Gamepad/pyglet/pygame

Hi there!

I’m new on PsychoPy and on Python. I have built an experiment using the builder view. I would like to use a joystick for collecting responses. I have heard about gamepad-related issues. Did someone find a solution?

As far as I know this is still the state of the art.

Joystick/refresh rate catch-22

OK, I have a theory about what the issue is and a horrible kludge solution that works, barely. There is a pyglet joystick.py demo available in the bitbucket repository, code copied at the bottom of this post. You can run this from the psychopy python install and it works just fine, so we know pyglet can talk to a joystick in principle. However, the way this demo seems to work is that it’s not worrying about event dispatchers at all, it’s just checking the joystick’s status every time the windo…

Thank you for your reply!

I would to try it and see what happens. I built my experiment in the builder. Can I insert these scripts in a code component or do I have to insert them in the coder?

You’ll definitely have to do it in the coder, in fact I’m not sure you can make it compatible with a builder-based study at all because it requires re-initializing the joystick on every frame.

What do you mean with re-initializing the joystick on every frame?
