Moving an object along a cosine curve...

Hello. I am trying to make an object move along a cosine curve. This first script is one that moves an object along a sine curve (I modified it from something I got on the forums). When I try to modify it again (as seen in the second script), I run into some problems. As of now, if I set the Height variable to 3, the object’s y transform value immediately moves to 3, dips down to -3 and then goes back up. How can I shift the curve so that I can the object stays at 0 at the start, dips down to -3, and then rises back up to 0. I have tried using Mathf.clamp to stop the value from rising past m_centerPosition.y…but it just gets ignored. What am I doing wrong? Thanks.

``````private var m_centerPosition:Vector3;
private var m_degrees:float = 0;
private var m_speed :float = 1.0f;
private var m_period:float = 1.0f;

var Count : float;
var Speed : float;
var Height: float;

function Start (){
//16.7 is the world space that it takes to complete the Count Cycles.
m_period  = 16.7/Count;
m_speed  *= Speed;
m_period /= Speed;
m_centerPosition = transform.position;
}

function Update(){
m_centerPosition.x += Time.deltaTime * m_speed;
var degreesPerSecond:float = 360.0f / m_period;
m_degrees = Mathf.Repeat(m_degrees + (Time.deltaTime * degreesPerSecond), 360.0f);
var offset:Vector3 = Vector3(0.0f, m_centerPosition.y+Height * Mathf.Sin(radians), 0.0f);
transform.position = m_centerPosition + offset;
}

The Cosine Script.
