Question

我正在编写一个简单的基于控制台的游戏。在游戏中，我有两个功能应该移动两件事 - 一个球拍和一个球。但是当我使用两个具有Thread.sleep的循环时，游戏不起作用。如何使用Thread.sleep的两个循环并使其正常运行？

我的代码：

class Program
{
    static void Ball()
    {

    }

    static void Main(string[] args)
    {
        int x = 10; int y = 10;
        int dx = 1; int dy = 1;
        ConsoleKeyInfo Exit = new ConsoleKeyInfo();
        do
        {
            Console.SetCursorPosition(x, y);
            Console.WriteLine(" ");
            x += dx;
            y += dy;
            Console.SetCursorPosition(x, y);
            Console.Write("*");
            Thread.sleep(95);
            if (x > 77) dx = -dx;
            if (x < 2) dx = -dx;
            if (y > 22) dy = -dy;
            if (y < 2) dy = -dy;
        } while (true);

        int a = 2;
        int b = 23;
        int da = 1;

        Console.SetCursorPosition(a, b);
        Console.Write("          ");
        if (Console.KeyAvailable)
        {
            ConsoleKeyInfo k = Console.ReadKey(true);
            if (k.Key == ConsoleKey.LeftArrow) a = a - da;
            else if (k.Key == ConsoleKey.RightArrow) a = a + da;
            if (a > 78) a = -da;
            if (a < 2) a = -da;
            Thread.Sleep(200);
        }
        Console.SetCursorPosition(a, b);
        Console.Write("~~~~~~~~~~");
    }
}

当我运行您提供的示例代码时，应用程序将运行。也就是说，球（*）将在屏幕周围移动。您是否期望球在屏幕上移动，并且在按下箭头时要划动并移动球拍？如果是这样，你应该看看你是如何循环的。我看到的问题是你有一个绘制球的循环，你的循环永远不会结束，因此你的代码不会绘制球拍和/或反映你的箭头键变化。您是否期望Thread.Sleep暂停循环并允许您绘制/移动球拍？

更新：

namespace ConsoleGame

class Ball {

    private static Ball _instance;

    private int _a = 10, _b = 10;
    private int _dx = 1, _dy = 1;

    private int _timer = 0;
    private int _milliseconds = 1000;

    private Ball() { }

    public static Ball Instance {
        get {
            if(_instance == null) {
                    _instance = new Ball();
            }

    public void Move(int speed) {

        if (_timer >= _milliseconds) {
            // Set the cursor position to the current location of the ball
            Console.SetCursorPosition(_a, _b);
            // Clear the ball from the screen
            Console.WriteLine(" ");
            _a += _dx;
            _b += _dy;
            // Set a new locatio for the ball
            Console.SetCursorPosition(_a, _b);
            // Draw the new ball location on screen
            Console.Write("*");
            if (_a > 77) _dx = -_dx;
            if (_a < 2) _dx = -_dx;
