var AmoebaSocketServer = require("amoeba.io-socket-server");

function Cube() {}

Cube.prototype.move = function(x, y) {

        x: x,
        y: y

var amoeba = new Amoeba();

    url: "http://localhost:8092"
}), function(err, result) {
    if (err) return; //eror here
    //listen event "moved"
    amoeba.path("cube").on("moved", function(data, event, path) {
        $('.cube').css({
            "top": data.y,
            "left": data.x
        });

    // set cube draggable
    $(".cube").draggable({
        drag: function(event, ui) {
            var pos = ui.position;
            amoeba.path("cube").invoke('move', pos.left, pos.top);
