This fist map is using in big Mac Com with a bigger size. and second Map is display in normal computer . So why my way point is shifted and didnt display in correct order in normal computer, Below is my script. Some1 please help me check it up Please. THx

//mouseclick to add waypoints

    if (Helicopter_Script.flightState == 0)
    {
        if (Input.GetMouseButtonDown(0))
        {
            position = Input.mousePosition;
            if (position != prevMousePosition)
            {
                prevMousePosition = position;

                //Debug.Log("MouseClicked: mousePosition (x) - "+position.x + ", (y) - "+position.y);
                if ((position.x>=20 && position.x<=570) && (position.y>=150 && position.y<=780))
                {
                    if (helicopter.GetComponent( "Helicopter_Script" ).wayPoints.length == 0)
                        GameObject.Find("Home").renderer.enabled = true;
                    if (helicopter.GetComponent( "Helicopter_Script" ).wayPoints.length < maxWaypoints)
                    {        

                        points1.push(position);
                        linePoints = new Vector2 [points1.length + 1];
                        points1.ToBuiltin(Vector2).CopyTo(linePoints,0);
                        linePoints[linePoints.length-1] = points1[0];
                        if (line1 != null) Vector.DestroyLine(line1);
                        line1 = new VectorLine("Line1", linePoints , Color.red, null, 2.0, LineType.Continuous);
                        Vector.DrawLine(line1);

                        mapPosition.z = (position.y - 150) * (3300.656 + 1327.897) / (780 - 150) + (-1327.897);
                        mapPosition.x = (position.x - 20) * (824.0381 + 3285.686) / (570 - 20) + (-3285.686);
        
                        object = "p"+(helicopter.GetComponent( "Helicopter_Script" ).wayPoints.length+1);        
                        GameObject.Find(object).transform.localPosition.x = mapPosition.x;
                        GameObject.Find(object).transform.localPosition.z = mapPosition.z; 
                        GameObject.Find(object).renderer.enabled = true;

                        Helicopter_Script.wayPoints.Push(mapPosition);
                        Helicopter_Script.isNewWayPoint = true;
                        Debug.Log("numWaypont - "+Helicopter_Script.wayPoints.length +", mapPosition - "+mapPosition);
                    }
                }
            }
        }
    }
   
    //draw lines to waypoints
//    pathPoints[pathIndex] = thisTransform.position;
//    pathLine.maxDrawIndex = pathIndex-1;
//    Vector.DrawLine (pathLine);
//    Vector.SetTextureScale (pathLine, 1.0);

The screens may have different sizes, what could produce the difference. The only way to reliably convert mouse positions to world points (and vice versa) is through the use of some specific Camera functions.

Converting a 3D world point to a 2D screen point is easy:

  screenPoint: Vector2 = Camera.main.WorldToScreenPoint(worldPoint);

But converting screen points to the world is more complicated: the 3D conversion of a 2D point results in a line, not a point, thus you must decide somehow which point of this line to use.

In your case, the easiest way is to cast a ray from the mouse position and find the point where it hits the map plane. To do that, you must create an infinite plane aligned to the map, then use plane.Raycast and ray.GetPoint, like this:

  var ray = Camera.main.ScreenPointToRay(Input.mousePosition); // create the ray
  var mapPlane = new Plane(Vector3.up, Vector3(0, 0, 0)); // create the map plane
  var distance = 0;
  mapPlane.Raycast(ray, distance); // get the distance from the ray start
  worldPoint = ray.GetPoint(distance); // return the map point hit by the ray

This code assumes that the plane is horizontal (normal = Vector3.up) and that 0,0,0 is a point of this plane (the plane created is horizontal and infinite, thus only the y coordinate matters in this case).
