display warning before sketchpad timeout
I would like to display stimuli till the key is pressed, so the duration of the sketchpat is set to '0'. However I do need to limit the waiting time, so I set the time out of the keyboard_response to 10s (btw, should it be 9995?)
The only problem I have is that a warning for the participant is needed, let's say after 6 seconds, that the system is waiting for the response.
How do I do that?
I tried coroutine, however either i am not using it correctly , or it's not suitable for the purpose.
After struggling for a while, maybe here in the forum someone could help.
