How do i make my enemy AI attack?
So i'm really new and i want that my Enemy would attack me and do a certain amount of damage (would be nice if there was a range and delay)
Here's my Enemy script: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.AI;
public class EnemyAII : MonoBehaviour {
Transform playerTransform;
UnityEngine.AI.NavMeshAgent myNavmesh;
public float checkRate = 0.01f;
float nextCheck;
// Start is called before the first frame update
void Start() {
if (GameObject.FindGameObjectWithTag("Player").activeInHierarchy)
playerTransform = GameObject.FindGameObjectWithTag("Player").transform;
myNavmesh = gameObject.GetComponent<UnityEngine.AI.NavMeshAgent>();
}
// Update is called once per frame
void Update()
{
if (Time.time > nextCheck)
{
nextCheck = Time.time + checkRate;
FollowPlayer();
}
}
void FollowPlayer()
{
myNavmesh.transform.LookAt(playerTransform);
myNavmesh.destination = playerTransform.position;
}
}
And here's my playerHealth script: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.SceneManagement;
public class PlayerHealth : MonoBehaviour { public int maxHealth = 100; public int currentHealth;
public HealthBar healthBar;
// Start is called before the first frame update
void Start()
{
currentHealth = maxHealth;
healthBar.SetMaxHealth(maxHealth);
}
// Update is called once per frame
void Update()
{
if // I don't know what to do here
{
TakeDamage(20);
}
if (currentHealth <= 0)
{
Die();
}
}
void Die()
{
SceneManager.LoadScene(SceneManager.GetActiveScene().name);
}
void TakeDamage(int damage)
{
currentHealth -= damage;
healthBar.SetHealth(currentHealth);
}
}
So basicly i want the enemy do damage until my health bar is at 0.
My answer is completely untested, and might not be very good, but I think I have a solution To cause damage to the player, maybe you could use void OnTriggerEnter(Collider other){}to detect when the enemy makes contact with the player. Then you would need to add a trigger collider around the enemy for the enemy's attack range, so that the player will take damage when in that range. The script could be something like this:
public class EnemyAttack : MonoBehaviour
{
public float enemyCooldown = 1;
public float damage = 1;
private bool playerInRange = false;
private bool canAttack = true;
private void Update()
{
if (playerInRange && canAttack)
{
GameObject.Find("Player").GetComponent<ControllerForPlayer>().currentHealth -= damage;
StartCoroutine(AttackCooldown());
}
}
void OnTriggerEnter(Collider other)
{
if (other.gameObject.CompareTag("Player"));
{
playerInRange = true;
}
}
void OnTriggerExit(Collider other)
{
if (other.gameObject.CompareTag("Player"));
{
playerInRange = false;
}
}
IEnumerator AttackCooldown()
{
canAttack = false;
yield return new WaitForSeconds(enemyCooldown);
canAttack = true;
}
}
Make sure to make the currentHealth variable in the player script public and everything else should work. IMPORTANT: DO NOT forget to add a trigger collider to the enemy to specify it's attack radius.
I really hope this works for you. Please let me know if it does! This was a really fun thing to try and figure out, so thanks for that.
EDIT: I've revised this code a couple of times now, and I can verify that it does indeed work for me, so hopefully it will work for you too.
I get this error: Cannot implicitly convert type 'float' to 'int'. An explicit conversion exists (are you missing a cast?)
i'm trying to fix it.
I change the float damage to int damage. The error is fixed, but i'm not taking damage
I'm so sorry. I didn't attach the script to the enemy xD It works Thanks!!!!!
lol. I did the same thing when I was testing this. I forgot to attach the script to the enemy. I'm glad it works for you!
what to write instead of ? cuz is giving me error on this line pls im really new
