The minesweeper game is that the player enters a coordinate to determine whether the coordinate is a mine. If it is not a mine, it traverses the surrounding 8 coordinates. If there are several mines, it displays the number. If there are no mines in the 8 coordinates, then expand them all until until the coordinates become numbers.
1. Game Design Ideas
- Print menu for players to choose;
- Use two two-dimensional arrays to store the arranged mines and the detected mines;
- Use the function InitBoardo() function to initialize two arrays;
- Use the DispalyBoard() function to print the board;
- Use the SetMine() function to arrange mines;
- Use the FindMine() function to check for mines.
Second, the specific implementation
1. Using multiple files
- test.c file game framework
- game.c file game implementation
- game.h file game function declaration
2. Design of test.c file
- Design in the main function
The main function is the entry point of the entire program. Here I use it to write the entire framework of the game. The realization of the game is mainly realized by calling related functions in the main function.
int main()
{
int input = 0;
//用来生成随机值的,布置雷的使用使用
srand((unsigned int)time(NULL));
do
{
//打印菜单
meun();
printf("请进行选择:>");
scanf("%d", &input);
switch (input)
{
case 1:
//printf("扫雷\n");
game();
break;
case 0:
printf("退出游戏\n");
default:
printf("输入错误请重新输入\n");
break;
}
} while (input);
return 0;
}
- The design of the game() function
void game()
{
//布置雷的数组
char mine[ROWS][COLS];
//排查雷的数组
char show[ROWS][COLS];
//初始化数组
InitBoard(mine, ROWS, COLS,'0');
InitBoard(show, ROWS, COLS, '*');
//打印棋盘
//DispalyBoard(mine, ROW, COL);
DispalyBoard(show, ROW, COL);
//布置雷
SetMine(mine, ROW, COL);
//DispalyBoard(mine, ROW, COL);
//排查雷
FindMine(show, mine, ROW, COL);
}
The game function is mainly used to implement the logic of the game.
- Design of menu() function
void meun()
{
printf("******************************\n");
printf("******** 1.paly *******\n");
printf("******** 0.exit *******\n");
printf("******************************\n");
}
Mainly used for printing menus.
- overall result
#define _CRT_SECURE_NO_WARNINGS 1
#include "game.h"
void meun()
{
printf("******************************\n");
printf("******** 1.paly *******\n");
printf("******** 0.exit *******\n");
printf("******************************\n");
}
void game()
{
//布置雷的数组
char mine[ROWS][COLS];
//排查雷的数组
char show[ROWS][COLS];
//初始化数组
InitBoard(mine, ROWS, COLS,'0');
InitBoard(show, ROWS, COLS, '*');
//打印棋盘
//DispalyBoard(mine, ROW, COL);
DispalyBoard(show, ROW, COL);
//布置雷
SetMine(mine, ROW, COL);
//DispalyBoard(mine, ROW, COL);
//排查雷
FindMine(show, mine, ROW, COL);
}
int main()
{
int input = 0;
//用来生成随机值的,布置雷的使用使用
srand((unsigned int)time(NULL));
do
{
//打印菜单
meun();
printf("请进行选择:>");
scanf("%d", &input);
switch (input)
{
case 1:
//printf("扫雷\n");
game();
break;
case 0:
printf("退出游戏\n");
default:
printf("输入错误请重新输入\n");
break;
}
} while (input);
return 0;
}
3. Design of game.h file
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define ROW 9
#define COL 9
#define EASY_COUNT 10
#define ROWS ROW+2
#define COLS COL+2
//初始化数组
void InitBoard(char board[ROWS][COLS], int rows, int cols,char set);
//打印棋盘
void DispalyBoard(char board[ROWS][COLS], int row, int col);
//布置雷
void SetMine(char board[ROWS][COLS], int row, int col);
//排查雷
void FindMine(char show[ROWS][COLS], char mine[ROWS][COLS], int row, int col);
The purpose of this file is to declare functions.
