Re: [psychopy-users] Cannot stop script

[Jonathan Peirce]

Why would you expect "Cmnd+." to have any effect? The scripts stop only
if you program it to stop on a particular key press. For instance, quite
a few of the Coder demos are programmed to quit if the Esc key or the Q
key are pressed. The builder experiments, by default, will quit at any
time if Esc is pressed. Any other keyboard handling you need to program
in yourself. If you don't give any instructions about how/when to end
then scripts won't end. While preparing a new experiment it's a good
idea to use a window for the experiment rather than full-screen mode -
that way you can always press the big red stop button to force an end if
you forgot to program one in.

Cmd+. is listed as the option to "stopScript" in the key-bindings preferences. However, this will only work if the Coder or Builder application window has the focus, which is rarely the case when an experiment is running. So perhaps this keybinding is misleading?

Phoebe, you might check your Experiment settings (blue square icon with double headed white arrow inside) and make sure "Enable escape" is selected (enabled = checked). This only influences that particular builder experiment.

And on mac you can force-quit a program rather than reboot your computer. option-command-escape.

Hi,

I'm totally new to Python and Psychopy, pretty new to writing scripts. I've been using the builder mode, Psychopy 1.76.00, Mac OS X 10.6.8.

I was using Psychopy 1.74, and that didn't really work for me. Although I could run demos at first, I could never stop scripts by pressing "Cmnd+." nor "Esc". Basically, I could not stop scripts at all, so if a demo or my script was running, I just had to wait for it to finish or reboot my computer. I'm still experiencing the same issues, but now my scripts are running as well, whereas they did not run on Psychopy 1.76.00.

Thanks,

Phoebe

aaah, I see. Yes, I don't see any point in a key binding for that (and
hadn't realised/remembered there was one!)

also, Phoebe, try this: run the coder demo > input > what_key.py, press the esc key, and report back what it says. for me the output (in the coder output window) is ['escape']. if it does not say 'escape', then the usual default way to stop a script will not work for you.
