Sticky Hopper

Sticky Hopper keeps a single item in each inventory slot instead of emptying itself. Comparators read its content as one copy per slot, so an item counted in a second slot shows as 2 out of its maximum stack size, and a single item held in other slots is still ignored. Items that cannot stack never register on a comparator, since each one takes its own slot. The block is based on an original prototype by Aurelien Sama, coded by ShoukaSeikyo, and a simple, small, sliceable redstone-less filter suits it.

Transfer speed differs from a normal hopper. A normal hopper moves items every 8 game ticks, while a Sticky Hopper only passes an item on once a second copy of the same item arrives, so it looks slower at first. A Honey Bottle placed on top of a normal hopper gives an empty Glass Bottle back, and a Snowball placed on top of a Sticky Hopper cleans up the honey. The mod works without conflict with Speedy Hopper, which means Speedy Hopper is not compatible with it. Sticky Hopper is a client and server mod, so the server and every player need it, and the author also publishes a version for a single side. Fast Sticky Hopper can be crafted as a separate block.
