Anyone know how I can make a gameobject fade out smoothly? (C# script)

I’ve tried this but I don’t know what to do after writing the actual code and assigning it to the gameobject I want to fade out.

using UnityEngine;
using System.Collections;

public class fader : MonoBehaviour {

private Color thisColor;
public bool destroyOnFaded=true;
private bool isFading = false;
private Color col = new Color();

// Use this for initialization
void Start () {
	thisColor = renderer.material.GetColor("_Color");
	col.r = thisColor.r;
	col.g = thisColor.g;
	col.b = thisColor.b;
	col.a = thisColor.a;
	isFading = true;
}

// Update is called once per frame
void Update () {
	if(isFading){
	col.a=-0.99f;//-= 0.5f * (float)Time.deltaTime;
	renderer.material.SetColor("_Color", col);		
	}
}

}

Use iTween’s FadeTo.

iTween

And make sure the shader you are using have transparency.

Ok, thanks for the help guys.
