Resources in trading

[ArneHD]

In paticular, the number of resources in trading. I am trying to make a mod where I can trade more than one resource from and to a nation. For example I buy three spice from Civ A and then sell one to Civ B and Civ C. I didn't think this would be too difficult, but it turned out I was wrong.

First i checked the Pyton file: CvDiplomacy, and found that it was all about the reactions you got from the AI. I then went for the SDK where I found CyDeal a much better contestant. Here I ran onto another pitfall, I couldn't understand a thing of it. So, here is my question: Can anyone make any sense out of this:

CyDeal::CyDeal(CvDeal* pDeal) :
	m_pDeal(pDeal)
{

}

CyDeal::~CyDeal()
{
}

bool CyDeal::isNone()
{ 
	return (NULL == m_pDeal); 
}

int CyDeal::getID() const
{
	return (m_pDeal ? m_pDeal->getID() : -1);
}

int CyDeal::getInitialGameTurn() const
{
	return (m_pDeal ? m_pDeal->getInitialGameTurn() : -1);
}

int CyDeal::getFirstPlayer() const
{
	return (m_pDeal ? m_pDeal->getFirstPlayer() : -1);
}

int CyDeal::getSecondPlayer() const
{
	return (m_pDeal ? m_pDeal->getSecondPlayer() : -1);
}

int CyDeal::getLengthFirstTrades() const
{
	return (m_pDeal ? m_pDeal->getLengthFirstTrades() : 0);
}

int CyDeal::getLengthSecondTrades() const
{
	return (m_pDeal ? m_pDeal->getLengthSecondTrades() : 0);
}

TradeData* CyDeal::getFirstTrade(int i) const
{
	if (i < getLengthFirstTrades() && NULL != m_pDeal && NULL != m_pDeal->getFirstTrades())
	{
		const CLinkList<TradeData>& listTradeData = *(m_pDeal->getFirstTrades());
		int iCount = 0;
		for (CLLNode<TradeData>* pNode = listTradeData.head(); NULL != pNode; pNode = listTradeData.next(pNode))
		{
			if (iCount == i)
			{
				return &(pNode->m_data);
			}
			iCount++;
		}
	}
	return (NULL);
}

TradeData* CyDeal::getSecondTrade(int i) const
{
	if (i < getLengthSecondTrades() && NULL != m_pDeal && NULL != m_pDeal->getSecondTrades())
	{
		const CLinkList<TradeData>& listTradeData = *(m_pDeal->getSecondTrades());
		int iCount = 0;
		for (CLLNode<TradeData>* pNode = listTradeData.head(); NULL != pNode; pNode = listTradeData.next(pNode))
		{
			if (iCount == i)
			{
				return &(pNode->m_data);
			}
			iCount++;
		}
	}
	return (NULL);
}

void CyDeal::kill()
{
	if (NULL != m_pDeal)
	{
		m_pDeal->kill();
	}
}

The "Cy" files are an interface between cpp and python. Nothing meaningful happens there. The file you want is CvDeal.cpp. Hopefully that will be a lot more interesting.
