AlaAggro

Every mob in the world becomes aggressive toward players the moment it spawns — passive farm animals (chickens, sheep, cows, pigs), aquatic creatures, ambient mobs, axolotls, and modded mobs. Vanilla hostile mobs (zombies, skeletons, etc.) are left alone — they are already hostile.

Features

• Universal aggression across the entire mob roster — even bats, fish, and axolotls.
• Boss guard — Wither, Ender Dragon and Elder Guardian are never touched (their custom AI phases would break).
• Datapack-friendly exclusion — add mobs to the entity tag alaaggro:excluded to opt them out without editing the config.
• Per-player exemption — /alaaggro exempt <player> temporarily removes a player from the aggro list.
• Reactive-only mode — flip a switch and mobs only attack after being hit first.
• Call for help — hurting one mob alerts neighbours of the same type within a configurable radius.
• Long-term memory — mobs do not forget the player when out of sight; resets on dimension change or long-distance teleport.
• Damage and speed multipliers with an absolute speed cap to keep fast mobs sane.
• Dimension blacklist — disable in The Nether, The End, or any modded dimension.
• Multi-language — English, Русский, 简体中文, Español, Português (Brasil), Deutsch, Français, العربية, हिन्दी, 日本語.
