AntiAFKPlus v2.9.5 Compatibility Compatible with Minecraft Java Edition 26.1 and 26.1.1 Changes Fixed a chat-related issue that caused warnings in the console on modern servers

AntiAFKPlus v2.9.5 - UPDATE NOTE

⚠️ IMPORTANT NOTICE: This is the last free version of AntiAFKPlus.

Due to a lack of support and high maintenance volume, the project will evolve to a Premium model starting with version 3.0.

What does this mean? This version (2.9.5) will continue to function, but new features, optimizations, and technical support will be exclusively available in the paid version. There will be no further updates, maintenance, or support for this version.

More info: Join our Discord server for details about the v3.0 release.

I am deeply grateful to the few people who have always been there supporting us with positive words. Those who wish to continue enjoying new features and ongoing support are welcome in this new phase.

Version: 2.9.3
Release Date: December 30, 2025
Compatibility: Minecraft 1.16 - 1.21.11
Java: 17+

AntiAFKPlus v2.9.2 — Dynamic Credit Group Detection & Multi-Server Documentation

Release type: Bugfix & Enhancement Compatibility: Minecraft 1.16 – 1.21.11 | Java 17+

---

What's Fixed

🔧 Credit System Group Detection

• Dynamic Group Reading: Plugin now automatically detects ALL groups defined in credit-ratios and max-credits config sections
• No More Hardcoded Limitations: Previously only supported admin, premium, and vip groups — now supports unlimited custom groups
• Custom Group Support: Works with any group name: sponsor, premium+, vip+, owner, member, etc.
• Permission Format: Uses antiafkplus.credit.ratio.<groupname> pattern (e.g., antiafkplus.credit.ratio.sponsor)
• Priority System: Implements configurable group priority order (admin > owner > sponsor > premium+ > vip+ > premium > vip > default)

📝 Technical Improvements

• Added dynamic ConfigurationSection reading for group detection
• Implemented intelligent caching system for group priority calculations
• Cache automatically clears on /afkplus reload for instant config updates
• Enhanced debug logging to show matched groups per player
• Improved error handling with fallback to default values

---

What's Documented

🌐 Multi-Server Credit System Setup

• Fully Documented: Complete documentation for running multiple servers (Skyblock, Survival, etc.) with separate credit systems sharing one database
• Table Prefix Feature: Use table-prefix config option to separate credit tables per server
• Configuration Examples: Step-by-step guides added to config.yml and README.md
• New Documentation File: MULTI_SERVER_DOCUMENTATION.md with complete setup guide, troubleshooting, and security best practices

How It Works:

• Each server uses a different table-prefix (e.g., skyblock_, survival_)
• All servers connect to the same MySQL/SQLite database
• Credits are completely independent per server
• No code changes needed — configuration only!

---

Configuration Example

credit-system:
  credit-ratios:
    default: '5:1'
    vip: '4:1'
    premium: '3:1'
    premium+: '2:1'
    sponsor: '1:30'     # ✅ Now works!
    owner: '1:60'       # ✅ Custom groups supported!

  max-credits:
    default: 120
    vip: 180
    premium: 240
    sponsor: 500
    owner: 1000

  # Optional: Customize priority order
  group-priority-order:
    - owner
    - admin
    - sponsor
    - premium+
    - vip+
    - premium
    - vip

Multi-Server Setup Example

Skyblock Server (config.yml):

credit-system:
  database:
    enabled: true
    table-prefix: "skyblock_"  # Skyblock tables

database:
  type: "MySQL"
  mysql:
    host: "localhost"
    database: "antiafkplus"

Survival Server (config.yml):

credit-system:
  database:
    enabled: true
    table-prefix: "survival_"  # Survival tables

database:
  type: "MySQL"
  mysql:
    host: "localhost"
    database: "antiafkplus"  # Same database!

Result: Independent credit systems (skyblock_credits, survival_credits) in one shared database.

Permission Setup (LuckPerms Example)

/lp group sponsor permission set antiafkplus.credit.ratio.sponsor true
/lp group premium+ permission set antiafkplus.credit.ratio.premiumplus true

Note: Plus signs (+) in group names convert to plus in permission nodes.

