UActorComponent::GetComponentClassCanReplicate

function Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: virtualconst

Description

Returns true if this component class is allowed to replicate at all. Override and return false to permanently prevent a component type from ever being set as replicated, regardless of caller intent.

Caveats & Gotchas

• This is a class-level capability check, not an instance-level state — returning false here means no instance of this component class can ever replicate, even if SetIsReplicated(true) is called on it.
• The engine calls this in SetIsReplicated to silently discard replication requests; there is no warning or error when the request is rejected.
