BehaviorService

class

Core/Vixen.Ai/BehaviorTrees/BehaviorDecorator.cs:122

csharp

public abstract class BehaviorService

Something that runs on an interval for as long as a composite's branch is active.

Read the guide page for this →

Remarks

Where perception updates, target selection and blackboard maintenance go. A service is a local sensor with a schedule — doc 37 § D13 — which is why there is one implementation of "read the world into a key" and two front ends onto it.

Shared across agents like everything else here, so per-agent state is the span.

Fields and properties (1)

public virtual int StateSize
How many bytes of per-agent state it needs.

Methods (3)

public virtual void Enter(in BehaviorContext context, Span<byte> state)
The branch became active.
public abstract void Tick(in BehaviorContext context, Span<byte> state, float delta)
Its interval has elapsed.
public virtual void Leave(in BehaviorContext context, Span<byte> state)
The branch stopped being active.
