What is it?
The Item Hopper is a new type of Storage Container that will instantly extract a stack of items from your player inventory every time you interact with it from the front. Interacting with any other part (includes front corners) will instead open the Hopper's storage/item filter UI.
This is a companion project to my Item Dispenser mod, which lets you quickly take full stacks of items from a variety of belt-fed Dispensers.
How do I use it?
The Item Hopper must first be unlocked by completing it's Tier 2 HUB milestone, then it can be found in the build gun menu under Organization > Storage. They are exactly as wide as a storage container, slightly shorter in height and significantly shorter in length. There is no clearance on the front of the Hopper, so you can clip it through walls.
To use your Item Hopper you must first set its item filter, which can be accessed by interacting with the sides of the machine. This is also how you access the Storage UI and other options, which will let you set the Hopper to extract multiple (up to 24) stacks at once, or set it to prefer taking the fullest vs emptiest stacks.
The display screen will show the icon of the first item filter rule.
The Item Hopper is paintable and stackable.
Multiplayer? Modded items?
Both are fully supported, or at least should be.
Item Hoppers support Ficsit Networks connections. A network adapter connection will apppear on the dispenser if you have that mod installed. Using that, you can configure the hopper and look at it's inventory from the network (use :getMembers() to see all available functions).
