AActor::SetReplicateMovement

function Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintCallablevirtual

Description

Controls whether this actor's movement (location, rotation, velocity) is replicated from server to clients. The actor must also have replication enabled via `SetReplicates`.

Caveats & Gotchas

• Setting `bReplicateMovement` without also having `bReplicates = true` has no effect — movement replication piggybacks on the general replication channel.
• Movement replication uses the `ReplicatedMovement` struct (FRepMovement), which sends smoothed/compressed data. It is not a perfect mirror of server transforms — clients apply correction smoothing. If pixel-perfect authority sync is required, use a custom RPC.
• Disabling movement replication does not stop a Character's CharacterMovementComponent from simulating locally on clients — only the server-authoritative sync is turned off.
