hm, can't see the image but from your explanation, i guess you mean something like a health bar a lot of rpgs have? like http://jerekdain.com/images/jdhp2.jpg

theres a lot of ways to do it, if you want to use the unityGUI you'd need some textures (background, bars etc) and then use different gui calls in order to get the look, the order you call them is the order they get layered on top of each other.

heres an example, made only one bar for simplicity but you get the idea i hope. http://dl.dropbox.com/u/31075902/stuff/ua/hpbar.png

(c#)

using UnityEngine;
using System.Collections;

public class healthbar : MonoBehaviour 
{
    public int MaxHP = 100;    
    public int HP = 72;
    public string Name = "Character Name";

    void OnGUI()
    {
        // some made up values,  in a real one you'd get them somewhere from your game
        int windowWidth = 200;
        int windowHeight = 80;

        // some made up textures, this part can be removed when you have actual textures for this.
        Texture2D texBG = new Texture2D(1, 1, TextureFormat.ARGB32, true);
        Texture2D texHP = new Texture2D(1, 1, TextureFormat.ARGB32, true);
        Texture2D texHPBG = new Texture2D(1, 1, TextureFormat.ARGB32, true);
        texBG.SetPixel(0, 0, Color.black);
        texBG.Apply();
        texHP.SetPixel(0, 0, Color.red);
        texHP.Apply();
        texHPBG.SetPixel(0, 0, new Color(.3F, .1F, .1F, 1));
        texHPBG.Apply();

        // check to make sure it stays within the maxHP
        if (HP > MaxHP)
            HP = MaxHP;
        if (HP < 0)
            HP = 0;

        // rendering

        // background texture
        GUI.DrawTexture(new Rect(10, 10, windowWidth, windowHeight), texBG, ScaleMode.StretchToFill);

        // name
        GUI.Label(new Rect(100, 12, 100, 30), Name);

        // hp bar background
        GUI.DrawTexture(new Rect(100, 35, MaxHP, 20), texHPBG, ScaleMode.StretchToFill);
        // hp bar current hp
        GUI.DrawTexture(new Rect(100, 35, HP, 20), texHP, ScaleMode.StretchToFill);

        // characters face texture
        GUI.DrawTexture(new Rect(12, 12, (windowHeight - 4), (windowHeight - 4)), texHP, ScaleMode.StretchToFill);  
    }
}

personally though, if you want some complex gui stuff going on, i'd either look into creating your own gui solution with a secondary camera, or look into one of the existing gui systems (like NGUI or EZGUI or alike) in the asset store, as unityGUI is very high with drawcalls and it can also get very messy to setup in more complex systems.

@CanOfColliders the script works but how could i animate it and did you make the gui yourself or like how burgzergarcade did it in there tuorialhere
