zAntiFreeCam

Overview

zAntiFreeCam is a server-side protection plugin designed to control underground visibility against Freecam and similar client-side camera techniques.

Instead of modifying your actual world, zAntiFreeCam processes protected chunk information before it reaches the player.

Your world remains untouched.

The protection operates on what the client is allowed to receive, keeping your actual terrain intact.

Core Protection

Underground Visibility Protection

Prevent surface players from receiving protected underground terrain information below your configured Y level.

Chunk Data Masking

Protected underground sections can be represented using a configurable mask block before the information reaches the client.

No World Modification

zAntiFreeCam does not permanently replace, destroy, or modify your actual terrain.

Underground Entity Protection

Underground entities can be filtered from players who should not have access to protected areas.

Block Entity Filtering

Protected underground block entities can be filtered from outgoing chunk information.

Smart Visibility System

zAntiFreeCam handles visibility based on the player's position and configured protection thresholds.

Surface

Protected underground information remains hidden.

Underground

Players who legitimately enter the protected area can receive the real terrain according to the configured reveal threshold.

Return to Surface

Protection can be applied again when the player returns above the protected area.

Configurable Protection

Every server has different terrain, gameplay, and protection requirements.

Configure the protection depth and masking behavior directly from the plugin configuration.

Example configuration:

Hide below: Y 16
Reveal below: Y 15
Mask block: Stone

Fully configurable to match your server.

Performance Controls

Protection should not become another source of server lag.

zAntiFreeCam provides configurable processing controls for:

• Chunk update limits
• Chunk refresh timing
• Dirty chunk limits
• Player state checks
• Debug processing

Administrators can tune the protection workload for their own server environment.

Packet-Level Protection

zAntiFreeCam focuses on outgoing chunk information rather than physically changing the world.

This creates a separate protection layer between the server's actual terrain and the information received by the client.

Real terrain stays real. Protected data stays protected.

Bypass System

Trusted staff members can bypass protection using permissions.

zantifreecam.bypass

Additional administrative permissions are available for plugin management, reload operations, status checks, and controlled bypass management.
