SentientMobs v2.2.6

Teaching AI a Bit of Common Sense.

Before we begin, do consider joining our Discord server. It's where bug reports, feature suggestions, development updates, and the occasional sensible conversation tend to occur. Considerably more productive than arguing with the AI, as it happens. This release is all about stability, reliability, and resilience. No flashy new features, just a rather large number of improvements designed to make the AI considerably less likely to trip over itself.

Improvements

Core AI

* Improved overall null safety across multiple AI systems. * Added additional validation to prevent edge-case failures during behaviour updates. * Improved behaviour context validation and lifecycle management. * Enhanced herd behaviour updates after animals are attacked.

Herd AI

* Improved leader detection reliability. * Added validation for predicted target locations. * Improved safety checks for personalities, behaviour contexts, and attack cooldowns. * Integrated the required SquadManager dependency. * Minor code clean-up for improved code consistency.

Iron Golem AI

* Improved defend and punish behaviour validation. * Added additional target safety checks. * Fixed potential crashes related to strike tracking. * Added proper cleanup for temporary punish memories after behaviours finish.

Village AI

* Improved null safety within Villager Panic Behaviour. * Cached Iron Golem locations to prevent issues if the entity is removed during execution. * Reduced redundant location lookups. * Fixed an edge case affecting village escort behaviour around community chests.

Bug Fixes

* Fixed a cross-dimension AI issue where entities attempted to calculate distances between different worlds (e.g. Overworld <-> Nether), which could generate repeated IllegalArgumentExceptions and, under certain circumstances, affect server stability. * BaseBehavior.distanceTo() now validates world equality before performing distance calculations. * Cross-dimension distance checks now safely return Double.MAX_VALUE. * SmartSkeletonBehavior.findNearestTarget() now ignores entities located in different dimensions. * AI will now gracefully abandon targets that wander into another dimension instead of attempting the computational equivalent of measuring the distance to yesterday.

My Note

No shiny new features this time, just a great many AI behaviours learning not to panic, not to trip over null, and, perhaps most importantly, not to measure the distance between entirely different dimensions. Servers should now enjoy cleaner logs, fewer exceptions, and AI with considerably better judgement than before. Special thanks to Schasch for reporting the cross-dimension issue.

SentientMobs 2.2.5

Native Shopkeepers Support, Smarter AI Behaviors & Improved Stability ---

AI Behavior Improvements

* StateMachine now supports multiple behaviors within a single AIState, preventing behaviors from silently overwriting one another. * Fixed behavior coordination for combinations such as Golem Escort, Defend, Patrol, and other movement-related behaviors. * Villager stamina is now calculated from actual movement instead of behavior name detection. * Movement behaviors now update AI context only when pathfinding is actually executed.

Reload Reliability

* Reworked the plugin reload sequence. * Support systems are refreshed before loaded entities are re-registered. * Fixed an issue where AI could remain inactive after /reload until entities respawned or chunks were reloaded.

Native Shopkeepers Support

* Added native compatibility with the Shopkeepers plugin. * Shopkeepers NPCs are automatically ignored by SentientMobs AI. * Vanilla villagers continue to function normally. * Shopkeepers NPCs are also excluded from: * Labor Trades * Automatic Naming * Item Pickup Routing * Merchant Click Handling * Community Chest Proximity Logic * Added softdepend: Shopkeepers to plugin.yml. * New configuration option:

compatibility:
  shopkeepers:
    ignore-shopkeepers: true

Localization

* Improved LangManager error handling by using the plugin logger instead of printStackTrace(). --- Thank you for using SentientMobs!

SentientMobs 2.1.7

Language System & Trade Improvements

* Added a fully configurable language system * Added support for custom villager names through language files * Language files are now automatically generated inside the lang/ folder * Default language file: EN_lang.yml * Added /sm createlang <language> command to quickly generate new language templates * Added /sm setlang <language> command to instantly switch active language and save it to config * Villager names are now fully configurable from language files instead of being hardcoded * Fixed reversed Labor Trade pricing logic * Villagers now correctly trade multiple seeds for 1 Emerald instead of charging dozens of Emeralds for a single seed ---

How the Language System Works

The new language system allows server owners to fully customize plugin messages and villager names without editing the plugin itself.

Language File Structure

All language files are stored inside:

plugins/SentientMobs/lang/

Each language uses the format:

<LANGUAGE>_lang.yml

Examples:

EN_lang.yml
ID_lang.yml
JP_lang.yml

The plugin automatically creates EN_lang.yml on first startup as the default language template. ---

Active Language

The active language is controlled from config.yml. Example:

language: EN

Changing the language instantly changes: * Plugin messages * Villager names * AI-related text outputs * Future localized content ---

Villager Names

Villager names are now fully configurable directly from the language file. Example:

villager:
  names:
    male:
      - Eldrick
      - Yusuf

    female:
      - Minerva
      - Fatimah

    neutral:
      - Alex

New villagers will automatically use names from the currently active language file. ---

Commands

Create a new language template:

/sm createlang ID

This automatically generates:

ID_lang.yml

Switch active language instantly:

/sm setlang ID

The selected language is automatically saved to the configuration. ---

Villager Stamina Overhaul

* Completely redesigned Villager-exclusive stamina system * Added structured stamina states: * ENERGETIC * NORMAL * TIRED * EXHAUSTED

Villagers now lose stamina while:

* Working * Running from danger * Walking around the village

Villagers recover stamina by:

* Sleeping * Eating * Resting near village bells

Additional Improvements

* Dynamic movement speed adjustments based on stamina state * Sweat particles when exhausted * Sleep/rest particles while recovering * Villager AI behaviors are now deeply integrated with the new stamina manager * Added extensive stamina configuration options in config.yml * More immersive and realistic village simulation ---

Technical Changes

* Added dedicated VillagerStaminaManager * Refactored multiple villager AI behaviors to use the new stamina architecture * Improved internal language management system * Updated plugin version to 2.1.7 * Updated config version to 2.1.7 * Successfully compiled and verified with Maven build ---

Notes

This update heavily modernizes villager behavior systems and introduces full language customization support, making villages feel significantly more alive, configurable, and immersive.

