问候！
我是C＃的新手，我一直在关注YouTube的教程播放列表来创建相关应用程序。然而，现在我只是完成系列赛的一段视频，我决定尝试给我的游戏一点点我自己的扭曲。游戏非常基本，有一个 playerUnit （主要玩家），一个 enemyUnit （敌人）和 allyUnit （第二个玩家） 。我在教程系列的开头简单地创建了 allyUnit ，甚至没有想过将它变成第二个玩家。然而，凭借从其他剧集中获得的知识，我决定将其变成第二个玩家。在它自己的脚本中，我只使用相同的代码进行运动，我用于 playerUnit ，只更改运动键。但是，当按下键并且立即移动时， playerUnit 响应正确，而第二个玩家则滞后。它需要一段时间才能开始移动，有时会以不同的间隔移动。
在 Game.cs 脚本中，在第43和44行中，在 public void Run（）中，我注意到如果我使用 allyUnit.Update 切换 playerUnit.Update ， allyUnit 将不再滞后，但 playerUnit 将会延迟。因此，代码中首先出现的不会滞后，另一个会出现。这让我觉得它可能与Update有些冲突？既然它同时更新键输入，在同一个循环中还是什么？鉴于我还在学习，我可能会说最大的亵渎，但这也是我创建这个主题的原因。
以下是相关脚本：
Game.cs
using System;
using System.Threading;
using System.Diagnostics;
namespace DodgeGame

public class Game
{
public Game () //This function runs when the player starts a New Game, thus creating the characters
{
//Creates a player unit and sets its position/graphic
playerUnit = new PlayerUnit(30, 10, "@");
//Creates an enemy unit and sets its position/graphic
enemyUnit = new EnemyUnit(Console.WindowWidth - 1, 10, "X");
//Creates an ally unit and sets its position/graphic
allyUnit = new AllyUnit(12, 5, "O");
stopwatch = new Stopwatch();
}
private Stopwatch stopwatch;
private Unit playerUnit;
private Unit enemyUnit;
private Unit allyUnit;
public void Run() //This function is called once the New Game has begun, thus drawing the characters
{
stopwatch.Start ();

while (true)
{
//Time since last frame
int deltaTimeMS = (int)(stopwatch.ElapsedMilliseconds - timeAtPreviousFrame); //1000 / desiredFPS;
timeAtPreviousFrame = (int)stopwatch.ElapsedMilliseconds;
//Update units
playerUnit.Update (deltaTimeMS);
allyUnit.Update (deltaTimeMS);
enemyUnit.Update (deltaTimeMS);
//Detect collide (True = Game Over)
if (playerUnit.IsCollidingWith (enemyUnit) || allyUnit.IsCollidingWith(enemyUnit))
{
GameOver ();
}
//Draws all units
playerUnit.Draw ();
allyUnit.Draw ();
enemyUnit.Draw ();
//Tiny sleep to avoid running at too high FPS
Thread.Sleep (5);

我尝试专门为 allyUnit 创建一个不同的单独的 Update（）函数，但它不起作用。我还尝试了其他一些小事，但没有人做过这件事。我该怎么做才能解决这个问题？

答案 0 :(得分：-1)
我怀疑您的PlayerUnit和AllyUnit Update（）方法都调用了ReadKey（）。当首先调用任何Update（）方法时，将抓住按下的键，不再为第二个方法调用留下按键事件。
无论如何，将任何类型的I / O直接包含在逻辑类中都是不好的形式，所以我要做的是在Game.cs中创建一个单独的Update函数来读取密钥，然后将密钥读取传递给PlayerUnit。 Update（）和AllyUnit.Update（）调用。
编辑： 在Game.cs中有类似的东西：
Update(mSecs) {
ConsoleKeyInfo cki = Console.ReadKey();
playerUnit.Update(cki, mSecs);
allyUnit.Update(cki, mSecs);
enemyUnit.Update(mSecs);
}
然后相应地更改* Unit类中的方法。 您还必须更改Run（）方法，以通过调用此方法来替换Update调用。
