Translation is not very well for your question, so I am just guessing a little bit. I don't know what you mean by 'slide trailer'? Maybe post a screenshot. I understand something is not playing the same way as the first time when you return to the slide. Not sure what. By 'animation' do you mean an imported animatlion like OAM? Or is it an Effect created in Captivate? Adding a screenshot of the slide and the Timeline and indicate the object you do have issues with. Translated terminology in Spanish version of Captivate is totally unknown to me.
The problem occurs when revisiting a slide, as it redisplays the animation of the elements created with captivate.
Ideally, when returning to the slide, it should not show the animations of the elements again.
I have understood that from your original explanation but the terminology is not clear to me. Please post screenshots as I asked for. I want to see what you mean by 'animation of the elements' which you don't want on later visits. It probably can be done by navigation immediately to a later frame in the slide, based on a user variable which tracks the visits to that slide. That variable should be incremented On Enter of the slide, same as the navigation to a later frame. If you confirm my guesses by screenshots, will give you more details or point to a blog post like this:
animation of the elements' I refer to the effects of the elements in the timeline, if they were already played when starting that when returning to this same slide they are not played again.
Ideally, the slide should save the visited status.
It's clearer now!
You have a lot of effects, cannot see their duration but will try to explain how I would proceed, part of it I already mentioned:
Ok thanks, I will try to do it this way, it looks very complex.
There is the extra hurdle of the language of course. It is not that complicated, hope you tried to have a look at the introduction to Micro-navigation for which I posted a link before.
