keranantixray

KeranAntiXray is a high-performance Anti-Xray and Anti-Freecam plugin designed specifically for Paper, Folia, and Canvas 1.21+. It provides advanced Nether Roof protection to prevent players from using Freecam to inspect areas above or below the bedrock layer.

Core Features

World-Based Anti-Xray - Separate configuration for: - Overworld - Nether - Hide blocks below a configurable Y-level - Optimized for high-performance servers

Nether Roof Protection (Anti-Freecam) When a player is below the bedrock roof: - All blocks above the configured roof Y-level are sent as air - Freecam cannot see bases or builds on the Nether roof when the player is below the bedrock roof - Full chunk data is restored automatically - No interference with legitimate roof gameplay

Compatibility - ✅ Paper 1.21+ - ✅ Folia - ✅ Canvas - ✅ Java 21+ - ❌ No ProtocolLib required - ❌ No external AntiCheat required

Configuration Example

```yaml antixray: enabled: true worlds: world: hide-below-y: 16 world_nether: anti-freecam: enabled: true roof-y: 128 cloak-below-roof-when-on-roof: true hide-roof-until-player-above-roof: true ```

Configuration Explanation - `roof-y` → Height of the Nether bedrock roof - `hide-roof-until-player-above-roof` → Sends AIR above roof until player climbs up - `cloak-below-roof-when-on-roof` → Disables restriction once player is above roof

Designed For - Survival Servers - SMP - Anarchy - Skyblock with Nether - Folia / Canvas performance servers

Prevents: - Freecam roof base scouting - Xray under bedrock - Unauthorized structure inspection

Notes - Operates at chunk data level (server-side) - Does not modify actual blocks on the server - Does not interfere with entities - Fully region-thread safe for Folia
