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.
