Get XY Pos of Mouse?

So, I tried getting the XY pos of the mouse on screen like this:

Code (CSharp):

1. RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
2.        
3.         if(hit.collider != null)
4.         {
5.             Debug.Log ("Target Position: " + hit.collider.gameObject.transform.position);
6.             PosXY=new float[]{hit.collider.gameObject.transform.position.x,hit.collider.gameObject.transform.position.y};;
7.         }

However, bith X and Y are 0, and it doesn't log anything. Anybody know why?

 

You are casting the ray along direction (0,0) which doesnt make sense

 

So Vector2.one?

 

I don't know!
Which direction do you want to cast a ray?

 

There is a discussion about this here http://forum.unity3d.com/threads/unity-2d-raycast-from-mouse-to-screen.211708/
