# XeroAntiCheat
|
|
|
|
Lightweight, accurate anti-cheat for Paper 1.21.x
|
|
|
|
## Latest Updates (v1.1.1)
|
|
|
|
- **CriticalCheck**: Removed dead code — the "no-air crit" detection branch was logically unreachable because `isCritical=true` requires `!isOnGround`, making the subsequent `isOnGround` check always false. The check now only flags "crit while sprinting" (the only branch that could actually fire). Removed `allow_jump_crits` config key. (Future enhancement: Option B damage-ratio detection.)
|
|
- **InventoryMoveCheck**: Replaced `Math.sqrt()` with squared distance comparison (`distanceSquared > 0.01`), consistent with the ReachCheck optimisation.
|

|
|
## Latest Updates (v1.1.0)
|
|
|
|
- **ReachCheck**: Now measures distance to entity bounding box center instead of feet. Eliminates false negatives when attacking tall entities (horses, iron golems, withers). Also switched from `distance()` to `distanceSquared()` comparison, removing a `Math.sqrt()` from the hot path.
|
|
- **AutoClickerCheck**: `checkPattern()` rewritten with zero-allocation two-pass iterator approach. Previously allocated two `ArrayList` objects on every combat click.
|
|
- **TimerCheck**: Removed redundant blink detection from `check()` method. Blink detection is fully handled by the 5-tick scheduled task. `setLastMovePacketTime()` retained to feed the task.
|
|
- **KillAuraCheck**: Removed unused `EntityEffect` import.
