Woppers for Java [Filtering Hoppers]

Vanilla hoppers are the backbone of every Minecraft storage system, but they lack the precision that technical players crave. Woppers for Java [Filtering Hoppers] changes that completely. This server-side plugin transforms ordinary hoppers into smart, configurable sorting machines without adding a single new block, GUI, or command. Just rename a hopper in an anvil, place it down, and watch your item networks become instantly more intelligent.

Why Woppers for Java [Filtering Hoppers] Stands Out

Most hopper filtering solutions demand complex redstone circuits, extra mods, or clunky interfaces. Woppers takes a radically simple approach: the hopper’s name becomes its configuration. This means zero learning curve for anyone who has ever used an anvil. The plugin is built for survival servers, storage rooms, item sorters, and large-scale automation projects where reliability and performance matter.

Core Features at a Glance

• Item Filtering – Restrict a hopper to transfer only specific items. Rename it to IRON_INGOT, DIAMOND, or NETHERITE_INGOT and it will ignore everything else.
• Custom Hopper Speeds – Control transfer rate directly from the name. Use */4 for very fast movement, */8 for vanilla-like speed, or */20 for a slow, deliberate flow.
• Combined Rules – Merge filtering and speed in one hopper. A name like IRON_INGOT/4 moves only iron ingots at speed 4, while COBBLESTONE/16 handles cobblestone at a moderate pace.
• NBT Filtering (Beta) – Experimental support for filtering by item NBT data, perfect for custom items or modded content.
• Vanilla Friendly Fallback – Invalid or unrecognized hopper names automatically revert to standard vanilla behavior. No item loss, no world conversion, and no risk to existing builds.

How It Works: Rename, Place, Automate

The magic of Woppers for Java [Filtering Hoppers] for Minecraft lies in its anvil-based configuration. There are no commands to memorize and no extra blocks to craft. Simply rename a hopper in an anvil using one of the supported patterns, then place it in your world. The plugin reads the hopper’s name and applies the corresponding filter and speed rules instantly. This design keeps your gameplay immersive and your server lightweight.

Practical Examples

Here are a few hopper names and what they achieve:

• IRON_INGOT – Transfers only iron ingots.
• DIAMOND – Transfers only diamonds.
• */4 – Transfers all items at speed 4 (very fast).
• */16 – Transfers all items at speed 16 (slower).
• IRON_INGOT/4 – Iron ingots only, at speed 4.
• COBBLESTONE/20 – Cobblestone only, at speed 20.

Compatibility and Supported Versions

Woppers is designed for modern Paper servers and runs on Minecraft 26.1.2 with Java 25. It is fully server-side, meaning no client mods are required. Bedrock players can join and benefit from every feature thanks to seamless Geyser and Floodgate support. The plugin works out of the box on existing worlds without any conversion steps, preserving all your current hopper setups.

How to Install Woppers for Java [Filtering Hoppers]

Getting started is straightforward. First, download Woppers for Java [Filtering Hoppers] from the official release page. Place the downloaded .jar file into your server’s plugins folder, then start or restart the server. Once the server is running, grab an anvil, rename a hopper with your desired rule, and place it. That is all there is to it. For those who manage multiple add-ons, the foxygame.net launcher provides a convenient add-on catalog where you can install Woppers for Java [Filtering Hoppers] with a single click and keep it automatically updated across version changes.

Performance and Best Practices

Woppers is built to be lightweight, but transfer speed settings can influence server load on massive hopper networks. The recommended speed ranges are:

• 2–4 – Very fast, ideal for high-throughput farms.
• 8 – Vanilla-like speed, safe for most systems.
• 10–20 – Moderate, good for balanced sorting.
• 20+ – Slow, reduces tick impact on huge arrays.

Using extremely low values (like */1) on hundreds of hoppers may increase server tick usage, so test gradually and monitor performance.

Why Technical Players Love Woppers

Storage rooms become cleaner, item sorters require zero redstone, and large farms can move resources at exactly the pace you need. Because the plugin extends vanilla hoppers rather than replacing them, you keep full compatibility with existing redstone contraptions. The absence of GUIs and commands means you stay focused on building, not configuring interfaces.

Frequently Asked Questions

Does Woppers require a client mod?

No. Everything runs on the server side. Players using vanilla clients, Bedrock, or any modded client will experience the same filtering behavior.

Does it work with Geyser and Floodgate?

Yes. Bedrock players connected through Geyser can use renamed hoppers exactly like Java players.

Will it break my existing world?

No. Existing hoppers remain untouched. Only hoppers you rename and place after installation will adopt the new rules.

Is NBT filtering stable?

NBT filtering is currently in beta. While functional, some edge cases with custom items or third-party plugins may occur. Report any unexpected behavior to the author.
