Navigation requirements: First restricted - next button is only available at the end of the timeline; second free navigation
“Useable at the end of the timeline” probably is not a good idea, because it may become useable before some of the learners finish.
Create a T/F variable (Interaction1Completed, e.g.) for each interaction, with a default of False.
For each interaction create a trigger (“Change variable InterractionXCompleted set to True when [action that indicates interaction X is completed]”
If the interactions are all on one slide, create a trigger “Change state of Next Button to Normal when variable InteractionXCompleted changes if Interaction1Completed = True, AND Interaction2Completed = True, AND Interaction3Completed = True”, etc.
If the interactions are on different slides, create a trigger “Change state of Next Button to Normal when timeline starts on this slide if Interaction1Completed = True, AND Interaction2Completed = True, AND Interaction3Completed = True”, etc.
Create a trigger “Change state of Next to Hidden (or Disabled) when timeline starts on this timeline if Interaction1Completed = False, OR Interaction2Completed = False, OR Interaction3Completed = False”, etc.
