Module Armature

Armature

This module provides access to Armature objects in Blender. These are "skeletons", used to deform and animate other objects -- meshes, for example.

 import Blender
 from Blender import Armature as A
 from Blender.Mathutils import *
 #
 arms = A.Get()
 for arm in arms.values():
   arm.drawType = A.STICK #set the draw type
   arm.makeEditable() #enter editmode

   #generating new editbone
   eb = A.Editbone()
   eb.roll = 10
   eb.parent = arm.bones['Bone.003']
   eb.head = Vector(1,1,1)
   eb.tail = Vector(0,0,1)
   eb.options = [A.HINGE, A.CONNECTED]

   #add the bone
   arm.bones['myNewBone'] = eb
 
   #delete an old bone
   del arm.bones['Bone.002']

   arm.update()  #save changes

   for bone in arm.bones.values():
     #print bone.matrix['ARMATURESPACE']
     print bone.parent, bone.name
     print bone.children, bone.name
     print bone.options, bone.name

       # Adds emptys for every bone in the selected armature, an example of getting worldspace locations for bones.

               if not arm_ob or arm_ob.getType() != 'Armature':