---

Compatibility

• Minecraft: 1.16 – 1.21.11
• Platforms: Bukkit, Spigot, Paper, Purpur, Folia
• Java: 17+
• Permission Plugins: LuckPerms, PermissionsEx, GroupManager, etc.
• Fully Backward Compatible: Existing configurations continue to work

---

Upgrade Notes

1. Replace the old JAR with AntiAFKPlus v2.9.2
2. Update LuckPerms (or other permission plugin) with new group permissions:
   • Format: antiafkplus.credit.ratio.<groupname>
3. Optional: Customize group priority order in config.yml
4. NEW: Check config.yml for multi-server table-prefix examples if you run multiple servers
5. Reload with /afkplus reload to apply changes
6. Enable debug: true in config to verify group detection

Existing admin, premium, and vip groups continue to work without changes. New custom groups require permission node setup.

Multi-Server Users: If you want to separate credit systems across multiple servers, configure different table-prefix values in each server's config.yml (see documentation).

---

For Developers

API Version: 2.9.2 (unchanged API, internal improvements only)

No breaking changes to the public API. The credit system now uses dynamic group detection internally, improving flexibility for server administrators.

AntiAFKPlus v2.9.1 — Pattern Detection Respecting Config

Release type: Bugfix Compatibility: Minecraft 1.16 – 1.21.10 | Java 17+

---

What's Fixed

• Pattern Detection now fully honors config/module toggles; disabling the module or enhanced-detection.pattern-detection stops analysis and prevents flags/actions.
• Detector uses all configured thresholds (interval, sample counts, repetitive/area limits, large-pool and keystroke toggles) instead of hardcoded defaults.
• /afkplus reload cleanly restarts or shuts down pattern analysis to reflect updated settings without a server restart.

---

Upgrade Notes

1. Replace the old JAR with AntiAFKPlus v2.9.1.
2. Reload with /afkplus reload or restart.
3. Verify your modules.pattern-detection and pattern-detection-settings values; they are now enforced.

---

Compatibility

• Minecraft: 1.16 – 1.21.10
• Platforms: Bukkit, Spigot, Paper, Purpur, Folia
• Java: 17+
• Backward Compatible: All existing configurations work without changes

---

Upgrade Notes

1. Replace the old JAR with AntiAFKPlus v2.9
2. Optional: Configure afk-windows section in config.yml to enable time-based protection
3. Optional: Customize the afk-window-active message in messages.yml for localization
4. Update your dependency to 2.9 if using the API:

   <dependency>
       <groupId>com.github.koyere</groupId>
       <artifactId>AntiAFKPlus</artifactId>
       <version>2.9</version>
       <scope>provided</scope>
   </dependency>
   

No configuration changes are required. The plugin works with your existing setup. AFK windows are disabled by default.

---

For Developers

API Version: 2.9 (unchanged from 2.8, no breaking changes)

The time window system is internal and transparent to the API. Developers using the API will benefit from the improved flexibility without code changes.

---

Version: 2.9 Release Date: 14/11/2025 Compatibility: Minecraft 1.16 - 1.21.10 Java: 17+

AntiAFKPlus v2.8.2 (Hotfix Rollup)

Bug Fixes

• Pause-aware scheduling – Introduced a shared ServerStateUtil and wrapped every repeating task scheduled through PlatformScheduler so they no longer spin while Paper/Folia is paused or running in auto-pause mode. This eliminates the repeated CPU spikes reported when the server was suspended.
• Stable transfer countdowns – Countdown sequences now persist their start timestamp and AFK state. Players that have not produced real activity after the countdown started will no longer flip back to ACTIVE each tick, so the “title disable kick / activity detected loop” is gone and the final action fires exactly once.

These fixes are fully backwards compatible with the v2.8 API—only internal scheduling and AFK state transitions were touched.

