Change default Escape function to stop/end the experiment immediately

  Hi @Carlosvandango ,

  
  

  Escape should not immediately stop the experiment. Instead, it will ask for confirmation by a 'q' press, right? I guess it will be tricky/ near impossible to change the function of the Esc button...

  
  

  Am I right, @sebastiaan ?

  
  

  Cheers,

  Hi @lvanderlinden

  Yes the escape key does currently pause the experiment and asks for a 'q' key press to confirm, but that is not what I want.

  I would like by pressing the escape key the experiment quits/stops immediately.

  I saw in another post, that it is possible to make changes to the exp.pause () function such as:

  def my_custom_pause_function():
      print('I don\'t do anything right now, but I could!')
  
  exp.pause = my_custom_pause_function

  Hi @Carlosvandango ,

  If you add some code to my_custom_pause_function() that causes a crash, then OpenSesame will stop when you press Escape. This can be anything, but the most elegant solution is to raise an informative Exception , like so:

  def my_custom_pause_function():
      raise Exception('The escape key was pressed!')
  
  exp.pause = my_custom_pause_function
