UActorComponent::HasBeenInitialized

function Engine Since unknown

#include "Components/ActorComponent.h"

Access: public Specifiers: inline

Description

Returns true after InitializeComponent has been called and before UninitializeComponent has been called. Reliable indicator that the component's gameplay subsystems are ready.

Caveats & Gotchas

• Only returns true when the component has bWantsInitializeComponent set to true AND InitializeComponent has already executed; components with bWantsInitializeComponent == false will never flip this flag.
• UninitializeComponent is called inside AActor::EndPlay before the component is destroyed, so this can return false while the component object still exists — guard any EndPlay logic accordingly.

Signature

bool HasBeenInitialized() const { return bHasBeenInitialized; }

Return Type

bool

Example

Checking initialization before calling subsystem APIs C++

void UMyGameComponent::Tick(float DeltaTime)
{
    Super::Tick(DeltaTime);
    if (!HasBeenInitialized())
    {
        return; // subsystems not ready yet
    }
    UpdateInternalState();
}
