I know you can't really say anything from 1 battle, but I don't ever recall seeing a score vs Shadow like this one. =) Yay!

My Anti-Surfer gun tries to predict the enemy's surfing on the nearest wave, then restrict its min/max firing angles to those still reachable assuming the enemy surfed the nearest wave as expected. For figuring out what's reachable, I hacked up my precise MEA calculation with a different starting state. But basically I screwed that all up and it hardly worked at all. (About time I started writing unit tests...)

Despite being broken, I had tested this gun against all my worst matchups and it helped against Shadow. So hopefully it will work better now.

Ok, looks like 1.7.9 finally fixes "the" major bug(s) I introduced with the movement refactoring in 1.7.5. I guess I won't know for sure if it was one of the 1.7.8 changes unless I let it fill out its battles, but it started off tanking pretty hard and the wrong GFs in the flattener (fixed in 1.7.9) is exactly the type of thing I thought would be the problem. (I switched to precise intersection in the flattener, since it was free with the new wave processing, but copied a couple lines from the gun that also used precise MEA GFs.) I'm really happy to have the wave interpolation and bullet shadow fixes too, though, and wonder if they're the reason 1.7.9 is undefeated (that or luck).

Regardless, I'm happy I can move on to the rest of the movement refactor. There's still quite a lot to do. :-) It's amazing I can refactor or rewrite every 1-2 years, and every time, the previous code seems so terrible...

While the RoboRumble results don't bear much evidence, I'm quite happy with the progress I've made against top bots recently (while maintaining or increasing APS!). I mainly focus on Shadow and DrussGT, but also against a test bed that includes 6 other strong bots. I swapped out Scarlet for Tomcat because at least twice I saw a score of 85-90 (adaptive bullet power gone haywire?).

    abc.Shadow 3.83c
    darkcanuck.Pris 0.92
    davidalves.Phoenix 1.02
    jk.mega.DrussGT 2.2.0
    kc.serpent.WaveSerpent 2.11
    lxx.Tomcat 3.17.169
    mue.Ascendant 1.2.27
    voidious.Dookious 1.573cNDS (non-data saving)

Results over 100 seasons (plus an extra 200 of 1.6.12 vs Shadow / DrussGT):

Diamond	Shadow	Pris	Phoenix	DrussGT	WaveSerpent	Tomcat	Ascendant	Dookious	Avg	Seasons
v1.6.4	50.20	51.43	56.41	45.74	52.06	58.94	56.05	51.58	52.80	100
v1.6.12	52.46	60.74	61.13	49.30	57.45	58.66	62.81	58.60	57.64	150

There are very strange results for Tomcat's last version, but his aps against Druss and Diamond is about 50% now

Congrats! Did you test it or just looking at the Rumble? 2-3 battles isn't very accurate... But I should update DrussGT and Tomcat to latest versions in any case.

FYI:

• 100 battles vs Tomcat 3.27: 54.15
• 300 battles vs DrussGT 2.2.2: 49.00

Edit: Oops, Tomcat's at 3.29? Doh!

I lost 7-8 places with the latest version, so congratulations are not appropriate in this situation:) No i did not test, but now there're 9 battles and APS is still about 50%:) And yes, i did my previous post to encourage you to get last version of Tomcat:) Good luck with PM crown hunting:)

FYI, take 2 - 100 battles vs Tomcat 3.29: 52.89. Very nice work!

Thank you, but for me is better -5 APS vs Diamond, but + 1 APS overall:)

So far, this hurts vs Phoenix and Dookious and helps vs Shadow, but that's a trade-off I'm willing to make at the moment. It brings me from ~49 to ~51 vs Shadow. As usual, nothing helps vs DrussGT... There's plenty more I can do to tune this, and I could even end up with multiple Anti-Surfer guns in my VG, but I've made enough changes that I just want a sanity release before going much further.
