Member Function Documentation

◆ GetBaseServerMoveDeltaTime()

float FNetworkPredictionData_Server_Character::GetBaseServerMoveDeltaTime	(	float	ClientTimeStamp,
		float	ActorTimeDilation
	)		const

Returns base time delta to use for a ServerMove, default calculation (no time discrepancy resolution)

◆ GetServerMoveDeltaTime()

float FNetworkPredictionData_Server_Character::GetServerMoveDeltaTime	(	float	ClientTimeStamp,
		float	ActorTimeDilation
	)		const

Returns time delta to use for the current ServerMove(). Takes into account time discrepancy resolution if active.

◆ Serialize()

void FNetworkPredictionData_Server_Character::Serialize ( FArchive & Archive )

virtual

Reimplemented from FNetworkPredictionData_Server.

Member Data Documentation

◆ bForceClientUpdate

uint32 FNetworkPredictionData_Server_Character::bForceClientUpdate

Force client update on the next ServerMoveHandleClientError() call.

◆ bResolvingTimeDiscrepancy

bool FNetworkPredictionData_Server_Character::bResolvingTimeDiscrepancy

True if currently in the process of resolving time discrepancy

◆ CurrentClientTimeStamp

float FNetworkPredictionData_Server_Character::CurrentClientTimeStamp

Timestamp from the client of most recent ServerMove() processed for this player. Reset occasionally for timestamp resets (to maintain accuracy).

◆ LastReceivedClientTimeStamp

float FNetworkPredictionData_Server_Character::LastReceivedClientTimeStamp

Timestamp from the client of most recent ServerMove() received for this player, including rejected requests.

◆ LastUpdateTime

float FNetworkPredictionData_Server_Character::LastUpdateTime

Last time server updated client with a move correction

◆ LifetimeRawTimeDiscrepancy

float FNetworkPredictionData_Server_Character::LifetimeRawTimeDiscrepancy

Accumulated timestamp difference between autonomous client and server for tracking long-term trends

◆ MaxMoveDeltaTime

float FNetworkPredictionData_Server_Character::MaxMoveDeltaTime

Max delta time for a given move, in real seconds Based off of AGameNetworkManager::MaxMoveDeltaTime config setting, but can be modified per actor if needed. Note: This was previously named MaxResponseTime, but has been renamed to reflect what it does more accurately

◆ PendingAdjustment

FClientAdjustment FNetworkPredictionData_Server_Character::PendingAdjustment

◆ ServerAccumulatedClientTimeStamp

double FNetworkPredictionData_Server_Character::ServerAccumulatedClientTimeStamp

Timestamp of total elapsed client time. Similar to CurrentClientTimestamp but this is accumulated with the calculated DeltaTime for each move on the server.

◆ ServerTimeStampLastServerMove

float FNetworkPredictionData_Server_Character::ServerTimeStampLastServerMove

Server clock time when last server move was received from client (does NOT include forced moves on server)

◆ TimeDiscrepancy

float FNetworkPredictionData_Server_Character::TimeDiscrepancy

Current time discrepancy between client-reported moves and time passed on the server. Time discrepancy resolution's goal is to keep this near zero.

◆ TimeDiscrepancyAccumulatedClientDeltasSinceLastServerTick

float FNetworkPredictionData_Server_Character::TimeDiscrepancyAccumulatedClientDeltasSinceLastServerTick

When bResolvingTimeDiscrepancy is true, we are in time discrepancy resolution mode where we bound move deltas by Server Deltas. In cases where there are multiple ServerMove RPCs handled within one server frame tick, we need to accumulate the client deltas of the "no tick" Moves so that the next Move processed that the server server has ticked for takes into account those previous deltas. If we did not use this, the higher the framerate of a client vs the server results in more punishment/payback time.

◆ TimeDiscrepancyResolutionMoveDeltaOverride

float FNetworkPredictionData_Server_Character::TimeDiscrepancyResolutionMoveDeltaOverride

When bResolvingTimeDiscrepancy is true, we are in time discrepancy resolution mode whose output is this value (to be used as the DeltaTime for current ServerMove)

◆ WorldCreationTime

float FNetworkPredictionData_Server_Character::WorldCreationTime

Creation time of this prediction data, used to contextualize LifetimeRawTimeDiscrepancy