AntiAFKPlus v2.8.1 - Critical Threading Fix

Release Date: 2025-10-20 Type: Bugfix Release Compatibility: Paper 1.21.8, Spigot, Folia, Purpur (MC 1.16-1.21.8)

---

🔧 Critical Fixes

Pattern Detection Event Threading (Paper 1.21.8 Compatibility)

Issue: Pattern detection events were being fired asynchronously, causing IllegalStateException on Paper 1.21.8 and preventing external API listeners from receiving events.

Fixed:

• ✅ All Bukkit events now fire synchronously on main thread (Paper 1.21.8 requirement)
• ✅ Eliminated async entity access (player.getLocation() now called in main thread)
• ✅ Converted internal data structures to thread-safe collections (ConcurrentHashMap/ConcurrentLinkedDeque)
• ✅ Implemented atomic operations for violation counters to prevent race conditions
• ✅ Added proper player disconnect handling during async analysis

Impact:

• External plugins using api.registerPatternDetectionListener() now receive events correctly
• Zero threading exceptions in Paper 1.21.8+
• Maintained performance (heavy analysis still runs asynchronously)

Files Changed:

• PatternDetector.java - Complete threading model refactor

---

📊 Performance

• ✅ Zero performance regression - Pattern analysis remains asynchronous
• ✅ Thread-safe operations - All concurrent access properly synchronized
• ✅ Folia compatible - Uses runTaskForEntity for player-specific operations

---

🔗 API Compatibility

Fully compatible with v2.8 API - No breaking changes for developers.

Developers can now safely use:

AntiAFKPlusAPI api = AntiAFKPlusAPI.getInstance();
api.registerPatternDetectionListener(event -> {
    // This now works correctly on Paper 1.21.8+
    System.out.println("Pattern detected: " + event.getPattern().getType());
});

---

Release type: Feature & API Upgrade Compatibility: Minecraft 1.16 – 1.21.10 | Java 17+

---

What's New

📊 Real Data Everywhere

• Activity, history, and statistics endpoints now return live server data.
• getActivityInfo, getActivityStatistics, getAFKStatistics, getPlayerStatistics, and getAFKHistory consume the internal tracking system (no more placeholders).

🚦 Reliable Events

• AFK warnings and pattern detections are always delivered to the public API.
• Listeners (registerWarningListener, registerPatternDetectionListener) can modify messages or cancel actions before the plugin kicks/teleports players.

🗺️ Zone Awareness

• New helpers (isAFKAllowedAt, getAFKZoneAt) resolve zone-management settings and WorldGuard regions on the fly.
• Worlds can be toggled at runtime with setAFKDetectionEnabled, persisting the change to config.yml.

⚙️ Ease of Use

• README/API docs include updated examples for the new endpoints (activity, zones, stats).
• API version bumped to 2.8, ready for your integrations.

---

Upgrade Notes

1. Replace the old JAR with AntiAFKPlus v2.8.
2. Update your dependency to 2.8 (Maven/Gradle snippet in the README).
3. Review the new API examples and adjust your listeners if you want to react to warnings/patterns.

No configuration changes are required. Everything works with your existing config.yml / messages.yml.

#v2.7.1 - Thread Safety Fix

##Fixed ConcurrentModificationException in PatternDetector.detectPendulumPattern() that caused random crashes during pattern analysis. Added defensive list copying for thread-safe movement history access, improving reliability of the AFK event system.

AntiAFKPlus v2.7 — Critical Bug Fixes

Release type: Bug Fix Release Compatibility: Minecraft 1.16 – 1.21.9+ | Java 17+

---

What's Fixed

🔧 Credit System Teleportation (CRITICAL FIX)

Problem: AFK zone teleportation worked only 1-2 times, then stopped working. Players would see AFK warnings but never get teleported.

Solution: Fixed credit system logic to properly teleport players when credits are exhausted.

What this means for you:

• ✅ AFK zone teleportation now works consistently every time
• ✅ Credits consume properly minute-by-minute while AFK
• ✅ Players are automatically teleported when credits reach zero
• ✅ No more "stuck" players who see warnings but never get moved

---

🌍 Disabled Worlds Cleanup (CRITICAL FIX)

Problem: Players still received AFK warnings in disabled worlds (like luna-afk-1), even when those worlds were added to disabled-worlds configuration.

