MultiLib

Actively developed – currently early stages, expect bugs

A library mod for defining and detecting multiblock structures, built around the MultiLib and its MultiblockBuilder.

What it does

• MultiLib.define(...) – start a new multiblock definition, identified by a ResourceLocation.
• MultiblockBuilder – fluent builder for layers, symbols, rotation rules, formation mode and callbacks.
• BlockIngredient – matches a pattern symbol against a block, tag, block state, or predicate.
• Flexible matching – shaped, shapeless and procedural (with PatternProvider).
• Persistent tracking of formed structures across the world and callbacks for simpler logics.
• Ghost-overlay preview and auto-place, to help building a multiblock.
• Structures can also be defined data-driven via JSON/datapacks, not just in code.

See the wiki for the full API reference, the Getting Started guide and example.
