🎮 BuffMobs v2.5.4 - Changelog

🔧 Bug Fixes

Critical Crash Fix

Fixed game-breaking crash when ranged mobs attempted to switch to melee mode
Resolved NoSuchFieldException: goalSelector error that occurred during mob initialization
Improved reflection-based AI goal management for better compatibility with Minecraft 1.21.10

Ranged mobs (skeletons, piglins, pillagers) now reliably switch between ranged and melee weapons
Improved goal selector initialization with better error handling
Added safety checks to prevent crashes when reflection fails

Performance

Optimized reflection initialization (runs once at startup)
Reduced overhead in mob behavior updates
Better cleanup of mob states when entities are unloaded

✅ What Still Works

All existing features remain fully functional:

✨ Progressive mob scaling based on world days
⚔️ Dynamic weapon switching for ranged mobs

BuffMobs v2.5.3 - Hotfix🔧 Major Fixes

Configuration System Completely Rebuilt

The configuration system has been completely rewritten to fix persistent issues with settings not saving properly.

What was fixed:

✅ Configuration values now persist correctly - Your settings will no longer reset when you change them
✅ Dimension Scaling saves correctly - Setting up dimension-specific multipliers now persists properly
✅ All filter lists work as expected - Blacklists and whitelists for mobs, mods, and dimensions now save correctly

Blacklist/Whitelist System Fixed

The mob filtering system has been completely overhauled:

✅ Blacklists now work correctly - Mobs in the blacklist will no longer receive buffs
✅ /buffmobs reload now removes buffs - When you reload, mobs that are now blacklisted will have their buffs removed
✅ Supports both ID formats - Works with both modern (minecraft:zombie) and legacy (EntityType{minecraft:zombie}) mob IDs
✅ Real-time filtering - Changes take effect immediately after using /buffmobs reload

🎮 Configuration Changes

Dimension Scaling - Simplified Values

Dimension scaling now uses direct multipliers instead of percentages for easier configuration:

Before (v2.5.2 and earlier):

healthMultiplier = 200  # 200% = double health
damageMultiplier = 150  # 150% = 1.5x damage

Now (v2.5.3):

healthMultiplier = 2.0  # 2.0 = double health
damageMultiplier = 1.5  # 1.5x damage

This makes the values more intuitive and easier to understand at a glance.

Clean Default Configuration

All configuration lists now start empty by default:

Mob Presets: No default mappings - add only what you need
Mob Filter: Empty blacklist and whitelist by default
Mod ID Filter: Empty lists
Dimension Filter: Empty lists
Custom Ranged Mobs: Empty list

Why this matters: You now have complete control over your configuration without having to remove unwanted default values first.

🐛 Bug Fixes

`/buffmobs reload` Command

Fixed: Command now properly removes buff modifiers before reapplying them
Fixed: Mobs in the blacklist now have their buffs completely removed when you reload
Added: Shows count of buffed vs unbuffed mobs after reload
Added: Properly resets mob health after removing buffs

Debug Command Improvements

Fixed: /buffmobs debug now shows correct mob IDs in both formats
Added: Shows why a mob is filtered (blacklist, whitelist, etc.)
Improved: Better formatting and more detailed information

Configuration Persistenc

Fixed: Changing dimension names no longer resets multipliers
Fixed: All list-based configurations now save properly
Fixed: Configuration changes through Configured mod now persist correctly

📝 Configuration Notes

Important for Existing Users

If you're updating from v2.5.2 or earlier:

Backup your config first: config/buffmobs-common.toml
Delete the old config file to generate the new format
Reconfigure your settings using the new format

Dimension Scaling conversion:

Old 200 (200%) → New 2.0 (2x multiplier)
Old 150 (150%) → New 1.5 (1.5x multiplier)
Old 100 (100%) → New 1.0 (no change)

For New Users

The mod now starts with a completely clean configuration. Simply enable the features you want and configure them to your liking without needing to clear out default values first.

🔍 Testing Your Configuration

After updating, use these commands to verify everything works:

/buffmobs info          - Check current configuration status
/buffmobs debug         - Check a nearby mob's buff status
/buffmobs reload        - Reload all mobs with current config
/buffmobs presets       - View all configured presets

BuffMobs v2.5.1 - Tactical Retreat Update

🎯 What's New

✨ Tactical Retreat System

Ranged mobs (skeletons, piglins, pillagers) can now intelligently retreat when players get too close, creating more dynamic and challenging combat encounters!

