引言

这是一个“泡泡消除”游戏。它包含通用的 CWnd

• CBubbleBreakerPanel
• CBubbleMovingTool
• CBubble2DArray
• CBubbleImageList
• CScene
• CUndoManager
• CBubbleSelector

背景

我喜欢 oopdreams software Inc. 开发的 WindowsCE 上的泡泡消除游戏，所以我想把它移植到 Windows XP 上，使用 MFC 实现。

Using the Code

CBubbleBreakerPanel 是从 CWnd 派生的，它是主要框架。它处理鼠标和键盘事件，以及 GDI 绘图等。

OnLButtonDown 是这样的

void CBubbleBreakerPanel::OnLButtonDown(UINT nFlags, CPoint point) 
{
	// TODO: Add your message handler code here and/or call default
	CWnd::OnLButtonDown(nFlags, point);
	if (m_rcNewGameZone.PtInRect(point)){
		NewScene(TRUE);
		Invalidate(FALSE);
		return;
	}
	else if (m_rcMenuZone.PtInRect(point)){
		if (m_Menu.GetSafeHmenu()){
			CMenu*pSubMenu = m_Menu.GetSubMenu(0);
			if (pSubMenu){
				ClientToScreen(&point);	
							}
		}
		return;
	}

void CBubbleBreakerPanel::DrawBubbleSelector(CDC*pDC)
{
	if (m_pBubbleSelector && (m_pBubbleSelector->GetCount() >= 2 ))
	{
		for(int iIndex = 0;iIndex<m_pBubbleSelector->GetCount();iIndex++){
			CBubble*pBubble = m_pBubbleSelector->GetAt(iIndex);
			if (pBubble->iState == BubbleSelected){
				CPen penBlack(PS_SOLID,1,COLOR_BLACK);
				(CPen*)pDC->SelectObject(&penBlack);
				
				CBubble*pLeftBubble = (pBubble->X - 1 >= 0) ? 
					&m_pBubbles[pBubble->Y*m_iXBubbleNums+
					pBubble->X-1] : NULL;
				CBubble*pRightBubble = (pBubble->X + 1 < 
					m_iXBubbleNums) ? &m_pBubbles
					[pBubble->Y*m_iXBubbleNums+pBubble->X+1] 
					: NULL;
				CBubble*pTopBubble = (pBubble->Y - 1 >= 0) ? 
					&m_pBubbles[(pBubble->Y-1)*
					m_iXBubbleNums+pBubble->X] : NULL;
				CBubble*pBottomBubble = (pBubble->Y + 1 < 
					m_iYBubbleNums) ? &m_pBubbles
					[(pBubble->Y+1)*m_iXBubbleNums+pBubble->X] 
					: NULL;
				
				int iPosX = pBubble->PosX + pBubble->OffsetX;
				int iPosY = pBubble->PosY + pBubble->OffsetY;
				
					if ((pLeftBubble == NULL) || 
					(pLeftBubble->iState != BubbleSelected)) {
					pDC->MoveTo(iPosX - pBubble->
					iRadius - 1,iPosY - pBubble->iRadius - 1);
					pDC->LineTo(iPosX - pBubble->
					iRadius - 1,iPosY + pBubble->iRadius + 1);
				}
				if ((pRightBubble == NULL) || 
					(pRightBubble->iState != BubbleSelected)){
					pDC->MoveTo(iPosX + pBubble->iRadius + 1,
						iPosY - pBubble->iRadius - 1);
					pDC->LineTo(iPosX + pBubble->iRadius + 1,
						iPosY + pBubble->iRadius + 1);
				}
				if ((pTopBubble == NULL) || (pTopBubble->iState 
						!= BubbleSelected)){
					pDC->MoveTo(iPosX - pBubble->
					iRadius - 1,iPosY - pBubble->iRadius - 1);
					pDC->LineTo(iPosX + pBubble->
					iRadius + 1,iPosY - pBubble->iRadius - 1);
				}
				if ((pBottomBubble == NULL) || (pBottomBubble->
						iState != BubbleSelected)){
					pDC->MoveTo(iPosX - pBubble->iRadius - 1,
						iPosY + pBubble->iRadius + 1);
					pDC->LineTo(iPosX + pBubble->iRadius + 1,
						iPosY + pBubble->iRadius + 1);
				}
			}
		}
	}
} 

CBubbleMovingTool 被设计用来处理泡泡的移动，而 CBubbleMovingToolH 是从 CBubbleMovingTool 派生出来的，用于处理水平移动，CBubbleMovingToolV 用于处理垂直移动，HCBubbleMovingToolVH 用于先处理水平移动，再处理垂直移动。

CBubbleMovingToolH::ReArrangeRow 是这样的

void CBubbleMovingToolH::ReArrangeRow(int iyIndex)
{
	if (m_pBubbles)
	{
		CBubble2DArray bubble2dArray(m_pBubbles,m_iXBubbleNums,m_iYBubbleNums);
		CBubble *pTempBubbles = new CBubble[m_iXBubbleNums];
		int ixValidCount = 0;

		if (pTempBubbles){ 
			for (int ixIndex = m_iXBubbleNums - 1;ixIndex >= 0;ixIndex--)
			{
				CBubble *pBubble = bubble2dArray.GetBubble
						(ixIndex,iyIndex);
				if (pBubble && (pBubble->iState == BubbleActive) )
				{
					pTempBubbles[ixValidCount].iColorIndex = 
							pBubble->iColorIndex;
					pTempBubbles[ixValidCount].iState = 
							pBubble->iState;
					ixValidCount++;
				}
			}

			for (int ixIndex = 0;ixIndex<m_iXBubbleNums;ixIndex++){
				CBubble *pBubble = bubble2dArray.GetBubble
							(ixIndex,iyIndex);
				pBubble->iState = BubbleNone;
			}
		}

		if (pTempBubbles)
		{
			
			for (int ixIndex = m_iXBubbleNums - 1 ,ixValidIndex = 0;
					ixValidIndex<ixValidCount;ixIndex--)
			{
				CBubble *pBubble = bubble2dArray.GetBubble
						(ixIndex,iyIndex);
				if (pBubble)
				{
					pBubble->iColorIndex = 
					pTempBubbles[ixValidIndex].iColorIndex;
					pBubble->iState = pTempBubbles
							[ixValidIndex].iState;
					ixValidIndex++;
				}
			}
			
			delete []pTempBubbles;
			pTempBubbles = NULL;
		}
	}
}

CBubbleSelector 被设计用来处理泡泡的选择。

CBubbleSelector PtInSelector 是这样的

BOOL CBubbleSelector::PtInSelector(CPoint point)
{
    BOOL bFounded = FALSE;
    if (GetCount() >= 2)
    {
        for(int iIndex = 0;iIndex<GetCount();iIndex++)
        {
            CBubble*pBubble = GetAt(iIndex);
            if (pBubble)
            {
                CRect rcBubbble = pBubble->GetRect();
                rcBubbble.InflateRect(1,1,1,1);
                if (rcBubbble.PtInRect(point)){
                    bFounded = TRUE;// Action
                }
            }
        }
    }

    return bFounded;
}

关注点

我计划为其提供完整的 GDI+ 支持来进行绘图。

我也计划确保它在 Windows 平台上完美运行。
