VirgolaAntiCheat -----
Complete and modern AntiCheat for Paper 1.21.x, with GUI and automatic ban system!Bug Fixes
Global Improvements & Bug Fixes:
- False Positive Reduction:
All checks now distinguish between real cheating attempts and legitimate player actions, drastically reducing false positives.
- Performance Optimization:
Switched to thread-safe data structures (ConcurrentHashMap, etc.), and offloaded heavy checks to async tasks wherever possible for better server performance.
- Config-Driven:
All thresholds, cooldowns, warning amounts, and detection parameters are now fully configurable via ChecksConfig.
- Consistent Messaging & Logging:
Improved alert, action bar, warning, and log messages with more detailed placeholders for easy debugging.
- Bypass Handling:
Players with the bypass permission or in Creative/Spectator mode are always correctly excluded from checks.
- Better Thread Safety:
All shared state is properly synchronized.
- No more alerts for inventory interaction or head movement:
Detection now triggers only if the player actually walks (moves in X/Z coordinates) with the GUI open, not just by moving their view or interacting with inventory slots.
- Buffer after inventory open:
Added an 850ms buffer after opening inventory to prevent instant false alerts.
- Packet-based precision:
When ProtocolLib is available, movement is tracked directly at the packet level for maximum accuracy.
- Less spam:
Alert cooldown and GUI open buffer fully configurable.
- Dual-Mode Detection (Events + ProtocolLib):
The check works both with Bukkit events and ProtocolLib packets for maximum compatibility and accuracy.
- Accurate Fall Distance:
Accumulates real fall distance, considers boots with Feather Falling and Slow Falling effect, and never triggers for falls onto safe blocks (water, slime, ladders, vines, boats, minecarts, etc.).
- False positive reduction:
Properly resets fall state on safe landing, disables itself when needed, and avoids alerting when players take legitimate no-damage falls.
- Async computation:
All heavy calculations and alerts happen async, reducing main thread lag.
- Accurate Break Time Calculation:
Checks block hardness, tool type, enchantments, potion effects (Haste/Mining Fatigue), and block drops to determine if breaking time is legit.
- Supports both Bukkit and ProtocolLib event flows.
- Soft block handling:
Special logic for softer blocks and multi-platform support.
- Spam reduction:
Alert cooldown and tolerance thresholds prevent alert flooding.
- Thread safety:
All relevant maps and data stores are thread-safe.
- Directional attack detection:
Uses field-of-view, dot product, and yaw angle to check if the target is within legitimate attack range, and not behind or outside player’s view.
- No alerts for close-proximity (legit) attacks.
- Supports both ProtocolLib and event-based flows.
- Checks only legitimate attack events:
Verifies that the attack is of type ENTITY_ATTACK and that the reach distance exceeds the configured threshold.
- Cooldown per player to prevent warning spam.
- Never triggers in Creative/Spectator or for bypass players.
- Reliable fluid-walking detection:
Triggers only if the player is genuinely walking over a fluid block (not inside it or on the edge), and only if not gliding, flying, or affected by Levitation.
- Cleans up state as needed to prevent memory leaks and false alerts.
- All checks and alerts are performed in an async-safe manner.
- Variance-based detection:
Looks for suspiciously consistent click intervals (low variance) and high CPS before flagging.
- Auto-resets state on inactivity or if the player is mining, to avoid accidental alerts.
- CoolDown configurable per player.
- Much fewer false positives for all checks.
- Better user experience: inventory is fully usable, fewer unnecessary warnings, and player actions are not interrupted.
- Increased accuracy and configurability.
- Optimized performance and stability.
- Cleaner, more maintainable code.
