Shoot Timer Wont Reset

Question

 if (Input.GetKey(KeyCode.Space))
         {
             timer -= Time.deltaTime;
             if (timer < 0)
             {
                 Rigidbody bull = (Rigidbody)Instantiate(bullet, transform.position, transform.rotation);
                 bull.AddForce(Vector3.forward * 10f);
                 timer = 5f;
             }
         }

This has me stumped. Wondering why my timer isn't resetting to 5 after I shoot? Is there something wrong with my logic?

Thanks!

Okay, weird. I found the problem.

                  if (timer < 0)
                  {
                      Rigidbody bull = (Rigidbody)Instantiate(bullet, transform.position, transform.rotation);
                      bull.AddForce(Vector3.forward * 10f);
                      timer = 5f;
                  }

Unity doesn't read anything after:

   bull.AddForce(Vector3.forward * 10f);

I changed it to:

                  {
                      timer = 5f;
                      Rigidbody bull = (Rigidbody)Instantiate(bullet, transform.position, transform.rotation);
                      bull.AddForce(Vector3.forward * 10f);
                  }

and now it works fine. Why is this? Is it a bug? (I am using 5.3.1 because too lazy to update right now)

Also throws an InvalidCastException at the force line. Maybe this is a breakpoint for the code? But it still works? So odd

Maybe try :

 Rigidbody bull = Instantiate(bullet, transform.position, transform.rotation).GetComponent<Rigidbody>();

Yeah that explains it, after an error the script stops to execute. Vintar is right, use GetComponent, or if the object doesn't already have one, AddComponent.
