Consistent image size across screens

It works! Thank you so much!

Hi, I am trying to run screen_scale.ppy on my computer with PsychoPy 2021.1.4, it runs offline just fine, but when I try to run PsychoJS in local debug mode via Runner I get either folder directory or “initialising the experiment” screen forever. I understand that the problem is in the newer version of the Psychopy that I am using. Could you, please, be so kind and hint what should be updated in order to make it work? We wanted to add your code (and of course a proper citation in a paper to be) to our online experiment.
We will greatly appreciate your help,
Dina.

Hi Dina,

First, please can I check that you are using the psyexp Builder file, not the py file.

If you are using the latest version then you probably don’t need the following code in code_JS

event=psychoJS.eventManager;
thisExp=psychoJS.experiment;
win=psychoJS.window;

Please could you check the Browser console for the exact error if disabling code_JS doesn’t work

Thank you for the prompt reply.

I am using screen scale.ppyexp via builder view (window–> runner–>Run PsychoJS).

This is what I got after removing the lines:

This what I get with the lines you mentioned:

Are you trying to test the online code locally? I’ve never managed to get this to work so I do all my testing remotely

Got it! Sorry for bothering you.
Anyway removing the lines helped at the stage of merging your code with our code.
Many thanks,
Dina.
