Change opacity of the shape to reveal the text on mouse click

Builder

I need to reveal the text under an image with a mouse click. What are the steps to change the opacity of the shape on click that covers the text in Builder (or in Code, though I am a novice)?

**OS Win11
**PsychoPy version 2022.2.4

Hi @Dasha_Mesquita,

if you have an image component image_stim and a mouse component mouse, you can add a code component to your routine and have

Each frame

if mouse.isPressedIn(image_stim):
    image_stim.opacity = 0

@ajus, I did what you suggested and had this error. Do you have any idea what it means and what to do with this?

This seems to have nothing to do with the code. In your loop “trials_LLAMA_B” the nReps field seems to be empty. It must contain the number of repetitions you need.

Thank you so much! I fixed it and everything is working!)) I was wondering if you could help me with another question. I tried to find the solution online but I am not even sure how to formulate my question)
I want people to click, see a word for several seconds, then the word disappears, and to see it again a person needs to click once more.

I forgot to add, that I need to have several clickable images on the screen. (maybe that is important)

So the timeline would be: I click an image, and it disappears to reveal a text. After some time (how long?) the text disappears, I click again (where?), and the text reappears. Right?

How should it work with different images? Can I click all images? Or just one? Do they all do the same thing independently from another?
