Hello wuesugi,

You can access and you can send message to Smartfox Server in javascript. But NetworkController must be in parent folder and You must import smartfox libs.

import SmartFox;
import SmartFoxClientAPI;
import SmartFoxClientAPI.Data; 

Exaple :

import SmartFox;
import SmartFoxClientAPI;
import SmartFoxClientAPI.Data; 

function Start() 

{

            var client : SmartFoxClient ;
            var  data  : SFSObject ;
            data = new SFSObject();
            client = NetworkController.GetClient();

            data.Put("_cmd","c");       // Create message       
            data.Put("name", gameObject.name);          
            client.SendObject(data);
        }

    }

}

Regards
