Eyetracker Record -- Experiment freezes at the eyetracker stop record component

[nic]

OS (e.g. Win10): macOS 12.5
PsychoPy version (e.g. 1.84.x): 2023.1.2

Hi!

I’m building an eyetracker experiment (testing with Mouse Gaze), where I use two eyetracker record components in PsychoPy Builder (one to start the recording and one to stop recording).

When I run my experiment, the experiment freezes on a grey screen at the eyetracker stop record component. I have to hit ESC to force-quit the experiment and there is no error message recorded either. If I remove the eye tracker stop record component, the experiment runs to completion smoothly.

I’m new to Psychopy so I’m quite lost on how to approach this issue and would appreciate any advice. Thank you!

What are you trying to achieve?:
I would like to prevent the experiment from hanging at the eyetracker stop record component.

I ran into the same issue with PsychoPy version 2024.1.4 on macOS 14.4.1. I’m pretty sure that this is a bug in the code and I have just submitted a PR to fix it.

For a quick and easy solution however, see Sol’s reply to an earlier topic:

@sol

Instead you will need to add custom code to the project where you want to start or stop recording by adding custom code components. To start recording add a new routine and then add the following to the begin routine tab of a custom code component in the routine:

eyetracker.setRecordingState(True)

To stop recording add a new routine and then add the following to the end routine tab of a custom code component:

eyetracker.setRecordingState(False)

Starting and stopping of recording should be done when no keyboard events are expected so if one occurs during that 0.5 second time period it is not dropped.

A proper fix for this will be available in the a future release. Sorry for any inconvience.
