Common Patterns Minecraft Character

Create hierarchy

add_group: name="root", origin=[0, 0, 0] add_group: name="body", parent="root", origin=[0, 24, 0] add_group: name="head", parent="body", origin=[0, 24, 0] add_group: name="arm_left", parent="body", origin=[5, 22, 0] add_group: name="arm_right", parent="body", origin=[-5, 22, 0] add_group: name="leg_left", parent="root", origin=[2, 12, 0] add_group: name="leg_right", parent="root", origin=[-2, 12, 0]

Add geometry

place_cube: elements=[{name: "head", from: [-4, 24, -4], to: [4, 32, 4]}], group="head" place_cube: elements=[{name: "body", from: [-4, 12, -2], to: [4, 24, 2]}], group="body" place_cube: elements=[{name: "arm", from: [-1, 0, -1], to: [1, 10, 1]}], group="arm_left" place_cube: elements=[{name: "arm", from: [-1, 0, -1], to: [1, 10, 1]}], group="arm_right" place_cube: elements=[{name: "leg", from: [-2, 0, -2], to: [2, 12, 2]}], group="leg_left" place_cube: elements=[{name: "leg", from: [-2, 0, -2], to: [2, 12, 2]}], group="leg_right"

Smooth Organic Shape create_sphere: elements=[{name: "base", position: [0, 8, 0], diameter: 16, sides: 16}] subdivide_mesh: mesh_id="base", cuts=1

Select and move vertices to shape

select_mesh_elements: mesh_id="base", mode="vertex" move_mesh_vertices: offset=[0, 4, 0], vertices=["top_verts"]

Tips Use list_outline to see current model structure Set group origins at joint/pivot points for animation Use faces=true for auto UV mapping on cubes Create bone hierarchy before adding geometry Use duplicate_element with offset for symmetrical parts Mesh editing is more flexible but cubes are simpler for Minecraft-style models
