Turn Based Movement - Using Movement Points

Hi, I am Fairly New to Coding and Unity and I have been working on this Game for a little While and I have been Stumped with this Particular Problem.

I want to Limit my Gameobjects Movement by Movement Points, so It cant move more than its Movement points, I also want it so it can move Tiny bits inside the Movement Point Range.

Answers in C# Please.

Thanks in Advance for your Answers.

my Attempt At Making it Work

      public float MaxMovementPoints = 10f;
 float TravelCost;
 float MovementPoints;
 string Selected = "Not Selected";
 string Movement = "Not Moving";
 List<Vector3> waypoints = new List<Vector3> ();
 Vector3 mousePos;
 Vector3 MouseClick;
 Vector3 MouseClickFun;

 // Use this for initialization
 void Start ()
 {
     MovementPoints = MaxMovementPoints;
     print ("TravelDistance is in Start Replace ASAP, add it to Refresh or something Similar");
 }
 
 // Update is called once per frame
 void Update ()
 {

     //next turn refresh

     if (Selected == "Is Selected") {



         if (Input.GetMouseButtonUp (1) && Movement == "Not Moving") {

             //Creating the Vector 3 of the Mouse Click

             mousePos = Input.mousePosition;
             mousePos.z = Camera.main.transform.position.y;
             MouseClickFun = Camera.main.ScreenToWorldPoint (mousePos);

             MouseClick = new Vector3 (Mathf.Round (MouseClickFun.x), 0f, Mathf.Round (MouseClickFun.z));

             //Clearing the List if 'a new move Order' had been given Again
             if (waypoints.Count > 0) {
                 waypoints.Clear ();
             }

             //adding to the Position to Waypoints
             waypoints.Add (MouseClick);

             //Setting the Movement State to "Moving"
             Movement = "Moving";

             //Figuring the Travel cost by Distance and Clamping it so it doesnt Go over Max (And Create a Negative with MovementPoints or Under Zero
             TravelCost = Mathf.Clamp (Vector3.Distance (this.gameObject.transform.position, waypoints [0]), 0, MovementPoints);

             //Applies the Travel Cost to Movement Points
             MovementPoints -= TravelCost;

         }

         if (Movement == "Moving") {

             //This Moves the GameObject to the Waypoint 
             transform.position = Vector3.MoveTowards (this.transform.position, waypoints [0], 20*Time.deltaTime);


             //once Reached its Destination Its Ready to Recieve another Order
             if (this.transform.position == waypoints [0]) {
                 print("I Have Reached Mouse Click");
                 Movement = "Not Moving";
             }
         }
     }
 }

 void OnMouseUp ()
 {
     print (Selected);
     Selected = "Is Selected";
 }
