Ala Aggro

AlaAggro is now available on Fabric. Requires Fabric API.

Every mob in the world turns hostile the moment it spawns — cows, sheep, chickens,
fish, bats, axolotls, and modded mobs too. Vanilla monsters are left as they are;
they are already hostile.

Your pets are safe by default. Tamed wolves, cats, parrots and horses are left
alone. Baby animals and mobs wearing a name tag can be protected too — see
excludeBabies and excludeNamed in the config, or use /alaaggro set babies|named
in game.

What you get
- Universal aggression, including water and flying mobs.
- Bosses are never touched, and that includes bosses added by other mods.
- Mobs that hop or fly — slimes, ghasts, phantoms — keep their own behaviour
  instead of being broken.
- Tamed pets, baby animals and named mobs can each be protected separately.
- Call for help: hurt one mob and its neighbours of the same kind come for you.
- Long-term memory: a mob that was fighting you picks the fight back up instead
  of forgetting. It lets go when you change dimension or teleport far away.
- Damage and speed multipliers, with a cap so fast mobs stay playable and a floor
  so slow ones can still catch you.
- Per-player exemption with /alaaggro exempt, saved with your world.
- Reactive-only mode: mobs stay calm until something hits them first.
- Dimension blacklist, entity blacklist and whitelist, plus a datapack tag for
  modpack authors.
- Ten languages, and a settings screen you can edit without touching files.

Everything is configurable in config/alaaggro.json or live with /alaaggro.
