Linux下的字符界面扫雷游戏
转载请注明出处。http://www.cnblogs.com/dave_cn/
这段时间事情比较忙，好不容易抽出些时间再找点游戏练练手，这里献丑了。
我在Ubuntu 10.04下测试过，可以正常运行。
代码用到了NCURSES库。编译的时候链一下ncurses库就可以了，如：
cc -Wall -O2 -o mine mine.c -lncurses
首先放出界面欣赏一下，眼晕的看看外面再继续 ==！：
代码：
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/wait.h>
#include <sys/select.h>
#include <time.h>
#include <signal.h>
#include <unistd.h>
#include <ncurses.h>
/* 雷区的范围 */
#define MINEAREA_WIDTH 9
#define MINEAREA_LENGTH 9
/* 雷的个数 */
#define MINE_NUMBER 10
/*
* 将每个方块的状态分类：
* 1.初始状态
* 2.判定为雷（也就是通常的插旗）
* 3.排除（若周边有n个雷则显示为n，0则显示为空，用-1来表示雷）
