本文实例讲述了C++实现基于控制台界面的吃豆子游戏。分享给大家供大家参考。具体分析如下：
程序运行界面如下所示：
ESC键可退出游戏。
main.cpp源文件如下：
#include "lib.h"
#pragma once
extern int level;
int main()
{
FOOD food;
WALL wall;
BODY CurPos;
HALL hall;
int iExit = 0;
while(1)
{
if(iExit)
break;
Init(&food,&wall,&CurPos,&hall);
MakeWall(&wall);
while(1)
{
Sleep(200);
int res = Move(&food,&wall,&CurPos);
if(1 == res) //重新开局
break;
else if(-1 == res) //用户退出
{
iExit = 1;
break;
}
ShowScore(&CurPos,&food);
}
}
return 0;
}
lib.h头文件如下：
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <time.h>
//标识用户按下的方向键
#define KEY_UP WM_USER + 1
#define KEY_DOWN WM_USER + 2
