Spartan AntiCheat & AntiExploit (Free with 5 or less players)

Core & Engine

• Compatibility: Full support verified for 1.21, 26.1, and 26.2.
• Block Data: Integrated collision mapping for all new block types.
• Violation Engine: VL points now decay naturally across all checks to stop infinite alert stacking and console spam from regular server latency.

Combat

• NoSwing: Stripped out the 1-second throttle and 1.0f cooldown requirements to catch aggressive 15+ CPS KillAura modules. Added a 150ms temporal buffer to absorb out-of-order packet batching without false flagging.
• Reach: Scaled reach limits dynamically based on attacker momentum to safely allow legitimate high-speed sprint-combos.
• KillAura: Added a pipeline cutoff to prevent false aimbot bans when players are fighting inside cobwebs (compensating for the lack of WASD movement).
• Criticals: Blocked "Zero-Y" hover spoofs and micro-jump offsets (e.g., 0.0625).
• Velocity: Blocked "Reduce" hacks via yield percentage math and fixed Ping Spoof bypasses by decoupling knockback from network transaction stalling.
• FastClicks: Injected RNG pattern analysis to catch randomized macros and Modal Duplication flaws.
• FastBow: Tightened draw-time thresholds to 850ms to shut down server-side "Insta-Bow" exploits.

Inventory & Consumables

• ImpossibleInventory: Replaced broken death-tracking with Inhuman Damage-Reaction tracking to catch real Auto-Totem hacks. Fixed the InvMove walking bypass by tracking horizontal movement, and added buffers for mid-air inventory clutches and portal-edge desyncs.
• InventoryClicks: Removed the ItemMeta requirement to catch Auto-Armor/Auto-Pot using generic items. Tracked keyboard actions to catch hotkey macros, fixed exact-match buffer bypasses, and added amplitude caps to stop 0ms lag-spike bans.
• FastEat: Hooked PlayerItemConsumeEvent to stop bypasses when eating Gapples at 20/20 hunger. Added offhand scanning for potions and kelp.
• FastHeal: Rebuilt Regen math to use exact vanilla bitshifting to stop bypasses and stabilized 1.9+ saturation jitter.

Movement

• IMFoodSprint: Added a 1000ms latency grace period for server-client food desyncs, and built a VL accumulator to mathematically catch sprint "pulse-toggling" cheats. Explicitly exempted Elytras and Vehicles.
• Elytra: Switched deployment logic to track vertical acceleration rather than raw Y-speed (allows quick-deploy jumps). Sealed the floating-point "Energy" bypass used for infinite level-flight.
• Vehicles: Isolated boat/minecart max speeds from player modifiers (Speed potions/Soul Speed). Added exponential limit scaling for Blue/Packed Ice boat highways.
• Fluid Dynamics: Overhauled fluid drag to accurately support 1.13+ sprint-swimming, Depth Strider, and lava wading.
• Gravity: Decoupled fall-start predictions to stop false desync flags when crossing chunk boundaries.
• Custom Mounts: Expanded teleport thresholds to absorb extreme momentum shifts from non-vanilla vehicle systems.

World & Building

• FastBreak: Closed the 0ms Insta-Break loophole and completely eliminated the 400% speed exploit by moving to a strict 80% vanilla limit with a flat latency buffer.
• BlockReach: Transitioned to "Eye-to-Center" coordinate math for perfect accuracy, fixing bypasses when mining straight down and false positives when bridging diagonally.
• FastPlace: Fixed division-by-zero vulnerabilities during TPS drops and expanded the detection net to catch "soft" 190ms auto-builders.
• Interactions: Fixed the "floor-staring" bypass for block interaction events.
