Joe - You can definitely create a report that tells the learner how they did in the game, but it's not automatically built for you. That's because, in a 3D game, the decisions and behaviours a player exhibits are often not related to questions - they are related to what's happening in the environment. That said, to create a report, use a variable node for each question or interaction. Then, at the end of the game, use the logic to do the arithmetic on the variables and give the learner feedback on how they performed.
In a recent game that we built, we had on-screen progress bars to indicate to the learner how they were doing in each of the following categories: Expertise, Analysis, Knowledge, and Decision Making. At the end of the game, we tallied each of the categories and gave feedback. For example, if the player amassed 0-50 points in a category, they received "low" feedback that we built in a conversation interaction. If they amassed 51-80 points, they received the "average" feedback. If they got 81-100, they received the "high" feedback.
If you need help building the report using the logic, please let me know!
