UActorComponent::IsRegistered

function Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: inline

Description

Returns true if this component is currently registered with the world, meaning it is active, ticking (if enabled), and has its render and physics state initialized.

Caveats & Gotchas

• Returns false for components on CDOs (class default objects) and components that have been created but not yet registered — always check this before performing world-interaction operations like physics queries.
• A component can be unregistered but still attached to an actor. `IsRegistered()` and `IsAttachedToActor()` are independent states.

Signature

inline bool IsRegistered() const { return bRegistered; }

Return Type

bool

Example

Guard world access with registration check C++

void UMyComponent::DoWorldQuery()
{
    if (!IsRegistered())
    {
        return;  // Component not yet active in the world
    }
    UWorld* World = GetWorld();
    // Safe to use World here
}
