A simple timer example for the Grasshopper C# component

grasshopper-timer

Create a simple timer in Grasshopper using the built-in C# component with this example script.

What this does

Set runtimer to true. The component will build a list of the current time and date, once per second.

When runtimer is set to false, the timer is turned off and the list is displayed.

Code

  private void RunScript(bool runtimer, bool reset, ref object A)
  {
    if(runtimer) Example.TurnOnTimer();
    if(!runtimer) Example.TurnOffTimer();
    A = rtnlist;
  }

  // <Custom additional code> 

  public static List<string> rtnlist = new List<string>();

  public class Example
  {
    public static System.Timers.Timer aTimer = new System.Timers.Timer(1000);

    public static void TurnOnTimer()
    {
      rtnlist.Clear();
      aTimer.Elapsed += OnTimedEvent;
      aTimer.Enabled = true;
    }

    public static void TurnOffTimer()
    {
      aTimer.Elapsed -= OnTimedEvent;
      aTimer.Enabled = false;
    }

    private static void OnTimedEvent(Object source, System.Timers.ElapsedEventArgs e)
    {
      rtnlist.Add(e.SignalTime.ToString());
    }
  }
