I’m new on PsychoPy (v2021.2.3) and have some troubles with Textbox and/or coder.
In my experiment there is a Routine with Text (for instructions), a Textbox Beta (to type an answer), a coder (to define allowed keys) and a keyboard (to end the routine by press “space”)
Participants have to guess how many seconds they have seen a polygon before and should type numbers and even decimal places. That’s why I can’t use the keyboard only because it would force the end of routine. So I found a code in a forum to define multiple allowed keys for Textbox:
each Frame:
textboxvp.text = “”.join([ch.upper() for ch in textboxvp.text if ch.lower() in [“1”,“2”,“3”,“4”,“5”,“6”,“7”,“8”,“9”,“0”,"."]])
The experiment works but sometimes keys only react after pressing several random numbers. e.g if I want to type “4” the number 4 does not react and I have first to press several other numbers until one appear.
Unfortunately I can’t see any pattern why it sometimes works proper and sometimes not and it seems totally random which numbers I have to press until any appear. Same problem also on other Laptops, not only on mine (macOS Big Sur).
I would be very grateful for any advice.
Thank you!
you could use code only to register the response.
Begin routine tab
text.text = ''
event.clearEvents('keyboard')
Each frame
keys = event.getKeys()
if len(keys):
if 'backspace' in keys and len(text.text):
text.text = text.text[:-1]
elif ('return' in keys or 'num_enter' in keys) and text.text != '':
continueRoutine = False
elif 'minus' in keys or '-' in keys or 'num_subtract' in keys or 'Minus' in keys or 'slash' in keys:
text.text = text.text+'-'
elif '1' in keys or 'num_1' in keys:
text.text = text.text+'1'
elif '2' in keys or 'num_2' in keys:
text.text = text.text+'2'
elif '3' in keys or 'num_3' in keys:
text.text = text.text+'3'
elif '4' in keys or 'num_4' in keys:
text.text = text.text+'4'
elif '5' in keys or 'num_5' in keys:
text.text = text.text+'5'
elif '6' in keys or 'num_6' in keys:
text.text = text.text+'6'
elif '7' in keys or 'num_7' in keys:
text.text = text.text+'7'
elif '8' in keys or 'num_8' in keys:
text.text = text.text+'8'
elif '9' in keys or 'num_9' in keys:
text.text = text.text+'9'
elif '0' in keys or 'num_0' in keys:
text.text = text.text+'0'
