So is the conversion of python to JS not supported? I’m hoping I can just code this is JS and get it to run on Pavlovia for now. Much more comfortable with python at the moment and was enjoying PsychoPy and the builder GUI, but hopefully I’ll be able to figure out gratings in JS. Thanks for all the…
