I want to delete all bones in an armature which contain a specific word but I can't figure out how to. This is the script:
import bpy
import fnmatch
ob = bpy.context.object
if ob.type == 'ARMATURE':
armature = ob.data
bpy.ops.object.mode_set(mode='EDIT')
for bone in armature.bones:
if fnmatch.fnmatchcase(bone.name, "something"):
armature.delete(bone)
And returns the error 'Armature' object has no attribute 'delete'. What am I getting wrong?
Firstly, blender tends to use the term remove instead of delete. Secondly, the armature doesn't directly store the bones, they are stored in a collection called edit_bones (at least, they are when you are in Edit Mode, which is what you script does. bones is for Pose Mode/Object Mode, but bones can't be deleted from there).
So, you firstly need to loop over the edit_bones instead of bones and then use remove instead of delete.
for bone in armature.edit_bones:
if fnmatch.fnmatchcase(bone.name, "something"):
armature.edit_bones.remove(bone)
You can easily explore the properties available on the armature using blender's Python Console, typing in your code there and pressing Ctrl+Space to autocomplete:
>>> bpy.data.objects['Armature'].data.

etc.
Using this, you would be able to see there is no delete method.
