在VS2010内使用MFC建立动画

在VS2010内使用MFC建立动画

1.导入4个位图图像到当前工程内，建立四个基础变量，

private: int m_moveY; int m_moveX; //移动距离 CBitmap m_bitmap[4]; //存储图像 int m_nCurBitmap; //索引

分别用于存储移动距离，存储图像，当前图像索引位置。

2.构造函数初始化：

CmyImage008View::CmyImage008View() { // TODO: add construction code here static int bitmap[]={IDB_BITMAP1,IDB_BITMAP2,IDB_BITMAP3,IDB_BITMAP4}; m_moveX=20; m_moveY=10; m_nCurBitmap=0; for(int i=0;i<4;i++) { m_bitmap[i].LoadBitmapW(bitmap[i]); } }

3.完成OnDraw()函数

void CmyImage008View::OnDraw(CDC *pDC ) { CmyImage008Doc* pDoc = GetDocument(); ASSERT_VALID(pDoc); /* if (!pDoc) return; */ CDC MDC; MDC.CreateCompatibleDC(pDC); CBitmap *pOldBitmap; BITMAP bm; pOldBitmap=(CBitmap*)MDC.SelectObject(&m_bitmap[m_nCurBitmap]); m_bitmap[m_nCurBitmap].GetBitmap(&bm); pDC->BitBlt(m_moveX,m_moveY,bm.bmWidth,bm.bmHeight,&MDC,0,0,SRCCOPY); MDC.SelectObject(pOldBitmap); MDC.DeleteDC(); // TODO: add draw code for native data here }

4.完成OnCreat函数

int CmyImage008View::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CView::OnCreate(lpCreateStruct) == -1) return -1; // TODO: Add your specialized creation code here //return 0; SetTimer(1,1000,NULL); }

5.完成OnTimer函数

void CmyImage008View::OnTimer(UINT_PTR nIDEvent) { // TODO: Add your message handler code here and/or call default CClientDC dc(this); m_nCurBitmap^=1; if(m_nCurBitmap>=2) { m_moveX+=10; if(m_moveX>300) m_nCurBitmap-=2; } else { m_moveX-=10; if(m_moveX<=10) m_nCurBitmap+=2; } OnDraw(&dc); InvalidateRect(NULL,TRUE); CView::OnTimer(nIDEvent); }

6.完成OnDestroy函数

void CmyImage008View::OnDestroy() { CView::OnDestroy(); KillTimer(1); // TODO: Add your message handler code here }

完成后的头文件为：

// myImage008View.h : interface of the CmyImage008View class//#pragma onceclass CmyImage008View : public CView{protected: // create from serialization only CmyImage008View(); DECLARE_DYNCREATE(CmyImage008View)// Attributespublic: CmyImage008Doc* GetDocument() const;// Operationspublic:// Overridespublic: virtual void OnDraw(CDC* pDC); // overridden to draw this view virtual BOOL PreCreateWindow(CREATESTRUCT& cs);protected: virtual BOOL OnPreparePrinting(CPrintInfo* pInfo); virtual void OnBeginPrinting(CDC* pDC, CPrintInfo* pInfo); virtual void OnEndPrinting(CDC* pDC, CPrintInfo* pInfo);// Implementationpublic: virtual ~CmyImage008View();#ifdef _DEBUG virtual void AssertValid() const; virtual void Dump(CDumpContext& dc) const;#endifprotected:// Generated message map functionsprotected: afx_msg void OnFilePrintPreview(); afx_msg void OnRButtonUp(UINT nFlags, CPoint point); afx_msg void OnContextMenu(CWnd* pWnd, CPoint point); DECLARE_MESSAGE_MAP()private: int m_moveY; int m_moveX; //移动距离 CBitmap m_bitmap[4]; //存储图像 int m_nCurBitmap; //索引public: afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct); afx_msg void OnTimer(UINT_PTR nIDEvent); afx_msg void OnDestroy();};#ifndef _DEBUG // debug version in myImage008View.cppinline CmyImage008Doc* CmyImage008View::GetDocument() const { return reinterpret_cast(m_pDocument); }#endif
