Member Data Documentation

bOpenAckedCalled

bool FSendingRepState::bOpenAckedCalled

Whether or not FRepLayout::OpenAcked has been called with this FRepState.

CDOCustomDeltaState

TArray<TSharedPtr<INetDeltaBaseState> > FSendingRepState::CDOCustomDeltaState

Same as RecentCustomDeltaState, but this will always remain as the initial CDO version. We use this to send all properties since channel was first opened (for bResendAllDataSinceOpen).

ChangeHistory

FRepChangedHistory FSendingRepState::ChangeHistory[MAX_CHANGE_HISTORY]

Circular buffer of changelists.

CheckpointCustomDeltaState

TArray<TSharedPtr<INetDeltaBaseState> > FSendingRepState::CheckpointCustomDeltaState

Same as RecentCustomDeltaState, but will represent the state at the last checkpoint.

CustomDeltaChangeIndex

uint32 FSendingRepState::CustomDeltaChangeIndex = 0

Tracking custom delta sends, for comparison against the changelist state.

HistoryEnd

int32 FSendingRepState::HistoryEnd

Index in the buffer where changelist history ends (i.e., the Newest changelist).

HistoryStart

int32 FSendingRepState::HistoryStart

Index in the buffer where changelist history starts (i.e., the Oldest changelist).

InactiveChangelist

TArray<uint16> FSendingRepState::InactiveChangelist

Properties which are inactive through conditions have their changes stored here, so they can be applied if/when the property becomes active.

This should always be a valid changelist, even if no properties are inactive.

InactiveParents

TBitArray FSendingRepState::InactiveParents

Cached set of inactive parent commands.

LastChangelistIndex

int32 FSendingRepState::LastChangelistIndex

The last change list history item we replicated from FRepChangelistState. (If we are caught up to FRepChangelistState::HistoryEnd, there are no new changelists to replicate).

LastCompareIndex

int32 FSendingRepState::LastCompareIndex

Tracks the last time this RepState actually replicated data. If this matches FRepChangelistState::CompareIndex, then there is definitely no new information since the last time we checked.

See also

FRepChangelistState::CompareIndex.

Note, we can't solely rely on on LastChangelistIndex, since changelists are stored in circular buffers.

LifetimeChangelist

TArray<uint16> FSendingRepState::LifetimeChangelist

The unique list of properties that have changed since the channel was first opened

MAX_CHANGE_HISTORY

constexpr int32 FSendingRepState::MAX_CHANGE_HISTORY = 32

staticconstexpr

The maximum number of individual changelists allowed.

NumNaks

int32 FSendingRepState::NumNaks

Number of Changelist history entries that have outstanding Naks.

PreOpenAckHistory

TArray<FRepChangedHistory> FSendingRepState::PreOpenAckHistory

List of changelists that were generated before the channel was fully opened.

RecentCustomDeltaState

TArray<TSharedPtr<INetDeltaBaseState> > FSendingRepState::RecentCustomDeltaState

This is the delta state we need to compare with when determining what to send to a client for custom delta properties.

RepChangedPropertyTracker

TSharedPtr<FRepChangedPropertyTracker> FSendingRepState::RepChangedPropertyTracker

RepFlags

FReplicationFlags FSendingRepState::RepFlags

Retirement

TArray<FPropertyRetirement> FSendingRepState::Retirement

Array of property retirements that we'll use to track retransmission for Custom Delta Properties.

SavedRemoteRole

TEnumAsByte<ENetRole> FSendingRepState::SavedRemoteRole = ROLE_MAX

SavedRole

TEnumAsByte<ENetRole> FSendingRepState::SavedRole = ROLE_MAX
