Archilogic gltf model can't be loaded in a-frame

问题

I wrote a demo scene on glitch to test my exported gltf model in a-frame, but I am getting an error in the console:

My code

<!DOCTYPE html>

        <a-cursor color="#FAFAFA"></a-cursor>
      </a-camera>
    </a-scene>
  </body>
</html>

The error:

VM1762:1 Uncaught SyntaxError: Unexpected end of JSON input

Source files: Glitch Fiddle with source files

I have a feeling that I am importing the gltf wrongly into glitch or using it the wrong way. Can anybody help me?

回答1:

from what I understand Your .gltf holds references to the .bins and .jpg textures.
Glitch is not that straightforward, and these files are not in one "directory", as You can see, when You get the links.

The error You get is caused by aframe trying to parse a null/nonexistent source file ( bins and jpgs).

I think it may be better if You put these files on Your server, or put it on github if You want (for the directories are straightforward).

You can also change the file paths in the .gltf file like suggested here.
