restricted navigation, disabled Next button until all layers visited
I disabled the next button on the base layer when timeline starts (navigation is set to advance by the user and restricted in the player and next buttons restricted as well). The timelines on the other layers are very long and contain too much information but that's another topic. ;-) If there's a trigger to change state of next button if each of the buttons on the base being either selected or visited, then that control works for the player and next button navigation. However, the next button is normal immediately upon selecting whichever that last selected/visited button and the learner does not have to listen/seehe entire layer of whichever layer was triggered but whichever button was chosen last, and can skip past with the normal state next button. Basically, I don't want only a variable change to true on the state of all buttons being visited. I tried half dozen ways with variables and state changes and conditions on trigger of next button state change to normal.
I created a variable on each layer, which changes to true upon the timeline of each layer ending, (since there's no built-in trigger to change state of next button to normal when the layers have been visited). then I put the condition of the trigger on the next button state to normal if all the variables changed (each layer true at end of timeline). I swear this worked at some point and now does not.
This is a very complicated and time-consuming way to "restrict" navigation until all layers are visited and then allow user to advance. That's because the layers themselves aren't being controlled like the base layer.
what am I missing? your help is appreciated as I've spent too much time on this. I'm about to throw in the towel and let the learner skip past whatever they want to skip past if they want to. ;-)
