Move Sword(GameObject) along a path with mouse with same speed

I have sword which move along a path made by mouse move. but sword move with the speed of mouse. I want it to move with constant speed or you may add a variable to maintain its speed. Help me in this regard. My code is below

 private var dragging : boolean = false;
 private var moving : boolean = false;
 private var countDrag : int = 0;
 private var countMove : int = 0;
 private var mousePosition : Vector3;
 private var mousePoint : Vector3;
 private var pointCurrent : Vector3;
 private var pointStore : Vector3;
 private var posStoreX : Array = [];
 private var posStoreZ : Array = [];
 private var arrayPathMarker : GameObject[] = new GameObject[40];
 var objectPathMarker : GameObject;
 var score : int = 0;
 var trn : GameObject;
 var rotSpeed: float = 1000;
 static var fireok : boolean = false;
 var firefmpl : firefromplayer;
 var obj1:GameObject;
 var projectile : GameObject;
 var explosioneffect : GameObject;
 var target : Transform;
 var jumpSound : AudioClip;
 
 function Start () {
     dragging = false;
     trn = GameObject.FindWithTag("Score");
 }
 
 function Update () {
     transform.Rotate(0, rotSpeed * Time.deltaTime + 8, 0, Space.World);
     if(fireok == true)
     {
     fire();
     }
 }
 
 function firefromplayer(fire : boolean){
     print("before if working" + fire);
     if(fire == true)
     {
         fire();
     }
 }
 
 function fire(){

         // where did the raycast hit in the world - position of rayhit
         if (dragging) {
         //print ("rayHit.point : " + rayHit.point + " (mousePoint)");
         }
         mousePoint = rayHit.point;
