How to lock visited markers in 360 degrees image?

I'm assuming that the marker is showing a layer when clicked. 

• I'd create a T/F variable for each question.
• Create a "you already answered that" layer
• You can use a T/F variable to track if they answered the question.
  • Example: varQ1answered = F. Adjust var to true when the quiz question layer is accessed.
• With the T/F variable you can trigger the marker to go to the question layer on the condition that the var = False, else go to the "answered" layer

Something like that

Here's something I mocked up. I added quiz questions (instead of layers) and then link to lightbox slide. The file is attached.

There's a lot to learn :)

• I'd watch some of the training we have on variables and quizzing.
• https://training.articulate.com/webinars/getting-started-with-variables-in-storyline-360
• https://training.articulate.com/webinars/using-true-false-variables-in-storyline-360
• https://training.articulate.com/webinars/getting-started-with-quizzes-in-storyline-360

I used lightbox slides because it allows me to use the built-in quiz questions. You can pull scores from the quiz questions using the results slide (see video above).

I'm not sure what you mean by prevent skipping the question with the cross button. But the variables conditions aren't met until all question variables are true, so you have some way to track the user and provide feedback and instructions based on that.

I'll record a quick tutorial to get you pointed in the right direction. 

OK, I created a tutorial and showed how to use layers or quiz questions (two ways). Hopefully that helps.
