ACharacter::PreNetReceive

function Engine Since 4.0

#include "GameFramework/Character.h"

Access: public Specifiers: virtualoverride

Description

Called on the client immediately before applying an incoming network update for this Character. ACharacter uses this to snapshot the replicated gravity direction so post-receive logic can detect changes.

Caveats & Gotchas

• Only executes on clients (simulated and autonomous proxies) — never called on the authoritative server.
• Do not apply gameplay logic here that assumes the new values are already committed; the replicated properties have not been written yet when PreNetReceive fires.

Signature

ENGINE_API virtual void PreNetReceive() override;

Return Type

void

Example

Snapshot a replicated value before replication overwrites it C++

void AMyCharacter::PreNetReceive()
{
    Super::PreNetReceive();
    // Cache old value so PostNetReceive can diff against the incoming one
    OldReplicatedState = CurrentReplicatedState;
}
