Question Please help me with this problem!!!!

I am creating a tower defence game and i am creating a turret script:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class Turret : MonoBehaviour
7. {
8.     public LineRenderer laser;
9.     public Transform Head;
10.     public float Enemydistance;
11.     public float range = 15;
12.     public float rotationSpeed = 10f;
13.     public float nearestEnemyDistance;
14.     public GameObject nearestEnemy = null;
15.     public bool targetinRange = false;
16.     GameObject target = null;
17.  
18.     // Start is called before the first frame update
19.     void Start()
20.     {
21.         InvokeRepeating("findEnemy", 0f, 0.5f);
22.     }
23.  
24.     // Update is called once per frame
25.     void Update()
26.     {
27.         if (nearestEnemyDistance <= range)
28.         {
29.             targetinRange = true;
30.         }
31.         if (target = null)
32.         {
33.             return;
34.         }
35.         else if (target != null && targetinRange)
36.         {
37.             Vector3 dir = target.transform.position - transform.position;
38.             Quaternion lookRotation = Quaternion.LookRotation(dir);
39.             Vector3 rotation = Quaternion.Lerp(Head.rotation, lookRotation, Time.deltaTime * rotationSpeed).eulerAngles;
40.             Head.rotation = Quaternion.Euler(0f, rotation.y, 0f);
41.         }
42.     }
43.  
44.     public void findEnemy()
45.     {
46.         GameObject[] enemies = GameObject.FindGameObjectsWithTag("Enemy");
47.         foreach (GameObject Enemy in enemies)
48.         {
49.             nearestEnemyDistance = Mathf.Min(Enemydistance);
50.             Enemydistance = Vector3.Distance(Enemy.transform.position, this.transform.position);
51.             if (Enemydistance <= nearestEnemyDistance)
52.             {
53.                 nearestEnemyDistance = Enemydistance;
54.                 nearestEnemy = Enemy;
55.             }
56.             if (nearestEnemy != null)
57.             {
58.                 target = nearestEnemy;
59.             }
60.             else
61.             {
62.                 return;
63.             }
64.         }
65.     }
66.     void OnDrawGizmosSelected()
67.     {
68.         Gizmos.color = Color.red;
69.         Gizmos.DrawWireSphere(transform.position, range);
70.     }
71. }
72.  

I set the target = nearest enemy but target was null when i hit play.(nearest enemy is not null)
as shown here: Please help me.

 

I didn't really read too much of it, but on line 31 you have

if (target = null)

, which should've thrown an error already. You need two equals signs if you're comparing the two.

On line 49, you have

nearestEnemyDistance = Mathf.Min(Enemydistance)

, which doesn't make sense because you're getting the minimum value of 1 value, so it always returns itself. Why have Mathf.Min() if you're not using it?

Also, can you try an re-explain what your actual problem is, I can't figure it out. Your code is all over the place and I honestly don't know where to start.

 

target should not be null

 

see line 58.

 

it's ok you solved it.thx

 

On line 62, why are you returning? That exits out of the function completely.

 

It’s ok I changed that line right after the post thx
