Villainous Fish AI
Augments the AI of minecraft fish so that they react to their environment more.
About this Mod
All this mod does is make vanilla fish attempt to swim away from projectiles, dropped items, and primed tnt.
The shorthand explanation
This mod is a joke about some of the advertising/behind the scenes of Call of Duty: Ghosts, where one of the points made about their new innovations is "Next generation Fish AI".
Their selling point was having fish swimming away from players (and maybe projectiles) to make them seem more dynamic and responsive. In practice, it works.. but isn't very reliable or breathtaking. Definitely overhyped.
So onto minecraft. In the base game, fish will already swim away from nearby players. This mod makes them attempt to swim away from dropped items, primed tnt, and projectiles as well.
