Behavior Trees (BTs) are a powerful tool for structuring complex decision-making processes in AI and game development. They provide a visual and hierarchical way to organize behaviors, making them easy to debug and modify.

Core Concepts 🧠

  • Nodes: The building blocks of a behavior tree, including:
    • Root: The top-level node that starts the tree execution.
    • Decorator: Modifies the behavior of child nodes (e.g., Inverter, Random Selector).
    • Composite: Manages multiple child nodes (e.g., Sequence, Selector, Parallel).
    • Leaf: Executes specific actions (e.g., Move Forward, Attack).
  • Tree Structure: A hierarchical graph where nodes are connected to form logical flows.

Applications 🕹️

  • Game AI: Control non-player characters (NPCs) with dynamic decision-making.
  • Robotics: Manage sensor inputs and actuator outputs in autonomous systems.
  • Automation: Streamline repetitive tasks in software engineering.
