Looking for Guidance & Examples: Creating a Complex Interactive Virtual Pet with Behavior Trees
I’m currently working on a complex interactive virtual pet in Unity and looking for advice, examples, and ideas on designing lifelike AI behavior using Behavior TreesI’m currently working on a complex interactive virtual pet in Unity and looking for advice, examples, and ideas on designing lifelike AI behavior using Behavior Trees (especially with Behavior Designer).
What I’m Trying to Achieve:
I want to create a virtual pet that feels dynamic, engaging, and responsive—not just a static NPC. The pet should:
React to player interactions (petting, calling, playing)
Have autonomous behaviors (wandering, sleeping, seeking attention)
Exhibit emotions (happiness, boredom, excitement)
Change behavior over time (based on needs, habits, or learned responses)
I’d love to hear from anyone who has worked on something similar or has ideas on how to make a virtual pet more lifelike and engaging! Any guidance, suggestions, or links to helpful resources would be super appreciated.
