c++实现经典游戏贪吃蛇（超详解) c++实现经典游戏贪吃蛇（超详解) 要求： 1碰到四周和自身游戏结束； 2迟到食物蛇身增长； 3食物吃得越多游戏越快； 4通过w,a,s,d可控制蛇头的方向； 5蛇身颜色不一致。源码（需要easy-x) 阅读详情

希望对C++初学者了解OOP有一定的帮助，本人也是菜鸟欢迎批评指教。

废话少说，上代码：

#ifndef SNAKE_H_
#define SNAKE_H_
#include <deque>
#include <iostream>
#include "windows.h"
#include <string>
using namespace std;
typedef struct
{
	int xPos;
	int yPos;
    int derect;//方向0、1、2、3依次表示左\右\上\下
}MPOINT;
//class _declspec(dllexport) snake
class snake
{
public:
	MPOINT ptHead;
	MPOINT ptTail;
public:
	deque<MPOINT> que;
	MPOINT GetHeadPt()const;
	MPOINT GetTailPt()const;
private:
	int headDerect;
	int tailDerect;
	int length;
	bool IsMoving;
	void SetTailPos();//根据蛇头位置确定蛇尾位置
public:
	snake();
	snake(MPOINT& pt,int& len);
	virtual ~snake();
	void AddLength(int& num);
	void SetMoveDerection(int& flag);
	bool StartMove();
	bool StopMove();
	bool IsSnakeMoving()const;
	MPOINT GetHeadPos()const;
	MPOINT GetTailPos()const;
	void ShowSnake()const;
	string GetPointDerection(const MPOINT& pt)const;
	//移动左边点pt,len为移动的距离,ret默认为true即移动方向与点的运动方向相同
	void MovePoint(MPOINT& pt,int len=1,bool ret=true);
	//unsigned int timerid;
private:
	HANDLE hThread;
};
#endif;

由于是在控制台应用程序上试运行，就添加了一个线程函数：

#include "stdafx.h"
#include "snake.h"
#include "stdio.h"
#include "conio.h"
bool operator==(MPOINT& pt1,MPOINT& pt2)
	{
		if((pt1.xPos==pt2.xPos)&&(pt1.yPos==pt2.yPos))
			return true;
		return false;
	}
//int count=0;
UINT timerid;
UINT Thread(PVOID   pvoid)  
{  
	snake* pSnake=(snake*)pvoid;
    MSG   msg;  
    PeekMessage(&msg,   NULL,   WM_USER,   WM_USER,   PM_NOREMOVE);   
	timerid=SetTimer(NULL,111,500,NULL); 
    BOOL   bRet;  
    int   count   =0;  
    while(   (bRet   =   GetMessage(   &msg,   NULL,   0,   0   ))   !=   0)  
    {    
        if   (bRet   ==   -1)  
        {  
            //   handle   the   error   and   possibly   exit  
        }  
        else  
            if(msg.message==WM_TIMER)  
            {  
				if(pSnake->IsSnakeMoving())
				{
					//MessageBox(NULL,_T("FFT"),_T("ffff"),MB_YESNO);
					pSnake->MovePoint(pSnake->ptHead);//->GetHeadPos());
					pSnake->MovePoint(pSnake->ptTail);//GetTailPos());
					int count=pSnake->que.size();
					if(count)
					{
						MPOINT pt=pSnake->que.at(count-1);
						if(pSnake->GetTailPos()==pt)
							pSnake->que.pop_back();
					}
				}
				cout<<endl;
				pSnake->ShowSnake();
				//else
					//KillTimer(NULL,timerid);
            }  
            else  
            {  
                TranslateMessage(&msg);    
                DispatchMessage(&msg);    
            }  
    }

    return   0;

如果需要实现贪吃蛇游戏的话，可以用MFC做个框架，然后添加这两个文件，对相应的键盘按键进行处理，输赢处理……

也是很容易的。
