} else {
Debug.Log("Failed to Initialize the Facebook SDK");
}
}
private void OnHideUnity (bool isGameShown)
{
if (!isGameShown) {
Time.timeScale = 0;
} else {
Time.timeScale = 1;
}
}


List<string> perms = new List<string>(){"public_profile", "email", "user_friends"};


private void AuthCallback (ILoginResult result) {
if (FB.IsLoggedIn) {
var aToken = Facebook.Unity.AccessToken.CurrentAccessToken;
Debug.Log(aToken.UserId);
// Print current access token's granted permissions
foreach (string perm in aToken.Permissions) {
Debug.Log(perm);
}
} else {
Debug.Log("User cancelled login");
}
}

public void LogInButton()
{
FB.LogInWithReadPermissions(perms, AuthCallback);
}
public void LogOutButton()

}
void FriendInfoCallback(IGraphResult result)
{
Debug.Log("hi= "+result.RawResult);
object dataList;
if (result.ResultDictionary.TryGetValue("data", out dataList))
{
var friendsList = (List<object>)dataList;
CacheFriends(friendsList);
Debug.Log("friendsList= "+Friends);

for(int i=0;i < Friends.Count;i++)
{
Debug.Log(Friends[i]);
}
}

}
public static List<object> Friends;
public static Dictionary<string, Texture> FriendImages = new Dictionary<string, Texture>();

private static void CacheFriends (List<object> newFriends)
{
if (Friends != null && Friends.Count > 0)
{
Friends.AddRange(newFriends);
