s&box map support

[izzint]

Whenever I try to load a s&box VPK map file it gives me this error:

seems like it is still not working (used addon from source code instead of releases)

it seems like it is the same error

[REDxEYE]

The map you provided loads fine for me, are you trying to load a different map? If so, can you send it?

[REDxEYE]

Should be fixed now

SBox is constantly updating, they can change anything about map format.
I update sourceio from time to time to support their changes

[PiperManiaDeluxe]

Thanks for the quick reply, would you like more insight on the errors im getting? (even a simple map with a basic mesh and a point light is not importing) or would you like to stop here? I can see how sbox's constant updates can make something like this very frustrating.

[REDxEYE]

You can help by uploading example map

[PiperManiaDeluxe]

Sure!
maps.zip

Importing simpletest.vpk on the main branch gives me the following exception:

Python: Traceback (most recent call last):

And on the better_errors branch:

[REDxEYE]

Interesting, better_errors branch should be the same for parsing code.....

[PiperManiaDeluxe]

Yeah, I've seen that the error the main branch spits out is different on different runs

[REDxEYE]

I think i fixed it, can you please try again?

[PiperManiaDeluxe]

Will do once I can

[PiperManiaDeluxe]

Its not giving me any errors this time but all that gets imported is a single empty with the name of one of the world nodes, no entities or meshes get imported.

[REDxEYE]

It did work for me, could you please share the blend file and logs?
