Hi guys,
I want to do first person shooting mechanism.I want to raycast from my screen center point(exactly cross hair).But i don't know how to get position of screen coordinates to start raycast. Even i tried to get camera target_vector.I am little bit confused to access camera attributes.How can i get target_vector of a camera

Hi Rajesh,

I'm a total Unity noob (I just downloaded it 2 days ago) but I believe this maybe what you are looking for:

Code (csharp):

1. function Update() {
2.     var x = Screen.width / 2;
3.     var y = Screen.height / 2;
4.    
5.     var ray = camera.ScreenPointToRay(Vector3(x, y, 0));
6.     Debug.DrawRay(ray.origin, ray.direction * 1000, Color.yellow);
7. }

or in C#:

Code (csharp):

1.     void Update()
2.     {
3.         int x = Screen.width / 2;
4.         int y = Screen.height / 2;
5.  
6.         Ray ray = camera.ScreenPointToRay(new Vector3(x, y));
7.  
8.         Debug.DrawRay(ray.origin, ray.direction * 1000, new Color(1f,0.922f,0.016f,1f));
9.  
10.     }

Hope it helps.
