#include "WorldPacket.h" WorldPacket packet; packet << uint32(1234) << uint8(1) << "hello"; std::string hexlike = packet.Hexlike();The above code creates a WorldPacket object, adds three different data types to it, and then converts it to hexlike format using the `Hexlike()` method of the WorldPacket class. The resulting `hexlike` string will look something like this: `"0D 12 02 00 00 00 00 00 01 68 65 6C 6C 6F"`. One of the common libraries that handles WorldPacket in C++ is the TrinityCore project, which is a server emulator for World of Warcraft. The TrinityCore project provides a robust set of C++ classes and functions for handling WorldPacket, such as the `WorldPacket` class used in the example above.
