AActor::GetInstanceComponents

function Engine Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: const

Description

Returns a read-only reference to the array of components that have been added to this actor instance at runtime via AddInstanceComponent.

Caveats & Gotchas

• The returned array only contains components tracked via AddInstanceComponent — it does not include native components defined in the constructor or Blueprint-created components stored in BlueprintCreatedComponents.
• Do not cache the returned reference across frames; the underlying array can be mutated by Add/Remove/Clear calls, invalidating any cached pointer or iterator.

Signature

ENGINE_API const TArray<UActorComponent*>& GetInstanceComponents() const

Return Type

const TArray<UActorComponent*>&

Example

Iterate over all instance components C++

for (UActorComponent* Comp : GetInstanceComponents())
{
    if (UStaticMeshComponent* Mesh = Cast<UStaticMeshComponent>(Comp))
    {
        Mesh->SetVisibility(false);
    }
}
