Yes, this block sucks.
A vacuumulator (also known as an item collector) is a device that collects nearby dropped items.
When placed, a vacuumulator faces the player. It can face any of the four cardinal directions, and can be rotated using a wrench.
A vacuumulator collects dropped items in an 11x11x11 area. It attempts to collect items every 16 ticks (0.8 seconds), or directly after it is activated by a redstone signal.
Items can exit a vacuumulator through its sides. Every side of the device may be configured to be able to output items.
A vacuumulator can automatically transfer items out of any configured output sides. This is called auto-output, and occurs every 16 ticks (0.8 seconds), right before more items are collected. The device can automatically transfer up to 64 items at a time.
Which sides can output items and whether auto-output is enabled can be configured using the Configuration tab in the device’s GUI.
A vacuumulator can be configured to only collect items that match a given list of items. This can be done by using the placed vacuumulator while sneaking. It has various options that determine how this list is used to match items.
A vacuumulator may be configured to respond to redstone signals. It can be in one of three modes:
The current mode can be set using the Redstone Control tab in the device’s GUI.
A vacuumulator can have a signalum security lock installed to restrict who can access it.
A vacuumulator’s configuration can be saved on a redprint to be copied to other vacuumulators.
