Question

我创建了一个用户可以玩石头剪刀的程序。

我希望能够做的事情之一就是询问用户是否想再次玩游戏，如果他们重新开始游戏，如果不重新开始，那么它就会结束。

我有所有设置功能，我在类＃34; MainClass＆＃34;（playAgainn是函数名称）中的while循环之后调用该函数但由于某种原因它不被调用并且程序最后列出CPU和播放器的分数，然后按Enter键不做任何事情，这样程序就会保持打开状态。

有谁知道这是为什么或如何更改我的代码，以便我能够根据＆＃34; y＆＃34;的用户输入循环程序。或＆＃34; n＆＃34; - 非常感谢帮助。如果有帮助，我使用Microsoft Visual Studio社区2015在C＃中编码。该守则列于下方。

Answer 1

您需要将RPS.playAgainn(); 向上移动进入其上方的循环。

然后mainClass将如下所示：

class MainClass
{
    public static void Main(string[] args)
    {
        while (RPS.playAgain)
        {
            while (RPS.scorePlayer < 3 && RPS.scoreCPU < 3)
            {
                RPS.userInput();
                RPS.CheckWhoWinsEach();
                RPS.CheckWhoWon();
            }
            RPS.playAgainn();
        }
    }
}

Answer 2

你的循环中有几个问题。

您应该检查并在外部while循环内设置playAgain。
当用户选择y时，您应该重置分数。

再次播放

public static void playAgainn()
{
    Console.WriteLine("Do you want to play again?(y/n)");
    string loop = Console.ReadLine();
    if (loop == "y")
    {
        playAgain = true;
        // reset scores here
        Console.Clear();
    }
    else if (loop == "n")
    {
        playAgain = false;
    }
    else
    {

    }
}

主要班级

class MainClass
{
  public static void Main(string[] args)
  {
      while (RPS.playAgain)
      {
          while (RPS.scorePlayer < 3 && RPS.scoreCPU < 3)
          {
              RPS.userInput();
              RPS.CheckWhoWinsEach();
              RPS.CheckWhoWon();
          }
            RPS.playAgainn();
      }
  }
}

Answer 3

您是否尝试过放置RPS.playAgainn（）;恰好在前面的右括号之前？我在手机上阅读它，我认为它超出了RPS.playAgain = true区域，所以它会在完成后执行。

Answer 4

playAgainn（）函数的问题是它不是一个函数。我认为它不会编译。

public static bool playAgainn()
        {
            Console.WriteLine("Do you want to play again?(y/n)");
            string loop = Console.ReadLine();
            if (loop == "y")
            {
                Console.Clear();
                return true;
            }
            else 
            {
                return false;
            }
        }

在while循环结束后调用函数
