Anticc 1.7 Guide

Study it to build better server-side movement checks. For server admins: Move to server-authoritative movement (e.g., GrimAC) – the only real solution. For players: Using it will eventually lead to a ban on any actively maintained server. Would you like a follow-up focusing on building a simple anti-anticheat plugin that detects the techniques Anticc 1.7 uses?

Anticc hooks Entity.getDistanceToEntity() → returns (realDistance - 0.5) for reach checks only. Visual position remains unchanged → player sees normal reach, server calculates fake distance. 3.2. Velocity Cancellation with Ratio Remainder If velocity is fully canceled ( motionY = 0 ), anti-cheats flag it. anticc 1.7

Maintain horizontal velocity ( motionX/Z ) but set vertical velocity to 0.0001 × random → looks like lag or slight knockback, but player takes no KB. 3.3. GCD (Greatest Common Divisor) Bypass Many anti-cheats track mouse movement consistency. Low GCD values indicate aimbot. Study it to build better server-side movement checks
