ACharacter::RepRootMotion

property Engine Since 4.6

#include "GameFramework/Character.h"

Access: public Specifiers: UPROPERTYReplicatedUsing=OnRep_RootMotion

Description

Replicated struct that carries root-motion montage state from the server to simulated proxies. Updated each frame by PreReplication when an animation-root-motion montage is active.

Caveats & Gotchas

• Do not write to this field directly outside of the engine's replication path — use SetRepRootMotion or the movement component's correction RPCs instead. Modifying it manually can desync client simulation.
• The field is only meaningful on simulated proxies and is ignored on autonomous proxies, which drive their own root motion from local input.
• OnRep_RootMotion fires when this changes; hook that rep-notify rather than polling the struct if you need to react to root-motion state changes on clients.

Signature

UPROPERTY(ReplicatedUsing=OnRep_RootMotion)
struct FRepRootMotionMontage RepRootMotion

Example

Read montage position from the replicated struct C++

// On a simulated proxy, inspect the replicated montage position
const FRepRootMotionMontage& RMData = GetRepRootMotion();
if (RMData.bIsActive)
{
    float Position = RMData.Position;
}
