Lightning Grim Anticheat: High-Performance Anti-Cheating Solution

Lightning Grim Anticheat stands as a highly optimized fork of the well-regarded GrimAC, purpose-built to tackle the persistent challenge of cheating on Minecraft servers. This plugin addresses a critical need for server administrators by implementing substantial performance improvements alongside significantly superior checks for player reach, block placement, and various interaction exploits. It effectively counters a wide array of illicit client modifications that provide unfair advantages, ensuring a fairer gameplay environment for all.

This anticheat is designed for server owners and administrators who prioritize both high accuracy and minimal performance impact. With precise 3.0005 reach detection and an impressive 99.999% anti-knockback effectiveness, Lightning Grim Anticheat helps maintain competitive integrity. Its optimized codebase means that advanced cheat detection does not come at the cost of server stability or player experience, making it an excellent choice for any server seeking to deter rule-breakers.

• WallHit Detection: Actively checks for and prevents players from hitting entities through solid blocks or walls.
• EntityPierce Checks: Monitors and blocks attempts to attack entities that are obscured by other entities.
• Optimized Hitbox & Collision: Features refined hitbox and collision box calculations, coupled with optimized reach checks for greater accuracy.
• PacketOrder Analysis: Utilizes checks for unusual packet order, effectively patching various no-slow, auto-block, and other timing-based combat cheats.
• Inventory Interaction Checks: Prevents common inventory exploits, such as using crafting slots for extra storage or moving while an inventory interface is open.

Lightning Grim Anticheat supports a wide range of Minecraft server versions, specifically 1.8 through 1.21.5. Servers utilizing ViaVersion will find full compatibility for players connecting from 1.7 all the way up to 1.21.x, irrespective of the native server version. It's important to note that Geyser (Bedrock Edition) players are fully exempt from its checks to prevent false positives and ensure compatibility.
