UCharacterMovementComponent::ClientAckGoodMove_Implementation

function Engine Since 4.26

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtualENGINE_API

Description

Called on the client when the server's move response indicates no correction was needed, so the acknowledged move can be removed from the pending SavedMoves list.

Caveats & Gotchas

• Dispatched from ClientHandleMoveResponse() rather than called directly — it's the 'no error' branch of the response handling.
• If the timestamp doesn't match any saved move (e.g. due to a prior reset), the acknowledgement is effectively a no-op for that move.
• Overriding this without calling the base implementation will leave stale moves in SavedMoves, which grows unbounded memory usage over time.
