Raycast and drawray problems

Questions & Answers

Hello…
Im making a FPS on C# and im having some problems with the Raycast.

 Vector3 fwd = direction.transform.position;
            RaycastHit hit;

            if (Physics.Raycast(fwd, transform.forward, out hit)) ;
            {
                Debug.DrawRay(fwd, transform.forward, Color.red, 5F);
                if (hit.transform.gameObject.tag == "Wall")
                {
                    print("HITwall");
                }

                if (hit.transform.gameObject.tag == "Enemy")
                {
                    //print("HITenemy");
                   GameObject.FindWithTag("Enemy").GetComponent<FSMSimples>().DmgOn = true;
                }

The draw should begin at the direction position (the direction is an empty gameobject attached to the gun), but its starting far away from it.

Error

The red line is the draw from the Debug.DrawRay.
Can someone help?? I dont know what to do.
Tnks!

There's a semi-colon after your if. That makes the lines after it not part of the IF, so they always run. If should be spraying errors about "`hit.transform is NULL`" after each miss.

The short red lines are usual. Unlike raycasts, Debug.DrawRay has the direction and distance together (`transform.forward*10` will make a longer line.)

I'd guess the code is otherwise working perfectly, but your `direction` empty is in the wrong spot. Try putting a cube (with no collider) on it, for a visual, or just select it while running in Scene view, or check every rotation while you're running. You might see something with the blue-arrow unexpectedly going down, putting "far forwards" exactly where the red lines are coming from.

[Edit: new from here down] To really go nuts, check whether `direction` is what you think it is (make it a public global & check inspector while running.) Try printing `Debug.Log("fwd="+fwd);` to make sure fwd isn't really underground.

Thanks, I had not seen the semi-colon there.

Now the Direction is selected, and i dont know why the Ray is so far from it.
