Disable Next Button on a Slide until all Buttons are Visited
This example illustrates how to disable next button when the timeline starts and enable next button when a variable change occurs after all of the slide buttons/objects have a state change to visited.
Note: All buttons must have a visited state. The next button will be enabled if the slide is revisited.
Create a True/False variable for the slide objects visited (SlideNumb_Action_VariableType).
Variable Name, Type = True/false, Default Value = False
Create a trigger that changes the next button to disabled when the timeline starts if the variable is not equal to true.
Adjust the variable when the identified slide elements change to a visited state.
Change the state of the next button to normal when variable changes.
