UActorComponent::OnDestroyedFromReplication

function Engine Since unknown

#include "Components/ActorComponent.h"

Access: public

Description

Called on clients when a replicated component is removed from the network. Part of the IInterface_ActorSubobject protocol — handles teardown of the component's replicated state on the receiving end.

Caveats & Gotchas

• Only fires on clients (or listen-server proxies) — never on the authoritative server. If you override it to release resources, ensure your cleanup logic is safe to call in a non-authority context.
• This is paired with OnCreatedFromReplication. Both are internal replication hooks; override them only if your component manages replicated subobjects or needs custom teardown on the client side.

void

Example

Cleaning up client-side state when a replicated component is removed C++

void UMyReplicatedComponent::OnDestroyedFromReplication()
{
    // Release any client-only resources tied to this component's replicated lifetime
    ClientSideParticleSystem = nullptr;
    // Always call Super — it handles core replication teardown
    Super::OnDestroyedFromReplication();
}
