Looking forward to this.

I look forward to seeing your implementation. I tried making one at one time. It isn't a simple trick to get down. But I wonder if this could actually decrease your score against some robots that you already get 100% against. Like ones that have near head on targeting that never landed on your surfing, but might bypass your shield.

It can. But not by much more than a few percent, and your average score is still much better with it than without it. And I highly suspect that we'll soon see a generation of bots with bullet defenses intertwined with their movements much more than they currently are.

I actually feel a bit jealous about the current adding-bullet-shielding-to-megabots trend. A while ago I noticed GeomancyBS getting ~99% against Nene and other ridiculously high scores, and I wondered why other high-end bots weren't shielding. It was going to be my secret weapon, but now I guess I'll just have to find something else. :(

Well Nene also uses Raiko's gun, which was written back in 2004, long before bullet shielding or even surfing was a thing. It just has a strong movement. I had considered using BulletShielding for awhile to, at the time that GeomancyBS came out. But at the time I wasn't able to get it to work.

These days I might be able to, but I hadn't really given it much thought again before this latest round.

Sorry Sheldor. I guess I kind of let the cat out of the bag. I did briefly think about how nice it would be to get my score up closer to Diamond and DrussGT and then add bullet shielding in an attempt to briefly steal the top spot, but truth is, despite much effort, I have had very little success improving my wave surfing and guess factor targeting beyond where they are now.

I doubted that Skilgannon and Voidious would bother with trying to add bullet shielding, as they are more wave surfing and guess factor targeting purists who might not like the idea of adding an alternate behavior and/or risking losing a little score against non-vulnerable opponents, but I think the score boost for XanderCat was a little more than anyone was expecting and the temptation may be too much for them. :)

You're right on that it was something of a purity issue of me. It just felt like an ugly thing to implement. There is at least one other technique we already ignore, which is preloading data about specific opponents. But it's not "impure" in the same way and I could see myself adding Bullet Shielding augmentation to Diamond, but probably never preloading.
