Custom forward/back controls
Hi folks. Apologies in advance if this has been answered elsewhere. I am creating a training with custom navigation controls "in-slide" (not default player "prev/next" buttons). The client wants to be able to control the user's navigation options when it comes to moving back and forward in the training. Particularly, we want to limit the "forward" button so that a user can only advance forward as far as they have already progressed in the training. That is to say, if they have viewed slides 1-10 of a 20-slide scene, they should be able to click back to slide 3 to check something they missed. Once they do, they should then be able to quickly click forward to return to their current position (slide 10). But we don't want them to be able to skip ahead using the forward button through slides they haven't yet watched/completed.
It seems that we could accomplish this using a variable with a trigger on each slide to keep track of the user's progress, but I'm curious if anyone has any other suggestions or tricks they've used in a similar situation. Copying and pasting triggers on around 200 slides seems tedious, and I'm wondering if there's a better way.
