UActorComponent::IsNetStartupComponent

function Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: const

Description

Returns true if this component was owned by a net startup actor during level load. Net startup components can be reliably referenced by name across the network.

Caveats & Gotchas

• This flag is set by the engine during ULevel::InitializeNetworkActors and should never be set manually by game code — use SetIsNetStartupComponent only if you are writing engine-level initialization code.
• Only components on net startup actors (actors placed in the level at edit time that replicate) have this set to true. Dynamically spawned actors and their components will always return false.

Signature

bool IsNetStartupComponent() const { return bIsNetStartupComponent; }

Return Type

bool

Example

Check if a component is a net startup component C++

if (MyComponent->IsNetStartupComponent())
{
	// Component is addressable by name on clients — safe to reference by stable name
	UE_LOG(LogNet, Verbose, TEXT("%s is a net startup component"), *MyComponent->GetName());
}
