该程序的图片资源是借用网上一位大神的

1.建立一个基于对话框的程序，命名为parkour

使用智能指针需包含头文件memory

2.添加类CCharacter和CScene

#pragma once
    
    #include<vector>
    
    using std::vector;
    
    class CCharacter
    {
    public:
    	CCharacter();
    	~CCharacter();
    private:
    	static const int ELEVATION = 20;//背景土地高度
    	static const int MAXFRAME = 16;//人物奔跑有16幅画面
    	
    private:
    	Rect m_rect;//绘图位置
    	int m_curFrame;
    	vector<std::shared_ptr<Image>>m_imgCharacter;
    	void MoveFront(Rect rc);//前进
    	void NextFrame();//下一帧
    public:
    	void DrawCharacter(Graphics& gh,Rect rc);
    };

#include "stdafx.h"
    #include "Character.h"
    
    
    CCharacter::CCharacter()
    {
    	
    	CString path;
    
    	for (int i = 1; i <= MAXFRAME; i++)
    	{
    		path.Format(_T("res\\%d.png"), i);
    		m_imgCharacter.push_back(std::shared_ptr<Image>(Image::FromFile(path)));
    	}
    
    	m_rect.Width = m_imgCharacter[0]->GetWidth();
    	m_rect.Height = m_imgCharacter[0]->GetHeight();
    	m_rect.X = 0;
    
    	m_curFrame = 0;
    }
    
    
    CCharacter::~CCharacter()
    {
    }
    
    
    
    void CCharacter::MoveFront(Rect rc)
    {//人运动到中心不再运动
    	int  border = (rc.Width - m_rect.Width) / 2;
    	if (m_rect.X <= border)
    		m_rect.X += 4;
    }
    
    void CCharacter::NextFrame()
    {
    	m_curFrame++;
    	if (m_curFrame == MAXFRAME)
    	{
    		m_curFrame = 0;
    	}
    
    }
    
    void CCharacter::DrawCharacter(Graphics& gh,Rect rc)
    {
    	m_rect.Y = rc.Height - ELEVATION-m_rect.Height;
    	gh.DrawImage(m_imgCharacter[m_curFrame].get(), m_rect);
    	NextFrame();
    	MoveFront(rc);
    }

#pragma once
    class CScenee
    {
    public:
    	CScenee();
    	~CScenee();
    private:
    	std::shared_ptr<Image>m_imgStt;//起始背景
    	std::shared_ptr<Image>m_imgNxt;//滚动背景
    	int m_bgX;//起始x坐标
    	bool m_isStart;
    	void MoveBg();//背景移动
    public:
    	void DrawScene(Graphics& gh,Rect rc);
    	
    };

#include "stdafx.h"
    #include "Scenee.h"
    
    
    CScenee::CScenee()
    {
    	m_imgStt = std::shared_ptr<Image>(Image::FromFile(_T("res\\bgStart.jpg")));
    	m_imgNxt = std::shared_ptr<Image>(Image::FromFile(_T("res\\bgNext.jpg")));
    	if (!m_imgStt&&!m_imgNxt)
    	{
    		return ;
    	}
    	m_isStart = true;
    	m_bgX = 0;
    }
    
    
    CScenee::~CScenee()
    {
    }
    
    
    
    void CScenee::MoveBg()
    {
    	m_bgX -= 6;
    }
    
    void CScenee::DrawScene(Graphics& gh, Rect rc)
    {
    	MoveBg();
    	if (m_bgX <= -rc.Width)
    	{
    		m_bgX = 0;
    		if(m_isStart)
    		{
    			m_isStart = false;
    		}
    	}
    
    	rc.X = m_bgX;
    
    	if (m_isStart)
    	{
    		gh.DrawImage(m_imgStt.get(), rc);
    	}
    	else
    	{
    		gh.DrawImage(m_imgNxt.get(), rc);
    	}
    
    	rc.X += rc.Width;
    	
    	gh.DrawImage(m_imgNxt.get(), rc);
    }

背景是用两张图拼接起来的

3.在对话框类中添加私有成员

private:
    	Rect rc;
    	void Draw();
    	CCharacter m_character;
    	CScenee m_scenee;

初始化中添加如下代码

CRect rect;
    	GetClientRect(&rect);
    	rc.X = rect.left;
    	rc.Y = rect.top;
    	rc.Width = rect.Width();
    	rc.Height = rect.Height();
    
    	SetTimer(1, 10, NULL);

添加WM\_TIMER和Draw（）函数

void CparkourDlg::OnTimer(UINT_PTR nIDEvent)
    {
    	// TODO: 在此添加消息处理程序代码和/或调用默认值
    	Draw();
    	CDialogEx::OnTimer(nIDEvent);
    }

void CparkourDlg::Draw()
    {
    	HDC hdc = ::GetDC(GetSafeHwnd());
    	CDC* pDC = CClientDC::FromHandle(hdc);//获取窗口DC  
    	CDC m_dcMemory;//缓冲DC  
    	CBitmap bmp;//缓冲位图  
    	bmp.CreateCompatibleBitmap(pDC, rc.Width, rc.Height);//创建位图  
    	m_dcMemory.CreateCompatibleDC(pDC);//缓冲DC初始化  
    	CBitmap* pOldBitmap = m_dcMemory.SelectObject(&bmp);//将位图和缓存DC关联  
    														//gdi+绘图  
    	Graphics gh(m_dcMemory.GetSafeHdc());
    
    	//绘图代码  
    	{
    		m_scenee.DrawScene(gh,rc);
    		
    		m_character.DrawCharacter(gh,rc);
    		
    	
    
    	}
    	::BitBlt(hdc, 0, 0, rc.Width, rc.Height, m_dcMemory.GetSafeHdc(), 0, 0, SRCCOPY);//将缓存DC的内容复制到屏幕  
    	pDC->DeleteDC();
    	m_dcMemory.SelectObject(pOldBitmap);
    	ReleaseDC(&m_dcMemory);
    	DeleteObject(bmp);
    }

4.添加WM\_NCHITEST消息

LRESULT CparkourDlg::OnNcHitTest(CPoint point)
    {
    	// TODO: 在此添加消息处理程序代码和/或调用默认值
    
    	return HTCAPTION;
    }

做出来的效果如下
