Why my rotation stops in 1 ?

I'm trying to rotate a GameObject with loop infinity but doesn't work, the rotation stops in 1, I'd Like to know how to do the infinity rotation ? thanks

function Update () {

transform.rotation.y = transform.rotation.y + 0.01;

}

function Awake () { transform.rotation = Quaternion.identity; }

If I understand correctly then you want an object to infinitely spin around on the y-axis? If so then use something like this:

var degreesPerSecond : float = 20.0; 

function Update()
{
    transform.Rotate(Vector3.up * degreesPerSecond * Time.deltaTime, Space.Self);
}

This will rotate the object 20 degrees per second. Change the degreesPerSecond var until you get a nice speed.

You're directly modifying the y component of the rotation quaternion, which is NOT and angle. Use this instead:

transform.rotation.eulerAngles.y = transform.rotation.eulerAngles.y + 0.01;
