Scale Car Speedometer with Screen Size (made by Andeeee)

Question

I find a great Car Speedometer prefab on the Unity 3D forum, made by the administrator, Andeeee.

The thread URL:

http://forum.unity3d.com/threads/63885-Car-speedometer-dial

It works great (thanks to Andeeee), but it will not resize automatically if the screen size changes.

On the forum thread, a guy posted a code to do this, but the needle disappears.

The original code:

How to scale the speedometer automatically if the screen size changes?

Answer 1

the answer acctuially is:

 var dialTex: Texture2D;
 var needleTex: Texture2D;
 var dialPos: Vector2;
 var topSpeed: float;
 var stopAngle: float;
 var topSpeedAngle: float;
 var speed: float;
 
 dialPos.x = 0;
 
 dialPos.y = Screen.height - dialTex.height;
 
 
 function OnGUI() {
     GUI.DrawTexture(Rect(dialPos.x, dialPos.y, dialTex.width, dialTex.height), dialTex);
     var centre = Vector2(dialPos.x + dialTex.width / 2, dialPos.y + dialTex.height / 2);
     var savedMatrix = GUI.matrix;
     var speedFraction = speed / topSpeed;
     var needleAngle = Mathf.Lerp(stopAngle, topSpeedAngle, speedFraction);
     GUIUtility.RotateAroundPivot(needleAngle, centre);
     GUI.DrawTexture(Rect(centre.x, centre.y - needleTex.height / 2, needleTex.width, needleTex.height), needleTex);
     GUI.matrix = savedMatrix;
 }
 function Update() {
       speed = Vector3.Dot(rigidbody.velocity, transform.forward);
     }
     
     function ForwardSpeed() {
 
   return Vector3.Dot(rigidbody.velocity, transform.forward);
 
 }

thx Mander.
