Thank god your feeling better man. Just focus on recovery right now.
When your all better I would appreciate it if you would notify me please and thank you.
The thing I want to point out is, how effective would a pixel based Aim bot be?
You mention variability, so you could account for tolerance levels. But over all, depending on resolution as well, it can be VERY memory expensive and therefore unpractical.
Now, if you were to change all the enemy models to say... red boxes, and pixel search / aim based on that, it may prove more fruitful.
I'm back and working on it again!
