Convert To UnityScript

How would I convert the following XNA script to UnityScript:

 private Texture2D CreateStaticMap(int resolution)
 {
     Random rand = new Random();
     Color[] noisyColors = new Color[resolution * resolution];
     for (int x = 0; x < resolution; x++)
     for (int y = 0; y < resolution; y++)
     noisyColors[x + y * resolution] = new Color(new Vector3((float)rand.Next(1000) / 1000.0f, 0, 0));
 
     Texture2D noiseImage = new Texture2D(device, resolution, resolution, 1, TextureUsage.None, SurfaceFormat.Color);
     noiseImage.SetData(noisyColors);
     return noiseImage;
 }

I tried but got a handful of errors:

        var resolution : int;

        function Start(){
        	CreateStaticMap();
        }
        
        function CreateStaticMap(){
        var noisyColors : Color[] = new Color[resolution * resolution];
            for(x=0; x<=resolution; x++){
                 for(y=0; y<=resolution; y++){
                      noisyColors[x + y * resolution] = new Color(Vector3(System.Random.Next(1000) / 1000.0, 0, 0));
                 }
            }
            var noiseImage : Texture2D = new Texture2D( //I have no idea what to do now
         }

The conversion to JS is something like below. The Texture2D() in noiseImage declaration seems to have parameters in excess.

function CreateStaticMap(resolution: int): Texture2D
 {
     var rand = new Random();
     var noisyColors: Color[] = new Color[resolution * resolution];
     for (var x = 0; x < resolution; x++)
       for (var y = 0; y < resolution; y++)
         noisyColors[x + y * resolution] = Color(rand.Next(1000)/1000.0, 0, 0);
     // this Texture2D constructor seems to have too many arguments:
     var noiseImage: Texture2D = Texture2D(device, resolution, resolution, 1, TextureUsage.None, SurfaceFormat.Color);
     noiseImage.SetData(noisyColors);
     return noiseImage;
 }
