ignor my question
times is a different issue

In general it is needed for any variable this first appears in a loop or conditional clause (i.e. indented) on the Python side. I tend to use =0 for numbers, =’ ’ for text and =[] for lists if I don’t have a default value in mind but this probably doesn’t matter.

is it possible that variable component(in this case times variable) doesn’t translate to JS well?

Correct. The variable component was created as a simpler version of a code component. However, it doesn’t have auto translate.

You need Begin Experiment times=[0,0,0] and Each Frame times=[t/60**2,t/60,t]
