Hello hope all is well! I have synced my PsychoPy experiment to Pavlovia, but when I try to pilot the experiment, I get stuck at initialising. I have figured out how to determine where the problem is, and have found the problematic line of code (illegal return error). It is not a builder coding erro…

I’ve made this today’s tip. Hopefully this post will help. [image] Wakefield's Daily Tips Blog Spreadsheets One of the aspects I love about PsychoPy is its use of spreadsheets. Before I switched to PsychoPy I used to user SuperLab 2. At the time, you had to en…

Perfect, I will try this. Thank you!

If you start with making a single loop which shows all of you stimuli in a random order then you can add an outer loop which selects sets of stimuli you want in the same block (assuming that is your intended design).

Okay, and what would happen to the builder code I have for each routine? That code is responsible for switching to the next animal after 10 clicks, for playing a sound when the animal is tapped, and for changing the image when the animal is tapped.

Okay, so I should be removing all builder code components and instead use loops to control all of this?

I don’t know what all of your code components do, but if you start with trying to get a single routine that will play all the stimuli from a single spreadsheet then an outer loop can be added to select rows 10 at a time

Okay, I will try this and get back to you. Thank you!

Hi again! I am having a bit of a hard time understanding exactly what to do. For the experiment, in routine 1 (titled animal1) when image_1L is clicked, sound_low1 needs to play for its duration of 4 seconds, and simultaneously popup_1L needs to appear over image_1L. popup_1L can disappear when the …

Hi again, I have tried making a simpler version of the experiment and uploading it to Pavlovia using no code. I am still getting the initialising error with the auto generated java script. Is there any way you can help me? Thanks!
