大家一起来，打地鼠
无聊编了个打地鼠的字符简易小游戏，与大家一起分享这个游戏需要 SDL 的支持，用 SDL 检测按键还有定时器确是比较方便阿（不过这个小游戏只用到了定时器）
还有一个小缺陷，因为是个简易版就懒得搞了，就是按键之后还得再按下回车，不过“有条件的同学”可以把 getchar 换成 getch 就 OK 了
还有 clear_screen，windows 下的同学需要修改一下 system ("cls");
小游戏，结构简单，不多说了，上代码
程序代码：
#include "stdlib.h"
#include "stdio.h"
#include "SDL2/SDL.h"
struct map
{
char state[3][3]; //state of every cave
};
struct map map = {{0, 0, 0, 0, 0, 0, 0, 0, 0}};
void clear_screen (void)
{
system ("clear"); //clear the screen, can't use gotoxy
}
void draw_map (struct map *map) //use pointer can save space
{
clear_screen ();
int i,j;
for (i=0; i<3; i++)
{
for (j=0; j<3; j++)
{
if ((*map).state[i][j]) //map[y][x]
{
printf ("%c ", '$'); //use $ represent mouse
}
else
{
printf ("%c ", '0');
}
}
printf ("\n");
}
}
void change_state (struct map *map, int pos) //pos range [0, 8]
{
int x, y;
x = pos%3;
y = pos/3;
(*map).state[y][x] = !(*map).state[y][x];
}
int get_state (struct map *map, int pos) //pos range [0, 8]
{
int x, y;
x = pos%3;
y = pos/3;
return (*map).state[y][x];
}
int judge (struct map *map)
{
int i,j;
for (i=0; i<3; i++)
{
for (j=0; j<3; j++)
{
if ((*map).state[i][j])
{
return 1;
}
}
}
return 0;
}
void over (void)
{
printf ("Game Over");
exit (0);
}
Uint32 SDL_callback (Uint32 interval, struct map *map)
{
if (judge(map))
{
over ();
}
else
{
change_state (map, rand()%9);
draw_map (map);
return interval;
}
}
/* change 7 8 9 to 1 2 3
* 4 5 6 4 5 6
* 1 2 3 7 8 9
*/
void change_key (int *key) //change the key to adapt the program
{
switch (*key)
{
case 7: *key=1; break;
case 8: *key=2; break;
case 9: *key=3; break;
case 1: *key=7; break;
case 2: *key=8; break;
case 3: *key=9; break;
}
}
int main (void)
{
int key;
SDL_TimerID timer;
SDL_Init (SDL_INIT_TIMER);
change_state (&map, rand()%9);
draw_map (&map);
timer = SDL_AddTimer (2000, (SDL_TimerCallback)SDL_callback, &map);
while (key = getchar ())
{
//handle the key
if ((key<'1') || (key>'9'))
{
continue;
}
key -= 0x30;
change_key (&key);
key -= 1;
if (get_state (&map, key))
{
change_state (&map, key);
draw_map (&map);
}
}
SDL_RemoveTimer (timer);
return 0;
}
不足之处，敬请指正
