Masterful Machinery Upgraded

[1.21.1-0.11.0] - 2026-10-09

Added

• Single-block machines ("type": "mm:single"). A whole machine in one block, like a furnace, with no structure or ports. List what it holds under slots: item, fluid, energy and Mekanism chemical slots, each with the same options as a port of that type. Recipes use the controller id as their structureId. See single-block.md.
  • Its screen is built from the slots: energy on the outside, then tanks, then item slots around the progress bar. A button opens the controller screen for its name, redstone mode and the rest.
  • Pipes, hoppers and cables fill its inputs and take from its outputs, from any side.
  • From KubeJS, .type('mm:single') and .slot(id, type, input, config).
  • Each fluid stays in one tank of a fluid slot, so one fluid can not fill them all.
• fluids on fluid ports and slots limits them to certain fluids, as ids or tags ("fluids": ["minecraft:lava", "#c:oil"]). From KubeJS, .fluids(...).
• EMC ports show a bar on the controller screen, like energy.

Fixed

• A typo in a KubeJS port or controller script no longer crashes the game with Unknown port type 'null'. The KubeJS error that names the file and line is shown instead.
• Shift-clicking into a port no longer puts items into slots that do not take them.
