopen(szFilename, "rb");
	MYASSERT(m_fp);
	this->CreateIndexTable();
	FILE* fp = fopen("ini/itemnamelist.ini", "r");
	if(fp)
	{
		char szLine[1024] = "";
		while(true)
		{
			if (1 != fscanf(fp,"%s\n", szLine))
				break;
			if(strlen(szLine) == 0)
				continue;
			std::string str	= szLine;
			m_setItemName.push_back(str);
		}
		fclose(fp);
	}
	this->CreateAdditionalInfo();
}

BOOL CItemData::CreateIndexTable()
{
	// 创建索引表
	// 取记录条数
	fread(&m_dwRecordAmount, sizeof(DWORD), 1, m_fp);
	// 为ID索引表分配内存
	m_pIDIndex = new OBJID[m_dwRecordAmount];
	MYASSERT(m_pIDIndex);
	// 读取ID索引
	fread(m_pIDIndex, sizeof(OBJID), m_dwRecordAmount, m_fp);

	return true;
}

BOOL CItemData::GetItemTypeInfo(OBJID idType, ItemTypeInfo& infoItemType)
{
	MAP_ITEMINFO::iterator itr = s_mapItemType.find(idType);
	if (itr != s_mapItemType.end())
	{
		memcpy(&infoItemType, &itr->second, sizeof(ItemTypeInfo));
		return true;
	}
	
	if(!m_pIDIndex)
		return false;
	// 初始化定位信息 -1 为没有找到
	int nLocate = -1;
	// 查找索引表, 当ItemType表超过300时考虑做多级索引
	for(DWORD i = 0; i < m_dwRecordAmount; i++)
	{
		OBJID* pObjID = m_pIDIndex + i;
		OBJID idItem = *pObjID;
		if(*pObjID == idType)
		{
			nLocate = i;
			break;
		}
	}

	// 看看索引表中有没有
	if(nLocate < 0)
		return false;
	
	// 定位文件指针
	DWORD dwOffset = sizeof(DWORD) + 
						sizeof(OBJID) * m_dwRecordAmount + 
						sizeof(ItemTypeInfo) * nLocate;
	fseek(m_fp, dwOffset, SEEK_SET);

	// 读记录
	fread(&infoItemType, sizeof(ItemTypeInfo), 1, m_fp);

	// save type info
	s_mapItemType.insert(MAP_ITEMINFO::value_type(idType, infoItemType));
	return true;
}
