name: creating-shapes description: Creates procedural and organic shapes in Minecraft using VibeCraft MCP tools. Use when building spheres, domes, cylinders, pyramids, torus, arches, curves, spirals, organic shapes, statues, or any complex geometry that requires procedural generation.

Creating Shapes

MCP Tools

• worldedit_generation - sphere, cylinder, pyramid, cone
• build(code=...) - Python code that generates commands (RECOMMENDED)
• worldedit_deform - Math expressions

build() Code Mode (RECOMMENDED)

Sphere

Copybuild(code="""
commands = []
cx, cy, cz, radius = 105, 70, 205, 10
for x in range(cx - radius, cx + radius + 1):
    for y in range(cy - radius, cy + radius + 1):
        for z in range(cz - radius, cz + radius + 1):
            if ((x-cx)**2 + (y-cy)**2 + (z-cz)**2)**0.5 <= radius:
                commands.append(f'/setblock {x} {y} {z} stone')
""", description="Solid sphere")

Hollow Sphere

Copy# Add: if radius - thickness <= dist <= radius:

Dome (Half Sphere)

Copy# Limit y range: for y in range(base_y, base_y + radius + 1):
# Use: dist = ((x-cx)**2 + (y-base_y)**2 + (z-cz)**2)**0.5

Cylinder

Copybuild(code="""
commands = []
cx, cz, base_y, radius, height = 105, 205, 64, 8, 20
for y in range(base_y, base_y + height):
    for x in range(cx - radius, cx + radius + 1):
        for z in range(cz - radius, cz + radius + 1):
            if ((x-cx)**2 + (z-cz)**2)**0.5 <= radius:
                commands.append(f'/setblock {x} {y} {z} stone_bricks')
""", description="Solid cylinder")
# Hollow: if radius - thickness <= dist <= radius:

Cone

Copy# Per layer: radius = base_radius * (1 - (y - base_y) / height)

Pyramid

Copybuild(code="""
commands = []
cx, cz, base_y, half = 105, 205, 64, 10
for layer in range(half + 1):
    size = half - layer
    for x in range(cx - size, cx + size + 1):
        for z in range(cz - size, cz + size + 1):
            commands.append(f'/setblock {x} {base_y + layer} {z} sandstone')
""", description="Pyramid")

Torus (Donut)

Copybuild(code="""
commands = []
cx, cy, cz, major_r, minor_r = 105, 70, 205, 12, 4
for x in range(cx - major_r - minor_r, cx + major_r + minor_r + 1):
    for y in range(cy - minor_r, cy + minor_r + 1):
        for z in range(cz - major_r - minor_r, cz + major_r + minor_r + 1):
            dist_xz = ((x-cx)**2 + (z-cz)**2)**0.5
            tube_dist = ((dist_xz - major_r)**2 + (y-cy)**2)**0.5
            if tube_dist <= minor_r:
                commands.append(f'/setblock {x} {y} {z} gold_block')
""", description="Torus")

Spiral Staircase

Copy# Use: angle = step * (2 * pi / steps_per_rotation)
# x = cx + cos(angle) * radius, z = cz + sin(angle) * radius
# Facing based on angle quadrant

Arched Bridge

Copy# Use: arc = sin(progress * pi) * arc_height where progress = (x - start) / length

WorldEdit Shapes

Copy/sphere stone 10       # Solid sphere r=10
/hsphere glass 10      # Hollow sphere
/cyl stone 5 10        # Cylinder r=5 h=10
/hcyl glass 5 10       # Hollow cylinder
/pyramid sandstone 15  # Pyramid

Expression Shapes

Copy/generate gold_block (sqrt(x*x+z*z)-12)^2+y*y<16  # Torus
/generate stone (x*x)/100+(y*y)/25+(z*z)/100<1    # Ellipsoid
/generate stone y<sin(x/5)*3+64                    # Sine wave

Code Sandbox Limits

Allowed: for loops, list comprehensions, math ops, math module NOT Allowed: while, def, lambda, imports (except math), try/except Limits: 10,000 commands max, 100,000 iterations max

Distance Functions

Copy# Euclidean (spheres): ((x-cx)**2 + (y-cy)**2 + (z-cz)**2)**0.5
# 2D (cylinders): ((x-cx)**2 + (z-cz)**2)**0.5
# Manhattan (diamonds): abs(x-cx) + abs(y-cy) + abs(z-cz)
# Chebyshev (cubes): max(abs(x-cx), abs(y-cy), abs(z-cz))

Tips

1. Hollow > Solid (fewer blocks)
2. Preview first: build(preview_only=True)
3. Use /fill for rectangular parts
