Question by Sigillimus · Apr 27, 2016 at 02:46 AM · raycastingdebugdrawline

My RayCast isn't facing forward

Currently there is a script which references the position of an invisible GameObject at the front of the muzzle, and draws a ray from its position. It's supposed to draw it forward, but for some reason when I execute my code:

 private GameObject muzzle;
 
 void Start () {
         muzzle = GameObject.Find("pistol_BulletSpawner");
 }
 
 void Update {
         Debug.DrawLine(muzzle.transform.position, 
                        muzzle.transform.TransformDirection(Vector3.forward), Color.blue);
 
 }

It points down and to the right, like this: alt text

Kind of solved my own issue. Apparently Debug.DrawLine doesn't operate in the same way that Debug.DrawRay does - which seems obvious, but I didn't think of it at the time. That being said, I've found that using '.TransformDirection(Vector3.forward)' with Debug.DrawRay points to the right, rather than forward. I had to use Vector3.left instead, which seems to work - still not sure what's causing that.
