我正在尝试创建一个主机游戏，其中“ Martian”中的角色“ M”和“ SpaceCreature”中的角色“ 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，只要“ M”移动，“ S”也应该移动，但其自身也应该移动。 我需要以较低的速度移动“ S”以跟随“ M”。
截至目前，我已经使用箭头键上下移动了“ M”，并且“ S”也在同时移动。
我需要让'S'调慢点。我尝试过thread.Sleep，但这只会使“ S”消失并像小故障一样出现。我想我需要使用一个名为“ Console.keyAvailable”的东西，但是我很难确定该函数的放置位置。
//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();
}
}
}

您是否尝试将Thread.Sleep(100);放在s.Y = m.Y;之后，但是没有工作？
将睡眠时间更改为较短的时间可能会起作用。
也：
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)
}

您不需要其他线程...玩这个。按上/下箭头或退出以退出。您无需按住箭头键即可继续移动。您可能也对我的Console Snake示例感兴趣。

// wait for next keypress, or next movement

我如何通过点击上/下箭头键来进行'M'运动 做连续运动？
将“按下按键”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if (DateTime.Now >= m.nextMovement)块，以便仅检查下面的SpaceShip时间。现在，只有在您按住和/或按住箭头键时，“ M”才应该移动。
