Bertie Hephaestus Architecture

NeoForge 1.21.1 addon for Forbidden & Arcanus 2.6.1. It makes the Hephaestus Forge multiblock and its usable pedestal positions depend on the forge tier.

Behavior

• Tier 1 keeps Forbidden & Arcanus' native 9×9 base and eight pedestal slots.
• Tiers 2–5 load Minecraft structure templates:
  • hephaestusarchitecture:hephaestus_forge/tier_2
  • hephaestusarchitecture:hephaestus_forge/tier_3
  • hephaestusarchitecture:hephaestus_forge/tier_4
  • hephaestusarchitecture:hephaestus_forge/tier_5
• A higher-tier forge is active only while its tier template matches.
• The one Hephaestus Forge block saved in the template is the anchor.
• Every F&A pedestal saved in the template becomes a legal ritual input position. Pedestals elsewhere cannot feed that forge.
• All four horizontal rotations work. Mirrored layouts are not accepted.
• Structure Void is ignored. Saved air must remain air. Every other block state must match, including directional properties.
• If a higher-tier template is absent or invalid, that tier logs a warning and falls back to the native F&A layout. This keeps development builds playable while the final schematics are still being authored.
• Ritual datapacks may use up to 64 distinct inputs groups instead of F&A's stock limit of eight. An input group's amount may occupy multiple pedestals.

Supplying a tier schematic

The most reliable workflow is to convert each schematic to a vanilla structure template in a temporary creative world:

1. Build the complete tier layout.
2. Put any F&A Hephaestus Forge tier block at its intended center/anchor.
3. Put F&A pedestals at every position that should accept a ritual item.
4. Use Structure Void for positions that must be ignored by validation.
5. Save it with a structure block under the name hephaestusarchitecture:hephaestus_forge/tier_2 (or tier 3–5).
6. Copy the generated NBT into: src/main/resources/data/hephaestusarchitecture/structure/hephaestus_forge/tier_2.nbt.

The generated world file is normally under <world>/generated/hephaestusarchitecture/structures/hephaestus_forge/. Minecraft's generated folder uses structures (plural), while the 1.21.1 datapack resource folder in this project is structure (singular).

Build

The wrapper delegates to the pinned wrapper in the sibling forge-ink project:

gradle build

Output: build/libs/hephaestusarchitecture-0.1.0.jar

Known integration note

Bertie's native EMI category handles variable-size ritual input groups. F&A's optional built-in JEI screen still draws only eight pedestal slots, so rituals with more than eight total displayed items should be viewed through EMI unless that JEI layout is patched separately.
