AActor::IsAttachedTo

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: virtual

Description

Walks up the component attachment chain to determine whether this actor is attached (directly or transitively) to the given actor.

• This checks component attachment, not movement base (standing-on) relationships. For character movement scenarios where a pawn stands on a non-attached base, use IsBasedOnActor instead.
• The search traverses the full parent attachment chain upward, so it is O(depth) rather than O(1). Avoid calling it every frame for many actors.
