Here’s I’m going to show you steps on how to share your data between scenes in Unity3D

1. In the starting scene make a new empty object and name it GameData.
2. Add a script named GameController with the following content:

   #pragma strict
   
   private var data : Array;
   
   function Awake () {
   	DontDestroyOnLoad (this);
   }
   
   function Start () {
   	data = new Array();
   	
   	GetNewResults();
   }
   
   function GetNewResults(){
   	var www : WWW = new WWW ("http://localhost/check");
   	
   	yield www;// Wait for download to complete
   	
   	var dataJson = JSON.Parse(www.data);
   	var novi = dataJson["data"].Value;
   	data = dataJson["someMoreData"];
   	
   	if (novi == "true"){	
   		Application.LoadLevel(Application.loadedLevel + 1);
   	}
   	else{
   		Debug.Log("false");
   	}
   }
   
   public function getData(){
   	return data;
   }

   The most important part is DontDestroyOnLoad(this) which does not destroy this object once a new scene is loaded.

3. Then, in another scene, in some script do the following to fetch the data:

   var data = GameObject.Find("GameData").GetComponent(GameController).getData();
