Code component doesn't work

Builder
1

OS: Win11 Pro
PsychoPy version: 2021.2.3
Standard Standalone? : yes
What are you trying to achieve?: go/no-go experiment

What did you try to make it work?: I show a fractal, then a target image (containing left/right targets), and based on these information, participant presses a key. Based on these three (fractal, target and key press), I should show a feedback image. The feedback is probabilistic and has many different conditions, so I have coded it.
I have defined a function that should create a window and based on the if loops, show the correct image using the visual.ImageStim function, for 1 second.

What specifically went wrong when you tried that?: It doesn’t show the feedback images. It It seems like it doesn’t even notice the code component.

Move the code component to the top of the routine

Thanks @wakecarter, did so, but still doesn’t work.

Here’s my script, I don’t think there’s an error in it, because I ran it in the coder and it works. Maybe it’s because I define a window and want to access the screen on top of the ongoing use of screen in the experiment?

rp = 0.8 # reward probability

Your code is in Begin Routine, which is before any key will be pressed. If you want to keep checking for a response then it needs to be in Each Frame.

If a key press ends the routine, then you could put the code in End Routine and then have the feedback in the following routine (or your pop-up might work in End Routine).

thanks a lot @wakecarter, problem solved with your instructions :slight_smile:
