How do behavior trees work for NPCs in C++ games?

Behavior trees are a way to model the decision-making process of NPCs. They consist of nodes that represent tasks, conditions, and control flow.

Can you explain the different types of nodes in a behavior tree?

Sure! There are mainly three types of nodes: Action nodes, Condition nodes, and Control nodes. Action nodes perform tasks, Condition nodes check for certain conditions, and Control nodes manage the flow of execution.

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

To implement a behavior tree in C++, you can start by creating a base class for nodes, then derive specific node types. You'll need to define how each node executes and how they interact with each other.

What are some common use cases for behavior trees in games?

Common use cases include enemy AI, companion NPCs, and dynamic event responses. They help create more realistic and adaptable behaviors.
