现代软件工程课程设计——黄金点游戏

 

 

一. 课设要求

　　1. 游戏基本规则：N个同学（N通常大于10），每人写一个0~100之间的有理数(不包括0或100)，交给裁判，裁判算出所有数字的平均值，然后乘以0.618(所谓黄金分割常数），得到G值。提交的数字最靠近G（取绝对值）的同学得到N分，离G最远的同学得到－2分，其他同学得0分。

　　2. 采用单机方式实现，需要为用户提供便利的输入界面。

　　3. 该游戏每次至少可以运行10轮以上，并能够保留各轮比赛结果。

　　4. 后续在此基础上迭代开发。

 

 

 

二. 相关资料

　　1. 结对编程和两人合作：https://www.cnblogs.com/xinz/archive/2011/08/07/2130332.html

　　2. 创新的时机——黄金点游戏：https://www.cnblogs.com/xinz/archive/2011/08/08/2130505.html

 

 

三. 开发环境

　　系统为win10，项目拟采用 java 语言编写，集成环境为 IntelliJ IDEA。交互界面用 java swing 界面编写。

 

四. 思路

　　首先理解该程序的逻辑，将各个部分封装并且建立联系。其次对该程序进行编写，并且测试数据。最后添加可视化界面。

 

五. 程序大致流程图

 

六. 命令行程序代码及展示

　　1. 代码实现（c++）

　　　　1.1. 游戏大类

class Gold_point{
    public:
        Gold_point();
        ~Gold_point();
        void Show_history();  // 历史分数
        void Show_result();  // 显示结果
        void Welcome();  // 欢迎界面
        void Gaming();  // 进行游戏
        void Name_input();  // 输入姓名
        int player_num, round_num, now_round_num = 1;  // 分别为玩家人数、游戏总轮数、当前所在轮数
        double now_result = 0;  // 即时结果
        int point_choice[10000];  // 每一轮每人的分数选择
        vector<vector<int> > history_scores;  // 存储历史分数
        double now_distance[10000];  // 存储每一轮每位玩家到黄金点的距离
        vector<double> round_distance;  // 距离复用
　　　　　　 // 玩家的结构体数组
        struct Player{
            string name;
            int scores, index;  // 分数和身份id
        }player[10000];
        
};

 

 　　　　1.2. 姓名输入

void Gold_point::Name_input(){
    for(int i = 0; i < player_num; i++){
        cout << "请输入 " << i + 1 << " 号玩家的姓名：" ;
        cin >> player[i].name;
    }    
}

　　　　1.3. 历史成绩

void Gold_point::Show_history(){
    for(;;){
        cout << "您想要查看历史的每轮成绩吗？Y / N：";
        char choice;
        cin >> choice;
        if(choice == 'Y' || choice == 'y'){
            cout << "您想查看第几轮的成绩？输入数字则查看指定轮成绩，输入 0 则查看全部历史成绩：";
            int tempNum;
            cin >> tempNum;
            if(tempNum == 0){
                for(int i = 0; i < history_scores.size(); i++){
                    cout << "第 " << i + 1 << " 轮的成绩是:" << endl;
                    for(int j = 0; j < player_num; j++)    cout << player[j].name << "：" << history_scores[i][j] << endl;
                }
            }else if(tempNum >= 1 && tempNum <= history_scores.size()){
                cout << "第 " << tempNum << " 轮的成绩是：" << endl;
                for(int j = 0; j < player_num; j++)    cout << player[j].name << "：" << history_scores[tempNum - 1][j] << endl;
            }else{
                cout << "输入数据有误！";
            }
            cout << "是否继续？Y / N：";
            cin >> choice;
            if(choice == 'Y' || choice == 'y')    continue;
            else    return; 
        }
        return;
    }
}

 

　　　　1.4. 游戏主程序

void Gold_point::Show_history(){
    for(;;){
        cout << "您想要查看历史的每轮成绩吗？Y / N：";
        char choice;
        cin >> choice;
        if(choice == 'Y' || choice == 'y'){
            cout << "您想查看第几轮的成绩？输入数字则查看指定轮成绩，输入 0 则查看全部历史成绩：";
            int tempNum;
            cin >> tempNum;
            if(tempNum == 0){
                for(int i = 0; i < history_scores.size(); i++){
                    cout << "第 " << i + 1 << " 轮的成绩是:" << endl;
                    for(int j = 0; j < player_num; j++)    cout << player[j].name << "：" << history_scores[i][j] << endl;
                }
            }else if(tempNum >= 1 && tempNum <= history_scores.size()){
                cout << "第 " << tempNum << " 轮的成绩是：" << endl;
                for(int j = 0; j < player_num; j++)    cout << player[j].name << "：" << history_scores[tempNum - 1][j] << endl;
            }else{
                cout << "输入数据有误！";
            }
            cout << "是否继续？Y / N：";
            cin >> choice;
            if(choice == 'Y' || choice == 'y')    continue;
            else    return; 
        }
        return;
    }
}
