Unexpected end of JSON input

Unexpected end of JSON input

IceAquaria opened this issue 7 years ago · comments

For some reason, when I run server.sh on Windows 10, I'm getting SyntaxError: Unexpected end of JSON input
at JSON.parse ()
at exports.XMLHttpRequest.xhttp.onreadystatechange (Location:\BLAH\xampp\htdocs\BLAH\BLAH\xQube\server\src\index.js:8:29)

Can you PLEASE tell me how to run the server correctly?

Thank You!

Your webserver should be running the /web/ at root level so you're configuration file would be live at (Line 4) http://127.0.0.1/conf/conf.json or http://localhost/conf/conf.json. Line 8 is meant to parse the settings stored in JSON configuration file.

Let me know if you get it working and if you need additional help.

P.S. I am planning to fully rewrite this whole codebase soon, it is very messy and poorly designed.

Where, on your webserver, is the conf/conf.json located?

IceAquaria · Answer 6 · Wed Jan 17 2018 05:38:51 GMT+0800 (China Standard Time)

D:\D_DRIVE_STUFF\xampp\htdocs\LiveLessons\Three.js\xQube\web\conf\conf.json

At what URL do you use to access the home page on your local machine? It would be something like http://localhost/LiveLessons\Three.js\xQube\web\index.php or something similar.

I use a xampp server so localhost/LiveLessons/Three.js/xQube/web would be correct.

Any luck? Thanks bro! :)

Try changing line 4 to http://localhost/LiveLessons/Three.js/xQube/web/conf/conf.json

awesome! it worked! thanks much! Can you please tell me how to add alpha to my player? as in the part of the server where it says ".r", ".g", ".b" I'd like to add ".a" I tried it & I get an error that says: "new RangeError index out of range" in buffer.js.

Thanks alot buddy! :)

You'd need to write the alpha value here like this

msg.setUint8(offset, colorObj.a, true);
offset++;

Then have it read here like this

var a = reader.readUInt8();
...
var rgb = ('rgb(' + r + ',' + g + ',' + b + ',' + a + ')');
...
this.cubeID.a = a;

As far as I know, the existing color library utilized in the source doesn't support RGBA. It supports RGB and hex color values, parsed here.

You'd have to work on this implementation in more detail, I was just providing basic syntax usage.