Changes Included in This Update

Smarter Housing & Bed Navigation

* Villagers now target safe standing positions beside their assigned beds instead of pathing directly into the bed block * Fixed villagers circling around doors or staying outside houses when trying to go home * Improved indoor shelter detection so villagers prefer realistic indoor positions instead of random outdoor spots near beds * Fixed villagers sleeping outside by making them properly use their assigned bed at night

Improved Social Behavior

* Villagers can now share hunger and shelter information more naturally * Removed fake food item drops from social behavior * Food now comes directly from the village supply system instead

New Custom Villager Role: Supply Manager

Added a brand-new custom villager role: Supply Manager* * Supply Managers work near village community chests, not player chests * Supply Managers check for available food first, then check wheat if food is missing If wheat is available, Supply Managers craft bread by consuming exactly 3 wheat* from the village chest * Supply Managers deliver food directly to hungry villagers instead of allowing villagers to magically eat from storage

AI Movement Overhaul

- Vanilla-Like Fluidity: Eliminated "stiff" and "jittery" movement by removing manual velocity overrides. Mobs now move with natural Minecraft physics and smooth animations. - Natural Gravity: Fixed falling and jumping behavior. Mobs now fall at realistic speeds and jump over 1-block obstacles naturally during pursuit. - Smooth Rotation: Replaced teleport-based looking with reflection-based setRotation and native Paper lookAt. This prevents visual stuttering during combat maneuvers. - Pathfinder Integration: Pursuit logic now utilizes the server's native pathfinding (via setTarget), ensuring perfect obstacle avoidance and fluid navigation.

Tactical Coordination & Herd Defense

- Enhanced Herd Intelligence: Overhauled the Herd Defense system. When a mob is attacked, all same-type allies within a 20-block radius now join the defense simultaneously and reliably. - Illager Social Awareness: Illagers now share targets automatically. If one Illager engages a player, nearby allies will instantly coordinate a formation-based assault. - Optimized Performance: Replaced world-wide entity scanning with high-performance nearby entity checks, significantly reducing CPU usage during group coordination.

Cross-Platform Optimization (Spigot/Paper/Purpur)

- Platform-Aware Performance Tiers: Introduced dynamic AI update intervals. The plugin automatically tunes AI frequency based on the server platform to ensure maximum stability. - Dynamic Throttling: Added a safety system for Spigot/CraftBukkit that automatically throttles AI logic if server update times exceed 10ms, preventing main-thread lag. - Momentum Smoothing: Implemented momentum-based movement interpolation for non-Paper servers, mimicking Paper’s smooth pathing on Spigot and CraftBukkit. - Reflection Cache: Optimized all cross-platform API calls with a static reflection cache, eliminating the performance overhead of searching for server-specific methods.

Balancing & Refinement

- Villager Panic Tuning: Refined Villager panic speed and zig-zag maneuvers to feel more realistic and less erratic. Reduced panic speed effect to Speed I for better visual consistency. - Bug Fixes: Resolved various compilation errors and edge cases related to Location objects and target switching. _hafiydev | 16 May 2026_

This beta focuses heavily on major AI improvements, including smarter pathfinding, more adaptive combat behavior, improved target prediction, smoother movement logic, and better environmental awareness. Mobs now react faster, behave more naturally, and feel significantly less scripted during gameplay. Large portions of the AI engine were rewritten and optimized to create a more dynamic and immersive survival experience while improving overall server efficiency. This beta update also introduces official support for Spigot, CraftBukkit, and Purpur, expanding compatibility beyond Paper servers for the first time. Cross-platform systems have been redesigned to maintain stable and consistent AI behavior across multiple server implementations. Alongside compatibility improvements, many backend systems were cleaned up, several bugs were fixed, and various AI routines were refined in preparation for the full 2.0 release. As a beta build, some features may still be experimental and subject to further balancing and optimization.

Iron Golem: - Fixed Iron Golem not coming when villager is attacked/chased. - Improved pathfinding. Skeleton: - Fixed Skeletons not changing to melee mode. Zombie: - Fixed and Improved player/iron golem flanking feature for better coordination and communication. Code: - Fixed minor bugs and potential bugs. bStats: - Added statistics graphs from bStats.

Herd (cow, sheep, horse): - Added a group leader system when attacked, making attacking players more realistic. - Added "target prediction" system, now herd can predict where the player will run/attack. - Makes the herd's steps super smooth, not stiff when chasing. Spider: - Makes the spider's steps more efficient when chasing prey. - The spider will find various ways to reach the player and choose the fastest and most appropriate way. Iron Golem: - Fixed aggressive Iron golems (attacking players even though players are not attacking golems/villagers). Villager: - Villager will prioritize roads on dirt paths / grass paths, if not found, will look for the fastest path.

Zombie AI Enhancements

- Flanking System: Zombies coordinate to surround and flank players - Retreat Behavior: Zombies retreat when health is low and may call for help - Group Coordination: Improved group attack patterns with delayed strikes

Skeleton AI Enhancements
