Description of the problem: My experiment is stuck on “initializing the experiment” and I am struggling to find the solution. It works fine locally. Thank you in advance.

Did you use a code component? If so, there is probably something wrong in one of them. Try looking for common mistakes (e.g. missing “;”, { and } missing or with the wrong indentation) and check these documents: PsychoPy Python to Javascript crib sheet for translation errors.

Your issues is:

SyntaxError: Identifier ‘pi’ has already been declared

Have you used pi as a variable?

I downloaded this from Pavlovia, so I am not really familiar with the code (I’m also not really familiar with code in general, so the help is highly appreciated). Here are some screenshots of the code that includes pi.

Thank you so much for the feedback.

That code comes from my 2020 crib sheet.

PsychoPy now automatically adds the following to all scripts.

const { abs, sin, cos, PI: pi, sqrt } = Math;
const { round } = util;

Therefore these should no longer appear in JSCode.

Thank you so much!! This solved the “Initializing the Experiment” issue!

I am now receiving this error:

Resources not downloading automatically all of a sudden (bug?)

URL of experiment: Pavlovia (previously working one), Pavlovia (previously working one), Pavlovia (one of the two new ones) Description of the problem: Many of my Pavlovia experiments are all of a sudden not loading the resources automatically. The page opens and the dialogue box never says “resources downloaded” or “downloading”, so then it says my resources don’t exist when I hit ‘okay’ to run the experiment.

Pavlovia: only download relevant stimuli for participant

Hello, I would like to assign different stimuli to different participants, and only download the relevant ones on the participant’s computer. But Pavlovia seems to always download the whole “resources” folder by default. Is there a way to avoid this and make it only download a subset of stimuli?

Online experiment "Unknown Resource" issue

In 2020.1 PsychoPy created an html folder for index.html and the javascript files. It also copied resources to html/resources and loaded everything in that folder into memory at the start of the experiment. If you needed a resource that was only mentioned in code you could just copy it to html/resources to tell PsychoPy to load it. This was inefficient because it meant that most experiments had two copies of its image, sound and video files which could nearly double the disk space used. From …

You could also change the experiment in PsychoPy to run as an earlier version. Try 2020.2.10.

Thank you so much, you’re incredibly helpful. All of my materials are in the html folder on github, the output in PsychoPy experimental settings is html, and it is still not finding my stimuli appropriately.

The html folder doesn’t work well with the latest version.

Hi, I moved this to a local folder, changed the output path to nothing, and reuploaded the task and it is still presenting the same issue.

Thank you in advance.
