Are there bots like MoxieBot, which instead of intercepting HoT bullets, deliberately create a shadow to which they move on?
MoxieBot is quite cool, but unfortunately does not run reliably in the modern robocode engine. I think we still have a lot to learn from this bot.
I myself clearly have buggy bullet safety shadow code since I see enemy bullet in the calculated shadow zone quite often.
I think with a modern Passive Bullet Shadower, you can easily implement Active Bullet Shadower by brute-forcing firing angles — and actually with some math you should be able to calculate that directly.
I've been long thinking about some smooth transition between Bullet Shielder to Active Bullet Shadower and Passive Bullet Shadower. E.g., shield at first, then begin dodging. When there's a chance to shadow, do that deliberately if worth the miss.
