How to call a particular method every some seconds in c#?
提问by Hossam Hassan
"Robot Game" is the first basic game I developed. The Magenta '#' character is an enemy and it is supposed have a random movement in this map, but its random movement is too fast and I tried to use Threading but it effects all characters' speed. Now, I need To call the "Enemy" method every 100 milliseconds.
“机器人游戏”是我开发的第一个基础游戏。Magenta '#' 角色是一个敌人，它应该在这张地图中随机移动，但它的随机移动太快了，我尝试使用线程，但它影响了所有角色的速度。现在，我需要每 100 毫秒调用一次“敌人”方法。

You can use System.Timer. However, be forewarned that these timers might not be as accurate as you may desire. You'll never easily get a fully-accurate timer on a non-realtime OS such as Windows, but if you want better timer accuracy, a Multimedia timermight help.
您可以使用System.Timer。但是，请注意，这些计时器可能不像您希望的那样准确。在 Windows 等非实时操作系统上，您永远不会轻易获得完全准确的计时器，但如果您想要更好的计时器精度，多媒体计时器可能会有所帮助。
System.Timer example from MSDN:
来自 MSDN 的 System.Timer 示例：
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);
}
}
