我如何使用计时器/延迟使对象或角色在控制台窗口中移动？

Question

我正在尝试创建一个控制台游戏，其中“Martian”中的字符“M”和“SpaceCreature”中的字符“S”在 X 轴的两端保持相对，并在 Y 轴上上下移动。

我使用箭头键使“M”上下移动。但是“S”也应该移动，但只要“M”移动，它就会自己移动。我需要让“S”以较慢的速度移动以跟随“M”。

截至目前，我使用箭头键让“M”上下移动，“S”也在同时移动。

我需要让 'S'移动得更慢。我试过 thread.Sleep，但这只会让“S”消失并像故障一样重新出现。我想我需要使用一个名为“Console.keyAvailable”的东西，但我发现很难确定该功能的位置。

//X and Y get set constructors are defined in the abstract class:-SpaceObject 

public override void Draw()  //In both classes Martian and SpaceCreature

{

   Console.SetCursorPosition(X, Y);

   Console.WriteLine("S");  

   //In Martian class:- Console.WriteLine("M");

}

static void Main(string[] args)

{

   var m = new Martian(100, 10);

   var s = new SpaceShip(100, 10);

   const int MaxY = 25;

   m.Draw();  //Abstract override void method

   s.X = m.X + 100;

   s.Y = m.Y;

   s.Draw(); //Abstract override void method

   ConsoleKeyInfo keyInfo;

   while (true)

   {

      keyInfo = Console.ReadKey(true);

      Console.Clear();

      switch (keyInfo.Key)

      {

         case ConsoleKey.UpArrow:

         if (m.Y > 0)

         {

            m.Y--;

         }

         break;

         case ConsoleKey.DownArrow:

         if (m.Y < MaxY)

         {

            m.Y++;

         }

         break;

         }

         m.Draw();

         s.X = m.X + 100;

         s.Y = m.Y;

         s.Draw();

      }

   }

}

你不需要另一个线程......玩这个。按向上/向下箭头或退出退出；您不必按住箭头键继续移动。您可能还对我的Console Snake示例感兴趣。class Program{&nbsp; &nbsp; enum Directions&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; Up,&nbsp; &nbsp; &nbsp; &nbsp; Down,&nbsp;

你有没有试着把它放在Thread.Sleep(100);后面s.Y = m.Y;但没有用？将睡眠时间更改为更短的时间可能会奏效。还：while (true)&nbsp; &nbsp;{&nbsp; &nbsp; &nbsp; keyInfo = Console.ReadKey(true);&nbsp; &nbsp; &nbsp; Console.Clear();&nbsp; &nbsp; &nbsp; switch (keyInfo.Key)&nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;case ConsoleKey.UpArrow:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;if (m.Y > 0)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; m.Y--;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;case ConsoleKey.DownArrow:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;if (m.Y < MaxY)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; m.Y++;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;break;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;}&nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; m.Draw();&nbsp; &nbsp; &nbsp; s.X = m.X + 100;&nbsp; &nbsp; &nbsp; s.Y = m.Y;&nbsp; &nbsp; &nbsp; s.Draw(); //i think is better to put draw functions outside switch(key)&nbsp; &nbsp;}
