Mirror images

I used to use negative width to present a mirror image of a visual stimulus. Unfortunately, this stops the stimulus being clickable with a mouse online.

Instead, use flipHoriz in a code component. For example,

if trials.thisN%2:
    image.flipHoriz = True
else:
    image.flipHoriz = False

Try it

The polygon fix is to have an invisible polygon to click on instead.
