AI Arborist - Proper Cultivation and Care for Your Behavior Trees

Explore core principles for optimizing behavior trees in game development while avoiding common pitfalls in this 2017 GDC talk. Learn about node decorators, interruptions, tree splitting, smart objects, behavior prioritization, and extending behavior trees. Discover techniques for daemon behaviors, message passing, behavior locking, and augmenting behavior trees with external plan generation and goal formulation. Gain insights into practical examples like retry mechanisms, look-at functionality, debugging strategies, and unit subtasks to enhance AI decision-making in games.
