Building Structures

Primary Method: Schematics

Use build_schematic() for all structures. See building-with-schematics skill for schema details.

Critical: Floor Y = Ground Y

Floor REPLACES ground, NOT sits on top!

WRONG: Y=65 floor, Y=64 foundation, Y=63 grass (elevated!)
RIGHT: Y=65 walls, Y=64 floor REPLACES grass, Y=63 dirt

Workflow: get_surface_level(x,z) → anchor at that Y

Pre-Build Checklist

• get_surface_level() called
• anchor_y = ground_y (NOT +1)
• All blocks have orientations
• Doors have lower + upper
• Preview first (preview_only=true)

Building Workflow

# 1. Get ground level
y = get_surface_level(x=100, z=200)

# 2. Design schematic
schematic = {
  "anchor": [100, y, 200],
  "palette": {
    "S": "stone_bricks",
    "P": "oak_planks",
    "W": "oak_planks",
    "G": "glass_pane",
    "Dl": "oak_door[facing=south,half=lower]",
    "Du": "oak_door[facing=south,half=upper]",
    "Sn": "oak_stairs[facing=north,half=bottom]",
    "Ss": "oak_stairs[facing=south,half=bottom]",
    ".": "air"
  },
  "layers": [
    # y=0: Foundation/Floor
    {"y": 0, "grid": [
      ["S", "S", "S", "S", "S"],
      ["S", "P", "P", "P", "S"],
      ["S", "P", "P", "P", "S"],
      ["S", "S", "S", "S", "S"]
    ]},
    # y=1-3: Walls
    {"y": 1, "grid": [
      ["W", "W", "W", "W", "W"],
      ["W", ".", ".", ".", "W"],
      ["G", ".", ".", ".", "G"],
      ["W", "W", "Dl", "W", "W"]
    ]},
    # ... more layers
  ]
}

# 3. Preview
build_schematic(schematic=schematic, preview_only=true, description="Cottage")

# 4. Execute
build_schematic(schematic=schematic, description="Cottage")
