AActor::NetTag

property Engine Since unknown

#include "GameFramework/Actor.h"

Access: public Specifiers: UPROPERTYTransient

Description

Internal bookkeeping integer used by UNetDriver to track actor channel state. Do not read or write this from gameplay code.

Caveats & Gotchas

• This property is an engine-internal implementation detail of the net driver's actor relevancy and channel tracking system. Modifying it directly can cause silent channel desynchronisation and replication failures that are extremely difficult to diagnose.
• Marked Transient so it is never serialised to disk — its value is only meaningful within a single net driver session and is reset when the connection is torn down.
• It is exposed as public solely to allow the engine's net driver code to access it efficiently; this does not imply it is intended for external use. Treat it as if it were private.

Example

Never do this C++

// DO NOT modify NetTag directly — this is for illustration only
// Actor->NetTag = 0; // Resets internal net driver tracking, causes replication bugs
// Instead, let the net driver manage this automatically.