New Behavior Modes:

Melee Mode (default): Ranged mobs switch to melee weapons when close, just like before
Retreat Mode (NEW!): Ranged mobs tactically back away 8-12 blocks while continuing to shoot
Random Mode (NEW!): Each mob randomly chooses between melee or retreat behavior when spawned

How it works:

When a player gets within the configured distance (default: 4 blocks), the mob activates its behavior
In Retreat mode, mobs back away for 3 seconds (configurable), then have a 5-second cooldown
Mobs maintain eye contact with the player while retreating
Smart pathfinding ensures mobs don't retreat into walls or dangerous areas

⚙️ New Configuration Options

Ranged/Melee Switching:

behaviorMode: Choose "melee", "retreat", or "random" (default: "melee")
retreatSpeed: How fast mobs retreat (default: 1.2 = 20% faster than normal)
retreatDuration: How long mobs retreat in ticks (default: 60 = 3 seconds)

Example configurations:

# Aggressive melee rushers
behaviorMode = "melee"

# Tactical kiting mobs
behaviorMode = "retreat"
retreatSpeed = 1.5
retreatDuration = 80

# Unpredictable variety
behaviorMode = "random"

🔧 Technical Details

New Files Added:

RangedBehaviorMode.java - Enum defining the three behavior modes
TacticalRetreatGoal.java - Custom AI goal for retreat behavior

Updated Systems:

RangedMobAIManager.java - Now supports all three behavior modes
BuffMobsConfig.java - Added new retreat configuration options
Enhanced mob state tracking to remember chosen behavior

Performance:

Retreat AI only activates when needed
Built-in cooldowns prevent excessive pathfinding calculations
No performance impact when using melee mode

🎮 Use Cases

PvE Difficulty Servers: Use melee mode for aggressive close-combat challenges where skeletons rush players with swords.

Tactical Combat Servers: Use retreat mode to make ranged mobs harder to reach, forcing players to use strategy and positioning.

Variety Servers: Use random mode to keep players on their toes - you never know if a skeleton will charge or kite!

🔄 Compatibility

✅ Fully backward compatible - If you don't change the config, the mod works exactly as before
✅ Works with all existing features - Day scaling, dimension scaling, presets, weapon progression
✅ Works with all supported mobs - Skeletons, Strays, Wither Skeletons, Piglins, Pillagers, and custom ranged mobs

Rebuilt the mod to support Minecraft 1.21.8.
Some features are still limited, like weapon swapping—but the core functionality is working!
Fully integrated with ModMenu, just like previous versions.

Thanks for your patience, and most of all—thanks for downloading my mod! 🎮
Enjoy the game! 😄

🧟 Buff Mobs — Version 2.4.1

🔧 Hotfix Update

This update took a bit longer than usual to release—even though it's technically a hotfix. But good news: it brings important improvements to mob behavior and performance!

✅ What's Fixed

🏃‍♂️ Speed issues on the Fabric version have been resolved.
😡 Mob aggression bugs have been addressed:
- Mobs that should be aggressive in melee combat (like Pillagers) were not attacking properly.
- Mobs without hands (like Witches and Evokers) were not behaving as expected.

🔄 Changes

🧙‍♀️ Witches have been removed from the aggression list.
🏹 Pillagers now have proper aggressive AI behavior.

Everything should be working smoothly now... fingers crossed! 🤞

Melee weapons can spawn with offensive enchantments (Sharpness, Fire Aspect, Knockback, etc.)

Switched weapons cannot be dropped by mobs (no exploit potential)
Compatible with modded ranged mobs through intelligent name pattern detection

Buff Mobs 2.3.0 - NeoForge

by Khotyz on Aug 22, 2025

Download

🔥 BuffMobs v2.3.0 - Major Update!

✨ New Features

🌍 Dimension-Specific Scaling

5 configurable dimension slots - Set unique buff multipliers for specific dimensions!
Smart scaling logic: If main config has buffs, dimension scaling multiplies them. If main config is disabled, dimension scaling applies to vanilla stats
Perfect for modpacks: Make the Nether extra challenging, or buff mobs only in specific dimensions
Examples:
- Nether mobs with 2x health and 1.5x damage
- End mobs with 3x attack speed
- Custom dimension support

🎨 Visual Buff Indicators

Colored particle effects show which buffs mobs have:
- 🔴 Red particles: Health buffs active
- 🟠 Orange particles: Damage buffs active
- 🟡 Yellow particles: Attack speed buffs active
Toggleable per effect type - Enable/disable each visual effect independently
Performance optimized - Particles spawn smartly without lag

