send_command() causes TypeError when used with EyeTribe eyetracker

[dschreij]

When calling the exp.pygaze_eyetracker.send_command() from OpenSesame when the tracker type is EyeTribe, the program quits with the following message:

Error while executing inline script
phase: run
item: stimulus_display
line: 603
exception message: request() takes exactly 4 arguments (2 given)
exception type: TypeError

Traceback (also in debug window):

Hi Daniel,

Thanks for this! What command are you sending?

Cheers, Edwin

I think this was my bad (but this bug is still valid). I actually wanted to log a message and thus should have used the .log() function, but I think this function would also have crashed when sending a real command (as the argument count seems to mismatch). In short, I was not really trying to send a command ;)

Ah, I see where it went wrong. The send_command passes a tuple/list to request, whereas this expects the unpacked contents. Woops!

Thanks for finding out!
