I’m trying to set up a task in Builder, and would like the start and end times of the stimuli (relative to the start of the task) in my CSV log; I want to make sure my timing is what I expect it to be.
I feel like there’s probably an easy way to do this, but I’m not seeing it anywhere. It looks like I could bodge something together with code blocks but… there must be an easier way?
For what it’s worth, my code blocks tactic is:
thisExp.addData('stim_onset', stim.tStart)
but that’s reporting times relative to the start of the routine and I don’t know how to get an end time out of it.
Also: I could probably hack this up in Coder pretty easily but I’m really, really hoping to have a thing that runs easily both in locally-installed psychopy and on pavlovia.
Add a Variable (call it routineStart or something), set its “Routine start value” to core.monotonicClock.getTime(). globalClock would probably work as well; I’m not sure why there are multiple global clocks. I think core.monotonicClock is probably the best global clock to use.
Add a Code block, running at End Routine, that does thisExp.addData('stim_onset', routineStart + stim.tStart)
I don’t think there’s a way to log the end/offset times for stimuli.
This seems like something to add to the Components, but I’m not sure if this is the kind of PR that would get accepted…
