Is there a way to fade audio with Storyline 3?

I saw this post from a few years ago, but the link to the demo seems to be disabled: [DEMO] Dynamic Fade In & Out using SM2 background audio

Hi Elizabeth,

Thanks for your response. The information in the threads is very helpful. Unfortunately, my agency has massive firewalls built to where I cannot access any type of software on the internet. I'll have to reach out to my Security dept. to see if I can get special permission to download Audacity or some other audio editing tool. Oh yeah, Windows Movie Maker has been disabled also. 

So, I'll keep you posted. 

Thanks, again!

Follow up to Elizabeth,

I was able to get Audacity installed, so I'm good. Thanks.

Now, I have a new issue. I have a slide where there are six layers that need to be visited before users can click NEXT. My triggers effectively disable and reenable the NEXT button, but if a user moves to a new slide and revisits that slide, only the disable trigger works and the NEXT button remains disabled. The buttons on the slide don't reset to being "un-visited" either.

I saw a similar question in an earlier thread and the answer was to add a condition, but for the life of me, I don't understand the language of conditions. I am a new user to Storyline (using version 3) so this is all still Greek to me, lol,

Ok, thanks for any help you can give, even if it's pointing me in the direction of a tutorial along the lines of "Storyline Conditions for Dummys." (which is not an exaggeration of my understanding of them right now, lol)

Hi there, Enya! No dummys here – completely an exaggeration! Conditions add another layer of complexity to triggers. They let triggers know to fire only if the conditions are right. We're happy to help!

My guess is that your trigger to change the state of the Next button back to Normal is when the "state of all of X, Y and Z, etc" are visited. The trigger to change the Next button to disabled is timed for when the timeline starts with no condition. Is that accurate?

When you return to the slide, those objects aren't changing to Visited again, so there is no "action" to trigger the Next button to change to Normal. Try adding a condition to the trigger changing the Next button to disabled so it only happens IF the state of X isn't normal, OR if the state of Y isn't normal, OR if the state of Z isn't normal, etc. You'll probably need 6 conditions.

Let me know if you have any questions!

Yes, you're correct about when the Next button turns normal and disabled. But, when you return to the slide, the objects remain visited, they don't change back to un-visited, yet, the Next button returns to disabled (since the timeline has restarted.) Even though the timeline has restarted, the six buttons don't respond. I understand HOW conditions work with triggers, just not the language to actually program one. Is there a list of commands somewhere that explain how to use them for specific functions? I hope that question makes sense.

Hi Enya,

Thanks for the additional information.

It sounds like you have a firm grasp on how triggers and conditions work, so I'm curious if the trigger order may be the issue or if you just need an additional trigger for the button when the timeline restarts?

With your permission, I'd like to take a look at your project file to investigate what's happening. You can share it publicly here, or send it to me privately by uploading it here. I'll delete it when I'm done troubleshooting.
