AActor::OwnsComponent
#include "GameFramework/Actor.h"
Access: public
Specifiers: const
Description
Returns true if the component is present in this actor's OwnedComponents set. Intended as a validation helper in assert/check contexts.
Caveats & Gotchas
- • This function is only compiled when `DO_CHECK` or `USING_CODE_ANALYSIS` is defined. In Shipping builds the function does not exist — code that calls it must be wrapped in `#if DO_CHECK` or it will fail to compile in Shipping.
- • Returns false for components that are owned by a child actor inside a ChildActorComponent, even though those components are logically 'part of' this actor hierarchy.
- • Use only for debug assertions, not for runtime logic. Prefer checking `Component->GetOwner() == this` for runtime ownership tests.
