Let me rephrase: there is no available "back-end" for the game through AHK. Meaning that AHK cannot communicate with the game except at the physical level.
The only way, which is incredibly inefficient, is to use AHK's FindClick() function and manually take pictures of every object in the game and then write mouse movements. Even if someone did this, AHK is not specifically designed for image recognition, real-time mouse movements, or really anything complex, so I doubt the script would even work.
There is a reason why you can minimize the 059 client and still have your character auto-aim at enemies. There would absolutely no way for AHK to so something like this; AHK simulates clicks, mouse movements, keyboard strokes, etc. that are on your screen.
You can use JPEXS to decompile the 059 client and just see how complex auto-aim is (I'm not a CS major). There is no way for AHK to do this.
