Locking down navigation in Storyline 360

If more than one interactive element you could use variables (True/False) to disable all interactive elements until the audio associated with the currently clicked button finishes playing.

1. Create a True/False Variable:

Name it something like audioPlaying.

Default value: False.

2. Set the Variable When Audio Starts:

Add a trigger to each interactive button:

Set variable audioPlaying = True

When user clicks [button]

3. Disable Other Clicks While Audio is Playing:

For each interactive object (button), add a condition to its trigger:

Play media [audio file]

When user clicks [button]

If audioPlaying = False

4. Reset the Variable When Audio Ends:

Add a trigger to each audio object:

Set variable audioPlaying = False

When media [audio file] completes

You can also build in Visual Feedback

To improve UX, you could disable buttons visually while audio is playing:

Create a "Disabled" state for each button.

Add a trigger:

Change state of [button] to Disabled

When variable audioPlaying changes

If audioPlaying = True

And another to re-enable:

Change state of [button] to Normal

When variable audioPlaying changes

If audioPlaying = False

Do this for each Button/Audio Pair

It ensures:

Only one audio plays at a time.

Users can’t interact with other elements until the current audio ends.

This way you have more control over pacing and ye give focused learning.
