Triggering a Drupal 7 rule when an interactive content is solved
I want Drupal 7 to trigger a rule whenever a user successfully solves an interactive content node (he/she has scored full points). Drupal seems to store the user's score in a field, which is visible in the Results View of the node. But how can I trigger a rule when the score is awarded? I can't see any condition for comparing field values in the rules configuration section.
Or do I have to use the TinCan API? I've already set up the H5P TinCan Bridge, the TinCan LRS Server, but triggering a rule from TinCan seems pretty complex, so it'd be great if I could avoid TinCan.