Solution: Plugin now completely clears AFK state when players enter disabled worlds.

What this means for you:

• ✅ No more AFK warnings in disabled worlds
• ✅ AFK state is automatically cleared when entering disabled worlds
• ✅ Works correctly with both disabled-worlds and enabled-worlds configuration
• ✅ Players can safely AFK in designated worlds without interference

---

🐛 Pattern Detection Errors (TECHNICAL FIX)

Problem: Server logs showed ConcurrentModificationException errors during pattern analysis.

Solution: Implemented thread-safe pattern detection across all detection methods.

What this means for you:

• ✅ Clean server logs without errors
• ✅ Pattern detection (water circles, large pools, confined spaces) works flawlessly
• ✅ Better server stability and performance
• ✅ No more error spam in console

---

⚙️ Credit System Isolation (ENHANCEMENT)

Problem: Credit system could potentially interfere with standard AFK detection even when disabled.

Solution: Complete isolation of credit system when disabled in configuration.

What this means for you:

• ✅ Zero performance overhead when credit system is disabled
• ✅ Standard AFK detection works perfectly without credit system
• ✅ Full backwards compatibility with previous configurations
• ✅ Better resource efficiency

---

Configuration Examples

Fix #1: Enable AFK Zone Teleportation with Credits

modules:
  credit-system:
    enabled: true

credit-system:
  enabled: true
  afk-zone:
    enabled: true
    world: "world"
    location: "0,100,0"

Fix #2: Disable AFK Detection in Specific Worlds

disabled-worlds:
  - "luna-afk-1"
  - "creative-world"
  - "lobby"

---

Upgrade Instructions

• AFK zone teleportation now reliable and consistent
• Disabled worlds work as expected (no more false warnings)
• Eliminated concurrent modification errors in logs
• Credit system properly isolated when disabled

Performance:

• Thread-safe operations throughout pattern detection
• Reduced resource usage when credit system is disabled
• Cleaner logs and better stability

Version: 2.7 Release Date: October 12, 2025 Type: Critical Bug Fix Release

AntiAFKPlus v2.6 — Server Transfer & Scripted Sequences

Release type: Feature Release
Compatibility: Minecraft 1.16 – 1.21.8+ | Java 17+

What’s New

Server Transfer (Bungee/Velocity)

• Native final action TRANSFER_SERVER to move AFK players to another server via Plugin Messaging.
• Global configuration with robust channel handling and optional retry policy.
• Zone-based overrides: per-zone transfer with kick-action: TRANSFER and transfer-server.

Countdown & Titles/Sounds

• Optional per-second countdown with Title/Subtitle and Sound before transferring.
• Fully Folia-safe with entity-bound scheduling.
• Auto-cancels if the player becomes active.

Scripted Action Pipeline

• New pipeline engine to run steps in order: TITLE, SUBTITLE, SOUND, MESSAGE, WAIT, TRANSFER.
• Configurable in config.yml with simple DSL-like syntax.
• Cancels automatically when leaving AFK.

Robustness & Fallbacks

• Auto-registration of BungeeCord and bungeecord:main channels.
• Channel selection: auto | bungeecord | namespaced.
• Fallback actions: KICK | TELEPORT | NONE with optional teleport location.

How It Works (Action Order)

1. Credit System: If credits exist, the kick event is cancelled and credits are consumed; no transfer runs.
2. Zone Management: Zone kick-action takes priority (TELEPORT, TRANSFER, etc.).
3. Global Transfer: If enabled and a target-server is configured, TRANSFER_SERVER is used by default.

If the player becomes active mid-flow, any countdown/pipeline is cancelled.

