## v0.3.1-alpha ### Added - **Configuration GUI** — `/hxwi1 config` opens a dual-panel GUI - Left panel automatically scans NBT files - Right panel scrollable form for editing all fields - Auto‑serializes to JSON on save - **Config reload** — `/hxwi1 reload` hot‑reloads rules without restart - **Flatten ground** — `flatten_ground` field: fills gaps under the structure with a specified block before placement - **Ground block** — `ground_block` field: customisable block for flattening (default `minecraft:dirt`) - **Extra block removal** — `clear_blocks` field: manually specify blocks to remove (solves trees from mods that don’t register standard tags) - **Biome tag support** — `biomes` field supports tags like `#minecraft:is_forest`, can be mixed with exact IDs - **Command** — `/hxwi1 biomeinfo` shows current biome and list of NBT files that can generate there - **Command** — `/hxwi1 spawn <file>` manually spawns a structure at your current position (Tab‑completion, supports subfolders) - **NBT subfolders** — recursively scans all `.nbt` files inside `structures/` - **Entity placement** — entities inside the template (villagers, armour stands, etc.) are spawned with the structure - **Rotation offset** — `rotation_offset` corrects orientation errors from saved NBT files - **README** — tutorial file supports hot‑reload, no game restart required - **Language support** — UI and readme tutorial auto‑switch between Chinese and English; other languages are outdated but still usable, planned to be fully updated in the future - **Command toggle** — `mod_settings.json` allows disabling all `/hxwi1` debug commands - **Auto‑backup** — automatically backs up config when saving to prevent accidental deletion (backup count configurable via `max_backups`) ### Fixes - Flowers and replaceable plants are now treated as replaceable by default, preventing structures from floating - `place_on_water` renamed to `Snap to Water Surface` - Fixed border rendering on the right panel of ConfigScreen; scissor cropping prevents control overflow ### Compatibility testing - Verified to run normally in Better MC v58 (BMC4) and All the Mods 10 - 7.0, with negligible performance impact - Semi‑compatible with Dynamic Trees mod; may require extra configuration in `clear_blocks` to fully remove Dynamic Trees blocks ### New configuration options - `commands_enabled` — modpack/server owners can disable all `/hxwi1` commands - `max_backups` — number of backups to keep (0–20, default 2) - `enabled` — each rule can be individually toggled on/off - `min_chunk_distance` — minimum chunk distance between same‑type structures (default 5 chunks) ### Known issues - Underground generation does not have collision detection enabled and may overlap with other mods’ dungeons. Mitigate by adjusting Y range or increasing `min_chunk_distance`.
