GolfIV

GolfIV is a powerful protection tool for Fabric Minecraft servers, designed to prevent various types of exploitation and cheating. All mod features can be configured through the config/GolfIV_config.json configuration file.

Inventory Protection

• Inventory action checking - blocks the ability to attack or use chat with open interface
• Survival item cleanup - removes incompatible enchantments, resets stack sizes and other parameters
• Banned items - determines which items should be removed when clicked
• NBT tag removal - completely clears NBT data in creative mode while preserving block picking capability

Packet Security

• Teleport coordinate hiding - removes coordinate data from player teleportation packets
• Entity health hiding - removes health information from transmitted data
• Equipment concealment - prevents viewing of enchantments, durability and stack size by opponents with cheating clients
• Sound exploit protection - substitutes coordinates in sound events, hindering player location detection
• Portal verification - detects impossible actions in portals (chat, inventory management)
• Kick prevention - prevents banning through books and other inventory overflow kick methods

Movement Control

• Ground position verification - ignores onGround status from movement packets and uses own calculations

Duplication Prevention

• Save limitation - ignores data exceeding Java DataOutput limit, preventing save errors
• Gravity block protection - blocks duplication of falling blocks
• Post-death duplication protection - prevents inventory copying when dying after disconnection

Combat System

• Wall-hit prevention - blocks the ability to hit entities through walls
• Hit distance checking - prevents attacks from excessively long distances
