Functions

Access		Return	Name	Description
Public	virtual	void	Deinitialize()	Deinitializes the subsystem.
Protected		void	HandleOnReceivedUDPBytes(const TArray<uint8>& Bytes, const FString& IPAddress)	Helper function for processing DIS packets. Binds to OnReceivedBytes from the UDPSubsystem.
Public	virtual	void	Initialize(FSubsystemCollectionBase& Collection)	Initializes the subsystem.
Public		void	ProcessDISPacket(TArray<uint8> InData)	Processes a given DIS packet to determine the type of packet. Delegates handling of the packet to whatever is bound to the associated PDU type's OnPDUProcessed event.