🔧 Technical Improvements

⚙️ Enhanced Configuration

Detailed tooltips for all dimension scaling options
Clear examples of dimension names (e.g., minecraft:the_nether)
Better organization with grouped settings
User-friendly descriptions explaining what each multiplier does

🎯 Better Effect Display

Fixed potion effect icons - Now properly shows effect levels (I, II, III, etc.)
Infinity symbol (∞) for permanent effects
Improved visibility of mob status effects

📈 Calculation Formula

The new scaling system works as follows:

Final Value = (Main Config × Dimension Scaling × Day Scaling)

Examples:

Main health = 2.0x, Nether dimension = 1.5x, Day 7 = 1.1x → 3.3x health
Main health = 1.0x (disabled), End dimension = 2.0x → 2.0x health (vanilla base)

🔄 Backwards Compatibility

✅ All existing configs work without changes
✅ Existing features unchanged - day scaling, mob filtering, etc.
✅ Performance maintained - no impact on existing setups
✅ Optional features - new visual effects can be disabled

🛠️ Configuration Examples

Basic Nether Scaling

[dimensionScaling.slot1]
dimensionName = "minecraft:the_nether"
healthMultiplier = 2.0    # Double health
damageMultiplier = 1.5    # 50% more damage

End Game Challenge

[dimensionScaling.slot2]
dimensionName = "minecraft:the_end"
healthMultiplier = 3.0        # Triple health
attackSpeedMultiplier = 2.0   # Double attack speed
armorAddition = 5.0           # +5 armor points

Custom Dimension Support

[dimensionScaling.slot3]  
dimensionName = "twilightforest:twilight_forest"
healthMultiplier = 1.8
speedMultiplier = 1.3

🎮 Perfect For

🏰 Modpack creators wanting dimension-specific difficulty
⚔️ Players who want visual feedback on mob strength
🔧 Server admins needing fine-tuned balance per dimension
📦 Mod integration with custom dimensions

📊 What This Means

More strategic gameplay - Know mob strength at a glance
Better progression - Scale difficulty per dimension naturally
Enhanced immersion - Visual indicators make combat more engaging
Flexible balancing - Perfect control over mob strength anywhere

🎨 New Visual Effects

Custom Status Effects

We've added 3 new custom visual effects that appear on buffed mobs to help you identify their enhanced abilities:

✨ Enhanced Vitality

Color: Red (❤️)
Shows when: Mobs have increased health
What it means: This mob has more HP than usual - expect a longer fight!

⚔️ Combat Fury

Color: Orange (🔥)
Shows when: Mobs have increased attack speed
What it means: This mob attacks faster - keep your distance!

💥 Destructive Power

Color: Dark Red (💀)
Shows when: Mobs have increased damage
What it means: This mob hits harder - better armor recommended!

🔧 Technical Improvements

Code Architecture:

DimensionScalingUtil - New utility class for dimension-aware scaling calculations
Modular design - Better separation of concerns between different scaling systems
Performance optimizations - More efficient attribute calculation and caching
Error handling - Improved error handling and logging throughout the mod

Compatibility:

Fabric API - Uses latest Fabric API features
Mod Menu 11.0+ - Compatible with latest Mod Menu versions
Cloth Config 15.0+ - Uses modern Cloth Config API

📝 Configuration Examples

Basic Dimension Scaling Setup:

Slot 1:
- Dimension Name: minecraft:the_nether
- Health Multiplier: 2.0
- Damage Multiplier: 1.5
- Speed Multiplier: 1.2

Advanced Multi-Dimension Setup:

Slot 1: minecraft:the_nether (High difficulty)
Slot 2: minecraft:the_end (Extreme difficulty)  
Slot 3: modpack:custom_dimension (Custom scaling)
Slot 4: (Available for future dimensions)
Slot 5: (Available for future dimensions)

🎯 How It Works

The new dimension scaling system works multiplicatively with base settings:

If base Health = 2.0x and Nether scaling = 1.5x
Final Nether Health = 3.0x (2.0 × 1.5)
Day scaling still applies on top of dimension scaling
Armor values are additive instead of multiplicative

🚀 Getting Started

Install the mod and launch Minecraft
Open Mod Menu from the main menu or pause screen
Find BuffMobs in the mod list
Click the config button to open the configuration screen
Configure dimension scaling in the new "Dimension Scaling" category
Save and enjoy enhanced mob difficulty per dimension!

Note: This update maintains full backward compatibility with existing configurations. Your current settings will be preserved and work exactly as before, with the new dimension scaling features available as optional enhancements.