Configuration

Global settings:

server-transfer:
  enabled: true
  target-server: "lobby"
  proxy-channel: "auto"        # auto | bungeecord | namespaced

  # Fallbacks
  fallback-action: "KICK"      # KICK | TELEPORT | NONE
  fallback-teleport-location: "world,0,100,0"

  # Retry policy
  retry-attempts: 0
  retry-delay-ticks: 10

  # Countdown
  countdown:
    enabled: false
    seconds: 10
    title: "&cYou are AFK"
    subtitle: "&eMoving in {seconds}s"
    sound:
      enabled: true
      name: "ENTITY_EXPERIENCE_ORB_PICKUP"
      volume: 1.0
      pitch: 1.0

  # Scripted pipeline
  pipeline:
    enabled: false
  actions:
    - "TITLE: &cYou are AFK"
    - "SUBTITLE: &eMoving in {seconds}s"
    - "SOUND: ENTITY_EXPERIENCE_ORB_PICKUP,1.0,1.0"
    - "WAIT: 1s"
    - "MESSAGE: &7Transferring..."
    - "TRANSFER: lobby"

Zone-based transfer example:

zone-management:
  enabled: true
  zones:
    spawn:
      kick-action: "TRANSFER"
      transfer-server: "lobby"

Messages

Add or customize in messages.yml:

messages:
  server-transfer:
    transferring: "&7[AntiAFK+] &aTransferring you to &f{server}&a..."
    unavailable: "&7[AntiAFK+] &cServer transfer unavailable."
    failed: "&7[AntiAFK+] &cCould not transfer you."

Permissions & Commands

• No new commands or permissions in v2.6. The feature is fully configurable via config.yml.

Compatibility & Notes

• BungeeCord and Velocity (Bungee compatibility) via Plugin Messaging.
• Folia-safe scheduling through PlatformScheduler; no BukkitScheduler in Folia context.
• Fully backward compatible; disabled by default.

Migration

• No breaking changes. Existing configurations remain valid.
• To enable: set server-transfer.enabled: true and configure target-server.

Testing Checklist

• Validate transfer on Bungee/Velocity with correct target-server names.
• Try countdown and pipeline separately.
• Confirm fallback behavior (KICK/TELEPORT/NONE) when channels are unavailable.
• Verify zone-based TRANSFER overrides global behavior.

AntiAFKPlus v2.5 — Release Notes

🎯 AFK Credit System - Earn Time to Be Away

New Feature Overview

Revolutionary AFK Credit System: Players can now earn AFK time by being active! For every X minutes of active gameplay, players earn Y minutes of AFK allowance before being teleported to a designated AFK zone.

What’s New

1. AFK Credit Earning System

• Players earn AFK credits by being actively engaged in gameplay
• Configurable credit ratios based on permissions (default: 5 minutes active = 1 minute AFK credit)
• Real-time credit accumulation tracking with activity validation
• Maximum credit limits to prevent indefinite accumulation

2. Credit-Based AFK Protection

• When a player goes AFK, the system first consumes available credits
• Credits provide immunity from immediate kick/teleportation
• Once credits are exhausted, player is teleported to designated AFK zone
• Smooth transition from credit consumption to zone teleportation

AFK Credit System

• Earn credits while active; consume credits to delay AFK action.
• Teleport to AFK zone when credits are exhausted; /afkback returns you.

WorldGuard Integration

• Zones resolved from regions (reflection, no hard dependency).
• Teleport priority: zones.afk → zones.spawn → credit-system.afk-zone.

AFK Zone Protection

• Optional damage/PVP/mob-spawn protections near the AFK zone.

SQL History (Optional)

• Track earn/consume/admin/decay transactions when SQL is enabled.

New Placeholder

• %antiafkplus_credits_expire_days% — days until credits expire.

---

How It Works

1. Active players earn credits (ratio-based) up to a configurable cap.
2. When AFK is detected, 1 credit/minute is consumed to delay the action.
3. At 0 credits, the player is teleported to the AFK zone; /afkback returns them.

• onAfkStateChange (MONITOR): stops consumption when returning to ACTIVE.
• CreditData (new):
  • Balance, consumption state, per‑player task, original location (for return).

    zone-teleport: "&7[AntiAFK+] &aTeleported to AFK zone."
    errors:
      invalid-location: "&7[AntiAFK+] &cInvalid AFK zone location configured."

