[x3d-public] Question about a Python and x3d.py Error message

[Bergstrom, Aaron]

I need help troubleshooting a x3d.py error message.

In developing a Python version of the Rawkee X3D exporter plugin for Maya, I am attempting to create nodes that inherit from both the Maya Python API 2.0 and x3d.py

As such, I have a question about python and multiple class inheritance, and an error I am seeing. Admittedly, I am not the strongest Python programmer.

I am getting the following error when I execute the Python code in Maya, and I'm pretty sure I do not of the __init__() function setup correctly.



# Error: TypeError: file C:\Users\user.name\AppData\Roaming\Python\Python311\site-packages\x3d\x3d.py line 14984: Scene.hasChild() missing 1 required positional argument: 'self' #



Can anyone with some Python experience give me an idea of what I am doing wrong here?



Here is the code:

#################################################################
import x3d

import maya.api.OpenMaya as aom
import maya.api.OpenMayaUI as aomui
import maya.api.OpenMayaRender as aomr

# import xmltodict
# import json

class X3DScene (aom.MPxNode, x3d.Scene):
    TYPE_NAME    = "Scene"
    TYPE_ID      = aom.MTypeId(0x00108FFF)
    PROFILE_TYPE = "Full"
    VERSION      = "4.0"

    def __init__(self):
        super(X3DScene, self).__init__()

    @classmethod
    def creator(cls):
        return X3DScene()

    @classmethod
    def initialize(cls):
        cls.x3dDoc = x3d.X3D(profile=cls.PROFILE_TYPE, version=cls.VERSION)
        cls.x3dDoc.Scene = cls
        #######################################################
        # Test dump to make sure the class works as expected
        #print(json.dumps(xmltodict.parse(cls.x3dDoc.XML()), indent=4))
        print(cls.x3dDoc.XML())
