InPost (create add-on)

Items can be transported instantly over long distances by placing an InPost block and entering a target location. The sender sets the destination with three coordinate fields for x, y and z, plus a slot in the middle of the screen that holds the item to send. Storage items such as backpacks and Create packages can be sent this way, and the author notes that lost items are a known issue to watch for. Five slots at the bottom of the screen hold the items received from others.

Automation is handled by InPost Calibrators, added in version 1.2.0. A calibrator is crafted from a chain with gold in place of diagonal pieces, and it reads data once powered by redstone. Right-clicking a calibrator sets a numeric value up to 128000, including negative numbers. The block is crafted from a surrounding chest with gold ingots, and a shift right-click with a Create packager completes the recipe.

InPost requires Create version 6.0.0 or higher. Without it, the InPost block is removed when the mod is loaded. The mod is published for Forge and NeoForge and runs on client and server, so both the server and every player need it. It is released under the MIT License and is not open source.
