  Hi all,

  So here is what I was able to achieve after posting the query-

  [pastebin:vPyqwLqT]

  Right now, I am able to create a canvas that shows the time lapsed in seconds and a form that consist of a task that I wish participants would do in allotted time. Although my script works in parts but does not achieve what I want. I want to display the time elapsed at the bottom of the form (not on a separate canvas as it is now), but right now it just shows the last value I get in the while loop present in the inline script.

  Any help will be much appreciated.

  Thanks!

  Hi Ahani,

  Looking at your script it seems like you want a continuously running countdown timer in your experiment, is that correct? I'm afraid that this is not possible, at least not without extensive inline scripting.

  What you can do, however, is present a static countdown timer that is updated with, for example, every new trial. Would that be sufficient? The script below shows how you can keep track of the time that is left as the variable timeleft (see code comments for details). You can then use this variable to display the time left in sketchpad items, etc. But it will be a static message, not a running counter.

  # Total duration in seconds
  total_time = 60
  # Time passed since the start of the experiment, as determined by the
  # presentation timestamp of an `instructions` item.
  time_passed = (self.time() - self.get('time_instructions'))/1000
  # Set the time that is left
  exp.set('timeleft', total_time-time_passed)
  

  Cheers!

  Thanks Sebastiaan,
  I was able to display the total time passed. I wanted a dynamic display to show the time passed.
