UCharacterMovementComponent::SmoothCorrection
#include "GameFramework/CharacterMovementComponent.h"
Access: public
Specifiers: virtualoverride
Description
Reacts to a new transform received from a network update on the client, applying it and clearing bNetworkSmoothingComplete so future smoothing updates blend from the corrected state.
Caveats & Gotchas
- • Only runs on the client for simulated proxies / autonomous proxy corrections — it's part of the client-side prediction correction path, not something the server calls.
- • It is expected to actually apply the movement/transform update itself; simply overriding it and not moving the component (or not calling Super) will desync visuals from the corrected server state.
- • Sets bNetworkSmoothingComplete to false, which re-arms mesh smoothing interpolation over subsequent ticks — if you skip that, mesh location can visually snap instead of smoothly correcting.
