UCharacterMovementComponent::OnRegister

function Engine Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtualoverride

Description

Called when the component is registered with its owning actor. Disables RVO avoidance on network clients and sets the network smoothing mode based on whether the world is playing a replay or running as a listen server.

Caveats & Gotchas

• If bUseRVOAvoidance is true and the component registers on a network client, avoidance is silently disabled since it's server-authoritative.
• Always call Super::OnRegister() first when overriding — the base implementation configures RVO and network smoothing before any custom setup runs.
• In WITH_EDITOR builds it also recomputes WalkableFloorZ from WalkableFloorAngle, so changing the angle only takes effect after (re)registration.

}
