Frost AntiCheat

FrostAC is an SMP-focused anti-cheat designed to detect and prevent major combat and movement cheats while keeping false positives as low as possible.

🛡️ Detected & Blocked Cheats

• Fly / Flight — Detects abnormal airborne movement and impossible flight patterns.
• Speed — Detects movement faster than legitimate Minecraft limits.
• NoFall — Detects players bypassing or avoiding legitimate fall damage.
• KillAura — Detects impossible or suspicious automated attacks and abnormal combat behavior.

⚙️ Detection & Protection

• Repeated-strike detection before a player is punished.
• Fly: requires multiple confirmed flags.
• NoFall: requires multiple confirmed flags.
• KillAura: requires multiple confirmed flags.
• Speed: requires continuous abnormal movement.
• Confirmed cheaters are temporarily frozen instead of kicked.
• Players in the air are returned to their last solid ground before being frozen.
• Staff alerts can be enabled/disabled through configuration.
• Flags are logged for further investigation.

🚫 False-Positive Protection

FrostAC automatically ignores or accounts for legitimate situations involving:

• Ladders & Vines

• Slime & Honey Blocks
• Pistons
• Boats
• Elytra
• Riptide
• Knockback
• Explosions & Wind Charges
• Ender Pearls

FrostAC is designed specifically for SMP environments and focuses on detecting Fly, Speed, NoFall, and KillAura without interfering with normal Minecraft mechanics.
