GameFilter

GameFilter

Take full control of your server’s progression by banning specific items, blocks, entities, potion effects, and recipe outputs through a simple JSON config. GameFilter removes banned items from creative tabs, /give, inventories, and drops, blocks banned entities from spawning, strips banned ores from new world generation, and can run a slow one-time background scan to clean already-generated chunks from spawn outward.

How to Use

• Add IDs to banned_items in config/gamefilter.json using format modid:name
• Set initial_scan_complete to false to run the one-time background cleanup scan
• Restart the server to load config changes and begin scanning/removal
• Use item IDs (e.g. minecraft:diamond) to remove access from creative, give, drops, and inventories
• Use block IDs (e.g. minecraft:diamond_ore) to stop new generation and replace existing banned ore blocks during scan
• Use spawn egg/entity-related IDs to prevent natural spawns and command-based spawning
• Use effect IDs (e.g. minecraft:speed) to block /effect give and other effect applications

Requirements
