AstroxAC

AstroxAC is a high‑performance Geyser Extension that inspects Bedrock client packets before they are translated to Java. It targets common Bedrock cheat behaviors (speed, fly, reach, and bad‑packet abuse) while keeping Netty I/O threads non‑blocking for large servers.

Highlights

• Packet‑level detection for Bedrock clients (pre‑translation)
• Movement prediction engine tuned to Bedrock physics
• Reach heuristics with ray + dot checks and Bedrock hitbox leniency
• Bad packet detection (impossible sequences, spam bursts)
• Statistical buffers (z‑score) to reduce false positives from jitter
• Async, striped execution with object pooling for low GC pressure

Requirements

• Java 17+
• Geyser API 2.9.2‑SNAPSHOT
• Geyser core version aligned with the API snapshot

Installation

1. download the JAR.
2. Drop it into your Geyser extensions/ folder.
3. Restart or reload Geyser.

Configuration

Edit config.yml in the extension’s data folder to:

• enable/disable checks
• adjust thresholds and buffer behavior
• tune sensitivity to your server’s latency profile

Notes

AstroxAC uses internal Geyser classes for packet access. Keep Geyser core and API versions in sync for compatibility.
