In this update we show how a variety of interactions can grow a relationship. And new ones become available as you increase or decrease the stages of the relationship. Repetition doesn't work in relationships, so I had to retool the NPC brain to be able to efficiently store and quickly retrieve everything that happens to them (with timestamps) so they can react correctly to someone spamming the same choices.
Then we do something we never did before: about half way through the video we dive into the code and show some of the efficiency gains from the refactoring. We hope this is of interest to developers out there.