4. Design of game.c file
- Initialize the array using the InitBoard function;
void InitBoard(char board[ROWS][COLS], int rows, int cols, char set)
{
int i = 0;
for (i = 0; i < rows; i++)
{
int j = 0;
for ( j = 0; j < cols; j++)
{
board[i][j] = set;
}
}
}
When passing parameters, pass the characters that need to be initialized into, which can avoid repeated codes.
- Use the DispalyBoard function to print the chessboard;
void DispalyBoard(char board[ROWS][COLS], int row, int col)
{
printf("*************扫雷游戏***********\n");
for (int i = 0; i <= col; i++)
{
printf("%d ", i);
}
printf("\n");
for (int i = 1; i <= row; i++)
{
printf("%d ", i);
for (int j = 1; j <= col; j++)
{
printf("%c ", board[i][j]);
}
printf("\n");
}
}
- Use the SetMine function to arrange mines;
void SetMine(char board[ROWS][COLS], int row, int col)
{
int x = 0;
int y = 0;
int count = EASY_COUNT;
while (count)
{
x = rand() % row + 1;
y = rand() % col + 1;
if (board[x][y] == '0')
{
board[x][y] = '1';
count--;
}
}
}
- Use the GetMineCount function to count how many mines are around the coordinates;
int GetMineCount(char mine[ROWS][COLS], int x, int y)
{
return
((mine[x - 1][y - 1]
+ mine[x - 1][y]
+ mine[x + 1][y + 1]
+ mine[x][y - 1]
+ mine[x][y + 1]
+ mine[x + 1][y - 1]
+ mine[x + 1][y]
+ mine[x][y + 1])
- (8 * '0'));
}
It is necessary to traverse the surrounding 8 coordinates and count the number of mines. Here I use the character 1 to arrange the mines. When the character 1 is subtracted from the character 0, the number 1 is obtained, so the 8 coordinates can be added and subtracted. 8 characters 0.
- Use the expand function to expand the security area;
void expand(char mine[ROWS][COLS], char show[ROWS][COLS], int x, int y, int* win)
{
if (x >= 1 && x <= ROW && y >= 1 && y <= COL)
{
int count = GetMineCount(mine, x, y);
if (count == 0)
{
//如果(x,y)坐标四周没有雷,将其改为空格,并且向四周扩散
show[x][y] = ' ';
int i = 0;
for (i = x - 1; i <= x + 1; i++)
{
int j = 0;
for (j = y - 1; j <= y + 1; j++)
{
//只对*进行递归,防止死循环
if (show[i][j] == '*')
{
expand(mine, show, i, j, win);
}
}
}
}
else //四周有雷显示雷数
{
show[x][y] = count + '0';
}
(*win)++;
}
}
Recursion is used so that the safe area can be expanded. If there are no thunder in the surrounding eight coordinates, the display is a blank space. As shown in the picture:
- Use the FindMine function to clear mines;
- Determine whether the coordinates are legal;
- Determine whether the coordinates are equal to character 1;
- Count the number of thunders around.
void FindMine(char show[ROWS][COLS], char mine[ROWS][COLS], int row, int col)
{
int x = 0;
int y = 0;
int win = 0;
while (win<row*col-EASY_COUNT)
{
printf("请输入坐标:>");
scanf("%d %d", &x, &y);
if (x >= 1 && y >= 1 && x <= row && y <= col)
{
if (mine[x][y] == '1')
{
printf("很遗憾你被炸死了。\n");
DispalyBoard(mine, ROW, COL);
break;
}
else
{
//该坐标不是雷,统计周围雷的个数
//int count = GetMineCount(mine, x, y);
//show[x][y] = count + '0';
expand(mine, show, x, y, &win);
DispalyBoard(show, ROW, COL);
//win++;
}
}
else
{
printf("请输入合法的坐标。\n");
}
}
if (win==row*col-EASY_COUNT)
{
printf("恭喜你,赢了!\n");
DispalyBoard(mine, ROW, COL);
}
}
