UCharacterMovementComponent::HasPredictionData_Server

function Engine Since 4.0

#include "GameFramework/CharacterMovementComponent.h"

Access: public Specifiers: virtualoverride

Description

Returns true if server-side movement prediction data has already been allocated for this component.

Caveats & Gotchas

• Checking this before calling GetPredictionData_Server_Character() lets you avoid triggering the lazy allocation when you only want to know whether prediction has been set up yet.
• Returns false on clients, since server prediction data is never allocated there under normal conditions.
• SendClientAdjustment() itself guards on this — if it's false, there's no bForceClientUpdate flag or last-acknowledged-move data to check, so no correction can be sent.

Example

Guarding server-only correction logic C++

UCharacterMovementComponent* MoveComp = GetCharacterMovement();
if (HasAuthority() && MoveComp->HasPredictionData_Server())
{
	FNetworkPredictionData_Server_Character* ServerData = MoveComp->GetPredictionData_Server_Character();
	// Safe to inspect ServerData here.
}
