Transform Every Mob Into A Genuine Threat With Surgical Precision

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The Problem With Predictable Mobs
Minecraft survival is only dangerous for the first few nights. After that, players know exactly which mobs to fear and which to ignore. Cows, chickens, sheep - they're background noise. Free food. Zero threat.
Your hardcore survival server, RPG progression system, or custom difficulty mechanics all lose impact because half the mobs in your world are harmless by design. Players walk through forests full of animals without concern.
Other mob aggression plugins exist, but they're either abandoned (no 1.21 support), poorly optimized (memory leaks, ghost targets), or lack granular control (all-or-nothing aggression).
The Precision Threat Management System
MoreAgressiveAnimals is a precision mob behavior plugin built for Paper 1.21.4+ with modern architecture and deep per-mob customization. Every mob type gets independent configuration. Every attack parameter is controllable. Every edge case is handled.
This isn't "make all animals attack". This is surgical control over mob behavior that lets you create exactly the difficulty curve you want.

Features That Rebuild Mob Behavior
Per-Mob Configuration Independence
60+ mob types with individual settings profiles:
Want aggressive cows but passive chickens? Done. Wolves that hunt in packs but foxes that flee? Configured in 5 lines.
Business value: Precision difficulty design. You don't compromise on vision.
Dual Aggression Mode System
Two fundamentally different AI behaviors:
Per-mob configuration. Cows can be always-aggressive while pigs are retaliation-only.
Business value: Creates varied threat levels. Players can't predict behavior from appearance.
Target Selection Strategies
Always-aggressive mobs choose targets intelligently:
Configurable per mob type. Wolves use "lowest-health" to finish off weak players. Cows use "random" for chaos.
Business value: Strategic depth. Players can't game the AI by standing back.
Group Aggression System
When one mob is attacked, nearby mobs of the same type join the fight:
Players can't pick off animals one by one safely. Hitting one cow in a herd aggros the entire herd within 20 blocks.
Business value: Punishes careless combat. Forces tactical thinking.
Attack Cooldown After Stop
Configurable delay before mob can re-acquire new target:
Business value: Reduces frustration of "mob instantly locks onto new player" scenarios.
Advanced Health Thresholds
Two-tier health management:
Mobs don't fight to the death mindlessly. They retreat when wounded. They stop before killing player (configurable mercy).
Business value: Balanced difficulty. Challenging without being unfair.
Acquisition & Deacquisition Ranges
Independent detection and pursuit distances:
Create persistent hunters (acquisition 10, deacquisition 50) or cautious attackers (acquisition 20, deacquisition 15).
Business value: Controls chase length. Long pursuits create tension, short ones create safety zones.
Speed & Leap Control
Physical behavior modification:
Chickens with 1.25x speed and 0.3 leap height become bouncing threats. Wolves with 1.5x speed chase down sprinting players.
Business value: Visual variety. Not all aggression looks the same.
Player State Targeting
Control when mobs can attack based on player state:
Create mobs that only attack sprinting players. Or mobs that ignore sneaking players (stealth mechanic).
Business value: Encourages strategic movement. Players adapt behavior to mob rules.
Team Protection System
Scoreboard team integration:
Business value: Protects team gameplay. Mobs don't break faction systems.
NPC Plugin Compatibility
Native integration with:
Plugin automatically excludes these from aggression system. No conflicts with other plugins' custom entities.
Business value: Works alongside your existing custom mob systems.
World & Difficulty Filtering
Spatial and condition-based control:
Business value: Different danger levels per world. Safe spawn world, deadly resource worlds.
Aquatic Mob Intelligence
Water-based mob targeting:
Business value: Realistic behavior. Water mobs stay threatening in water, harmless on land.
Visual Scaling System
MC 1.20.5+ feature - mobs grow when aggressive:
Business value: Instant visual feedback. Players see when mob is dangerous.
Administrative Control Commands
Full debugging and management suite:
Business value: Test configurations live. Debug issues without server restart.
