努力为我的C＃CONSOLE打字游戏实现计时器

Question

我目前的打字游戏功能（下面提供的代码）的目标是从10（硬），20（中）或30（简易）倒数，具体取决于游戏开始后用户的选择难度。 一旦倒计时达到零或用户的生命耗尽，游戏结束（停止倒计时）。 游戏正常启动，显示用户要输入的第一个单词，并从10开始倒数​​。我当前的问题是我无法弄清楚如何停止计时器倒数超过0。我尝试使用t .Change（Timeout.Infinite，Timeout.Infinite）并检查timeLeft == 0时不优先。 我真的觉得我想得太对（或想不到），在正确的方向上提供一些帮助或推动将不胜感激！

我的代码如下：

    class Program
{
    // List of words to be typed
    public static string[] words = { "some", "side", "add", "another", "would", "book" ,"water", "came" ,"your" ,"big","both", "from", "learn", "been", "me" ,"school" ,"land", "took", "place",
            "try", "line", "tell", "earth", "can", "do","children", "without", "my", "must", "take", "follow", "year", "is", "being", "different", "miss", "could", "on", "he", "open", "night", "were",
            "line","said", "around", "an", "plant", "know", "set","been", "life","young","of", "face", "we", "hand", "while", "is", "white", "call", "live","may", "study","after" ,"down", "him", "now", "different",
            "could", "over", "work","all", "mean","begin","go","fall", "really", "oil", "before","into","one","name","has","a", "well", "got","something","turn" };
    // Keeps track of words array
    public static int numWords = 88;
    public static int correctWords = 0;
    // Initialize our random number generator
    public static Random rand = new Random();
    // Handles user input
    public static string userInput = "";
    public static string endGameChoice = "";
    // Handles gamestate variables
    public static bool gameActive = false;
    public static int numLives = 0;
    public static int timeLeft;
    public static System.Threading.Timer t;


    // Entry Point
    static void Main(string[] args)
    {
        // Start the game
        Start();
    }

    // Handles gameplay
    static void Play()
    {
        // Assigns the current word to any random word in
        // the words array
        string currentWord = words[rand.Next(0, 88)];
        // Print the current word separated by lines
        Console.WriteLine("********");
        Console.WriteLine(currentWord);
        Console.WriteLine("********");
        // While the answser is incorrect/empty
        while (!userInput.Equals("exit"))
        {
            // Reads user input
            userInput = Console.ReadLine();
            if (userInput.Equals(""))
            {
                Play();
            }
            // Checks if userInput is equal to current word
            if (!(userInput.Equals(currentWord)))
            {
                // If incorrect, display loss of life
                Console.ForegroundColor = ConsoleColor.Red;
                Console.WriteLine("Incorrect!!!");
                Console.WriteLine("Lives: " + numLives);

Answer 1

尝试使用这个 。 协程应该可以解决您的问题，如果您可以使它正常工作。

Answer 2

您不需要编程计时器或线程即可拥有游戏计时器。 只需记录游戏开始时的时间即可：

//During initialization
var startTime = DateTime.Now;

而且，只要您希望显示或使用计时器，就可以对其进行计算：

var timerValue = DateTime.Now - startTime;
Console.WriteLine("Time elapsed: {0} seconds", timerValue.Seconds);

Answer 3

您可以通过这种方式使用Timer。

它为你工作

var timer2 = new Timer();
timer2.Elapsed += (o, e) =>
{
    Console.WriteLine("Time Elapsed {0}", e.SignalTime);
    timer2.Stop();
};
timer2.Interval = 1000;
timer2.Start();

Answer 4

作为对所出现问题的直接解决（计时器低于0），需要在不再需要计时器时停止计时器。 为此，请使用以下行：

t.Change(Timeout.Infinite, Timeout.Infinite);

您可以将此行添加到outOfLives和outOfTime方法的outOfTime ：

private static void outOfLives()
{
    t.Change(Timeout.Infinite, Timeout.Infinite);
    Console.WriteLine("Game over! You typed " + correctWords + " words correctly!");
    ...

和...

private static void outOfTime()
{
    t.Change(Timeout.Infinite, Timeout.Infinite);
    Console.WriteLine("Out of time! You typed " + correctWords + " words correctly!");
    ...

编辑：对不起。 只需重新阅读您的问题并意识到您已经尝试过此行。 您是否把它放在正确的地方？
