I’ve just added a slider with a 1 second delay to my template file.
https://run.pavlovia.org/Wake/brookes-template-2020/html
I used:
Each Frame
if slider.getRating() != None and sliderClick==0:
sliderClick=t
elif sliderClick == 0:
pass
elif t > sliderClick+1:
continueRoutine=False
The slider component is set not to force the end of the routine and I have sliderClick=0 in Begin Routine.
This also requires the code to be switched to Both after the initial translation so you can change null to undefined in the JavaScript.
