This custom packet will allow us to pass a position and rotation through the network connection. Two important things to remember: 1) register the packet with GNE using GNE::PacketParser::defaultRegisterPacket<PositionPacket>(); 2) Every custom packet needs a unique ID


  
  class PositionPacket : public GNE::Packet
  {
  public:
  
     PositionPacket( osg::Vec3 xyz, osg::Vec3 hpr, const std::string &ownerID );

default constructor PositionPacket();

copy constructor PositionPacket( const PositionPacket &p );


     virtual ~PositionPacket() {}
  
     static const int ID;
  
     virtual int getSize() const;
  
     virtual void writePacket( GNE::Buffer &raw ) const;
  
     virtual void readPacket( GNE::Buffer &raw );
  
     osg::Vec3 mXYZ;
     osg::Vec3 mHPR;
     std::string mOwnerID;
  };

This custom packet will allow us to pass a player's UniqueID upon exit to let server and other clients known a player has quit the game.


  
  class PlayerQuitPacket : public GNE::Packet
  {
  public:
  
     PlayerQuitPacket( const std::string& playerID );
     PlayerQuitPacket();
  
  public:
  
     PlayerQuitPacket( const PlayerQuitPacket& p );
  
     virtual ~PlayerQuitPacket() {}
  
     static const int ID;
  
     virtual int getSize() const;
  
     virtual void writePacket( GNE::Buffer& raw ) const;
  
     virtual void readPacket( GNE::Buffer& raw );
  
     std::string mPlayerID;
  };
  
  endif //PACKETS_INCLUDED
