c# - C# Text-Based Game 读取为没有错误但在第一次选择后关闭
问题描述
这是示例,请放轻松,因为这是我真正编写的第一个代码。我不确定格式是否会完全翻译。这段代码运行良好,直到最后一次编辑我将“rand”更改为“rand1”,就好像给了我一个“rand”已被使用的错误。现在,当我运行它时,我会“战斗或隐藏”,一旦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。

解决方案
当FightLoop方法开始执行时, playerChoice变量没有值。因此执行如下所示进入块 3 ,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();
}
由于您不在任何地方使用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“战斗”和“隐藏”的方法:
private static void FightLoop()
{
if (playerChoice == "fight")
{
fight();
}
else if (playerChoice == "hide")
{
hide();
}
else
{
Console.WriteLine("Choose (fight) or (hide).");
}
}
