BetterAnticheat

IMPORTANT: BEFORE INSTALLATION, PLEASE READ THE INFORMATION

Currently, BetterAnticheat is in an early development stage. Stability is not guaranteed, so use with caution.

BetterAnticheat is an auxiliary cheat protection system. This mod is not designed to detect standard violations like flight, speed movement, or extended reach. Its main purpose is to identify specific types of cheating that often go unnoticed by other anticheats. It is recommended to use BetterAnticheat alongside a primary protection system.

Key advantages of the system:

• Lag compensation — the system analyzes the client's perception of the world in real time
• Use of cookie packets — for compensation without interfering with Ping/Pong operation
• Dynamic command registration — command paths can be changed in real time, functions can be enabled and disabled
• Professional architecture — developed by experienced anticheat specialists
• Machine learning — assesses the trust level of players in combat

The system features minimal resource consumption, works on various platforms, and is compatible with other anticheats. Most checks use a zero-buffer system — if a check triggers, it means 100% cheating.
