AActor::CallPreReplication

function Engine Since 4.13

#include "GameFramework/Actor.h"

Access: public

Description

Called by the networking system to invoke PreReplication on this actor and all of its replicated components. Engine-internal; do not call directly from gameplay code.

Caveats & Gotchas

• Calling this from gameplay code is unsupported and can corrupt the tracker state — the engine drives it at the correct point in the replication tick.
• It respects the bCallPreReplication and bCallPreReplicationForReplay flags; overriding PreReplication without setting those flags means CallPreReplication will skip your override.
• Components must have their own PreReplication overrides if they need to set conditional properties — this function iterates components automatically.
