[solved] show sketchpad for set time even if response is made and feedback arrives

  I have improved the code in this way and it seems to work:

  start_time = self.time()
  trial_duration = 10000
  lastRes1_time = 0
  lastRes2_time = 0
  lastRes3_time = 0
  lastRes4_time = 0
  import random
  schedule = random.randint(2000,3000)
  
  
  from openexp.mouse import mouse
  my_mouse = mouse(exp)
  my_mouse.set_visible()
  my_mouse.set_pos(pos=(660,260))
  my_mouse.set_buttonlist( [1] )
  my_mouse.flush()
  
  from openexp.canvas import canvas
  sketch = self.copy_sketchpad('choice')
  my_canvas = self.copy_sketchpad('choice')
  # Determine the absolute path:
  no = exp.get_file(u'/media/experiment/stim/no.jpg')
  uno = exp.get_file(u'/media/experiment/stim/O1.jpg')
  due = exp.get_file(u'/media/experiment/stim/O2.jpg')
  
  # Get ... as python variables
  trial = exp.get('choice_cond')
  
  
  while self.time() < start_time+trial_duration:
  
  
      # Wait for a mouse click
      button, position, timestamp = my_mouse.get_click()
      x, y = position
  
  
  ##############################
      if trial == (12):
          exp.set('correct', "RR")
              # button 1
          if x > (114) and x < (294) and y > (300) and y < (480):
                  exp.set('response', 1)
                  exp.set('response_____keyboard_response', "R1")
                  if  self.time() > lastRes1_time + schedule:
                      my_canvas.image(uno, center=True, x=None, y=670, scale=0.15)
                      lastRes1_time = timestamp
                      my_canvas.show()
                      self.sleep(600)
          # button 2
          if x > (432) and x < (612) and y > (300) and y < (480):
                  exp.set('response', 2)
                  exp.set('response_____keyboard_response', "R2")
                  if  self.time() > lastRes2_time + schedule:
                      my_canvas.image(due, center=True, x=None, y=670, scale=0.15)
                      lastRes2_time = timestamp
                      my_canvas.show()
                      self.sleep(600)
  
      sketch.image(no, center=True, x=None, y=650, scale=0.01)
      sketch.show()   
  

  is this the best solution?
  I hope it can be helpful for someone!

  Hi Sara,

  Depending on what you want to do, you seem to have come up with a very good solution. Keep in mind that with your script, the interaction continues to run after the first click. This means that participants can alter their choice after clicking.

  If you do not want to do so, the following example shows a single-click-and-wait procedure:

  # put the beginning of you script here, up until the while loop
  
  # get the starting time
  start_time = sketch.show()
  
  # wait until a buttonpress is made
  button = None
  passed_time = None
  while button == None and passed_time < trial_duration:
      # check for button presses
      button, pos, click_time = my_mouse.get_click(timeout=1)
      # check if button 1 was clicked
      if (114 < x < 294) and (300 < y < (480):
                  exp.set('response', 1)
                  exp.set('response_____keyboard_response', "R1")
      # check if button 2 was clicked
      elif (432 < x < 612) and (300 < y < (480):
                  exp.set('response', 2)
                  exp.set('response_____keyboard_response', "R2")
      # check if button 1 was clicked
      else:
                  # reset button
                  button = None
      # calculate the passed time
      passed_time = click_time - start_time
  
  # reset the screen
  sketch.clear()
  # show a blank screen
  end_time = sketch.show()
  passed_time = end_time - start_time
  
  # wait for a bit
  self.sleep(trial_duration - passed_time)

  Actually, I do want them to click several times (and, thus, make more than one choice) during a certain time interval while visualizing the same sketchpad) and subsequently go to the next trial. Thus, in this case, I don't need to reset the screen or to show a blank screen.
  I did not specified that, in this task, there are several buttons and in each trial two of them are available.

  Than you for the optimized script. By looking at it I have improved some things in mine!

  Excellent! I just included the script for the single button responses for future reference, it was by no means a comment on your design

  Good luck with testing!
