内容简介

该程序是一款简易的扫雷小游戏，玩家开始游戏后，先初始化游戏棋盘，然后布置雷区，接着玩家根据提示输入坐标进行排雷操作，直到排除所有非雷区域或踩到雷结束游戏。

流程图

如图，该程序的不足是作为一款排雷游戏，其内容过于单一，只有一种模式，且没有计时功能，没有行列显示，用户选择时非常容易输错坐标，原代码中游戏界面比较简单，缺少美化和交互设计，玩家体验可能不够好。原代码没有成绩录入功能，玩家一次游玩后没有任何数据保存，无法让用户感受到每次游玩的不同与自身的进步

二次开发

针对以上问题，我为游戏增加了选择难度功能，计时功能，显示行列功能（有点没对齐=……=），把文件写入文件功能，可以为用户提供更好的游玩体验

选择难度功能，代码如下

点击查看代码

    int input = 0;
    srand((unsigned int)time(NULL));
    do
    {
        menu();
        cout << "请选择： ";
        cin >> input;
        switch (input)
        {
        case 1:
            cout << "选择难度级别：" << endl;
            cout << "1. 初级（10个雷，9x9棋盘）" << endl;
            cout << "2. 中级（20个雷，12x12棋盘）" << endl;
            cout << "3. 高级（30个雷，15x15棋盘）" << endl;
            int difficulty;
            cin >> difficulty;
            cout << "开始游戏" << endl;
            game(difficulty);
            break;
        case 0:
            cout << "退出游戏" << endl;
            break;
        default:
            cout << "选择错误。请重新选择" << endl;
            break;
        }
    } while (input);
    return 0;
}
void game(int difficulty)
{
    char lay_mine[16][16]; // 存放布雷信息
    char search_mine[16][16]; // 存放排查出雷的信息
    int size = 0;
    int num_mines = 0;
    if (difficulty == 1)
    {
        size = 9;
        num_mines = 10;
    }
    else if (difficulty == 2)
    {
        size = 12;
        num_mines = 20;
    }
    else if (difficulty == 3)
    {
        size = 15;
        num_mines = 30;
    }
    initialize_mineboard(lay_mine, '0', size);
    initialize_mineboard(search_mine, '*', size);
    print_mineboard(search_mine, size);
    set_laymine(lay_mine, num_mines);
    set_searchmine(lay_mine, search_mine, size, num_mines);
}

增加了计时功能，代码如下

点击查看代码

#include <chrono>
void set_searchmine(char lay_mine[][16], char search_mine[][16], int size, int num_mines)
{
    auto start = high_resolution_clock::now();
    int i = 0;
    int j = 0;
    int flag = 0;
    while (flag < size * size - num_mines)
    {
        cout << "请输入要排查的坐标：" << endl;
        cin >> i >> j;
        if ((i >= 1 && i <= size) && (j >= 1 && j <= size))
        {
            if (lay_mine[i][j] == 'X')
            {
                cout << "很遗憾，你所输入坐标为雷区，游戏失败！" << endl;
                print_mineboard(lay_mine, size);
                break;
            }
            else
            {
                search_mine[i][j] = mine_message(lay_mine, i, j) + '0';
                flag++;
                print_mineboard(search_mine, size);
            }
        }
        else
            cout << "输入坐标不合法，请重新输入" << endl;
    }
    auto stop = high_resolution_clock::now();
    auto duration = duration_cast<seconds>(stop - start);
    cout << "游戏结束，用时：" << duration.count() << " 秒" << endl;
    if (flag == size * size - num_mines)
    {
        cout << "恭喜你，排雷成功！" << endl;
        print_mineboard(lay_mine, size);
        record_score(duration.count(), true);
    }
    else
    {
        record_score(duration.count(), false);
    }
}

增加成绩录入功能

点击查看代码

#include<fstream>
void record_score(int time, bool success);
......
void record_score(int time, bool success)
{
    ofstream myfile("scores.txt", ios::app);
    if (myfile.is_open())
    {
        if (success)
        {
            myfile << "游戏成功，用时：" << time << " 秒" << endl;
        }
        else
        {
            myfile << "游戏失败，用时：" << time << " 秒" << endl;
        }
        myfile.close();
    }
    else
    {
        cout << "无法打开文件" << endl;
    }
}

心得

通过这次二次开发，我学习到开发小游戏除了要完成基本功能外，还要尽可能提高用户体验，游戏过于单一则游戏寿命不会长久，要有创新思想，为游戏增添新的功能以延长游戏寿命，要事先调查用户的需求，，了解用户想要哪些功能，以便更好的开发游戏，避免浪费时间做无用功。在修改代码时，要注意新增功能与之前的功能是否冲突，将代码分解为模块和函数，每个模块负责一个特定的功能，是个不错的避免错误发生的方法。
