在上一篇文章当中我介绍了一个走迷宫的写法,但是那个迷宫没什么可玩性和趣味性,所以我打算在迷宫的基础上加上一个推箱子,使之有更好的操作空间,从而增强了游戏的可玩性和趣味性。
void menu()
{
printf("|---------------------------------------|\n");
printf("| |\n");
printf("| 走迷宫 |\n");
printf("| 1.Start |\n");
printf("| 2.Exit |\n");
printf("| e.Restart |\n");
printf("| |\n");
printf("|---------------------------------------|\n");
}
int main()
{
int input = 0;
do
{
menu();
printf("请选择:");
scanf("%d", &input);
switch (input)
{
case 1:
game();
break;
case 0:
printf("退出游戏!\n");
break;
default:
printf("选择有误,请重新选择!\a\n");
}
} while (input);
}
迷宫的组成要素无非就是:墙、路、入口、出口,根据这些要素我们可以设置一个数组然后随机给其赋值为0,1,2,3,当数组等于0时打印路(这里用空格代替),等于1时打印墙(这里用█代替),等于2打印入口(这里用S代替),等于3时打印出口(这里用E代替)。
因为这些要素的生成都与随机数有关,所以这里就要使用到time函数、srand函数和rand函数来进行随机数的生成。
#include<time.h>
srand((time(NULL))
int x = rand();
给数组初始化为0生成路,后面再用随机数生成。
for (int i = 0; i < SIZE; i++)
{
for (int j = 0; j < SIZE; j++)
{
maze[i][j] = 0;
}
}
还需要设置围墙将我们的迷宫围起来,防止数组的越界访问。
for (int i = 0; i < SIZE; i++)
{
maze[0][i] = 1;
maze[i][0] = 1;
maze[SIZE - 1][i] = 1;
maze[i][SIZE - 1] = 1;
}
因为入口、出口和箱子(我在这里只设置了一个)都是只有一个,所以这里我们需要单独使用随机数生成入口、出口和箱子。
//设置入口
int start_x = rand() % SIZE;
int start_y = rand() % SIZE;
maze[start_y][start_x] = 2;
//设置出口
int end_x = rand() % SIZE;
int end_y = rand() % SIZE;
maze[end_y][end_x] = 3;
//设置箱子
int box_x = rand() % SIZE;
int box_y = rand() % SIZE;
maze[box_y][box_x] = 4;
这里使用了goto语句
3.4.1 防止入口和出口出现在围墙上
again:
//防止入口或出口出现在围墙上
if (start_x == 0 || start_x == SIZE - 1 || start_y == 0 || start_y == SIZE - 1
|| end_x == 0 || end_x == SIZE - 1 || end_y == 0 || end_y == SIZE - 1
|| box_x == 0 || box_x == SIZE - 1 || box_y == 0 || box_y == SIZE - 1)
goto again;
3.41 防止箱子出现在围墙的边上
因为如果箱子出现在边上,这个箱子就推不了左右了。所以需要防止箱子出现在围墙的边上
again:
//防止箱子出现在边上
if (box_y == 1 || box_y == SIZE || box_x == 1 || box_x == SIZE)
goto again;
for (int i = 0; i < SIZE; i++)
{
for (int j = 0; j < SIZE; j++)
{
if (maze[i][j] != 2 && maze[i][j] != 3)
{
if (rand() % 4 == 0)
{
maze[i][j] = 1;
}
}
}
}
在这里用到了getch()函数,这个函数需要用#include <conio.h>来进行调用。
#include <conio.h>
int main()
{
while (1)
{
int x = getch();
if (x == 'w')
printf("上\n");
if (x == 'a')
printf("左\n");
if (x == 's')
printf("下\n");
if (x == 'd')
printf("右\n");
}
return 0;
}
输入w向上移动,输入s向下移动,输入a向左移动,输入d向右移动。
以输入w向上移动为例:
需要满足S的上一个格子是路,也就是需要满足maze[start_y - 1][start_x] == 0才会接受向上移动的信息,而要想实现一个向上移动的效果,我们就需要将原来的位置变为路也就是使maze[start_y][start_x] = 0;,然后使原来位置的上一个变为S也就是?start_y--; maze[start_y][start_x] = 2;
完整的移动代码:?
if (x == 'w')//上
{
if (maze[start_y - 1][start_x] == 0)
{
maze[start_y][start_x] = 0;
start_y--;
maze[start_y][start_x] = 2;
}
}
其中system("cls")函数的作用是清屏,它需要使用#icnldue<stdlib.h>进行调用。?
以向上移动为例:
箱子可以向上移动的前提是:
1.箱子出现在S的上面,也就是maze[start_y - 1][start_x] == 4
2.箱子的上面不是墙,也就是maze[box_y - 1][box_x] != 1
实现一个向上移动的效果:
实现这个移动效果的写法与移动S的写法相同
if (x == 'w')//上
{
if (maze[start_y - 1][start_x] == 4)
{
if (maze[box_y - 1][box_x] != 1)
{
maze[box_y][box_x] = 0;
box_y--;
maze[box_y][box_x] = 4;
}
}
do
{
system("cls");
print_maze(maze);
int x = getch();
if (x == 'w')//上
{
if (maze[start_y - 1][start_x] == 4)
{
if (maze[box_y - 1][box_x] != 1)
{
maze[box_y][box_x] = 0;
box_y--;
maze[box_y][box_x] = 4;
}
}
if (maze[start_y - 1][start_x] != 1 && maze[start_y - 1][start_x] != 4&& maze[start_y - 1][start_x] != 3)
{
maze[start_y][start_x] = 0;
start_y--;
maze[start_y][start_x] = 2;
}
}
if (x == 'a')//左
{
if (maze[start_y][start_x - 1] == 4)
{
if (maze[box_y][box_x - 1] != 1)

maze[box_y][box_x] = 0;

{
maze[start_y][start_x] = 0;
start_x--;
maze[start_y][start_x] = 2;
}
}
if (x == 's')//下
{
if (maze[start_y + 1][start_x] == 4)
{
if (maze[box_y + 1][box_x] != 1)
{
maze[box_y][box_x] = 0;
box_y++;
maze[box_y][box_x] = 4;
}
}
if (maze[start_y + 1][start_x] != 1 && maze[start_y + 1][start_x] != 4 && maze[start_y + 1][start_x] != 3)
{
maze[start_y][start_x] = 0;
start_y++;
maze[start_y][start_x] = 2;
}
}
if (x == 'd')//右
{
if (maze[start_y][start_x + 1] == 4)
{
if (maze[box_y][box_x + 1] != 1)
{
maze[box_y][box_x] = 0;
box_x++;
maze[box_y][box_x] = 4;
}
}
if (maze[start_y][start_x + 1] != 1&& maze[start_y][start_x + 1] != 4 && maze[start_y][start_x + 1] != 3)
{
maze[start_y][start_x] = 0;
start_x++;
maze[start_y][start_x] = 2;
}
}
} while (1);
其中system("cls")函数的作用是清屏,它需要使用#icnldue<stdlib.h>进行调用。?
当门的位置等于箱子也就是maze[end_y][end_x] == 4即为通关成功。
加一个e的指令重开游戏
if (x == 'e')
{
system("cls");
printf("重新开始游戏!\n");
break;
