How to Collect, Filter, and Void Items Automatically on Moving Contraptions

Mining drills, harvesters, and rail-based machines generate large amounts of loose drops and unwanted clutter. By mounting an upgraded Sophisticated Backpack onto your Create contraption, you can handle item collection and trash disposal directly from the moving machine.

Setting Up Collection Upgrades

1. Place your backpack down and open the Backpack Settings interface.

2. Insert a Pickup or Magnet upgrade into the upgrade slots. Because location-dependent upgrades track the contraption's live position in the world, the Magnet upgrade pulls in nearby loose items along the path as your build moves.

3. Ensure there are open inventory slots inside the backpack to receive incoming drops.

Managing Overflow and Sorting

1. Install a Filter upgrade to control which items are allowed to enter or leave the backpack's storage while the contraption operates.

2. Add a Void upgrade and configure its settings to automatically delete excess cobblestone, dirt, or unwanted byproducts before the inventory fills up.

3. Assemble your Create contraption or minecart contraption and start it moving. All four upgrades—Pickup, Magnet, Filter, and Void—remain active in real time as the machine travels.
