# AstroX AntiCheat<\/p>\n
AstroX AntiCheat is a high\u2011performance **Geyser Extension** that inspects **Bedrock client packets** before they are translated to Java. It targets common Bedrock cheat behaviors (speed, fly, reach, and bad\u2011packet abuse) while keeping Netty I\/O threads non\u2011blocking for large servers.<\/p>\n
## Highlights
\n– **Packet\u2011level detection** for Bedrock clients (pre\u2011translation)
\n– **Movement prediction engine** tuned to Bedrock physics
\n– **Reach heuristics** with ray + dot checks and Bedrock hitbox leniency
\n– **Bad packet detection** (impossible sequences, spam bursts)
\n– **Statistical buffers (z\u2011score)** to reduce false positives from jitter
\n– **Async, striped execution** with object pooling for low GC pressure<\/p>\n
## Requirements
\n– Java 17+
\n– Geyser API **2.9.2\u2011SNAPSHOT**
\n– Geyser core version aligned with the API snapshot<\/p>\n
## Installation
\n1. download the JAR.
\n2. Drop it into your Geyser `extensions\/` folder.
\n3. Restart or reload Geyser.<\/p>\n
## Configuration
\nEdit `config.yml` in the extension\u2019s data folder to:
\n– enable\/disable checks
\n– adjust thresholds and buffer behavior
\n– tune sensitivity to your server\u2019s latency profile<\/p>\n
## Notes
\nAstroX AntiCheat uses internal Geyser classes for packet access. Keep Geyser core and API versions in sync for compatibility.<\/p>\n","protected":false},"excerpt":{"rendered":"
