[solved] Custom Feedback

  Hi Elvio,

  It seems that you're doing things correctly. If you have Python variable x, which lives in your inline_script items, you need to use exp.set('x', x) to create an experimental variable that has the same name and value. Once you've done that you can refer to this variable throughout OpenSesame, using the square-bracket notation ([x]). See also:

  • http://osdoc.cogsci.nl/2.9/usage/variables-and-conditional-statements/#getting-and-setting-variables-in-inline_script-items

  One thing that comes to mind is that you may be exp.setting the variable too late. For example, if you set the variable during the run phase, it won't be available in sketchpads, because these are prepared in advance, during the prepare phase. For more information, see:

  • http://osdoc.cogsci.nl/usage/prepare-run/

  Also, it won't hurt to print a little information to the debug window, to make sure that x really has the correct value. Like so:

  print('X = %s' % x)
  exp.set('x', x)
  

  Cheers!

  I see... Thanks for your hint, I will try with a feedback object instead of a sketchpad one.

  It works!

  Indeed, now that i look at the script I see that sketchpads, also the ones outside a sequence, are prepared in advance; at the beginning the value of X was 0, so it all makes sense.

  The feedback object works fine and reads the last value of X.

  Thanks a lot!
