Smart Ant - Building AI Behavior with State Tree and Smart Objects

Explore how to build scalable, modular AI behavior in Unreal Engine using State Tree and Smart Object systems in this 44-minute conference talk from Unreal Fest Bali 2025. Discover how GameplayStateTree, Gameplay Interaction, and Game Features plugins work together to enable multiple developers and designers to efficiently iterate on AI behavior in parallel. Learn practical implementation techniques through the Antopia interactive project example, developed by S1T2 in 2024, which demonstrates real-world application of these systems. Understand the setup process, implementation strategies, and key strengths and limitations of combining State Tree and Smart Objects for AI development. Gain insights into how these systems streamline development workflows and enhance team collaboration between designers seeking flexibility and developers aiming for cleaner AI logic. Review the major updates introduced in Unreal Engine 5.5 that improve accessibility and functionality of these AI behavior systems, with practical examples and lessons learned from S1T2's development experience.
