如何在C＃中每隔几秒调用一次特定的方法？

Question

“机器人游戏”是我开发的第一款基础游戏。洋红色的'＃'字符是敌人，它应该在这张地图上有一个随机的移动，但是它的随机移动速度太快了，我尝试使用线程，但是它影响了所有角色的速度。现在，我需要每隔100毫秒调用一次“Enemy”方法。

您可以使用System.Timer。但是，应该预先警告，这些定时器可能不如您想要的那么准确。你永远不会在Windows等非实时操作系统上获得完全准确的定时器，但如果你想要更好的定时器准确性，Multimedia timer可能会有所帮助。

从MSDN

System.Timer例如：

public class Timer1 
{ 
    private static System.Timers.Timer aTimer; 

    public static void Main() 
    { 
     // Normally, the timer is declared at the class level, 
     // so that it stays in scope as long as it is needed. 
     // If the timer is declared in a long-running method, 
     // KeepAlive must be used to prevent the JIT compiler 
     // from allowing aggressive garbage collection to occur 
     // before the method ends. You can experiment with this 
     // by commenting out the class-level declaration and 
     // uncommenting the declaration below; then uncomment 
     // the GC.KeepAlive(aTimer) at the end of the method. 
     //System.Timers.Timer aTimer; 

     // Create a timer with a ten second interval. 
     aTimer = new System.Timers.Timer(10000); 

     // Hook up the Elapsed event for the timer. 
     aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent); 

     // Set the Interval to 2 seconds (2000 milliseconds). 
     aTimer.Interval = 2000; 
     aTimer.Enabled = true; 

     Console.WriteLine("Press the Enter key to exit the program."); 
     Console.ReadLine(); 

     // If the timer is declared in a long-running method, use 
     // KeepAlive to prevent garbage collection from occurring 
     // before the method ends. 
     //GC.KeepAlive(aTimer); 
    } 

    // Specify what you want to happen when the Elapsed event is 
    // raised. 
    private static void OnTimedEvent(object source, ElapsedEventArgs e) 
    { 
     Console.WriteLine("The Elapsed event was raised at {0}", e.SignalTime); 
    } 
}
