# Closure<\/p>\n
Closure is a hybrid anti-cheat plugin currently in early Alpha. It attempts to solve a common problem in Minecraft server administration:
\n the balance between blocking cheaters and not punishing legitimate players causing false positives due to lag.<\/p>\n
Most anti-cheats rely solely on static thresholds (e.g., “if player moves > X speed, pull them back”). Closure adds a statistical layer to
\n this process. It tracks player behavior over time\u2014aim consistency, packet order, and movement patterns\u2014to build a “confidence score.”<\/p>\n
This score doesn’t ban players on its own. Instead, it adjusts the strictness of the core physics checks. If a player has a history of
\n legitimate movement, the system grants them a small buffer to account for lag spikes. If a player shows robotic consistency or impossible
\n reaction times, that buffer is removed, and enforcement becomes instant.<\/p>\n
# Current Features (Alpha)<\/p>\n
* 1.21+ Support: Uses ProtocolLib to handle modern packet structures (including the new Velocity\/Shorts format).
\n * Shadow Player: A specialized verification check for KillAura. It spawns a fake player entity (visible in the tab list, wearing armor)
\n that lunges at the suspect to trigger “self-defense” modules in clients that usually filter out static bots.
\n * NoFall Logic: Calculates expected fall distance server-side rather than trusting the client’s ground state, fixing false flags on stairs
\n and ledges.
\n * Ping Scaling: Checks automatically adjust thresholds based on the player’s connection stability and server TPS.<\/p>\n
Requirements<\/p>\n
* Java 21 or newer.
\n * ProtocolLib (Required for packet interception).<\/p>\n
Roadmap to 1.0<\/p>\n
This project is in active development. Features listed below are planned milestones before the first Stable release.<\/p>\n
Alpha (Current State)
\n * Core combat and movement checks are functional.
\n * The “Shadow Player” verification entity is implemented.
\n * Basic statistical profiling is active.<\/p>\n
Beta (v0.5)
\n * False Positive Freeze: A testing phase focused entirely on tuning thresholds with high player counts.
\n * World Checks: Improved detection for Nuker and Scaffolding.<\/p>\n
Release Candidate (v0.9)
\n * API: Allowing other plugins to query a player’s trust score.
\n * Optimization: Threading improvements for high-population servers.<\/p>\n
Stable (v1.0)
\n * Full production release.
\n * Codebase freeze and long-term support.<\/p>\n
Disclaimer: As this is an Alpha release, it is intended for testing environments. While we have tested significantly against false
\n positives, edge cases may still exist. Please report issues on the tracker.<\/p>\n","protected":false},"excerpt":{"rendered":"
