PsyshoJS seems to flip angles

I’ve been toying around with setting up a grating experiment online and I’ve realised that PsychoJS seems to reflect angles about the vertical line, with respect to what one sees with the same experiment in psychopy. It does, of course, report the correct orientation.

For example

If I display a bar with an orientation of -20 degrees, in psychopy this bar is tilted slightly counter-clockwise of vertical. In psychoJS this bar is tilted slightly clockwise of vertical, but is still logged as -20 degrees.

This issue has been previously reported here

For now I can work around this, but it would be good to get a fix!



Hi Peter, thanks for flagging this! This bug will be fixed in the next release :slight_smile:

Okay great, thanks so much!

How can I have a look at the release schedule, so that I know when the patch is coming out? My temporary fix will actually become a flaw when this is patched so I need to be aware of that.



Hi Peter, not unless you upgrade, re-export for the latest version, and manually re-sync will your study be affected, so you are relatively safe in that respect. You can also check PsychoPy’s GitHub for new releases if you would rather not wait until the forum announcement, x
