Moog's Structure Lib (moogs_structures)

Added

• Structure processors:
  • pillar_processor - extends a pillar up or down from a trigger block until it reaches solid ground, with an optional altitude-aware block-state randomizer. Recognises legacy vanilla block ids (e.g. minecraft:chain from before the 1.21.9 rename) and rewrites them to their renamed modern equivalents so older authored structures keep generating correctly.
  • spawner_randomizing_processor - sets a mob spawner's mob from an inline weighted entity list (no external dependency). Each weighted entry may carry an optional nbt field so spawners can ship pre-equipped or otherwise pre-configured mobs without an extra processor.
  • trial_spawner_randomizing_processor - writes a chosen trial-spawner configuration into placed trial spawners, with an optional ominous variant. Uses inline configs on MC 1.21 - 1.21.4 and references the vanilla minecraft:trial_spawner registry on 1.21.5+.
  • vault_randomizing_processor - assigns a loot table and key item to a placed vault, automatically picking the ominous variant for blocks with the ominous blockstate set.
  • equip_armor_stand_processor - equips armor stands from a weighted-random list of armor sets, with per-item enchantments and trims expressed in the vanilla item-component format.
  • close_off_fluid_sources_processor, remove_floating_blocks_processor, random_replace_with_properties_processor, super_gravity_processor, flood_with_water_processor.
• Per-piece spawn counts (data/<namespace>/msl_pieces_spawn_counts/ and ..._additions/): a datapack-driven cap on how many times each jigsaw piece may appear in a generated structure, so rare pieces stay rare without rebuilding the pool. The _additions variant lets downstream datapacks extend or override another mod's counts without forking the source file.
• Entity processor framework (StructureEntityProcessor): lets processors modify or equip entities as a structure is placed. On Fabric a mixin runs the entity processors during StructureTemplate.placeEntities (which vanilla never invokes the entity hook for); Forge/NeoForge use their native entity processing.
• Enhanced terrain adaptation (beardifier): carves or buries terrain around pieces, with a configurable vertical band to confine carving to matching-height rows.
• Basalt & delta suppression: prevents basalt columns and basalt deltas from generating within structure piece bounds (structure tags no_basalt, no_delta).
• Nether jigsaw structures: raised size cap to 128 pieces, added a FIXED_HEIGHT land search direction for structures that must place at a specific Y, and stricter y_allowance enforcement on final placement.
• Debug command: /moogs_structures debug keepjigsaws on|off|status keeps jigsaw blocks in placed structures so their name/target/pool can be inspected in-world.

Fixed

• dependent mods (e.g. Moog's Nether Structures) failing to recognise this build as version 3.0.0.
• structures with enchanted armor on armor stands failing to load.
