C++实现基于控制台界面的吃豆子游戏

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
#define KEY_LEFT   WM_USER + 3
#define KEY_RIGHT   WM_USER + 4
//标识用户当前运动方向
#define DIRECTION_UP  WM_USER + 5
#define DIRECTION_DOWN  WM_USER + 6
#define DIRECTION_LEFT  WM_USER + 7
#define DIRECTION_RIGHT  WM_USER + 8
//标识要打印的元素类型
#define PRINT_WALL   WM_USER + 9
#define PRINT_FOOD   WM_USER + 10
#define PRINT_BODY   WM_USER + 11
#define PRINT_CLEAN   WM_USER + 12
#define KNOCK_WALL   WM_USER + 13
#define KNOCK_FOOD   WM_USER + 14

void Init(FOOD *pFood,WALL *pWall,BODY *pBody,HALL *pHall);
//进行一些初始化操作
void Print(POS *pos,int TYPE,int ix = 0);
//完成打印功能
void MakeWall(WALL *pWall);
//生成墙
void MakeFood(HALL *pHall,FOOD *pFood);
//生成食物
int Move(FOOD *pFood,WALL *pWall,BODY *pBody);
//用户移动
void ShowScore(BODY *pBody,FOOD *pFood);
//显示等级 和剩余豆子数
int IsOver(POS pos1,POS pos2,int TYPE);
//判断2点是否重合
int IsKnock(WALL *pWall,BODY *pBody,FOOD *pFood,int TYPE);
//判断是否撞墙、吃到豆子
int GetKey();
//得到用户按键
