How do behavior trees work in C++ game AI design?

Behavior trees are a hierarchical model used to control AI behavior in games. They consist of nodes that represent tasks, conditions, and actions, allowing for complex decision-making.

Can you explain the structure of a behavior tree?

Sure! A behavior tree is made up of nodes: composite nodes (like sequences and selectors), decorator nodes (which modify behavior), and leaf nodes (which are the actual actions or conditions).

What are the advantages of using behavior trees over finite state machines?

Behavior trees offer more flexibility and reusability compared to finite state machines. They allow for easier debugging and can represent complex behaviors more intuitively.

How can I implement a simple behavior tree in C++?

You can start by defining a base class for nodes, then create derived classes for different node types. Implement the tick function to evaluate and execute the nodes based on their types.
