Hello!
I am trying to buil a memory test. It is a 4x4 Grid (16 positions) and show between 3 and 8 squares randomly on the screen at random positions. The number of stimuli should change randomly on each trial. Right now i can only produce a Grid with all the possitions filled or blank (opacity 1/0). I want the stimulus to be shown in a random sequence. I saw other posts about this topic but i still could not achieve the desired results.
In my builder, i have a image of a grid, and 16 polygons.
I am new with psychopy. I was able to do a digit and word recall before, but that is my whole knowledge so far.
Thank you in advance for your help
