hello everyone, I'm writing a multiplayer game and my server is using JSON. question: how to parse JSON in coppercube?
In browser or nodejs i can do that:

var json = '{"a": "b"}'; 
JSON.parse(json);

but this code not working in coppercube (error: JSON is undefined), coppercube doesn't API to working with JSON?

Hi,

Coppercube uses pre es-5 version of js, which doesn't have JSON object api yet.

You can use a polyfill. The simplest one would be:

JSON = { 
    parse: function (sJSON) { return eval('(' + sJSON + ')'); }, 
    stringify: function (vContent) { 
        if (vContent instanceof Object) { 
            var sOutput = ''; 
            if (vContent.constructor === Array) { 
                for (var nId = 0; nId < vContent.length; sOutput += this.stringify(vContent[nId]) + ',', nId++); 
                return '[' + sOutput.substr(0, sOutput.length - 1) + ']'; 
            } 
            if (vContent.toString !== Object.prototype.toString) { 
                return '"' + vContent.toString().replace(/"/g, '\\$&') + '"'; 
            } 
            for (var sProp in vContent) { 
                sOutput += '"' + sProp.replace(/"/g, '\\$&') + '":' + this.stringify(vContent[sProp]) + ','; 
            } 
            return '{' + sOutput.substr(0, sOutput.length - 1) + '}'; 
        } 
        return typeof vContent === 'string' ? '"' + vContent.replace(/"/g, '\\$&') + '"' : String(vContent); 
    } 
};

You can also google json2 and json3, I believe, these implementations could also be adapted to use in Coppercube, but the one above usually works for me.
