Description
Always Hostile Animals
All passive and neutral mobs become instantly hostile!
This mod turns cows, pigs, sheep, chickens, horses, goats, llamas, rabbits, parrots and many more (including modded creatures) into aggressive attackers that target players on sight.
Perfect for chaos survival challenges, hardcore playthroughs, or servers where nothing is safe anymore.
⚠️ Note: Aquatic mobs (fish, turtles, etc.) do not attack yet. This will be added in a future update.
🧩 Features
- 🔥 Instant aggression: Passive and neutral creatures immediately attack players.
- 🧠 Injected AI goals: Attack and target goals are added dynamically without breaking existing mob AI.
- 💥 Automatic attributes: Ensures that every non-monster mob has the
generic.attack_damageattribute. - 🌐 Mod compatible: Works with modded mobs that use proper categories (
CREATURE,AMBIENT,WATER_*). - 🧱 Server-ready: Fully functional on dedicated servers.
❌ Not affected
- Hostile mobs (zombies, skeletons, etc.) — unchanged
MISCentities (boats, minecarts, projectiles, items)- Aquatic mobs (support planned)
⚙️ Compatibility
- Minecraft: 1.21.1
- Loader: NeoForge (21.1.x)
- No known incompatibilities
- Works in most modpacks unless another mod fully overrides AI goals
📦 Installation
Install NeoForge 1.21.1
Place the JAR into your
mods/folderLaunch the game or server
For consistent behavior, use a new world, so newly spawned entities get the hostile AI injected correctly.
📄 Technical Details
- Registers the
generic.attack_damageattribute for all non-monster mobs usingEntityAttributeModificationEvent - Adds attack and target goals during
EntityJoinLevelEvent - Safety checks prevent duplicate goals or crash conditions
- A damage fallback ensures that mobs without an attribute still deal correct melee damage
⚡ Performance
- 100% event-driven (no tick-loop scanning)
- Lightweight and safe for large modpacks
- No noticeable performance impact
💬 FAQ
Q: Does it work with modded animals?
A: Yes — any entity using CREATURE, AMBIENT, or WATER_* categories is supported.
(Full aquatic AI coming in a later version.)
Q: Do baby animals also attack?
A: Yes. A toggle to disable this is planned.
Q: Why don’t fish attack yet?
A: Aquatic pathfinding behaves differently; this feature is planned for v1.1+.
🗺️ Roadmap
- v1.5: Aquatic mob attack AI
- v2.0: Config options (damage scaling, whitelists/blacklists)
- later: Datapack/tag support
