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
{
enum Directions
{
Up,
Down,
None
}
static void Main(string[] args)
{
DateTime next;
bool quit = false;
ConsoleKeyInfo cki;
Directions direction = Directions.None;
Console.Clear();
Console.CursorVisible = false;
var m = new Martian();
var s = new SpaceShip();
m.Draw(true);
s.Draw(true);
do
{
// wait for next keypress, or next movement
next = new DateTime(Math.Min(m.nextMovement.Ticks, s.nextMovement.Ticks));
while(!Console.KeyAvailable && DateTime.Now < next)
{
System.Threading.Thread.Sleep(10);
}
// was a key pressed?
if (Console.KeyAvailable)
{
cki = Console.ReadKey(true);
switch (cki.Key)
{
case ConsoleKey.UpArrow:
direction = Directions.Up;
break;
case ConsoleKey.DownArrow:
direction = Directions.Down;
break;
case ConsoleKey.Escape:
quit = true;
break;
}
}
// does anything need to move?
if (DateTime.Now >= m.nextMovement)
{
switch(direction)
{
case Directions.Up:
m.MoveUp();
break;
case Directions.Down:
m.MoveDown();
break;
case Directions.None:
m.UpdateNextMovement();
break;
}
}
if (DateTime.Now >= s.nextMovement)
{
s.MoveToward(m);
}
} while (!quit);
}
}
public abstract class SpaceObject
{
public int X;
public int Y;
public int MovementDelay;
public DateTime nextMovement;
abstract public void Draw(bool Visible);
public void MoveUp()
{
if (this.Y > 0)
{
this.Draw(false);
this.Y--;
this.Draw(true);
}
this.UpdateNextMovement();
}
public void MoveDown()
{
if (this.Y < Console.WindowHeight - 1)
{
this.Draw(false);
this.Y++;
this.Draw(true);
}
this.UpdateNextMovement();
}
public void MoveToward(SpaceObject so)
{
if (so.Y < this.Y)
{
this.MoveUp();
}
else if (so.Y > this.Y)
{
this.MoveDown();
}
else
{
this.UpdateNextMovement();
}
}
public void UpdateNextMovement()
{
this.nextMovement = DateTime.Now.AddMilliseconds(this.MovementDelay);
}
}
public class Martian : SpaceObject
{
public Martian()
{
this.X = 1;
this.Y = Console.WindowHeight / 2;
this.MovementDelay = 100;
this.nextMovement = DateTime.Now.AddMilliseconds(this.MovementDelay);
}
public override void Draw(bool Visible)
{
Console.SetCursorPosition(this.X, this.Y);
Console.Write(Visible ? "M" : " ");
}
}
public class SpaceShip : SpaceObject
{
public SpaceShip()
{
this.X = Console.WindowWidth - 2;
this.Y = Console.WindowHeight / 2;
this.MovementDelay = 750;
this.nextMovement = DateTime.Now.AddMilliseconds(this.MovementDelay);
}
public override void Draw(bool Visible)
{
Console.SetCursorPosition(this.X, this.Y);
Console.Write(Visible ? "S" : " ");
}
}

如何通过点击向上/向下箭头键而不是连续移动来进行“M”移动？
将“按下一个键”块更改为：
// was a key pressed?
if (Console.KeyAvailable)
{
cki = Console.ReadKey(true);
switch (cki.Key)
{
case ConsoleKey.UpArrow:
m.MoveUp();
break;
case ConsoleKey.DownArrow:
m.MoveDown();
break;
case ConsoleKey.Escape:
quit = true;
break;
}
}
然后删除该if (DateTime.Now >= m.nextMovement)块，这样您就只剩下检查下面的 SpaceShip 时间了。现在你的“M”应该只在你点击和/或按住箭头键时移动。

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)
{
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(); //i think is better to put draw functions outside switch(key)
}
