URL of experiment: Pavlovia psychopy version: 2020.2.10 Description of the problem: I have an experiment that has 3 different modes of operation depending on participant data. 2 methods just click on one of 2 boxes. The other drags a button into one of 2 boxes. Everything works fine offline and …

Thanks Sotirios. I really appreciate your help. Phil

Hi @philBartlett , no problem, alright I tried piloting the study on several iPads and can see there are issues with linking to a really old version of PsychoJS (3.2), which OK should be fairly straighforward to address, but was unable to get to the drag and drop routine. Can I ask which iPad model a…

Sotirios, The latest version of my experiments no longer runs on either of the 2 ipads that I own. The only changes I have made to experiments is to add .wav files. The ipads I have are: ipad 8th generation - MYL92VC/A - ios 14.4 ipad 4th generation - MD510C/A - ios 10.3.3 The following posting…

Thanks Sotiri. It does seem to run but there is no sound. Also it takes a while before it allows me to move a object. Your comment about using mp3 files. I thought you couldn’t use them in psychopy because of licensing issues. I have 4 experiments which all exhibit the same problem how do I apply …

Thanks Wakefield for you reply. I got a response from Sotiri in which he got it to work but you suggestion is a good idea and I will look into implementing it. Phil

My experiment developed offline on psychopy references sound .wav files. How do I make the online version use .mp3 files easily?

.wav files can work online as well. It’s .ogg files that don’t. However, what I do is have the filename minus the extension in the Excel file (or whatever) and then use a both component to add the appropriate extension. Alternatively, if you set a flag early in the experiment (in a Both component,…
