[openvrml-develop] Re starting Animation Timers

[chickenmcboy <sit...@ho...>]

Hello everyone,
I've been working on a project using the ARToolkit example which uses
openVRML, however I seem unable to control when the animations start. 
Is there a way to reset the timers on call? Or perhaps is another method to
achieve the same goal?
I asked this question in the ARToolkit forum, and they suggested that I try
this mailing list instead. If anyone can help, I would be greatly
appreciative.
If I have posted twice, I apologize. I seemed to have needed to register
first.
Thanks!
Dom M.

You can start an animation by sending the current time to the associated
TimeSensor's set_startTime.  In OpenVRML, that would look something
like:

        openvrml::sftime_listener starttime_listener =
          n->event_listener<openvrml::sftime>("startTime");
        openvrml::sftime now(current_time);
        starttime_listener.process_event(now, now.value());
