Moog's Structure Lib (moogs_structures)

## [3.0.0] - 2026-06-02 Major feature release: a full structure-processor and pool-element toolkit, version-aware templates, terrain adaptation, and entity (armor stand) equipping. ### Added - **Version-aware pool element** (`moogs_structures:versioned_single_pool_element`): resolves a different structure template per Minecraft version, via a `locations` map of version ranges (e.g. `"1.21-1.21.4"`, `"1.21.5-26.1.2"`) with a fallback `location`. - **Mirroring pool element** (`moogs_structures:mirroring_single_pool_element`): a single pool element that can mirror its piece, with optional per-element enhanced terrain adaptation. - **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//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`). - **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. - Pillar structures that place chains failing to generate (chains were renamed to iron chains in Minecraft 1.21.9). ---
