How much experience do I need to make a bot and program in unity?

I meant like the bot clicks on two locations on the screen. Is that what that code does?

...Ofcourse i'm learning to program all I asked was how long it would take for me to start experimenting with botting. I don't know what Sendkeys means but i'm guessing it just double clicks. I'm asking how long it would take for me to learn how to make a botting program that ex. clicks on my username then on my recent started threads. How does that even work? Do you need to use pixels to tell it where to click? Or do you use cheat engine for whatever reason?

There is more than learning the language syntax and features. Now you need to learn about Windows(R), and how to get the info you need / manipulate things. For example, you could make a pixel bot, or a ReadProcessMemory bot or even injected. To click on a specific text is hard because that generally required "word / letter recognition which isn't 100% straight forward..it's complicated depending on font etc. There is more than 1 way to do most tasks: you have to choose which is the best for your project.

If you knew which tutorials to read, maybe 2-3 months before you understand windows well enough / what you actually want to do (as far as read from a process, a file, what is a process, codecaves, etc etc). All depends how much/what you read. Also depends what you mean by "bot" ... auto-clickers can be considered bots, which is relatively simple: All depends. Big projects may use several methods (pixel + mem read + read log files, etc)
-As for Unity, idk, sorry.
