Pathlib issue with python 3.6

Think that is fixed in master already, but I'll take a look just in case.

[francoisruty]

cool, many thanks! Do you know when will the next release come out?

[einarf]

Hopefully today. Worst case tomorow. I'll close this issue when the release is out

This looks suspicious. That method is not a static or classmethod. I'm guessing /input/uv.obj will be interpreted as the self argument while the path argument is not properly set.

model = WindowConfig.load_scene("/input/uv.obj")

If you don't use a WindowConfig instance you need to go thought the resources module. I'm still working on docs for that.

from moderngl_window import resources
from moderngl_window.meta import SceneDescription

scene = resources.scenes.load(SceneDescription(path='scenes/crate.obj'))

The load_scene implementation in WindowConfig is probably also a good reference.

If you created your own window and context, also make sure you register it.

moderngl_window.activate_context(ctx=my_moderngl_contect)

And of course also register a search path for your resources

from moderngl_window import resources
resources.register_dir('this/is/where/my/data/is')
resources.register_dir('another/location')

.. because all paths sent to the resource system are relative to one or multiple search paths.

Thanks, so here is what happened.

I was trying to get the example in https://github.com/moderngl/moderngl/blob/master/examples/loading_obj_files.py working. I'm working on a test script so I didn't want the multiple imbricated classes, that's why I didn't have the self argument.

The problem was indeed that:

• I didn't register the resources paths
• I didn't register my opengl context

Many thanks for your help!

[einarf]

Awsome. Will be more docs very soon. That is pretty much pri 1 at the moment 😄

Finally added a section about it here : https://moderngl-window.readthedocs.io/en/latest/guide/custom_usage.html

Be free to yell if you see improvements.
