Dynamically scales reach and movement thresholds based on a player's real-time network latency. Misplace / Reach
Verus calculates the exact bounding box of the target entity at the precise mathematical time the player attacked them, factoring in latency (ping). If the distance between the player's eye location and the target's bounding box exceeds the legitimate limit (typically 3.0 blocks in survival mode), a Reach flag is raised. verus anticheat source code
Minecraft clients tell the server where they are moving using PacketPlayInFlying (and its sub-packets Position , Look , and PositionLook ). Verus builds a parallel simulation of the game physics on the server. Dynamically scales reach and movement thresholds based on
