I am new to Captivate. I have a next button on first slide with audio file. I need the next button to be disabled when slide opens and next button enabled when audio file completes, so that user can click to go next slide. Could you please advise.
If there are no other interactive objects on that slide, you can use the On Enter event of the slide with this advanced action:
Delay Next Actions by x seconds where x is the duration of the audio clip in seconds
Continue is necessary to prevent the playhead from pausing at the first frame which could impact the slide audio if it is not starting on the first frame. Be careful: make the slide longer than the audio timeline, so that the playhead will not get inadvertently to the next slide before the Next button is enabled.
I answered your question literally, but honestly it is more friendly (and easier) to hide the Next button until the audio clip is almost finished. That can be done by having the start of the Next button timeline slightly before the end of the audio clip timeline.
You have liked my answer recently, but did it help you to solve the problem? If yes, please can you mark the answer as being correct?
