Transparent lines

Help. How I can add opacity control of the lines in this script?

static var lineMaterial : Material; var LineColor : Color; var Linearray : Array; var ZTest = true;

 Linearray = [0,0,0,1,1,1];

 static function CreateLineMaterial() {
 if( !lineMaterial ) {
 lineMaterial = new Material( "Shader \"Lines/Colored Blended\" {" +
 "SubShader { Pass { " +
 " Blend SrcAlpha OneMinusSrcAlpha " +
 " ZWrite Off Cull Off Fog { Mode Off } " + 
 " ZTest Always Cull Off ZWrite Off " +
 " BindChannels {" +
 " Bind \"vertex\", vertex Bind \"color\", color }" +
 "} } }" );
 lineMaterial.hideFlags = HideFlags.HideAndDontSave;
 lineMaterial.shader.hideFlags = HideFlags.HideAndDontSave;
 }
 }

 function OnPostRender() {
 CreateLineMaterial();
 // set the current material
 lineMaterial.SetPass( 0 );
 GL.PushMatrix();
 GL.Begin( GL.LINES );
 GL.Color(LineColor);

 for (i = 0; i &lt;Linearray.length/3 ; i++)
 {

 GL.Vertex(Vector3(Linearray[i*3], Linearray[i*3+1], Linearray[i*3+2]));

 }

 GL.End();

 GL.PopMatrix();

 }
