XanderCat

MegaBot based on my "Xander" robot framework with pluggable guns, radars, and drives. Currently using BasicRadar, StatDrive, and a CompoundGun which combines a StatGun, LinearGun and CircularGun.

Versions up through 2.1 are handcrafted without borrowing code or ideas from other robots. Version 3.0 uses a variation on the Wave Surfing drive from BasicGFSurfer, but a wave surfing drive of my own design is used in version 3.1. XanderCat could be made smaller by removing unused Xander components and taking advantage of some of the newer classes like Rules, but it's so far above the next smaller weight class that it doesn't really matter.

Current Version: 3.1

Best against: Any robot that spends too much time standing still, going straight, or going in circles.

Worst against: Unknown at this time.

Version 1.0

Based on a not-quite-complete Xander framework. Uses BasicRadar, OrbitalDrive, and a CompoundGun combining a CircularGun and a LinearGun.

Version 2.0

This version adds a StatGun to the CompoundGun (in order, the CompoundGun will consist of a StatGun, CircularGun, and LinearGun). The StatGun is a "Guess Factor" gun of my own design. I don't call it "Guess Factor" because, frankly, I hate that term. The stat gun supports variable configuration, with interchangable Segmenter modules. Version 2.0 uses a CompoundSegmenter, which combines a BulletTravelTimeSegmenter and a RelativeDirectionSegmenter. This segmenter combination categorizes the statistics based on approximate time it takes bullet to reach opponent and opponent heading relative to self.

Version 2.1

Version 2.1 adds better gun selection, tweaked parameters for firing, driving, and stat gun segmenting. For the driving, it drops the "inverse gravity bullet dodging", as it assumes opponents are using head-on or linear targeting, which likely causes worse performance against opponents using guess factor guns. Instead, it just randomizes movement a little more.

Version 3.0

This version drops the Orbital Drive, and instead uses a Wave Surfing drive based on the drive used by the BasicGFSurfer. This means I cannot credit myself entirely for this version, as I am using a modified version of a previously existing Wave Surfing drive. This version will serve as a reference point for my next version, which will use a Wave Surfing drive of my own design.

Version 3.1

Switched to using my StatDrive for driving, a form of wave surfing drive of my own design. This drive has not been tweaked yet, but seems to be doing it's job well so far. Will be interesting to see how it compares to version 3.0 in the rumble. This version also takes advantage of the ability to paint on the battlefield (very cool!), though it is disabled in the packaged form. It also benefits form a few minor tweaks to the Xander framework, for things like firing at enemies who are low on energy or disabled.

Version 3.2? (Possible Future Version)

This possible future version, if I have time to work on it, will focus on improving parameters based on analysis of combat results.

Other Versions

I may release various other minor versions that are just tweaks and bug fixes. There are a number of configurable parameters I could play with. At the same time, I don't want to pollute the rankings with a zillion versions of my robot. So...we'll see...
