why isn't my enemy shooting at me
I am making a fps and my enemy isn't shooting at me. all variables are assigned, they just walk up to me and stand there. is there any reason the player doesn't receive the raycast? I can shoot them just fine here are scripts.
enemy
using UnityEngine; using UnityEngine.AI;
[RequireComponent(typeof(NavMeshAgent))] [RequireComponent(typeof(Rigidbody))]
public class SC_NPCEnemy : MonoBehaviour, IEntity { public float attackDistance = 3f; public float movementSpeed = 4f; public float npcHP = 100; //How much damage will npc deal to the player public float npcDamage = 5; public float attackRate = 0.5f; public Transform firePoint; public GameObject npcDeadPrefab;

public Transform playerTransform;

public SC_EnemySpawner es;
NavMeshAgent agent;
float nextAttackTime = 0;
Rigidbody r;
// Start is called before the first frame update
void Start()
{
agent = GetComponent<NavMeshAgent>();
agent.stoppingDistance = attackDistance;
agent.speed = movementSpeed;
r = GetComponent<Rigidbody>();
r.useGravity = false;
r.isKinematic = true;
}
// Update is called once per frame
void Update()
{
if (agent.remainingDistance - attackDistance < 0.01f)
{
if (Time.time > nextAttackTime)
{
nextAttackTime = Time.time + attackRate;
//Attack
RaycastHit hit;
if (Physics.Raycast(firePoint.position, firePoint.forward, out hit, attackDistance))
{
if (hit.transform.CompareTag("Player"))
{
Debug.DrawLine(firePoint.position, firePoint.position + firePoint.forward * attackDistance, Color.cyan);
IEntity player = hit.transform.GetComponent<IEntity>();
player.ApplyDamage(npcDamage);
}
}
}
}
//Move towardst he player
agent.destination = playerTransform.position;
//Always look at player
transform.LookAt(new Vector3(playerTransform.transform.position.x, transform.position.y, playerTransform.position.z));
//Gradually reduce rigidbody velocity if the force was applied by the bullet
r.velocity *= 0.99f;
}
public void ApplyDamage(float points)
{
npcHP -= points;
if (npcHP <= 0)
{
//Destroy the NPC
GameObject npcDead = Instantiate(npcDeadPrefab, transform.position, transform.rotation);
//Slightly bounce the npc dead prefab up
npcDead.GetComponent<Rigidbody>().velocity = (-(playerTransform.position - transform.position).normalized * 8) + new Vector3(0, 5, 0);
Destroy(npcDead, 10);
es.EnemyEliminated(this);
Destroy(gameObject);
}
}
} player health, (called damage reciever)

I solved it, turns out I only needed to put player tag on player object.
