AiFocus

Remarks

Unreal's focus, and its value is that everything downstream reads one place. A rotation task, an aim offset, a head-look constraint and a dialogue camera all want "what is this character looking at", and without a component for it each of them takes its own blackboard key and they disagree the first time one branch sets a key another does not.

⚠ An entity or a point, and the entity wins. A focus on an entity follows it as it moves; a focus on a point does not. Two fields rather than a discriminated one because Null already means "there is no entity", so the tag would be a second copy of a fact the value carries.

Fields and properties (3)

• public Entity Target

  What it is looking at, or Null for Point.

• public Vector3 Point

  Where it is looking, when there is no target.

• public bool HasFocus

  Whether it is looking at anything at all.

Methods (3)

• public readonly bool TryResolve(World world, out Vector3 position)

  Where the focus is now, following the target if there is one.

• public static AiFocus On(Entity target)

  A focus on an entity.

• public static AiFocus At(Vector3 point)

  A focus on a place.
