UActorComponent::GetAssetUserDataOfClass

function Engine Since 4.14

#include "Components/ActorComponent.h"

Access: public Specifiers: virtualoverride

Description

Returns the `UAssetUserData` instance of the specified class attached to this component, or null if none exists.

Caveats & Gotchas

• Returns null if no data of that exact class has been added — always null-check the result before use.
• Lookup is by exact class; a subclass instance registered under a parent class type will not be returned when querying by the parent class.
