About this Mod
Hxwi1Structures
NBT structure generation mod designed for modpack authors – visual config, high performance, ready to use.
📦 Overview
Tired of manually writing JSON to configure structure generation? Hxwi1Structures lets you manage all your NBT structure generation rules through a visual GUI. Drop your buildings, click a few times, and the world will generate them automatically.
| Feature | Description |
|---|---|
| 🎮 Visual Config | /hxwi1 config – dual-panel GUI, left pane auto‑scans NBT files, right pane editable fields |
| 🔄 Hot‑Reload | Configuration reloads automatically after saving – no need to restart |
| 🌍 Four Placement Modes | Snap to Surface, Snap to Water Surface, Dock Mode, Underwater Mode |
| 🎲 Fine‑Grained Control | Biomes (tag support), dimensions, Y range, chance, conflict ratio, min chunk distance, rotations, Y offset, etc. |
| 🪓 Extra Block Removal | clear_blocks – manually specify blocks to remove (solves compatibility with Dynamic Trees and similar mods) |
| ⛏️ Flatten Ground | flatten_ground + ground_block – automatically fills gaps under the structure |
| 💬 Debug Commands | /hxwi1 biomeinfo – shows current biome and spawnable structures, /hxwi1 spawn for manual testing |
| ⚡ High Performance | Chunk post‑processing + tick throttling + LRU cache, negligible TPS impact |
| 🔌 Excellent Compatibility | No Mixin – works with major terrain/optimisation mods (verified with Better MC / ATM10) |
