Thanks! I have uncovered may of Doctor Bob's secrets. You can nearly 100% him if you watch energy drops and reverse direction at around 120 distance. Then just aim a little behind him.
I meant the secrets of how successful it is, not how to beat it. I am trying my hand at nanomelee, but I haven't had much success. (My robot TestMelee is a really crappy derivative of Infinity.) DoctorBob says it has NanoAndrew's movement, but it looks like there must be a little something more. I wondered if you had ever seen DB's code, or heard something from the author.
His code cannot be completely decompiled as he obfiscated it, but if you look around a bit, there are ways of figuring out what he did. Honestly, you can reverse engineer his good pretty easily by the fact that he cannot hit stop and go targets. His radar is lock onto nearest person and charge - which against weaker melee guns and movement works great. The bots that hide in the corner and make small movements counter him well though. Dustbunny does well because it runs from him (and everyone else) :)
