ACharacter::ServerMoveDualNoBase
Deprecated: Use ServerMovePacked instead.

Specifiers: UFUNCTIONunreliableserverWithValidation
Description
Dual-move variant of ServerMoveNoBase, batching two consecutive client moves into a single RPC when neither involves a movement base. Reduces per-move RPC overhead by half when the character is airborne or on flat ground.
Caveats & Gotchas
- • Deprecated in favour of ServerMovePacked. The packed path handles dual-move batching internally and is the preferred approach in UE5+.
- • Only the final client location (ClientLoc) is sent for the second move — the intermediate location after the first move is inferred server-side, so any discontinuity between moves may be invisible to the server until the next correction.
- • Both moves share the same null base context; if the character lands on a moving base mid-dual-move, the base will not be transmitted until the next ServerMove call.

Return Type
void Example
Internally dispatched by CharacterMovementComponent C++
// Not called directly. CharacterMovementComponent selects
// ServerMoveDualNoBase when:
// - Two pending moves exist with no base
// - The packed RPC path is disabled
// To intercept, override ServerMoveDualNoBase_Implementation.See Also
