I got my server working properly and even added jumping but how do I make UI hide when looking away?

Here is what I have so far!

How do I make the HealthBars hide when the camera is facing away?
Can you see in the video how they are floating all over the place looking horrible?

Fixed GUI issue with this

Code (CSharp):

1. void OnGUI()
2.     {
3.         InitStyles();
4.  
5.         // Draw a Health Bar
6.         //   Vector3 pos = Camera.main.WorldToScreenPoint(transform.position);
7.        
8.         Vector3 pos = Camera.main.WorldToScreenPoint(transform.position);
9.         if (Vector3.Angle(Camera.main.transform.forward, transform.position - Camera.main.transform.position) < 60)
10.         {
11.             // draw health bar background
12.             GUI.color = Color.grey;
13.             GUI.backgroundColor = Color.grey;
14.             GUI.Box(new Rect(pos.x - 26, Screen.height - pos.y + 20, Combat.maxHealth / 2, 7), ".", backStyle);
15.  
16.             // draw health bar amount
17.             GUI.color = Color.green;
18.             GUI.backgroundColor = Color.green;
19.             GUI.Box(new Rect(pos.x - 25, Screen.height - pos.y + 21, combat.health / 2, 5), ".", healthStyle);
20.         }
21.     }
