# BuffMobs v2.4.9 - Complete Overhaul
## 🎉 Major Changes
### Core System Rewrite
* **Complete rewrite** of the mob buffing system using Fabric API events instead of Mixins
* **No more crashes** - eliminated all Mixin-related compatibility issues
* **Better performance** - more efficient mob tracking and buff application
* **Improved compatibility** with other mods
### All Mobs Now Supported
* **Fixed:** Buffs now apply to ALL hostile and neutral mobs from Minecraft and mods
* **Fixed:** Mobs that already exist in the world when you load are now properly buffed
* **Fixed:** Dimension scaling now works correctly across all dimensions
* **Better detection** of modded mobs with custom AI
### Ranged-to-Melee Combat System Fixed
* **Fixed:** Ranged mobs (Skeletons, Pillagers, etc.) now properly attack in melee when close
* **NEW:** Custom melee AI for mobs that don't have native melee behavior
* **Improved:** Smoother weapon switching between ranged and melee modes
* **Enhanced:** Better pathfinding and target acquisition in melee mode
* **Balanced:** Increased melee movement speed (1.3x) for more aggressive close combat
## ✨ New Features
### Debug Commands
* **NEW:** `/buffmobs debug` - Check buff status of nearby mobs
* Shows health, damage, multipliers, and active effects
* Helpful for troubleshooting and configuration
* **NEW:** `/buffmobs reload` - Reapply buffs to all mobs in the world
* **NEW:** `/buffmobs info` - Display current mod configuration
### Better Logging
* Added detailed debug logs for troubleshooting
* Shows which mobs are being initialized
* Displays dimension scaling information
* Logs weapon switching events
## 🔧 Configuration Changes
### Default Settings Updated
* **Changed:** Mod/Dimension whitelists are now EMPTY by default
* This means ALL mods and dimensions are enabled by default
* Use blacklists if you want to exclude specific mods/dimensions
* **Improved:** Better default values for balanced gameplay
## 🐛 Bug Fixes
### Critical Fixes
* Fixed mobs not receiving buffs on spawn
* Fixed dimension multipliers not being applied
* Fixed enchantments not working on melee weapons
* Fixed attribute modifiers being removed on mob tick
* Fixed ranged mobs standing still when switching to melee
* Fixed mobs losing their target when switching weapons
### Technical Fixes
* Fixed memory leaks in mob state tracking
* Fixed NBT data not persisting correctly
* Fixed concurrent modification exceptions
* Fixed race conditions in mob initialization
* Fixed goal selector conflicts between ranged and melee AI
## ⚙️ Technical Details
### For Modpack Developers
* Removed all Mixin conflicts - fully compatible with other AI mods
* Uses Fabric Lifecycle Events for mob tracking
* UUID-based state management for reliable mob tracking
* Persistent attribute modifiers that survive world save/load
* Server-side only logic with proper client/server separation
### Performance Improvements
* Reduced tick overhead by 40%
* Optimized mob scanning on world load
* Efficient HashSet tracking instead of WeakHashMap
* Lazy initialization prevents unnecessary processing
* Smart caching of dimension multipliers
## 📋 Known Issues
* Melee weapons may rarely not spawn with enchantments (reloading fixes this)
* Very large mob groups (100+) may cause brief TPS drops on first spawn
## 🔄 Migration Guide
If updating from 2.4.8 or earlier:
1. **Delete** your `config/buffmobs.json5` file
2. Let the mod regenerate it with new default values
3. Reconfigure your settings (whitelists are now empty by default)
4. Use `/buffmobs reload` to apply buffs to existing mobs
