From EDIT_MESH change something on EDIT_ARMATURE

While I am in mesh edit mode I would like to change bones in the bone edit context.

I have tried to switch context mode and then call the operator three times, which is not great.

  • Call once to leave mesh edit and go to object mode, then select mesh, go to mesh edit mode.
  • Now in edit bone context, call once to do the operation.
  • Now in edit bone context, call again to go to mesh edit mode.
import bpy

armature = bpy.data.armatures['Armature']
print(dir(armature))
bone = armature.bones[0]
mesh = bpy.data.objects['Cube']

def change_position():
    c = bpy.context
    if c.mode != 'EDIT_MESH':
        print('you must be in mesh edit mode')
        return
    
    print('armature', armature.name)
    print('bone', bone.name)
    print('mesh', mesh.name)
    
    # change position of bone
    import random
    bone.head[0] = random.uniform(-1,1)
    
change_position()

Best way is to do this at once. Every hack is welcomed. :slight_smile:
