I have a bone with various custom properties and I want to change the value of all of them, from 0 to 1 at the same time (pressing a button).


Have a look at the operator simple template in the text editor. Replace main(context) with this

def main(context):
    #active pose bone
    pb = context.active_pose_bone
    # all custom properties on bone
    for key in pb.keys():
        #ignore _RNA_UI
        if key == '_RNA_UI':
        pb[key] = 1
        # insert a keyframe
        pb.keyframe_insert('["%s"]' % key)

and the poll method to

def poll(cls, context):
    return context.active_pose_bone is not None

to make sure that there is an active pose bone selected.

and change the idname from object.simple_operator to something meaningful like posebone.set

Then have a look at the panel simple template and


will give you a UI button.

  • $\begingroup$ how can I insert a keyframe to all of them, using this method? $\endgroup$ – nexxio Jun 7 '16 at 21:18
  • $\begingroup$ @nexxio Added pb.keyframe_insert('["%s"]' % key) to code. Will add a keyframe for each custom property at the frame of button press. $\endgroup$ – batFINGER Jun 8 '16 at 5:17
  • $\begingroup$ thanks a lot! @batFINGER ...and, I wanted this operator duplicated so I could have and operator for 3 more buttons that will make the same but each one will add a new value for one specific custom property. I tested and it works great, but if I copy and paste the script in the same operator simple template and change the idname of the pasted one it does not work. so my question is that: can you have more than one custom operator defined in the same script(I mean something like: custom operators.py)? $\endgroup$ – nexxio Jun 8 '16 at 15:52
  • $\begingroup$ Each operator will also need a new class name eg SimpleOperator2 (think of a better one) and be registered bpy.utils.register_class(SimpleOperator2) in the register method. Could also pass operator arguments look at blender.stackexchange.com/questions/17751/… $\endgroup$ – batFINGER Jun 8 '16 at 16:37
  • $\begingroup$ I did change the class name, and registered and unregistered, but only one works( I just make one copy of the code and pasted it under to see if it works). I thing that maybe is because they both are in main(context): (by the way i dont know what it is for) I tried changin one to: def execute(self, context): but it shows error. $\endgroup$ – nexxio Jun 8 '16 at 19:12
