<h1><img src="https://i.imgur.com/mBOLXDf.png" alt="Magnet Hopper" width="1280" height="550" /></h1> <h1>Magnet Hopper</h1> <p>A hopper variant that pulls dropped items in a 3D radius before depositing them into the container below. Solves the universal "items despawn around my mob farm" pain in one dedicated block.</p> <h2>Features</h2> <ul> <li><strong>Magnet pull</strong> &mdash; ItemEntities in the tier's 3D radius get vacuumed into the internal 5-slot storage and flow down into the container below.</li> <li><strong>Vanilla hopper behavior always active</strong> &mdash; strict superset of a regular hopper: pulls from any container above, pushes to any container below at the standard 8-tick cadence.</li> <li><strong>Magnet on/off toggle</strong> &mdash; UI button to disable just the magnet pull (block keeps acting as a normal hopper).</li> <li><strong>5-slot whitelist/blacklist filter</strong> &mdash; click a filter slot with an item to ghost-set (the item isn't consumed); empty-hand click to clear; toggle whitelist/blacklist in the UI.</li> <li><strong>Redstone-disable</strong> &mdash; applying a redstone signal pauses everything (matches vanilla hopper convention).</li> <li><strong>Placement preview</strong> &mdash; hold a magnet hopper in either hand and the affected radius draws as a cyan-mint wireframe over your cursor target, with a warm-green surface contour that follows terrain so the floor coverage is always legible.</li> <li><strong>Pipe compatibility</strong> &mdash; exposes the 5-slot storage via Fabric <code>ItemStorage.SIDED</code> and the NeoForge item-handler capability. Filter slots are config, not exposed.</li> </ul> <h2>Compatibility</h2> <ul> <li><strong>Minecraft</strong>: 26.1.x</li> <li><strong>Fabric</strong>: Loader 0.18.4+ with Fabric API</li> <li><strong>NeoForge</strong>: 26.1+</li> <li><strong>Java</strong>: 25</li> </ul> <h2>Known limitations</h2> <ul> <li>Items in internal storage spill when the block is broken (the drops are still pickup-able). NBT carry-over planned for v0.2.</li> <li>Filter configuration is lost on break. Planned for v0.2.</li> <li>All magnet hoppers face down only; side-facing variant planned later.</li> </ul> <h2>License</h2> <p>CC0-1.0 (public domain).
