Variables

Public

Name Type Remarks Include Path Unreal Specifiers
bDataAltered bool If this data was altered so that it doesn't correspond the produced source data (from merging, interpolating or extrapolating) Physics/NetworkPhysicsComponent.h  
bImportant bool If this data is marked as important (replicated reliably) Physics/NetworkPhysicsComponent.h  
bReceivedData bool If this data was received over the network or locally predicted. Physics/NetworkPhysicsComponent.h  
DeltaSourceData FNetworkPhysicsData * Pointer to a previous FNetworkPhysicsData which is valid during NetSerialize() to be used for delta serialization Physics/NetworkPhysicsComponent.h  
ImplementationComponent TStrongObjectPtr< UActorComponent > Thread safe pointer to the UActorComponent that implements the derived type of this data Note: This pointer can be accessed on both Game Thread and Physics Thread but you still need to ensure the read and write calls inside the UActorComponent are thread safe. Physics/NetworkPhysicsComponent.h  
LocalFrame int32 Local frame at which this data has been generated (not replicated, calculated from ServerFrame - FrameOffset ) Physics/NetworkPhysicsComponent.h  
ServerFrame int32 Server frame at which this data has been generated. Physics/NetworkPhysicsComponent.h  
UNetworkPhysicsComponent friend   Physics/NetworkPhysicsComponent.h  

Functions

Public

Name Remarks Include Path Unreal Specifiers

virtual void ApplyData ( UActorComponent* NetworkComponent
) const

 Apply the data onto the network physics component. Physics/NetworkPhysicsComponent.h  

virtual void BuildData ( const UActorComponent* NetworkComponent
)

 Build the data from the network physics component. Physics/NetworkPhysicsComponent.h  

void ClearDeltaSourceData()

   Physics/NetworkPhysicsComponent.h  

void ClearImplementationComponent()

   Physics/NetworkPhysicsComponent.h  

virtual bool CompareData ( const FNetworkPhysicsData& PredictedData
)

 Define how to compare client and server data for the same frame, returning false means the data differ enough to trigger a resimulation. Physics/NetworkPhysicsComponent.h  

virtual const FString DebugData()

 Return string with custom debug data Physics/NetworkPhysicsComponent.h  

virtual void DecayData ( float DecayAmount
)

 Use to decay desired data during resimulation if data is forward predicted. Physics/NetworkPhysicsComponent.h  

virtual void InterpolateData ( const FNetworkPhysicsData& MinData,
const FNetworkPhysicsData& MaxData
)

 Define how to interpolate between two data points if we have a gap between known data. Physics/NetworkPhysicsComponent.h  

virtual void MergeData ( const FNetworkPhysicsData& FromData
)

 Define how to merge data together Physics/NetworkPhysicsComponent.h  

void PrepareFrame ( int32 CurrentFrame,
bool bIsServer,
int32 ClientFrameOffset
)

   Physics/NetworkPhysicsComponent.h  

void SerializeFrames ( FArchive& Ar
)

 Serialize the data into/from the archive. Physics/NetworkPhysicsComponent.h  

void SetDeltaSourceData ( FNetworkPhysicsData* IntDeltaSourceData
)

   Physics/NetworkPhysicsComponent.h  

void SetImplementationComponent ( UActorComponent* InImplementationComponent
)

   Physics/NetworkPhysicsComponent.h  

void SetImportant ( bool bIsImportant
)

 Set if this data is important(replicated reliably) or unimportant(replicated unreliably) NOTE: Default is to handle all inputs as unimportant, while one time events can be marked as important. Physics/NetworkPhysicsComponent.h  

virtual void ValidateData ( const UActorComponent* NetworkComponent
)

 Validate data received on the server from clients EXAMPLE: Validate incoming inputs from clients and correct any invalid input commands. Physics/NetworkPhysicsComponent.h
