🔍 Fixes
🪧 ThruBlocksB -- Sign Hitbox False Positive

Improves consistency, reduces edge false positives, and aligns the checks more closely with real in-game combat behavior.

- Detects suspicious automated trap-placement behavior around players.\
- Optimized for low overhead and minimal risk of false positives.
⚙️ Config Additions

- New section in
config.ymlfor toggling and tuning AutoTrapA.\ - ConfigManager updated to load & manage all new values.\

📌 Summary

DuckyAC 1.1.2
release21 сентября 2025 г.🛠️ DuckyAC v1.1.2 – Edge & Water Grace Update
In v1.1.2, we’re addressing false positives around block edges, water transitions, and Elytra flight, while also simplifying reach detection for more predictable results.
🔍 Fixes
🪨 GroundSpoofA Edge Detection
- Fixed false alerts when players were standing on the edge of a block.
- The check now probes multiple points (center, axis, corners) around the player’s feet before flagging.
🌊 Water Transition Handling
- Fixed false alerts when leaving water.
- Added a 300 ms grace window after exiting water where checks are skipped.
🪂 Elytra Grace
- Fixed false alerts when toggling Elytra flight.
- Checks are skipped while gliding and ±300 ms around start/stop.
📏 ReachA Stability
- Removed reliance on per-player attributes for reach distance (unreliable across versions).
- Always falls back to the configured
base-range+ tolerance.
✍️ Improvements
- Clearer debug messages with explicit reasons why a check was skipped (e.g., teleport, damage, velocity, Elytra, water).
- More predictable ping compensation logic for ReachA and FlyA.
- Reduced risk of combat/movement disruption caused by legitimate transitions.
⚠️ Config Changes
🔧 No need to reset your entire
config.yml.
Just ensure the following lines are present (new keys have safe defaults if missing):
reach-a:
base-range: 5.0
📌 Summary
This update focuses on reducing false positives and giving server owners more control over movement tolerance. Default values are tuned for stability, but can be customized in config.yml if needed.

- Integrated Wind Charge awareness into both AirJumpA and FlyA checks for more accurate validation.
✍️ Improvements

wind-charge-grace-ms: 900
These options enable correct detection while respecting Wind Charge's intended behavior.
