C# 基于文本的游戏读取没有错误，但在第一次选择后关闭

Question

这是示例，请放轻松，因为这是我真正编写过的第一个代码。我不确定格式是否会完全翻译。在我将 "rand" 更改为 "rand1" 的最后一次编辑之前，此代码运行一直很好，就好像给我一个 "rand" 已被使用的错误。现在，当我运行它时，我到达 "fight or hide" 并且只要我输入其中一个选项，终端就会关闭。然而，Visual Studio 没有显示任何错误。

Answer 1

问题出在您的 Welcome() 方法上。您要求玩家选择战斗或隐藏，但您没有将答案保存在 playerChoice 变量中。因此，当您在 FightLoop 上检查 playerChoice 时，它会在其他运行行 Console.WriteLine("Choose (fight) or (hide)."); 处结束。但是因为您没有等待任何按键，所以程序完成并关闭。要修复，您必须：

阅读你的 Welcome 方法中的玩家选择，将行 Console.ReadLine(); 更改为 playerChoice = Console.ReadLine();

等待战斗循环 else 部分的任何按键，在 Console.WriteLine("Choose (fight) or (hide).");

之后添加 Console.ReadLine();

Answer 2

当 FightLoop 方法开始执行时 playerChoice 变量没有值。所以执行转到 block 3 如下所示，然后退出方法。

private static void FightLoop()
{
    if (playerChoice == "fight")
    {
         //block 1
    }
    else if (playerChoice == "hide")
    {
         //block 2
    }
    else
    {
        //block 3
        Console.WriteLine("Choose (fight) or (hide).");
    }
}

您需要更改 Welcome 方法的最后一行，以便将读取的字符串保存到 playerChoice 变量中。

private static void Welcome()
{
    Console.WriteLine("Hello Traveller, What is your name?");
    playerName = Console.ReadLine();

    Console.WriteLine("Well Hello, " + playerName);
    Console.WriteLine("You are alone in a dark dungeon. You can see a room behind you and a long hall in front of you.");
    Console.ForegroundColor = ConsoleColor.DarkRed;
    Console.WriteLine("You hear an enemy nearby...");
    Console.ForegroundColor = ConsoleColor.DarkCyan;
    Console.WriteLine("(fight) or (hide)?");
    Console.ForegroundColor = ConsoleColor.Gray;
    playerChoice = Console.ReadLine();
}

由于您没有在任何地方使用 rand1 变量，您可以删除以下行。

Random rand1 = new Random();

此外，一个好的做法是使用 "fight" 和 "hide" 的方法：

private static void FightLoop()
{
    if (playerChoice == "fight")
    {
         fight();
    }
    else if (playerChoice == "hide")
    {
         hide();
    }
    else
    {
        Console.WriteLine("Choose (fight) or (hide).");
    }
}
