AstraAc

AstraAC is a modern, lightweight anti-cheat for Minecraft servers, specifically designed for versions from 1.21 to 1.21.4. Its primary goal is to ensure gameplay integrity without placing excessive strain on the server.

Purpose and Character:

The character of AstraAC is defined by four key attributes:

Lightweight and Performant: Built as a single JAR file with no external dependencies. It runs stably on both standard Paper and the modern regional Folia servers, utilizing a dedicated task scheduler. Compiled on Java 21 with the Paper 1.21.x API, it ensures optimal performance on the latest versions.

Highly Configurable: Every detection module (check) can be individually enabled, disabled, and fine-tuned in the config.yml file. The system allows for precise management of detection thresholds, punishments, and violation reset intervals, as well as differentiation between Java and Bedrock players (via Geyser/Floodgate).

Heuristic-Based Effectiveness: It detects cheats by analyzing player movement (flight, illegal speed), combat (KillAura, Reach, AutoClicker), world interactions (fast breaking/placing), and packet manipulation. It includes mechanisms to prevent false positives during server lag, player teleports, or logins.

Deep Server Ecosystem Integration: It offers comprehensive tools for server administration, including in-game alerts, detailed file logging, and Discord webhook integration. It provides an API for developers, enabling integration with other plugins and the creation of custom solutions. It is also aware of popular plugins like ViaVersion, mcMMO, and VeinMiner.

In summary, AstraAC is much more than a simple blocklist. It's an intelligent system that strives to find a balance between effectively combating cheaters and maintaining a comfortable experience for legitimate players, all while minimizing its impact on server performance. It's designed for administrators who value full control and transparency in their anti-cheat solution.
