Introduction
MegaBot based on my "Xander" robot framework with pluggable guns, radars, and drives. XanderCat is the flagship of my robot fleet. It is a multi-mode robot using multiple guns and drives, but it's main drive is a Go-To/True hybrid wave surfing drive I call the Evolution Drive, and it's main gun is a guess factor gun.
Versions up through 2.1 and from 3.1 onward are handcrafted without borrowing code 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 and beyond. 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.
Best against: Any robot that spends too much time standing still, going straight, going in circles, or doing basic mirroring.
Worst against: Nothing specific, but still need to improve against the middle pack.

Version Ranks
Note: Best Change and Worst Change are the change from previous version against the given opponent.
Note: Starting from version 6.4 onward in the table, I am ignoring nat.BlackHole 2.0gamma and nat.Samekh 0.4, as scores against them always fluctuate rather wildly.

Series 1.x
This series of robots was released while work on the Xander framework was still ongoing. Targeting and drive strategies were somewhat simple. No surfing or guess-factor targeting.
Series 2.x
This series introduced my earlist concept on guess factor targeting. Drive strategy was still simple.
Series 3.x
This series introduced wave surfing, and improvements to the guess factor gun. Version 3.0 used a modified version of the BasicGTSurfer wave surfing drive as a reference point, with all later versions in the line using a wave surfing drive of my own design. Towards the end of this line, I introduced virtual hit ratios, where all guns would provide aiming information for every shot to determine whether or not their aims would have hit the target or not.
Series 4.x
This series focused largely on drive improvements, including improvements to the wave surfing drive, dive protection, and a new Ram Escape drive. This series also improved how fire power is selected.
Series 5.x
This series focuses on using a new strategy for calculating factors in guess factor guns and wave surfing drives, surfing multiple waves simultaneously, paying more attention to robot width, improving wall avoidance, and improving segmentation selection and processing.
Series 6.x
XanderCat series 6 focuses on taking everything learned so far and evolving it into a new set of components, or at the very least, cleaning up old components or features that did not work out. Series 6 introduces the new Evolution Drive, an updated Wave Surfing drive, and new ways of handling factor arrays.
Series 7.x
XanderCat series 7 uses the first release-ready version of the Xander framework. With the knowledge gained over prior versions of XanderCat, the Xander framework has undergone a final refactoring and cleanup and is now considered ready for public use. The Xander framework can be considered as version 1.0. In addition to using the finished Xander framework, series 7 may see updates to the main drive and gun, as well as a first release into the melee competition.
Version 7.0
This version is mostly about using the refactored and cleaned up version of the Xander framework. There should not be much change in the Rumble rank with this version. If the rank drops significantly, it means some bugs slipped through and I will need to embark on a new round of debugging.
Changes from previous version:
- Xander framework refactoring and cleanup. XanderCat now uses the Xander framework version 1.0.
- Drive tree changed to use separate branches for head-on and linear targeting detection rather than having that functionality jammed into the main Evolution Drive.
- Number of Gun bins for the factor array based guns reduced from 121 to 91 (I don't think this will degrade performance, but it should help reduce turn time)
- Further increased bullet shielding detection threshold, as it was still occasionally getting false positives.
Version 7.0.1
- Linear and Head-On Avoidance Drives were accidentally set up without distancing. Applied same distancing to these drives as is used on the main drive.
- Fixed issue where NullPointerException could occur in the Linear Avoidance Drive.
- Fixed issue in Mirror Detector that was causing mirror detection to be inconsistent.
Version 7.0.2
- Reverted back to using targeting detectors within the main Evolution Drive.
- Adjusted various drive and gun selectors.
- Fixed bug where head-on gun wasn't getting used for disabled opponents.
Version 7.0.3
- Fixed bug where disabled robot gun was not getting properly initialized, resulting in NullPointerExceptions.
- Minor change to early-game factor array initialization to be more consistent with version 6.8 and 6.9.
Version 7.0.4
- Fix recurring exception due to how guns were set up in previous version. Not expecting this to change performance though.
- No longer using rolling history on main gun. There wasn't much value to it and code will run faster without it.
