AActor::GetActorClassDefaultComponent
#include "GameFramework/Actor.h"
Access: public
Specifiers: static
Description
Returns the first CDO component of a given type from the actor class, including Blueprint-added components. Returns nullptr if none is found. Use the templated overload `GetActorClassDefaultComponent<T>()` to avoid an explicit cast.
Caveats & Gotchas
- • Returns only the first match. If an actor has multiple components of the same type and order matters, use GetActorClassDefaultComponents to retrieve all of them.
- • The returned pointer is a const reference to a CDO template object. Storing it across Blueprint recompiles or hot-reload events may result in a dangling pointer in the editor.
