WorldPacket packet; packet << "Hello, world!"; packet.rfinish();
WorldPacket packet; packet << uint16_t(42) << float(3.14) << "Foo" << uint8_t(1); packet.rfinish();This example creates a new WorldPacket object and adds several different types of data to the packet, including an unsigned 16-bit integer, a float, a string, and an unsigned 8-bit integer. The rfinish method is then called to indicate that the packet is complete and ready to be sent. It is difficult to determine the package library being used with just the rfinish method as it is a common method name used by many different libraries. However, based on the use of the WorldPacket class, it is likely that the packet library being used is either Boost.Asio or RakNet.
