Item Loader

The Item Loader is a block added by Railcraft used to deposit items from an adjacent inventory into a minecart with an inventory. When the cart is full, or meets the requirements set in the GUI the block will emit a redstone signal. In the GUI there is a Filters section, a Buffer section, and a few buttons. The Filters section determines which items and how many are taken from the inventory. The Buffer section is the place to put items to be loaded. Any adjacent inventories will automatically be put here. There are different modes for the Item Loader to use, for the top button we have All, Transfer, Stock, and Excess. All will move all items. Transfer will move the exact items in the Filter. Stock will move items until the destination matches the filter. Excess will keep the items in the filter, and move the rest. For the bottom button we have Immediate, Complete, Manual, and Partial. Immediate will emit redstone if no items were moved. Complete will emit redstone when the move is complete. Manual will never emit redstone. Partial will emit redstone if no items were moved and cart is not empty.

Usage
Place the Item Loader directly next to the block you want to output items from, and directly above a track. Use Chest Carts to move the items from the Item Loader. Set the Filters, redstone control, and item movement control buttons to your preferred settings. It is recommended to use a Holding Track or a Boarding Track, because they will stop the cart when there is no redstone signal, and will force the cart to continue when there is a redstone signal.
