AntiPieChart

Description
AntiPieChart is a lightweight security plugin that prevents players from abusing Minecraft’s built-in debug pie chart (Shift + F3) or ESP hacks to locate hidden bases, farms, or villagers.

Normally, the pie chart exposes block entities (chests, ender chests, barrels, furnaces, etc.) and entities (villagers, iron golems, armor stands, pets) even if they’re underground or hidden behind walls. Hack clients use the same information for ESP overlays.

AntiPieChart fixes this by intercepting packets with ProtocolLib and only sending block/entity data when the player should know about it.

• Hide Block Entities → Ender chests, barrels, furnaces, shulkers, etc. are replaced with harmless placeholder blocks until revealed.
  
  
• Hide Entities → Villagers, iron golems, armor stands, and more are hidden until visible.
  
  
• LOS + Distance Modes → Reveal when in line-of-sight, or always reveal if very close.
  
  
• ️ Anti-ESP → Hack clients can’t lock onto entities that were never sent.
  
  
• ️ Configurable & Reloadable → Control worlds, placeholders, reveal distances, permissions, and more.
  
  
• Safe → No dupes, no glitches, no gameplay exploits.

Requirements

• Minecraft 1.20 – 1.21 (tested on Purpur 1.21.8)
  
  
• Java 21 or higher
  
  
• ProtocolLib (required dependency)

Commands

• /piecloak reload – Reload the plugin configuration.

Permissions

• antipiechart.bypass – Exempts a player from masking (useful for staff/admins).

Usage

1. Install ProtocolLib.
   
   
2. Drop AntiPieChart.jar into /plugins/.
   
   
3. Restart the server.
   
   
4. Edit plugins/AntiPieChart/config.yml to adjust settings.
   
   
5. Run /piecloak reload to apply changes.

Once installed, the pie chart will no longer leak hidden bases. Players can only see block entities and entities when they are close enough or actually in line-of-sight.
