Hi Chris,
I would like to be able to change the background color/alpha during an experiment, presumably by manually changing color/alpha variables during an experiment.
If I were to go the route of using stimuli, e.g. blank fullscreen stimulus, I do want this to be on at all times across the multitask code, and therefore immune to any clear_stimulus_display() calls that exist. Would there be a way to do this?
If I do something like the following:
clear_stimulus_display()
live_queue_stimulus(blank_fullscreen)
update_stimulus_display()
Does both of the updates happen at once, i.e. there will be no frame in which blank fullscreen stimulus is not present?
Also, if you have a better suggestion that doesn’t require using a stimulus (e.g. somehow directly using stimulus_display background colors), please let me know. Thank you!
