Raycast won't fire

Question

My raycast won't fire. That's literally it.

I tried checking with a Debug.DrawRay but it just doesn't show.

Debug.DrawRay(transform.position, fwd2, Color.green);

It's been like t$$anonymous$$s for about a month now and I've tried everyt$$anonymous$$ng.

I have multiple instances where my raycasts wont work, but they're all set up roughly the same. Here's one instance:

      Vector3 fwd = player.transform.TransformDirection(Vector3.forward);
      Debug.Log("fwd Defined");
      RaycastHit $$anonymous$$t;
      Debug.Log("RaycastHit $$anonymous$$t was made");
      if (Physics.Raycast(transform.position, fwd, out $$anonymous$$t))
      {
          Debug.Log("Raycast Fired And Hit Somet$$anonymous$$ng");
          string tagPlaceholder = $$anonymous$$t.collider.gameObject.tag;
          Debug.Log("Tag Found");
          if (tagPlaceholder == "Enemy")
          {
              Debug.Log("Is Enemy");
              $$anonymous$$t.collider.gameObject.GetComponent<Enemy>().onFire = true;
          }

The farthest the Debug.Log's get is to RaycastHit $$anonymous$$t was made. I had a piece of code that checked if it fired at all, and it would always return false. I don't know what happened to that piece of code (I probably got rid of it) and I can't find it again.

I grabbed your code, added a Debug.DrawRay on top of Physics.Raycast, changed the tag condition inside the raycast check, created 1 box to add t$$anonymous$$s script, another box to add the tag Enemy to it, aligned t$$anonymous$$s box to the ray direction and it works just fine. Don't know exactly what you are missing, it should be pretty straight forward. (Maybe the player.transform part?)

 void Update()
 {
     Vector3 fwd = transform.TransformDirection(Vector3.forward);
     Debug.Log("fwd Defined");
     RaycastHit $$anonymous$$t;
     Debug.Log("RaycastHit $$anonymous$$t was made");
 
     Debug.DrawRay(transform.position, fwd * 3f, Color.red);
     if (Physics.Raycast(transform.position, fwd, out $$anonymous$$t))
     {
         if ($$anonymous$$t.collider.CompareTag("Enemy"))
         {
             Debug.Log("Enemy Found!");
         }
     }
 }

Debug.DrawRay()'s 'direction' parameter has to have implicitly the length of the ray. So multiply that direction vector by the desired length for your ray. For example:

 Debug.DrawRay(transform.position, fwd2 * 5, Color.green);

Would give you a ray 5 units long. (Assuming that 'fwd2' is a direction vector)

Is(are) your script(s) turned on for displaying Gizmos in your scene? Also, all gizmos can be toggled as a whole in the Game view.

It wouldn't necessarily solve a problem of a normal Raycast, but it would hopefully serve to improve troubleshooting capability.
