How to give a feedback by drawing the area that our participant clicked at?

So we 2 pictures and we want out participants to find differences between them. We want them to click on those differences one by one. And in each correct time we want to display a little red circle showing the area they clicked. Is there a way to do that? Can anyone help with this task? Thank you in advance.

Hi @elifff, a rough idea:

  1. Already put the circles into the correct locations, but set them to be fully transparent.
  2. Check every frame, if a circle has been clicked. If so, set it to be not transparent anymore.

Hope that helps you to get started.
