Mouse Click Position

Hii...I am developing a traveling game. I have to move my flight(Game object) from one point to other point based on the mouse click..My question is how can I identify the co-ordinates of Mouse click position in unity so that i can move my flight to that particular position...

 

you can do a raycast, using ScreenPointToRay

Code (csharp):

1.  
2.     var ray = Camera.main.ScreenPointToRay(Input.mousePosition);
3.     var selected : RaycastHit;
4.  
5.     if (Physics.Raycast(ray, selected))
6.     {
7.         //selected.point is the 3d position of where the mouse is
8.     }
9.
