[英]C# Console program runs faster when button is pressed
我出於興趣,正在C#控制台中創建一個過程生成的平台程序。 但是,我發現該程序的運行速度比我預期的要慢,除非按住任何按鈕,然后程序都會返回到作為timeLapse輸入的預期數量。
當前唯一具有功能的按鈕是空格鍵,它使您跳轉。 我也沒有在//此代碼行上進行代碼測試,並且消除了問題。 有人對此有解釋或文章嗎? 我自己找不到很多東西。
可以添加PlatformGenerator代碼,盡管我認為這不是必需的。
程序代碼:
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();

physicUpdater = new Timer(timeLapse);
physicUpdater.Elapsed += ExecutePhysics;
physicUpdater.AutoReset = true;
physicUpdater.Enabled = true;
jumpTimer = new Timer(jumpTime);
jumpTimer.Elapsed += Land;
jumpTimer.Enabled = true;
// Graphics
graphicUpdater = new Timer(timeLapse);
graphicUpdater.Elapsed += ExecuteGraphics;
graphicUpdater.AutoReset = true;
graphicUpdater.Enabled = true;
while (true)
{
score++;
}
}
private void Land(object source, EventArgs e)
{
isJumping = false;
}

}
else if (screen[y, x] == '=')
{

}
不知道我是否理解正確,但是
Console.ReadKey(true).Key == ConsoleKey.Spacebar
等待按鍵發生,因此直到實際按下按鍵后,代碼才會被處理;如果您刪除該程序,顯然它將“更快”地移動,因為它不會等待按鍵發生
