UCharacterMovementComponent::ServerMoveDual_Validate
Deprecated: Part of the deprecated legacy ServerMoveDual RPC pair; use the packed movement RPC path instead.
#include "GameFramework/CharacterMovementComponent.h"
Access: public
Specifiers: virtual
Description
Server-side RPC validation for the legacy ServerMoveDual — returning false rejects both packed moves and can flag the connection as sending invalid data.
Caveats & Gotchas
- • Generated as the WithValidation half of a UFUNCTION(Server) pair for ServerMoveDual; only relevant on the legacy (non-packed) RPC path.
- • A false return discards both the pending and current move together, not just the offending one.
- • Only reached when legacy movement RPCs are active (SUPPORT_DEPRECATED_CHARACTER_MOVEMENT_RPCS=1, p.NetUsePackedMovementRPCs=0).

| View0 | uint32 | Compressed client view for the first move. | — |
| TimeStamp | float | Client timestamp for the second move. | — |
| InAccel | FVector_NetQuantize10 | Compressed acceleration for the second move. | — |
| ClientLoc | FVector_NetQuantize100 | Client's resultant location after the second move. | — |
| NewFlags | uint8 | Packed move flags for the second move. | — |
| ClientRoll | uint8 | Compressed client view roll for the second move. | — |
| View | uint32 | Compressed client view yaw/pitch for the second move. | — |
| ClientMovementBase | UPrimitiveComponent* | Component the client believes it's standing on after the second move. | — |
| ClientBaseBoneName | FName | Bone name on the client's movement base, if a skeletal mesh. | — |