Permissions (declared)

• antiafkplus.credit.earn — earn credits (default true)
• antiafkplus.credit.use — use credits to delay AFK action (default true)
• antiafkplus.credit.ratio.vip|premium|admin — improved ratios (default false/op)
• antiafkplus.credit.admin — full credit administration

Execution Flow

1. Active player earns credits according to ratio and limits.
2. On AFK, if credits available → cancel action and consume 1/min.
3. On activity → stop consumption (no teleport).
4. On exhaustion → teleport to AFK zone (zone‑management if present; fallback to credit-system.afk-zone).

Compatibility & Performance

• Folia‑safe (no BukkitScheduler in Folia context).
• No changes to AFKManager loop (event‑driven).
• Earning: one global job/min; consumption: per‑player task while AFK with balance.
• Respects antiafkplus.bypass.

🎯 Credit System Logic Flow

1. Credit Earning Process:

Player Active (5 minutes) → Activity Validation → Credit Calculation → Credit Award
                         ↓
Activity Score Check → Pattern Detection → Anti-Abuse Validation → Credit Storage

2. AFK Detection with Credits:

Player Goes AFK → Check Credit Balance → Has Credits? 
                                      ↓
               Yes: Consume Credits → Continue Monitoring
                                      ↓
               No: Save Location → Teleport to AFK Zone → Enable Return Command

3. Return Process:

Player Uses /afkback → Validate in AFK Zone → Check Original Location Safety
                                           ↓
                    Safe: Teleport Back → Clear AFK Status → Success Message
                                           ↓
                    Unsafe: Teleport to Spawn → Warning Message

AntiAFKPlus v2.4.2 Changelog

🎯 Complete Folia 1.21.8 Compatibility

Problem Resolved

Issue: The plugin failed to initialize on Folia 1.21.8 with UnsupportedOperationException (due to BukkitScheduler usage) and reflection errors in runAtFixedRate.

Root Cause: PlatformScheduler was using incorrect method signatures for Folia's GlobalRegionScheduler API, causing reflection failures during task scheduling.

Error Stack:

Failed to schedule Folia repeating task: io.papermc.paper.threadedregions.scheduler.FoliaGlobalRegionScheduler.runAtFixedRate
Module system initialization failed: Cannot schedule repeating task on Folia without working scheduler

Technical Solution Implemented

🔧 Correct Folia Method Signatures

• Before: runAtFixedRate(plugin.getClass(), Consumer.class, long.class, long.class, TimeUnit.class)
• After: runAtFixedRate(Plugin.class, Consumer.class, long.class, long.class)
• Key: no TimeUnit parameter and timing in ticks directly (no ms conversion)

🛡️ Stronger Fallback

• Always create a ScheduledExecutorService fallback before reflection
• Graceful degradation if native Folia API fails
• Dedicated daemon thread pool for fallback operations

⚡ Additional API Fixes

• Adjusted runDelayed and run signatures for single-execution tasks
• Corrected RegionScheduler and EntityScheduler parameter types
• Consistent use of Consumer<ScheduledTask>

What’s Fixed

• ✅ Full Folia 1.21.8 compatibility: initializes and runs correctly
• ✅ No UnsupportedOperationException: removed BukkitScheduler usage in Folia context
• ✅ Timers and tasks migrated to PlatformScheduler: pattern analysis, detectors and checks operational
• ✅ Commands and AFK detection working
• ✅ Zero impact on other servers: Paper, Spigot, Bukkit, Purpur unchanged

Compatibility

• Paper/Spigot/Bukkit: ✅ unchanged, functionality preserved
• Purpur: ✅ compatible via Paper base
• Folia 1.21.8+: ✅ complete native support with correct API usage

Version: 2.4.2
Release Date: 2025-09-09
Compatibility: Minecraft 1.16 - 1.21.8
Java: 17+

Upgrade Instructions

1. Download AntiAFKPlus v2.4.2
2. Replace the old JAR in /plugins
3. Restart the server
4. No configuration changes required
5. On Folia, verify the log: “✅ Folia support initialized successfully”

AntiAFKPlus v2.4.1 Changelog

🐛 Critical Bug Fix

Issue Resolved

Problem: Players were being kicked/teleported repeatedly every 5 seconds instead of only once after reaching the AFK timeout threshold.

