Raycasting issue

Please also check the video below.

I'm trying to make the player, the origin of the raycast.
When I draw the ray, the origin is the soldier, so it appears to be correct.
But the 0 point is the lower left corner of the screen instead of the player itself.

How can I make the player the zero point please ?

Code (CSharp):

1. void Update () {
2.        
3.         aimFrom.y = player.transform.position.y;
4.         aimFrom.x = player.transform.position.x;
5.  
6.          direction =  (Input.mousePosition - player.transform.position).normalized ;
7.        
8.         Physics2D.Raycast (aimFrom,direction);
9.         Debug.DrawRay(aimFrom,direction);

 

Input.mousePosition is in screen space, whereas player.transform.position is in world space. You need to convert one of the two, usually Input.mousePosition. You can use Camera.ScreenToWorldPoint() to do that.
