I need anchor a ui element to a gameobject like bellow. There was a feature like this on NGUI.

I made a workaround here is the code.
public static Vector3 GetScreenPosition(Transform transform,Canvas canvas,Camera cam)
{
Vector3 pos;
float width = canvas.GetComponent<RectTransform>().sizeDelta.x;
float height = canvas.GetComponent<RectTransform>().sizeDelta.y;
float x = Camera.main.WorldToScreenPoint(transform.position).x / Screen.width;
float y = Camera.main.WorldToScreenPoint(transform.position).y / Screen.height;
pos = new Vector3(width * x - width / 2, y * height - height / 2);
return pos;
}
Use a world space canvas that is a child of the GameObject.
But i will tween this Text to score label. When player gets score/coin it will be shown above of player then it will tween to score label.
This is how NGUI is working http://www.youtube.com/watch?v=lwAT8IO8v0I&list=UUQGZdUwzE8gmvgjomZSNFJg#t=449
If you want to do it the way NGUI does then I suggest you use NGUI.
Unity UI system currently does not have this functionality. The way you attach a UI element to a GameObject is by parenting. You could also create a script of your own to duplicate this functionality.
