Method Details

clearChildren()

Attemps to remove all the children of this bone. Because each of the children no longer are parented they will be set a root bones in the armature.

clearParent()

Attempts to clear the parenting of this bone. Because the bone is no longer parented it will be set in the armature as a root bone.

getBoneclass()

Get this Bone's boneclass.
Returns:
Enumeration const (string)

getChildren()

Get this Bone's children Bones, if available.
Returns:
list of Blender Bones

getHead()

Get the "head" ending position.
Returns:
list of three floats

getLoc()

Get the location of this Bone.
Returns:
list of three floats

getName()

Get the name of this Bone.
Returns:
string

getParent()

Get this Bone's parent Bone, if available.
Returns:
Blender Bone

getQuat()

Get this Bone's quaternion.
Returns:
Quaternion object.

getRestMatrix(locale='worldspace')

Return a matrix that represents the rotation and position of this bone. There are two types of matrices that can be returned:
  1. bonespace (in the coord. system of parent) or
  2. worldspace (in the coord system of blender).
The rotation will be in either worldspace or bonespace. Translation vectors (row 4) will be the bone's head position (if worldspace) or the difference from this bone's head to the parent head (if bonespace).
Parameters:
locale - possible values are:
  • worldspace (default)
  • bonespace

           (type=string. Values are:)
Returns:
4x4 PyMatrix

getRoll()

Get the roll value.
Returns:
float

Warning: Roll values are local to parent's objectspace when bones are parented.

getSize()

Get the size attribute.
Returns:
list of three floats

getTail()

Get the "tail" ending position.
Returns:
list of three floats

getWeight()

Get the bone's weight.
Returns:
float

hasIK()

Determines whether or not this bone as flaged as IK.
Returns:
true (1) or false (0)

hasParent()

True if this Bone has a parent Bone.
Returns:
true or false

hide()

Hides this bone.

setBoneclass(boneclass)

Set the bones's boneclass.
Parameters:
boneclass - The boneclass of this bone.
           (type=Enumeration constant. See above.)

setHead(x, y, z)

Set the "head" ending position.
Parameters:
x - The new x value.
           (type=float)
y - The new y value.
           (type=float)
z - The new z value.
           (type=float)

setLoc(x, y, z)

Set the new location for this Bone.
Parameters:
x - The new x value.
           (type=float)
y - The new y value.
           (type=float)

           (type=float)

setName(name)

Rename this Bone.
Parameters:
name - The new name.
           (type=string)

setParent(bone)

Set the bones's parent in the armature.
Parameters:
bone - The Python bone that is the parent to this bone.
           (type=PyBone)

setPose(flags, Action)

Set the pose for this bone. The pose will be set at the Scene's current frame. If an action is passed as the optional second parameter the pose will be added as a keyframe to that action. Otherwise a default action will be created an the pose set to it.
Parameters:
flags - expects ROT, LOC, SIZE in a list. Whichever of these is passed the keyframe generated will set information about the rotation, and/or location, and/or size of the bone.
           (type=PyList of enums)
Action - a python action that has either been created or returned from an object
           (type=PyAction)

Set the new quaternion for this Bone.
Parameters:
quat - Can be a Quaternion or PyList of 4 floats.
           (type=Quaternion object or PyList of floats)

setRoll(roll)

Set the roll value.
Parameters:
roll - The new value.
           (type=float)

Warning: Roll values are local to parent's objectspace when bones are parented.

setSize(x, y, z)

Set the new size for this Bone.
Parameters:
x - The new x value.
           (type=float)
y - The new y value.
           (type=float)
z - The new z value.
           (type=float)

setTail(x, y, z)

Set the "tail" ending position.
Parameters:
x - The new x value.

Parameters:
weight - set the the bone's weight.
           (type=float)

unhide()

Unhide this bone.
