ACharacter::ClientAdjustRootMotionPosition_Implementation

function Engine Deprecated Since 4.6

Deprecated: Use ClientMoveResponsePacked_Implementation instead.

#include "GameFramework/Character.h"

Access: public

Description

The client-side implementation body for ClientAdjustRootMotionPosition, executed on the owning client after the RPC is dispatched. Override this to inject custom correction logic.

Caveats & Gotchas

• This is the _Implementation suffix counterpart of a deprecated RPC — override it only if you are maintaining legacy movement code targeting older engine versions.
• Must call Super to ensure the base correction logic (position snap and montage track seek) executes; omitting Super will silently break root-motion network correction.
• Deprecated alongside its RPC counterpart — new code should override the packed response implementation instead.

Signature

ENGINE_API void ClientAdjustRootMotionPosition_Implementation(float TimeStamp, float ServerMontageTrackPosition, FVector ServerLoc, FVector_NetQuantizeNormal ServerRotation, float ServerVelZ, UPrimitiveComponent* ServerBase, FName ServerBoneName, bool bHasBase, bool bBaseRelativePosition, uint8 ServerMovementMode)

Parameters

Name	Type	Description	Default
TimeStamp	float	Server timestamp of the move being corrected.	—
ServerMontageTrackPosition	float	Authoritative montage playback position.	—
ServerLoc	FVector	Corrected world location.	—
ServerRotation	FVector_NetQuantizeNormal	Corrected rotation packed as a normal vector.	—
ServerVelZ	float	Vertical velocity at the correction point.	—
ServerBase	UPrimitiveComponent*	Movement base component.	—
ServerBoneName	FName	Bone on the skeletal movement base, if any.	—
bHasBase	bool	Whether the character has a valid movement base.	—
bBaseRelativePosition	bool	Whether ServerLoc is base-relative.	—
ServerMovementMode	uint8	Packed movement mode.	—

Return Type

void

Example

Override to add telemetry before applying correction C++

void AMyCharacter::ClientAdjustRootMotionPosition_Implementation(
    float TimeStamp, float TrackPos, FVector Loc,
    FVector_NetQuantizeNormal Rot, float VelZ,
    UPrimitiveComponent* Base, FName BoneName,
    bool bHasBase, bool bBaseRel, uint8 Mode)
{
    RecordCorrectionEvent(TimeStamp, Loc);
    Super::ClientAdjustRootMotionPosition_Implementation(
        TimeStamp, TrackPos, Loc, Rot, VelZ, Base, BoneName, bHasBase, bBaseRel, Mode);
}
