AActor::FinishAndRegisterComponent

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public

Description

Completes component setup by adding it to the actor's serialized components array and registering it with the world. Called at the end of CreateDefaultSubobject-style construction paths.

Caveats & Gotchas

• This adds the component to the OwnedComponents and BlueprintCreatedComponents lists — do not call it on components that were already registered through another path or they will appear twice.
• Must only be called during an actor's construction phase (constructor or OnConstruction). Calling it after BeginPlay can produce components that are partially initialized and unserialized.