Root Cause: The AFK check task was calling the kick/teleport action repeatedly during each check interval (every 5 seconds) instead of executing it only once per AFK session.

Solution Implemented

🔧 Technical Fix

• Added action state tracking to prevent repeated kick/teleport actions for the same AFK session
• Implemented safety delay to prevent immediate actions upon AFK detection
• Added automatic cleanup of action state when players become active again
• Maintained full compatibility with all existing features and API

✅ Result

• Players are now kicked/teleported only once after reaching their AFK timeout
• AFK timeout configurations (like default-afk-time: 600) now work correctly
• All other plugin functionality remains unchanged and fully operational

---

Version: 2.4.1
Release Date: 2025-09-06
Type: Critical Bug Fix
Compatibility: Minecraft 1.16 - 1.21.8 Java: 17+

Upgrade Notes

• No configuration changes required
• Fully backward compatible
• Simply replace the JAR file and restart your server

AntiAFKPlus v2.4 Changelog

🎯 Large AFK Pool Detection Enhancement

Problem Identified

Issue: Players were bypassing AFK detection by creating large AFK pools (20x10+ blocks) that circumvented existing detection systems.

Root Cause:

• Current detection focused on small confined spaces (≤5x5 blocks) and water circles (≤3 block radius)
• Large pools allowed players to move naturally via water currents without manual input
• System detected movement but couldn't distinguish between manual keystrokes and automatic water current movement

Solution Implemented

🔧 New Detection Features

1. Keystroke Timeout Detection

• Added detection for players who don't provide manual keyboard input for extended periods
• Distinguishes between manual WASD movement and automatic water current movement
• Configurable timeout threshold (default: 3 minutes)

2. Large AFK Pool Pattern Recognition

• Expanded detection to identify pools between 5x5 and 25x25 blocks
• Analyzes movement patterns to identify water current automation
• Multi-factor validation prevents false positives

3. Enhanced Movement Analysis

• Velocity analysis to detect consistent water current speeds
• Direction change analysis to identify artificial vs natural movement
• Automatic vs manual movement classification

📋 Technical Changes

Files Modified:

• MovementListener.java: Added keystroke detection and movement analysis
• PatternDetector.java: Implemented large pool detection algorithms
• config.yml: Added configuration options for new detection methods

New Configuration Options:

pattern-detection-settings:
  large-pool-threshold: 25.0  # Maximum area for large AFK pools
  keystroke-timeout-ms: 180000  # 3 minutes without manual input
  automatic-movement-velocity-threshold: 0.15  # Water current detection

🎮 Detection Logic

Large AFK Pool Detection Criteria:

1. Movement area > 5x5 but < 25x25 blocks
2. Player in water for extended periods
3. Movement patterns consistent with water currents
4. No manual keystrokes detected for 3+ minutes

Only triggers AFK when ALL criteria are met, ensuring legitimate gameplay is not affected.

✅ Benefits

• Closes bypass loophole: Large AFK pools (20x10+) are now detected effectively
• Maintains accuracy: Multi-factor validation prevents false positives
• Configurable: Server owners can adjust thresholds based on their needs
• Performance optimized: Minimal impact on server performance
• Backward compatible: All existing detection methods remain unchanged

Version: 2.4
Release Date: 2025-08-07
Compatibility: Minecraft 1.16 - 1.21.8 Java: 17+

Update 2.3

World Teleportation Fix

AFK players can now teleport instead of being kicked:

• Enabled the necessary AFK zone modules
• Set your coordinates: world, 167, 104, 206

Safety features included:

• Validation of existing world
• Fallback to spawn if there are coordinate errors
• Protection against teleporting to the void

Now checks your spawn zone before the kick >>> Read the action: teleport config >>> Set the event to teleport instead of kicking

Bug Fixes

• Fixed an error with the reload command.
• Fixed an error in the asynchronous data console.
• Fixed an identified memory leak issue.

It is recommended to update to the latest available version to avoid critical errors. No further updates or fixes are required.
