Need some help creating a bot

[vipamine33]

Hello ,
So to get into hacking a making bots i learned the basics of C++ and now as a project i am gonna creat a simple bot (for a mmorpg game) that press 'F' each time the color of the bait changes (when it goes underwater) also i am creating this to learn and maybe for personal use and i will create also a memory type bot but right now i am intersted in learning how does the screen scraper bots work
someone already created a bot like this i can send link in PM so you can check it
Also i just need you to put me on the right track as i found many guides for AutoIT bots or AHK and memory type bots but didnt find any for screen scrapper (only few auto-aim bots and they are not the same as my case here and they got me confused)
well ty alot for reading and i hope someone helps me
