Always Hostile Animals
Always Hostile Animals makes normally passive, neutral mobs such as cows, pigs, sheep and chickens attack players they can see, so survival worlds lose their safe livestock.
What it does
Creatures that are passive or neutral by default become aggressive toward players in sight. Livestock such as cows and goats, along with horses, llamas, rabbits and parrots, are among the vanilla animals affected, and modded creatures that use the CREATURE, AMBIENT or WATER categories can be targeted as well. Attack goals are added to each mob's existing AI at runtime, so the original behavior of the mob is kept.
The mod sets an attack damage attribute on non-monster mobs that lack one, and it leaves hostile monsters such as zombies and skeletons unchanged. Miscellaneous entities like boats, minecarts, projectiles and items are not affected. The mod is built for NeoForge and runs only on the server, so players join without installing it, and it works on dedicated servers. A toggle to disable the effect is planned, and aquatic AI and fish behavior are listed as later work.

Attack goals are added to each mob's AI without replacing the goals it already has.
Attack damage attribute
Non-monster mobs that lack a generic attack damage attribute receive one, so they can deal damage.

How it compares
Passive Mobs is server-side only, open source under the MIT License and published for NeoForge 1.21.10, so it targets the same mob type on a narrower version. Center of the World needs the server and is licensed as All rights reserved, with NeoForge files for 1.21.8 – 1.21.10. Always Hostile Animals is also server-side only, and is not open source.
