UBehaviorTreeComponent::GetActiveNode

function AIModule Since 4.0

#include "BehaviorTree/BehaviorTreeComponent.h"

Access: public Specifiers: const

Description

Returns the currently executing node in the active instance on top of the stack — typically the task currently running.

Caveats & Gotchas

• Returns null if the instance stack is empty; a running tree with no active task briefly during a search can also momentarily reflect a stale value until the search completes.
• The returned node is a const pointer — use IsExecutingBranch or FindInstanceContainingNode instead if you need to reason about ancestry rather than just the leaf.
