select
Type :boolean, default False
select_head
Type :boolean, default False
select_tail
Type :boolean, default False
show_wire

Type :float in [0, inf], default 0.0
use_connect

When bone has a parent, bone’s head is stuck to the parent’s tail

Type :boolean, default False
use_cyclic_offset

When bone doesn’t have a parent, it receives cyclic offset effects

Type :boolean, default False
use_deform

Bone does not deform any geometry

Type :boolean, default False
use_envelope_multiply

When deforming bone, multiply effects of Vertex Group weights with Envelope influence

Type :boolean, default False
use_inherit_rotation

Bone inherits rotation or scale from parent bone

Type :boolean, default False
use_inherit_scale

Bone inherits scaling from parent bone

Type :boolean, default False
use_local_location

Bone location is set in local space

Type :boolean, default False
basename

The name of this bone before any ‘.’ character (readonly)

center

The midpoint between the head and the tail. (readonly)

children

A list of all the bones children. (readonly)

children_recursive

A list of all children from this bone. (readonly)

children_recursive_basename

Returns a chain of children with the same base name as this bone. Only direct chains are supported, forks caused by multiple children with matching base names will terminate the function and not be returned. (readonly)

length
The distance from head to tail,
when set the head is moved to fit the length.
parent_recursive

A list of parents, starting with the immediate parent (readonly)

vector
The direction this bone is pointing.
Utility function for (tail - head)

(readonly)

x_axis

Vector pointing down the x-axis of the bone. (readonly)

y_axis

Vector pointing down the x-axis of the bone. (readonly)

z_axis

Vector pointing down the x-axis of the bone. (readonly)

align_roll(vector)

Align the bone to a localspace roll so the Z axis points in the direction of the vector given

Parameters:vector (float array of 3 items in [-inf, inf]) – Vector
align_orientation(other)

Align this bone to another by moving its tail and settings its roll the length of the other bone is not used.

parent_index(parent_test)

The same as ‘bone in other_bone.parent_recursive’ but saved generating a list.

transform(matrix, scale=True, roll=True)

Transform the the bones head, tail, roll and envelope (when the matrix has a scale component).

Parameters:
  • matrix (mathutils.Matrix) – 3x3 or 4x4 transformation matrix.
  • scale (bool) – Scale the bone envelope by the matrix.
  • roll (bool) – Correct the roll to point in the same relative direction to the head and tail.
translate(vec)

Utility function to add vec to the head and tail of this bone
