Can't get health bar vertical in OnGui in C#

Can't get health bar vertical in OnGui in C#.... we tried google and endless amount of time researching how to get our current health bar vertical instead of horizontal.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class AirBar : MonoBehaviour {
5.  
6.     public float air = 10;
7.     public float maxAir = 10;
8.     public float airBurnRate = 1f;
9.     public Texture2D bgTexture;
10.     public Texture2D airBarTexture;
11.     public int iconWidth =32;
12.     public Vector2 airOffset = new Vector2(10, 10);
13.  
14.     private GameObject Player;
15.  
16.     // Use this for initialization
17.     void Start () {
18.  
19.         Player = GameObject.FindWithTag("Player");
20.    
21.     }
22.  
23.     void OnGUI(){
24.  
25.         var percent = Mathf.Clamp01 (air / maxAir);
26.  
27.         if (!Player)
28.             percent = 0;
29.  
30.         DrawMeter (airOffset.x, airOffset.y, airBarTexture, bgTexture, percent);
31.  
32.     }
33.  
34.     void DrawMeter(float x, float y, Texture2D texture, Texture2D background, float percent){
35.  
36.         var bgW = background.width;
37.         var bgH = background.height;
38.  
39.         GUI.DrawTexture (new Rect (x, y, bgW, bgH), background);
40.  
41.         var nW = ((bgW - iconWidth) * percent) + iconWidth;
42.  
43.         GUI.BeginGroup (new Rect (x, y, nW, bgH));
44.         GUI.DrawTexture (new Rect (0, 0, bgW, bgH), texture);
45.         GUI.EndGroup ();
46.  
47.  
48.     }
49.  
50.     // Update is called once per frame
51.     void Update () {
52.  
53.         if (!Player)
54.             return;
55.  
56.         if (air > 0) {
57.             air -= Time.deltaTime * airBurnRate;
58.  
59.         } else {
60.             LevelManager script = Player.GetComponent<LevelManager> ();
61.             script.StopLevel();
62.         }
63.     }
64. }
65.  

 

Line 43 can just be

Code (CSharp):

1.   GUI.BeginGroup (new Rect (x, y, bgW, bgH*percent));

for top to bottom
Its a little more complicated for bottom to top (Typed here and now, not tested, and mostly guessworked)

Code (CSharp):

1. float dY = bgH * (1-percent);
2. GUI.BeginGroup(new Rect(x, y + dY, bgW, bgH * percent));
3. GUI.DrawTexture(new Rect(0, -bgH * percent, bgW, bgH), texture);
4. GUI.EndGroup();

 

Thanks a lot for your answer, however the bar just disappeared when I tested the code.

 

Ah, see the mistake is that you should be using Unity 4.6+ UI.

Problem solved.
