Wait for specific cedrus key
 

My cedrus handler triggers an event viz.sendEvent(CEDRUS_BUTTON_DOWN, response['key']) every time a cedrus button is pressed.

How can I pause my Experiment until a specific cedrus key is pressed (e.g. button 6 is down)?

You can use viztask and the waitEvent command to wait for the cedrus button event.

But in this case every cedrus button resumes my experiment.
How can I wait for a specific button? (e.g. button 6)

Are you using the vizxid module to get the Cedrus data, like the example posted here? If so, you can wait for a specific button press:

I'm using pyxid. But I'll have a closer look at the implementation of waitButtonDown.
