迷宫小游戏

想法：设计一个迷宫，走出迷宫，获得奖励。

思路：

1.首先要有个游戏开始界面，主要就是显示一些东西。

    printf("\n\t\t\t");
    for(int i = 0;i < 20;i ++){
        printf("-");  //输出界面上界
    }
    printf("\n");
    printf("The * is the symbol of you.\n");  //*表示你所处的位置
    printf("You can press (up,down,left,right) to move the (*).\n");  //你可以按上、下、左右键控制移动
    printf("If your keyboard doesn't have these buttons,you can also press (w,s,a,d) to move the (*).\n");  //也可以按w/s/a/d控制移动
    printf("Please press Enter to enter the maze.\n");  //请按回车键进入游戏界面
    getch();  //don't show in the screen,不回显
    system("cls");  //清屏

2.画迷宫。4表示*，输出*；0表示道路，输出空格；1表示墙，输出#。在这之前要对迷宫数组进行初始化，这里我用的迷宫数组是参照的网上的一个。

            int maze[20][20] = {{1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1},
		                {4,0,0,0,0,1,1,1,0,0,0,0,1,1,1,0,0,0,0,1},
		                {1,1,1,0,0,1,1,1,0,0,1,0,0,0,0,0,1,0,0,1},
		                {1,1,1,0,0,1,1,1,0,0,1,1,1,1,0,0,1,0,0,1},
		                {1,0,0,0,0,1,1,1,0,0,0,1,1,1,0,0,1,0,0,1},
		                {1,0,0,1,1,1,1,1,1,0,0,1,1,1,0,0,1,0,0,1},
		                {1,0,0,1,1,1,1,1,1,0,0,1,0,0,0,0,1,0,0,1},
		                {1,0,0,0,0,0,0,0,0,0,0,1,0,0,1,1,1,0,0,1},
		                {1,0,0,0,0,0,0,0,0,0,0,1,0,0,1,1,1,0,0,1},
		                {1,0,0,1,1,1,1,1,1,0,0,0,0,0,1,0,0,0,0,1},
		                {1,0,0,0,0,0,0,1,1,0,0,0,0,0,1,0,0,1,1,1},
		                {1,0,0,0,0,0,0,1,1,0,0,1,1,1,1,0,0,1,1,1},
		                {1,1,1,1,1,0,0,1,1,0,0,0,0,0,0,0,0,0,0,1},
		                {1,1,1,1,1,0,0,1,1,1,1,1,0,0,0,0,0,0,0,1},
		                {1,0,0,0,0,0,0,1,0,0,0,1,1,1,1,0,1,0,0,1},
		                {1,0,0,0,0,0,0,1,0,0,0,0,0,0,0,1,1,0,0,1},
		                {1,0,0,1,1,1,1,1,0,1,1,1,1,0,0,0,0,0,1,1},
		                {1,0,0,0,0,0,0,0,0,0,0,0,1,0,0,0,0,1,1,1},
		                {1,1,1,1,1,1,1,1,1,1,0,0,1,1,1,0,0,0,0,0},
		                {1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1}};

把迷宫打印出来：

//画迷宫
void draw(int maze[20][20]){
    int i,j;
    for(i = 0;i < 20;i ++){
        printf("\t\t\t");                          //display int the center of the screen
        for(j = 0;j < 20;j ++){
            if(maze[i][j] == 4) printf("*");       //4---you
            else if(maze[i][j] == 0) printf(" ");  //0---road
            else printf("#");                      //1---wall
        }
        printf("\n");
    }
}

3.移动。

初始化a和b，a表示*所在的行坐标，b表示*所在的列坐标。用了do while循环。每次用getch()读入一个按键，然后判断*当前位置的上下左右四个位置，如果不是1，表示不是墙，有路可以走，记得要break。这里有一个注意点，就是判断完一个if之后，如果不符合条件，是不会break的，因为用的是switch，所以如果对应到case，不符合条件，会跳到下一个if，所以会出现“下边是墙，然后你按→键会神奇地出现往左移的情况”。为了避免这种情况，所以要在if外面再加个break，这样就好啦。每移动一次，就用cls清一下屏。最后*如果出现在迷宫出口，就表示成功，退出并且输出“儿童节快乐”。

//移动
void move(int maze[20][20]){
    int a = 1;  //row
    int b = 0;  //col
    char num;
    do{
        num = getch();
        //only change four locations of *
        switch(num){
            case 72:  //↑的ASCII
            case 87:  //大写W的ASCII
            case 119: //小写w的ASCII
            if(maze[a-1][b] != 1){  //up
                swap(maze[a][b],maze[a-1][b]);
                a --;
                system("cls");  //clear the screen
                draw(maze);
                break;
            }
            break;
            case 80:
            case 83:
            case 115:
            if(maze[a+1][b] != 1){  //down
                swap(maze[a+1][b],maze[a][b]);
                a ++;
                system("cls");
                draw(maze);
                break;
            }
            break;
            case 75:
            case 65:
            case 97:
            if(maze[a][b-1] != 1){  //left
                swap(maze[a][b-1],maze[a][b]);
                b --;
                system("cls");
                draw(maze);
                break;
            }
            break;
            case 77:
            case 68:
            case 100:
            if(maze[a][b+1] != 1){  //right
                swap(maze[a][b+1],maze[a][b]);
                b ++;
                system("cls");
                draw(maze);
                break;
            }
            break;
            default:break;
        }
        if(maze[18][19] == 4){
            printf("\n\t\t    Happy Children's Day to You!\n\n\n");
            Sleep(2000);  //delay
            break;
        }
    }while(1);
}

4.这里我还美化了一下程序，改了界面的字体颜色，插入了一个BGM。

改字体：我看的百度经验用了一行代码

system("color 0D");  //color

插入BGM：BGM要和exe文件放在同一个文件夹里，另外，PlaySound函数只支持wav,我用mp3试了半天没成功。

PlaySound("1.wav",NULL,SND_FILENAME|SND_ASYNC|SND_LOOP);

5.最后两个注意点：

一：编译的时候，要进行链接，因为用到了winmm文件，所以要链接。打开菜单栏“项目”选项，选择“构建选项”，进入界面，选择链接器设置，添加winmm进行链接。

二：本着送给同学作为儿童节礼物，结果把exe和BGM，还有使用说明压缩打包发给同学，反映打不开，说缺少dll文件(有些同学不学编程，电脑里没编程软件)。

上网查了一下，说要进行静态链接，-static-libgcc。但是我用Code Blocks进行链接器设置的时候，一直没成功，不知道为啥。觉得要凉了。突然灵机一动，把dll文件也发给他们不就好了嘛。于是加进打包文件里，果然成功了。

#include<stdlib.h>
#include<conio.h>               //get the ASCII of up, down, left and right
#include<windows.h>
#include<mmsystem.h>
#pragma comment(lib,"winmm.lib") //PlaySound()
#include<time.h>
#include<algorithm>
using namespace std;

            if(maze[i][j] == 4) printf("*");       //4---you
            else if(maze[i][j] == 0) printf(" ");  //0---road
            else printf("#");                      //1---wall
