Question

出于兴趣，我正在C＃控制台中创建一个过程生成的平台程序。但是，我发现该程序的运行速度比我预期的要慢，除非按住任意按钮，然后程序会返回到作为timeLapse输入的预期数量。

当前唯一具有功能的按钮是空格键，可让您跳转。我也没有在//此代码行上进行代码测试，并且消除了问题。有人对此有解释或文章吗？我自己找不到很多东西。

可以添加PlatformGenerator代码，尽管我认为这不是必需的。

程序代码：

namespace TestProject.Procedural_Generation
{
    public class PlatformManager
    {
        #region Variables
        // Game settings
        private static char[,] screen;
        private static int screenWidth = 96;
        private static int screenHeight = 20;

        // Platform generation settings
        private static int minGeneration = 4;
        private static int maxGeneration = 18;

        private static PlatformGenerator pg;
        private static List<Platform> platforms = new List<Platform>();

        // Physics variables
        private static int oldX = 0;
        private static int currentX = 0;
        private static int currentY = 8;
        private static string toSkip = "";

        private static Player player;

        // Timer variables
        private static float timeLapse = 100;
        private static float jumpTime = 200;
        private static Timer graphicUpdater;
        private static Timer physicUpdater;
        private static Timer jumpTimer;
        private static bool isJumping = false;

        private static long score = 0;
        #endregion

        public PlatformManager()
        {
            screen = new char[screenHeight, screenWidth];
            pg = new PlatformGenerator(minGeneration, maxGeneration);
            player = new Player();

            // Physics
            physicUpdater = new Timer(timeLapse);
            physicUpdater.Elapsed += ExecutePhysics;
            physicUpdater.AutoReset = true;
            physicUpdater.Enabled = true;

            jumpTimer = new Timer(jumpTime);

Answer 1

不确定我是否理解正确，但是

Console.ReadKey（true）.Key == ConsoleKey.Spacebar

等待按键发生，因此只有在实际按下按键后，代码才会被处理，如果您删除该程序，因为它不会等待按键发生，因此显然会“更快”地移动

按下按钮时，C＃控制台程序运行得更快
