That's great!
Never noticed that WhiteFang had BulletShielding before I tested it eventually using a traditional hot bot ;) Most successful shielders have virtual guns to simulate different targeting mechanisms, e.g. some are aiming one tick before fire, some are aiming in the right tick, both make shielding different. See that shielding more bots soon!
I will add some virtual guns after I work on automatic tuning. I have a weird behavior with my shielding algorithm. Normally a bot should be able to move 1 unit forward in a tick but when I set the maximum limit of moving to 1 it shields worser. Also, I see EnergyDome not moving more than 0.2 and ShieldBot not moving more than 0.1. Why move 0.1 while it is possible to move more and have a wider shielded arc?
