Lightning Grim Anticheat Mod (26.2, 1.20.1) – Stop Cheaters Without Slowing

Lightning Grim Anticheat Mod improves the original GrimAC with better performance and stronger rules against cheaters. It patches ways players try to break the game, like hitting through walls or using extra inventory slots. The mod checks player movements and actions much faster so your server stays smooth. It guards your world against unfair play while letting honest players enjoy the game normally.

Features:

• Stops Wall Hits: Prevents players from attacking you or other mobs through solid blocks.
• Better Hitboxes: Calculates exact hit areas for every block so combat feels fair.
• Stops players from dealing damage through other mobs.
• Monitors inventory actions so nobody uses crafting slots as extra storage spaces.
• Replicates exact player movements to catch impossible walking, swimming, or flying.
• Runs heavy calculations in the background so your server does not slow down.
• Keeps a hidden copy of the world for every player to check if their actions make sense.
• Ignores bad internet connections so players do not get punished just for lagging.
• Understands different Minecraft versions so players on old updates still get checked correctly.

Movement Tracking:

• Tracks basic walking, swimming, and taking knockback accurately.
• Understands when players ride boats, pigs, or striders.
• Accounts for tiny block shape differences between old and new Minecraft updates.

Server Protection:

• Handles hundreds of players at the same time without causing slowdowns.
• Tracks items in player hands to stop ghost blocks during high lag.
• Waits for world changes to reach the player before making a decision on their movement.
