Debug.Log("gameName is " + game.GetName());   

Debug.Log ("scorelist"+game.GetScoreList().Count);

foreach(Transform child in FindRankOnGameOver.instance.scroolview.transform)

{

GameObject.Destroy(child.gameObject);

}

for(int i = 0;i < game.GetScoreList().Count; i++)  

{

fbplayer.Add(game.GetScoreList()[i].GetUserName());

// Debug.Log("userName is : " + game.GetScoreList()[i].GetUserName());   

Debug.Log("userName is : " + game.GetScoreList()[i].GetUserName());  

Debug.Log("score value is : " + game.GetScoreList()[i].GetValue());

Transform picture=friendsentry.transform.Find("Image");

Image fbpic=picture.GetComponent<Image>();

www = new WWW(game.GetScoreList()[i].GetFacebookProfile().GetPicture());

fbpic.sprite=Sprite.Create(www.texture,new Rect(0,0,128,128),new Vector2(0,0));

 

 

 

Transform name=friendsentry.transform.Find("Name");

Transform score=friendsentry.transform.Find("Score");

Text fbname=name.GetComponent<Text>();

Text gamescore=score.GetComponent<Text>();

Hi Sourav,

Unity  follows some structure to download image from webUrl in a sprite texture.So whenever you want to download image from web you should use yield return statement like :

WWW www = new WWW(game.GetScoreList()[i].GetFacebookProfile().GetPicture());

yield return www;

For more information you can go through with this Unity Answer.

Let me know if it helps.

Thanks

hi vishnu,
thaks for your response.
i already checked this link (http://answers.unity3d.com/questions/176372/can-coroutines-be-used-in-external-c-dlls.html) but i am not able to solved my  problem. what i have done i created a different script for callback and in the awake function i wrote this
unitycallback api=gameobject.getcomponent<unitycallback>();
and in success i wrote
api.startcoroutines(response);
but this not solved my problem but it increased my getting closed all the time.
please tell me some thing else.
if  i'm doing something wrong then please tell me how to do this
thanks
