NormalAntiESP

What is NormalAntiESP?
NormalAntiESP is a lightweight security plugin designed to reduce the advantage of players using ESP, StorageESP, BlockESP, Xray, Freecam, SeedCracker-style tools, and other suspicious client-side cheats.
The plugin focuses on protecting hidden entities, valuable blocks, containers, underground areas, and sensitive debug-side information while giving staff clear alerts and investigation tools.
This is not a magic instant-ban system. Instead, it helps staff detect suspicious behavior, hide protected information from clients, and react quickly when a player looks suspicious.
Main Features

• AntiESP protection for hidden entities, mobs, players, containers, and valuable blocks.
• AntiXray underground protection to reduce the advantage of Xray and Freecam.
• StorageESP / BlockESP mitigation for protected containers and valuable blocks.
• Suspicious behavior scoring system for staff investigation.
• Admin alerts when a player may be using Xray, ESP, or suspicious wall interactions.
• Clickable alert messages so staff can instantly watch a suspect.
• Built-in staff watch/vanish mode for silent investigation.
• Admin GUI to view suspicious players and recent flags.
• F3 Privacy to hide or spoof the server brand shown in the F3 debug screen.
• AntiSeedCracker protection by randomizing hashed seed values in JoinGame/Respawn packets.
• PacketEvents support for stronger packet-level obfuscation.
• Folia-safe design using region-safe scheduling where needed.
• Vietnamese and English messages included.
• MiniMessage and hex color support for modern server messages.

Admin Alert for suspicious Xray / ESP behavior

Detection System
NormalAntiESP tracks suspicious actions and adds score based on different detection types.
Current detection types include:

• Aiming at hidden entities - detects when a player appears to look directly at an entity that should not be visible.
• Aiming at hidden blocks or containers - useful against StorageESP and BlockESP behavior.
• Attack packet toward hidden entity - detects attack packets against entities hidden from that player.
• Suspicious wall interaction - detects suspicious interactions near protected hidden targets.
• ESP/Xray-like behavior - helps staff identify suspicious patterns for further investigation.

When a player reaches the configured alert threshold, staff members with permission will receive a warning message.
Admin Tools
NormalAntiESP includes tools to help staff investigate suspicious players quickly.
Commands:
Aliases:
The alert message can be clicked to automatically run:
This teleports staff to the suspicious player and enables staff vanish, making investigations faster and cleaner.
AntiXray Protection
NormalAntiESP includes an AntiXray system focused on underground protection.
The void-underworld mode can mask underground blocks below a configured Y level. This helps reduce the usefulness of Xray and Freecam by preventing the client from receiving useful underground information in protected situations.
Main AntiXray features:

• Client-side underground masking.
• Configurable Y level.
• Safe underground mode.
• Configurable world blacklist.
• Packet obfuscation support.
• Water/lava masking option.
• Performance caps to avoid large spikes.

For classic ore obfuscation, it is still recommended to combine this plugin with Paper's built-in AntiXray engine.
AntiESP Block Protection
NormalAntiESP can protect containers and valuable blocks such as:

• Chests
• Trapped chests
• Barrels
• Shulker boxes
• Hoppers
• Furnaces
• Spawners
• Trial spawners
• Vaults
• Diamond ore
• Emerald ore
• Ancient debris
• Gold ore
• Lapis ore
• Redstone ore

Protected blocks can be masked as normal blocks depending on the world environment, such as stone, deepslate, netherrack, or end stone.
F3 Privacy
NormalAntiESP can hide the real server brand sent to the client.
Example:
This helps prevent players from easily seeing your backend platform through the F3 debug screen.
Note: XYZ in the F3 screen is a client-side HUD. The server cannot change only the XYZ line without actually teleporting the player.
AntiSeedCracker
NormalAntiESP can randomize the hashed seed value sent in JoinGame and Respawn packets.
Example:
This does not change your real world seed. It only changes what the client receives in supported packet data.
This feature is still in beta, so it may not work perfectly in every situation.
Permissions
Permission details:

• normalantiesp.admin - Access to admin commands and GUI.
• normalantiesp.alerts - Receive suspicious player alerts.

Important Notes

• This plugin is designed for Paper/Folia 1.21.x.
• PacketEvents is optional, but strongly recommended.
• This plugin helps detect and reduce ESP/Xray advantages, but no anti-cheat can guarantee 100% protection against every client.
• For best ore protection, combine this plugin with Paper's built-in AntiXray.
• Always test configuration changes before using them on a live server.
