Question Enemy AI Patrol not working properly.

Hi there, I am new to Unity and making a 2D game for my capstone project. I am using an enemy AI patrol C# script with vomit as the attack. It will just flip rapidly and the vomit will not appear. Here is my script and I can include photos if needed. Any help would be appreciated. Thank you.
Enemy Vomit script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class EnemyVomit : MonoBehaviour
6. {
7.     [SerializeField] private MobileHealthController healthController;
8.     [SerializeField] private float vomitDamage;
9.     public float dieTime;
10.     public GameObject diePEFFECt;
11.  
12.     void Start()
13.     {
14.         StartCoroutine(CountDownTimer());
15.     }
16.  
17.     private void OnTriggerEnter2D(Collider2D collision)
18.     {
19.         if (collision.CompareTag("Player"))
20.         {
21.             Damage();
22.         }
23.     }
24.  
25.     void OnCollisionEnter2D(Collision2D collision)
26.     {
27.         Destroy(gameObject);
28.     }
29.  
30.     IEnumerator CountDownTimer()
31.     {
32.         yield return new WaitForSeconds(dieTime);
33.  
34.         Die();
35.     }
36.  
37.     void Die()
38.     {
39.         Destroy(gameObject);
40.     }
41.  
42.     void Damage()
43.     {
44.         healthController.playerHealth = healthController.playerHealth - vomitDamage;
45.         healthController.UpdateHealth();
46.         this.gameObject.SetActive(false);
47.     }
48. }

AI Patrol script:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;

12.     public bool mustPatrol;
13.     private bool mustTurn, canAttack;

17.     public LayerMask groundLayer;
18.     public Collider2D bodyCollider;
19.     public Transform player, attackPos;
20.     public GameObject vomit;
21.  
22.     void Start()
23.     {
24.         mustPatrol = true;
25.         canAttack = true;
26.     }
27.  
28.     void Update()
29.     {
30.         if (mustPatrol)
31.         {
32.             Patrol();
33.         }
34.  
35.         distToPlayer = Vector2.Distance(transform.position, player.position);
36.  
37.         if(distToPlayer <= range)
38.         {
39.             if (player.position.x > transform.position.x && transform.localScale.x < 0 || player.position.x < transform.position.x && transform.localScale.x > 0
40.                 || player.position.x < transform.position.x && transform.localScale.x > 0)
41.             {
42.                 Flip();
43.             }
44.  
45.             mustPatrol = false;
46.             rb.velocity = Vector2.zero;
47.  
48.             if(canAttack)
49.             StartCoroutine(Attack());
50.         }
51.         else

63.         }
64.     }
65.  
66.     void Patrol()
67.     {
68.         if (mustTurn || bodyCollider.IsTouchingLayers(groundLayer))
69.         {
70.             Flip();
71.         }
72.         rb.velocity = new Vector2(walkSpeed * Time.fixedDeltaTime, rb.velocity.y);
73.     }
74.  
75.     void Flip()
76.     {

78.         transform.localScale = new Vector2(transform.localScale.x * -1, transform.localScale.y);
79.         walkSpeed *= -1;

82.     IEnumerator Attack()
83.     {

85.  
86.        yield return new WaitForSeconds(timeBTWAttacks);
87.         GameObject newVomit = Instantiate(vomit, attackPos.position, Quaternion.identity);
88.  
89.         newVomit.GetComponent<Rigidbody2D>().velocity = new Vector2(vomitSpeed * walkSpeed * Time.fixedDeltaTime, 0f);
90.         Debug.Log("Vomit");
91.         canAttack = true;
92.     }
93. }

 

I cant see your Health Controller script but I would assume your issue is in Update on one of the scripts. Have you set break points and stepped through?

Code (CSharp):

1.  void Damage()
2.     {
3.         healthController.playerHealth = healthController.playerHealth - vomitDamage;
4.         healthController.UpdateHealth();
5.         this.gameObject.SetActive(false);
6.     }

I cant see your health controller code but I suspect something in there might be effecting it or a void update on another script is cycling faster then you can see on screen.

Try setting a counter for the health or debugger. Something like:

debug.log("hit"); or debug.log("vomit:" + healthController.playerHealth.ToString); This will help you see if the method is even being called and how fast its being called.

 

Hi there! So since I posted this, I have made a lot of changes I was able to figure out how to fix the movement. (I simply had to change my enemy layer to default. But I am actually having another issue with the same script as well as my PlayerCombat script. I made another post today with scripts attached. Any help would be appreciated.
