Programação NPC só vende pra main backpack

blackz · October 17, 2020

Buenas a todos, eu uso TFS 0.4, rev 4393 (8.71), eu gostaria que o NPC ao vender algo na loja, consultasse se o main backpack (a que fica no inventário) tem slot disponível pra concluir a venda, se não ele não vende e avisa o motivo. Eu acredito que seja no "sendGoods()" em algum desses arquivos a seguir, porém eu não sei fazer, alguém consegue me ajudar?

PLAYER.CPP

void Player::updateInventoryGoods(uint32_t itemId)
{
	if(Item::items[itemId].worth)
	{
		sendGoods();
		return;
	}

	for(ShopInfoList::iterator it = shopOffer.begin(); it != shopOffer.end(); ++it)
	{
		if(it->itemId != itemId)
			continue;

		sendGoods();
		break;
	}
}

NPC.CPP (provavelmente na penúltima linha desse)

void Npc::onPlayerTrade(Player* player, ShopEvent_t type, int32_t callback, uint16_t itemId, uint8_t count,
	uint8_t amount, bool ignore/* = false*/, bool inBackpacks/* = false*/)
{
	if(type == SHOPEVENT_BUY)
	{
		if(NpcState* npcState = getState(player, true))
		{
			npcState->amount = amount;
			npcState->subType = count;
			npcState->itemId = itemId;
			npcState->buyPrice = getListItemPrice(itemId, SHOPEVENT_BUY);
			npcState->ignore = ignore;
			npcState->inBackpacks = inBackpacks;

			const NpcResponse* response = getResponse(player, npcState, EVENT_PLAYER_SHOPBUY);
			executeResponse(player, npcState, response);
		}
	}
	else if(type == SHOPEVENT_SELL)
	{
		if(NpcState* npcState = getState(player, true))
		{
			npcState->amount = amount;
			npcState->subType = count;
			npcState->itemId = itemId;
			npcState->sellPrice = getListItemPrice(itemId, SHOPEVENT_SELL);
			npcState->ignore = ignore;

			const NpcResponse* response = getResponse(player, npcState, EVENT_PLAYER_SHOPSELL);
			executeResponse(player, npcState, response);
		}
	}

	if(m_npcEventHandler)
		m_npcEventHandler->onPlayerTrade(player, callback, itemId, count, amount, ignore, inBackpacks);

	player->sendGoods();
}

PROTOCOLGAME.CPP

void ProtocolGame::sendGoods(const ShopInfoList& shop)
{
	NetworkMessage_ptr msg = getOutputBuffer();
	if(msg)
	{
		TRACK_MESSAGE(msg);
		msg->put<char>(0x7B);
		msg->put<uint32_t>((uint32_t)g_game.getMoney(player));

		std::map<uint32_t, uint32_t> goodsMap;
		if(shop.size() >= 5)
		{
			for(ShopInfoList::const_iterator sit = shop.begin(); sit != shop.end(); ++sit)
			{
				if(sit->sellPrice < 0)
					continue;

				int8_t subType = -1;
				if(sit->subType)
				{
					const ItemType& it = Item::items[sit->itemId];
					if(it.hasSubType() && !it.stackable)
						subType = sit->subType;
				}

				uint32_t count = player->__getItemTypeCount(sit->itemId, subType);
				if(count > 0)
					goodsMap[sit->itemId] = count;
			}
		}
		else
		{
			std::map<uint32_t, uint32_t> tmpMap;
			player->__getAllItemTypeCount(tmpMap);
			for(ShopInfoList::const_iterator sit = shop.begin(); sit != shop.end(); ++sit)
			{
				if(sit->sellPrice < 0)
					continue;

				int8_t subType = -1;
				const ItemType& it = Item::items[sit->itemId];
				if(sit->subType && it.hasSubType() && !it.stackable)
					subType = sit->subType;

				if(subType != -1)
				{
					uint32_t count = subType;
					if(!it.isFluidContainer() && !it.isSplash())
						count = player->__getItemTypeCount(sit->itemId, subType);

					if(count > 0)
						goodsMap[sit->itemId] = count;
					else
						goodsMap[sit->itemId] = 0;
				}
				else
					goodsMap[sit->itemId] = tmpMap[sit->itemId];
			}
		}

		msg->put<char>(std::min(goodsMap.size(), (size_t)255));
		std::map<uint32_t, uint32_t>::const_iterator it = goodsMap.begin();
		for(uint32_t i = 0; it != goodsMap.end() && i < 255; ++it, ++i)
		{
			msg->putItemId(it->first);
			msg->put<char>(std::min(it->second, (uint32_t)255));
		}
	}
}
