SentialAnticheat

SentialAnticheat – Advanced Anti-Cheat Plugin
SentialAnticheat is a modern, high-performance anti-cheat solution for Minecraft servers. It is designed to catch a wide range of cheats while remaining lightweight and configurable.

⚠️ Important Note: This plugin is still in active development. The current systems are functional, but not all are fully stable yet. The focus right now is on perfecting existing checks and reducing false positives. More checks and refinements will be added once the current detections are stable.

Detection Systems
Combat Checks
KillAura Detection

• Aim Consistency Tracking: Detects robotic precision and perfect aim corrections.
• Target Switching: Flags suspiciously fast switching between multiple entities.
• Hit Pattern Analysis: Identifies impossible timing sequences or mechanical attack rhythms.
• Reach Validation: Ensures hits are within legitimate vanilla reach limits.
  

Reach Detection

• Measures exact hit distances to detect extended reach attacks.
• Adjusts for latency, knockback, and hitbox variations.
  

Movement Checks
Speed Detection

• Monitors player movement speed in all states (walking, sprinting, sneaking, swimming, flying).
• Detects speed modifications while accounting for potions, terrain, and equipment.
  

NoFall Detection

• Validates fall distance and landing impact.
• Detects attempts to bypass fall damage through packets or modified clients.
  

Fly Detection

• Identifies unauthorized vertical movement, hovering, or flight mechanics.
• Compares player motion against vanilla flight states (elytra, creative mode, levitation effects).
  

World Interaction Checks
Xray Detection

• Ore Frequency Analysis: Tracks mining ratios to detect impossible ore discovery.
• Exposure Validation: Confirms ores were visible or exposed before mining.
• Vein Pattern Analysis: Identifies unnatural ore targeting.
• Statistical Modeling: Differentiates lucky players from cheaters.
  

Nuker Detection

• Detects abnormally fast block breaking rates.
• Flags unnatural breaking patterns across multiple directions.
• Validates block hardness to ensure break times are legitimate.
  

Scaffold Detection

• Monitors block placement speeds and timings.
• Flags placements at impossible angles or mid-air.
• Detects automated bridging movement patterns.
  

Automation & Macro Checks
AutoFish Detection

• Analyzes fishing rod usage and timing.
• Detects automated casting, reeling, and perfect timing loops.
  

AutoClicker Detection (in development)

• Tracks click intervals for robotic consistency.
• Detects lack of human variance in click patterns.
  

Bot & Automation Checks
BotFlood Detection

• Identifies mass-connection bot attacks.
• Tracks suspicious usernames, join patterns, and IP addresses.
• Differentiates between legitimate players and bot swarms.
  

Baritone Detection

• Monitors pathing behavior that resembles AI-driven navigation.
• Detects repetitive, perfect block-breaking paths.
• Flags players executing inhuman mining/building patterns.
  

System Requirements

• Minecraft Version: 1.21+
• Server Software: Paper/Spigot
• Dependencies:
  • ProtocolLib 5.4.0+
  • Java 17+
    

Administration
Commands

• /ac reload – Reloads configuration.
• /ac debug <player> – Toggles debug mode for a specific player.
• /ac stats [player] – View violation statistics.
  

Permission Nodes

• sentialanticheat.bypass – Bypass all checks.
• sentialanticheat.alerts – Receive violation alerts.
• sentialanticheat.commands – Use admin commands.
• sentialanticheat.notify – Receive system notifications.
  

Configuration
SentialAnticheat is designed with server flexibility in mind. Each check can be configured or adjusted in the config.yml to fine-tune thresholds, violation levels, and alert settings to best suit your server’s needs.

Development Status
SentialAnticheat is not complete yet. The following systems are currently implemented:

• Xray
• Scaffold
• Nuker
• Speed
• NoFall
• Fly
• Reach
• KillAura
• BotFlood
• Baritone
• AutoFish
  

Additional checks (such as FastPlace, AutoClicker, Phase, and more) will be developed once the current detections reach stable production quality.
