Fede in guitexture

Hello everyone!
help please.
how do I add a fade in a GUITexture!

this in my code:

var Slider : GUITexture;
var Start_Fade : GUITexture;

function Update () 
{
	if (Input.touchCount > 0  Input.GetTouch(0).phase == TouchPhase.Moved  Start_Fade.HitTest (Input.GetTouch(0).position)) 
	{
		Slider.color.a = /*(FadeIn)*/;
		
	}
}

Look at iTween.FadeTo(). I think it could be applied to a guiTexture. If not, one thing to consider is many, if not most people tend to stay away from Unity’s onGui. It is too costly to the engine. Perhaps a second camera and regular 2DTextures will do.

mmm…there is no other way?!

OnGUI doesn’t have anything to do with GUITextures.
