Next/previous buttons

Hi, John,

It sounds like you don't want a user to be able to click the built-in Next button in the Player until after they have viewed all the layers in a slide. If that is what you're asking about, the solution is to disable the Next button until the layers have been viewed. Here's how to do that:

• Create a T/F variable with a default value of False.  
• Add a slide trigger that changes the state of the Next button to Disabled when the timeline starts with the condition that the value of the variable = False. 
• Add a trigger that changes the state of the Next button to Normal when the user has viewed all the layers. There are different ways to determine if the layers have been viewed.
  • If the user clicks a button to view each layer (like in a tab interaction), then change Next to Normal when all those buttons reach the Visited state. 
  • If the user if forced to go through the layers in a specific sequence, then change Next to Normal on the last layer. 
• Add a trigger that adjusts the value of the variable to True when the user has viewed all the layers.

If you're using a custom Next button, you could control it the same way.
