Inventory BlackList

Take absolute control of your inventory and eliminate entity lag with a lightweight, seamless, and highly optimized pickup filter.

Are you tired of filling your inventory with dirt, cobblestone, or rotten flesh while mining or mob farming? Wyvern Pickup Filter is the ultimate solution. Designed with both players and server owners in mind, it allows you to easily blacklist unwanted items while introducing a revolutionary anti-lag system for dropped entities.

Key Features Smart Item Blacklist: Easily search and add items to your personal blacklist through a beautiful, Vanilla-styled GUI.

Two Action Modes: Choose to simply "Leave on ground" (prevents you from picking the item up) or "Delete" (permanently destroys the item upon touching it).

Anti-Lag Super-Stacking: Server TPS dropping from too many items on the ground? When items are blocked and left on the ground, the mod automatically scans a 5-block radius and merges identical items into a single entity, completely ignoring the vanilla 64-item stack limit.

Seamless Integration: Access your filter menu via a fully customizable Hotkey (Default: B), or through an elegant, dynamic button attached to your survival inventory.

Highly Compatible: The inventory button automatically adapts its position, making it 100% compatible with inventory-modifying mods like REI or JEI.

Ultra-Optimized: Built from the ground up for maximum performance. Uses O(1) instantaneous memory checks to ensure zero lag, even on massive servers.

How to Use Press B (configurable in Options > Controls) or click the Hopper icon in your inventory to open the Filter Menu.

Use the search bar to find items.

Click on an item to add it to your Blacklist (a red "X" will appear).

Toggle between "Show All" and "My Blacklist" to easily manage your filtered items.

Toggle the Action Mode between "Delete" and "Leave on ground" depending on your needs.

Installation This mod is required on BOTH the Client and the Server.

Singleplayer: Just drop it in your mods folder.

Multiplayer: Must be installed on the server (to handle the anti-lag and entity manipulation) AND on the players' clients (to access the menu and configure their personal filters).
