如何在C＃中每隔幾秒調用一次特定的方法？

Question

「機器人遊戲」是我開發的第一款基礎遊戲。洋紅色的'＃'字符是敵人，它應該在這張地圖上有一個隨機的移動，但是它的隨機移動速度太快了，我嘗試使用線程，但是它影響了所有角色的速度。現在，我需要每隔100毫秒調用一次「Enemy」方法。

您可以使用System.Timer。但是，應該預先警告，這些定時器可能不如您想要的那麼準確。你永遠不會在Windows等非實時操作系統上獲得完全準確的定時器，但如果你想要更好的定時器準確性，Multimedia timer可能會有所幫助。

從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); 
    } 
}
