Hopper Ducts - Hopper channels, item filtering на версии [1.12.2] [1.7.10]

Hopper Ducts - a mod for Minecraft that adds new capabilities for working with hoppers. Now they can transfer items in any direction thanks to the introduction of special channels. Additionally, a new type of hopper appears - the Grated Hopper, which can filter items. What is the difference between a regular hopper and a channel? Firstly, channels allow items to be transferred to an inventory above them but cannot retrieve items from it. Channels have only one slot for items. Moreover, after installation, they can be rotated in the desired direction by simply hitting them with a stick. Channels automatically connect to adjacent hoppers or channels. Their small size makes it easier to access the blocks behind them. And what does the Grated Hopper do? It has an additional slot for filtering items. Only items that match this slot can enter the hopper from the top or side inventory. The Grated Hopper also only ejects items that match the filter. This allows you to insert any items into the Grated Hopper and direct them to the desired inventory, and then use a regular hopper or the Grated Hopper to extract items that do not match the filter.
