Locating randomised Radio and Check Mark buttons

It sounds like you're dealing with a tricky issue due to the shuffle answers feature. One approach could be to dynamically track the randomized positions of your buttons using a variable or array that updates when the slide randomizes. This way, you can map the hidden buttons to their new positions without turning off randomization. As for the intersection method causing the slide to stop playing, it might be worth checking if the state change or object interaction is interrupting the slide's timeline—perhaps adding a condition to delay the state change until after the slide starts could help. Have you tried logging the button positions to see if that gives you a clue? I'd be curious to hear if others have a similar setup!

That sounds like a mind-bending one to solve!

I don't think there's a way to read where something ends up once it's been positioned randomly, but I'm happy to be corrected.

Have you tried grouping your custom button and the text with the associated hidden button beneath it? You could then try selecting the whole group as the correct/incorrect option within the Question Editor and then use your Triggers to make the relevant hidden button visible depending on the answer that's been selected.

No guarantees it'll work, but off the top of my head it seems like it's worth a try.

You might be able to track the object IDs

But realistically for a sustainable solution I would rebuild as a freeform

I’m not sure what your current setup is, but it shouldn’t matter whether you’re using a graded question, a freeform interaction, or a fully custom layout. The real challenge is detecting the position of an object when the answers are shuffled.

To handle this properly, you’d need to use JavaScript and reference objects directly, so that elements like a checkmark or tick icon align to the correct option, ideally when it’s selected or represents the correct answer.

In the example below, I used a bit of JavaScript to align a single checkmark with whichever object is currently selected, even when the answer order is randomized. It's done using a simple script, without any triggers, just a single "Execute JavaScript" trigger that runs when the object is selected. Even if the objects are randomly scattered or repositioned on the slide, the code doesn't need to be updated. It will execute the same way.

I used a similar technique in E-Learning Challenge #506.

Again, I’m not sure of your exact scenario. How many objects are involved or what your full requirements are but if the main goal is to detect an object’s position and align another object to it, then yes, this can definitely be done.
