Hello everyone! Please forgive me if this has been answered before, I’ve hunted through the forum and couldn’t find this issue.
I’m programming a button choice experiment with two button, on the right and on the left. When the participant presses the right arrow key, it selects the right-hand button on the screen` when they presses the left arrow key, it selects the left-hand button on the screen.
I want a number to appear on the button they selected. Pretty straightforward, right? But for some reason, I can’t make this work! The button on the left disappears no matter which button I press - the if condition isn’t working. The output file shows that the key presses are being received and save correctly by Psychopy.
I inserted this code component:
if key_resp_1.keys == 'right': rightB.opacity = 0 leftB.opacity = 1 else: leftB.opacity = 0 rightB.opacity = 1
I receive this error:
UnicodeWarning: Unicode equal comparison failed to convert both arguments to unicode, interpreting them as being unequal.
I have tried all sorts of things to encode either the keyboard’s input or the ‘right’ string in the comparison, and debugging shows that I have successfully encoded them as either ascii or unicode, but the error keeps appearing.
Does anyone have any idea why this is happening? Am I using the keyboard component incorrectly?
