GUIText show nothing

I have empty game object. I added Component GUIText to this object. Object is initialized in the C# code on Start(). On Update() I want to set some text. But this text doesn't appear.
DO I need to do something with this component, maybe add some additional component?

Thanks

Code example:

Code (CSharp):

1. private GUIText score;
2.  
3. void Start()
4. {
5. score = GameObject.Find("scoreText").guiText;
6. }
7.  
8. void Update()
9. {
10. score.text = "Hello!";
11. }
12.  

 

It needs to be positioned correctly in viewport space, but overall you'd be better off forgetting about it and using the UI system in Unity 4.6 instead.

Thanks for this info. Actually I was trying to use component Text firstly. But looks like the problem is really in positioning. Because text doesn't appear even if I put some text in Component's property. The width and height of gameobject with Component text is 100x100, font size 14. I don't know what is wrong.
Can You suggest please on what I need to pay my attention?

Thanks
