UCharacterMovementComponent::ClientAckGoodMove

function Engine Deprecated Since 4.0

Deprecated: ClientAckGoodMove() is deprecated, use ClientHandleMoveResponse() 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 that tells the client no adjustment is needed for a given move, so it can be removed from SavedMoves.

Caveats & Gotchas

• Deprecated since UE 4.26 in favor of ClientHandleMoveResponse(), which handles both acknowledgement and correction through a single packed RPC.
• Only reachable when the deprecated legacy RPC path is active (SUPPORT_DEPRECATED_CHARACTER_MOVEMENT_RPCS=1 and p.NetUsePackedMovementRPCs=0).
• Distinct from ClientAckGoodMove_Implementation(), which is the modern packed-RPC handler still in active use — don't confuse the two.
