AngryCow 🐄
A Paper plugin that makes cows aggressive with an invasion mode to turn your server into bovine chaos at will.

Features
- Aggressive cows: spot and attack players within a configurable radius; health, damage, speed, and melee reach fully adjustable.
- Invasion mode (
/angrycow invasion start): spawns cows in successive waves around each player, with an extended attack radius for the entire duration of the event. - Fine targeting: allowed/excluded worlds via whitelist or blacklist, immune game modes (creative/spectator by default).
- 100% config-driven: radii, stats, worlds, message texts (with colors and placeholders) — nothing is hardcoded.
- Granular permissions:
angrycow.reloadandangrycow.invasionare independent, grouped underangrycow.*. - Designed for performance: path recalculation is throttled (configurable), important when an invasion makes dozens of cows run at the same time.
Compatibility
Paper / Purpur 1.21 → 26.2. Relies entirely on stable public APIs (Mob Goal API, Entity Pathfinder API, MAX_HEALTH / MOVEMENT_SPEED attributes); none of the 26.2 API breakages ("Chaos Cubed": Adventure 5 migration, BookMeta, AbstractCubeMob hierarchy) are used.
Installation
- Get the
.jar(download it on Modrinth). - Drop it into the
plugins/folder of your Paper or Purpur server. - Restart the server — a default
config.ymlis generated inplugins/AngryCow/.
Configuration
Everything is set in config.yml, nothing is hardcoded in the code.
