Payload Unloader

Payload Unloader is a block that controls when and how a carried payload is ejected from its internal payload buffer. It does not begin outputting the contained payload on the side it faces until the payload has been fully cleared of both item and liquid components. This behavior guarantees that no partial payloads are emitted from the facing side while any items or liquids remain inside the buffer.

The block accepts payload inputs from any side of the structure, and this includes the side that is designated as its output face. Because inputs are accepted from all directions, the block can receive payloads even while its facing side is configured as the discharge side; however, actual discharge through that facing side will be withheld until the payload buffer contains no items or liquids.

Key properties and practical implications:

• The block withholds emission on its facing side until the payload buffer is completely empty of items and liquids. This prevents partial transfers where only part of a mixed payload (items or liquids) would be left behind or emitted prematurely.
• It can accept incoming payloads from any side, including the facing output side. This allows flexible placement in a network of conveyors or other payload sources without requiring a separate input-only orientation.

Practical usage notes:

• Use this block when you need atomic unloading behavior so that a unit or transport does not leave with residual items or fluids still inside the payload. Its withholding behavior enforces complete emptying before output occurs on the face side.
• The ability to accept inputs from every side simplifies layout constraints: you can feed payloads from multiple directions without reorienting the block. Be mindful that although inputs may arrive on the output-facing side, they will not be immediately emitted from that face until both item and liquid contents are cleared.
