Throwing knife goes straight

I have a script to throw my knife forward, and do damage. But when I throw my knife it goes forward, as expected, but I am guessing that the forward isn't changing when I look up and down. For example, if I were to look upwards, it would still go straight, but not where I am looking. It just goes straight in front of my player, not my knife. Can someone help me so it throws correctly? Here is the section of my script that throws the knife: knifeSend.Play(); rb.isKinematic = false; rb.velocity = transform.forward * rbSpeed; yield return new WaitForSeconds(0.5f); FindClosestEnemy(); yield return new WaitForSeconds(0.1f); ReturnKnife();
