As a long time developer for macros & bot that uses AutoIt / Screencap & OCR.
Im just going to input some of my ideas here.
I dont play Ragnarok Online so bare with the idea.
1. Edit the RO File. (Im sure there is already existing file editor for RO)
1.1. Find the Monster-graphic file and turn it into green or something easily recognizable.
2. Create a macro that searches for "green" in your screen and loop it.
2.1. Once "green" has been found, move mouse, left click & use skill.
Information:
- The client has a protection against sendmessage, postmessage & vk_key codes.
- Since I dont play Ragnarok, I did tried to make an auto healer for a friend.
Info Here:
- You can use interceptor.dll to intercept your mouse movements / clicks to trick Ragnarok that human is using the mouse.
Info here:
Just HOPE that their in-house anti-cheat (the one the protects their client) does not block Pixel detection like Gameguard (INCA).
Good luck!
