Ragnarok Online Clientless Bot

A lightweight, clientless bot for Ragnarok Online written in C++.
This project demonstrates how to connect to a RO server using raw packets:
Login Server → Character Server → Map Server, without using the official game client.

---

🚀 Features

• Connects to RO login server and authenticates using username/password
• Retrieves and selects a character from the character server
• Connects to the map server and sends initial handshake packets
• Designed to be expandable into a full clientless bot
• Structured with modular code for login, character, and map logic

⚙️ Configuration

Edit the config.h file to match your RO server:

#define RO_SERVER_IP     "127.0.0.1"
#define RO_LOGIN_PORT    6900
#define RO_USERNAME      "your_username"
#define RO_PASSWORD      "your_password"
#define RO_SELECTED_CHAR_INDEX 0
#define RO_PACKET_VER    20220404 // Use the version your server expects

🛠️ Build Instructions (Windows)

1. Requirements

   • Visual Studio or any C++ compiler supporting C++11+
   • Winsock2 (usually included with Windows SDK)

2. Build Steps

   • Open project folder in Visual Studio
   • Include all .cpp and .h files in your project
   • Build and run main.cpp

3. CLI (Optional)

If you're using a CLI or Makefile setup:

cl /EHsc /Fe:ro_bot.exe main.cpp network\login.cpp network\char.cpp network\map.cpp /I. /Ishared /link ws2_32.lib

📌 Notes

• This is a learning tool and not meant for abuse.
• It assumes the RO server uses the standard packet flow (0x0064, 0x0065, 0x0066, 0x0072, etc.).
• You can expand this bot by parsing map packets, moving the character, attacking, etc.

🧠 TODO / Ideas

• Packet parser & sniffer integration
• Movement and command system
• Auto-login/character reconnect
