Using buttons to move between "tabs"
I have a course that is broken out into modules and each module is broken into five topics. I have it structured so that users can navigate back and forth between different topics by using a set of shapes along the bottom of the window, each set to navigate to a new slide when clicked. I wasn't able to set it up like a tabbed interaction on one slide because each topic will have several layers and it would have gotten extremely unruly.
The problem I'm running into is that when a user navigates through the topics in order I have the states on the shapes set to change to show that they have already completed the topic (see the states in the image, the transparency is set differently for "visited" ). I get into trouble when my users try to go out of order. I would like for them to be able to be on the first topic, click on the last topic to navigate to that slide, click to navigate to the third topic from the last topic's slide, then come back to the first slide and the other two topics that are completed are in their "visited" state.
I know I can't set a trigger to change the state based on a click that happened on another slide, and I've been trying to do it with variables for a while with no luck. Can anyone walk me through this?
