NoChance v1.4.5

New Systems

• Prediction engine that tracks movement and combat patterns for smarter detection
• Movement predictor with physics simulation (gravity, friction, input tolerance)
• Combat predictor that analyzes aim tracking and reaction times
• Cross-check correlation ties related violations together for higher confidence

Detection Improvements

• FastBreak now properly calculates break times for 40+ block types
• Fixed incorrect hardness values for blue ice, carpets, snow layers, grass
• Added pickaxe requirement checks for iron doors, hoppers, anvils, lanterns, etc.
• Sword break speed corrected for non-cobweb/bamboo blocks
• Mining fatigue now uses vanilla multiplicative formula instead of linear
• Nuker detection improved with proper instamine awareness
• Reach check entity size bonus rebalanced to prevent stacking
• KillAura cooldown and aim lock checks tuned to reduce false flags
• Velocity check no longer wrongly factors in Resistance potion
• Elytra fly and speed limits brought closer to vanilla values
• Timer detection tightened to catch 1.05x+ speed
• NoFall no longer misdetected as Blink
• Blocking while sprinting no longer flagged (valid in 1.9+)

False Positive Fixes

• Trust and suspicion scores now decay properly after clean play
• Break interval history clears when mining pattern changes
• Suspicious break ratio actually decays over time now
• Violation history expires after 2-3 minutes instead of lasting forever
• Suspicion levels can step down faster with clean play
• Cross-correlation multiplier capped to prevent instant-flags from borderline violations
• Bad packet checks no longer flag AFK or stationary players
• Blink detection won't trigger during chunk loading or while falling

Compatibility

• Bedrock players now exempted from combat, block, and inventory checks
• ViaVersion tolerance stored per player for older client support
• Floodgate UUID detection narrowed to avoid misclassifying Java players
• Ice blocks now recognized as pickaxe blocks for proper break time math
• Nether gold ore no longer requires iron+ pickaxe

Stability

• Fixed crash from null metadata in packet analyzer
• Thread safety improvements across PlayerData, ViolationQueue, and ScaffoldCheck
• Async check processor race condition fixed
• Player cleanup on quit now covers all subsystems
• Game mode and vehicle exit now properly reset check state

• Added aim assist detection
• Added ghost hand/invalid interaction detection
• Added protocol abuse detection
• Better movement alerts (now shows ground/air/strafe for speed, hover/vertical/glide for fly)
• Better scaffold alerts (bridge vs tower)
• Better noslow alerts (item/web/honey)
• Smarter false positive filtering with longer session tracking
• Improved pattern detection across all checks (Increased sampling sizes for better data collection)

Fixes

• Jesus check no longer false flags when bobbing at water surface
• ElytraFly won't flag during sharp turns or landing

Added

• Missing checks now in GUI (ElytraFly, NoSlow, GroundSpoof, BadPackets, BoatFly, Strider)
• Min/max validation for skill profile settings

Improved

• Faster detection on NoFall, Velocity, GroundSpoof
• Better inventory null handling
• Reorganized GUI menus

• Fixed compatibility for 1.20x-1.21.11
• Improved GroundSpoof false positives
• Improved FlyCheck
• Improved MovementChecks

Added

• Bedrock/Geyser player detection (auto-detects Floodgate players)
• Ping compensation system (adjusts thresholds for high latency players)
• /nc spectate <player> - invisible spectator mode with follow cam
• /nc freeze <player> - freeze suspected cheaters in place
• /nc verbose - see all check triggers in real-time
• /nc profile <player> - view detailed player stats and ping info
• Clickable alerts with hover details (click to teleport, freeze, or spectate)
• Frozen player disconnect warning for staff

Improved

• Tightened all detection thresholds for faster flagging
• Lowered reach limit to 3.15 (was 3.5, vanilla is 3.0)
• Reduced max CPS limits (killaura 15, autoclicker 16)
• Stricter angle detection for killaura (35° from 48°)
• Disabled trust score bonuses on fastbreak
• Lowered ping tolerance multiplier (1.4x max)
• Reduced grace period to 3 seconds
• Alerts now show [BE] tag for Bedrock players

Fixed

• sendActionBar compatibility for Spigot servers

Config

• Added bedrock: section for Geyser/Floodgate handling
• Added ping_compensation: section
• All thresholds reviewed and tightened
• Comments moved above settings for readability
