Display mirrored, upside-down text?

  Hi Florian,

  That's a tricky one! And you already had the solution; you have to use images of text rather than the text function. Of course the same goes for the instructions; you have to use an image displaying the instruction text.

  Cheers,

  And one more thing: if by feedback you meant giving participants their accuracy scores, then you probably already anticipated that this would be especially tricky. The only thing I can think of is that you'd have 100 tiny images ready in the filepool, that all contain a mirrored number between 0 and 100. You would then create the canvas/sketchpad by placing one of these over an image that already contains a mirrored "Your accuracy is %"

  Cheers,

  Well, since it seems that you'll have to do quite a lot to make this work. You could also check out this link: http://ubuntuforums.org/showthread.php?t=2078323. They succeeded in displaying upside down text, by mapping proper letters to other unicode characters that look like the original letters would look after the flip. It's quite funny, but I'm not sure whether it really solves your issue.

  Hi.

  thanks for the link Eduard. That thread took me to this website. It produces the following string for my instructions:

  ǝɹɐnbs ʇɹɐʇs ǝɥʇ ɥɔnoʇ

  That might actually work! Unfortunately, OpenSesame displays this as:

  

  I used this command to try and display it:

  my_canvas.text('ǝɹɐnbs ʇɹɐʇs ǝɥʇ ɥɔnoʇ')
  

  This would have been a better solution than making image files every time I want to change something...

  ... but I guess that's what I'll have to do then.

  @Josh: I was planning to display a time as feedback: "You took X seconds". But it's not that important.

  Hi Florian,

  I was just playing around with the font type, which OpenSesame uses and just when I was about to give up, I found one that does display ʇxǝʇ ǝpısdn. If you go to the experiment settings you can choose Gentium and should be able to see the text. Probably there are also other fonts that you could use, you just have to find them.
