UCharacterMovementComponent::ServerMoveOld

function Engine Deprecated Since 4.0

Deprecated: ServerMoveOld() is deprecated, use ServerMovePacked_ClientSend() instead, or define SUPPORT_DEPRECATED_CHARACTER_MOVEMENT_RPCS=1 in the project and set CVar p.NetUsePackedMovementRPCs=0 to use the old code path.

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtualENGINE_API

Description

Legacy replicated function for resending an important old move so the server can process it if it hasn't already been received.

Caveats & Gotchas

• Deprecated since UE 4.26 in favor of the packed movement RPC path (ServerMovePacked_ClientSend); only compiled in when SUPPORT_DEPRECATED_CHARACTER_MOVEMENT_RPCS=1 and p.NetUsePackedMovementRPCs is 0.
• Part of the legacy fixed-parameter RPC family alongside ServerMove and ServerMoveDual — all three were replaced by the single variable-length packed RPC.
• New projects should not implement against this; it exists purely for backward compatibility with older network protocols.

Signature

virtual void ServerMoveOld(float OldTimeStamp, FVector_NetQuantize10 OldAccel, uint8 OldMoveFlags)

Parameters

Name	Type	Description	Default
OldTimeStamp	float	Timestamp of the older move being resent.	—
OldAccel	FVector_NetQuantize10	Quantized acceleration for the old move.	—
OldMoveFlags	uint8	Compressed input flags for the old move (e.g. jump).	—

Return Type

void

Example

Legacy RPC declaration (engine-internal, deprecated path) C++

// Only relevant with SUPPORT_DEPRECATED_CHARACTER_MOVEMENT_RPCS=1 and p.NetUsePackedMovementRPCs=0:
CharacterOwner->ServerMoveOld(OldTimeStamp, OldAccel, OldMoveFlags);
