Problem with DrawRay and ray.direction

Physics
1

Hey Guys,

Iam in trouble, I have written a script which casts a ray to the Screens middle, where my crosshair is placed.
Sometimes the “Balls” flying exactly to this position and sometimes they’re flying anywhere beside the crosshair. I tried to find the error with Debug.DrawRay in the following Script, but the Ray isnt draw anywhere:

var ammo : Rigidbody;
var gun : Transform;
var ammoSpeed = 500.0; 

function Shoot()
{
	var hit : RaycastHit;
	var ray = camera.main.ScreenPointToRay(Vector3(Screen.width/2, Screen.height/2, 0));
	if(Physics.Raycast(ray, hit, 100))
	{
		Debug.DrawRay(ray.origin, ray.direction * 1000, Color.green);
	}
	
	ammoClone = Instantiate(ammo, gun.position, gun.rotation);
	ammoClone.rigidbody.velocity = ray.direction * ammoSpeed;

could anyone help me outa here?

Okay find it out 1 second after submitting this post -.-

for everyone, this line was missing:

Physics.IgnoreCollision(ammoClone.collider, gun.collider);
