Applying lerp to MouseOrbit

Questions & Answers
1

I’m trying to add lerp to the MouseOrbit script that is shipped with Unity. I want to make it so when the mouse button is released the camera progressively returns to a stand still rather than just stopping as soon as the mouse button is released. So far I have managed to make the Speed value lerp as I can see it return to 0 over the given time in the inspector but there is no visible effect in game. I’m assuming there is a conflict between the Speed, Lerp and how the x/y values are mapped to the mouse axis.

Here is my code;

var target : Transform;
var distance = 10.0;
var lerpSpeed = 5.0;
var Speed = 250.0;
//var ySpeed = 120.0;

var yMinLimit = -20;
var yMaxLimit = 80;

private var x = 0.0;
private var y = 0.0;
private var avgSpeed = new Vector3();
private var dragging = false;

@script AddComponentMenu("Camera-Control/Mouse Orbit")

function Start () {

    var angles = transform.eulerAngles;
    x = angles.y;
    y = angles.x;

	// Make the rigid body not change rotation
   	if (rigidbody)
		rigidbody.freezeRotation = true;
}

function Update(){
	if(Input.GetButton ("Fire1"))dragging = true;
	
	if(!dragging){
	        var i = Time.deltaTime * lerpSpeed;
        	Speed = Mathf.Lerp(Speed, 0, i);
	}
}

function LateUpdate () {
    if (target&&Input.GetButton ("Fire1")&&dragging){
    
    	Speed = 250.00;
    
        x += Input.GetAxis("Mouse X") * Speed * 0.02;
        y -= Input.GetAxis("Mouse Y") * Speed * 0.02;
 		
 		y = ClampAngle(y, yMinLimit, yMaxLimit);
 		

        var rotation = Quaternion.Euler(y, x, 0);
        var position = rotation * Vector3(0.0, 0.0, -distance) + target.position;
        
        transform.rotation = rotation;
        transform.position = position;
    }else{
        dragging = false;
        }
}

static function ClampAngle (angle : float, min : float, max : float) {
	if (angle < -360)
		angle += 360;
	if (angle > 360)
		angle -= 360;
	return Mathf.Clamp (angle, min, max);
}

Any help is greatly appreciated.

 }

 public static float ClampAngle(float angle, float min, float max)
 {
     if (angle < -360F)
         angle += 360F;
     if (angle > 360F)

 }

}

this should do it
