UCharacterMovementComponent::ServerMoveDual
Deprecated: ServerMoveDual() 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"

Description
Legacy server RPC that batches two consecutive client moves into a single call, used when a pending move couldn't be sent on its own tick and needs to piggyback on the next one.
Caveats & Gotchas
- • Deprecated since 4.26 alongside the rest of the non-packed RPC family; only compiled into an active path with SUPPORT_DEPRECATED_CHARACTER_MOVEMENT_RPCS=1 and p.NetUsePackedMovementRPCs=0.
- • The '0'-suffixed parameters (TimeStamp0, InAccel0, PendingFlags, View0) describe the earlier pending move; the unsuffixed parameters describe the current move — mixing them up silently corrupts replay ordering.
- • Chosen automatically by CallServerMove() when there's a queued PendingMove; game code should never call this directly.

| Name | Type | Description | Default |
|---|---|---|---|
| TimeStamp0 | float | Client timestamp for the first (pending) move. | — |

| PendingFlags | uint8 | Packed move flags for the first move. | — |
| 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. | — |
| ClientMovementMode | uint8 | Packed client movement mode after the second move. | — |
