This project may seem abandoned but I'm actually still working on it. I just am not really making any progress.

I got real time screen capture and input sending working pretty quickly but then it turned out that is not the hard part. I was planning to do a "pure" AI that would watch the screen to infer the gamestate but it's turning out that this is a very hard thing to do. I went down a computer vision rabbit hole for a while but there isn't really any good way to do this and I'd much rather spend my ... Read More →

It's not the greatest api, since you pass it a callback which it calls on one of it's own threads so communicating the data back to my main program required a threadsafe buffer.

Aissac is a first experiment in writing programs that can play video games. The program should watch the screen and submit user input the same way

problems and solutions as they come up.
I chose "The Binding of Isaac" as a first game because I ... Read More →
