Cannot find Player gameobject with "FindWithTag" function

Im trying to create a 2D runner where obstacles are created on the right and them they go to the left of the screen.

One of the obstacles is a Pilar that you need to attack to remove.
When a Pilar is spawned I try to get the player via FindwithTag function.


PILAR FULL CODE:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using DarkTonic.PoolBoss;
5.  
6. public class ObstaclePilar : MonoBehaviour
7. {
8.     public static GameController GameManager;
9.     public static GameObject game;
10.     public static GameObject Player;
11.     Animator anim;
12.  
13.     // Start is called before the first frame update
14.     void Start()
15.     {
16.         anim.GetComponent<Animator>();
17.         game = GameObject.FindWithTag("GameController");
18.         GameManager = game.gameObject.GetComponent<GameController>();
19.         Player = GameObject.FindWithTag("Player");
20.     }
21.  
22.     // Update is called once per frame
23.     void Update()
24.     {
25.        
26.     }
27.  
28.     public void DestroyThis()
29.     {
30.         PoolBoss.Despawn(transform);
31.     }
32.    
33.     private void OnTriggerEnter2D(Collider2D other)
34.     {
35.         if (other.gameObject.CompareTag("Player"))
36.         {
37.             if (other = Player.GetComponent<CircleCollider2D>())
38.             {
39.                 anim.SetBool("Destroy", true);
40.             }
41.  
42.             if (other = Player.GetComponent<CapsuleCollider2D>())
43.             {
44.                 GameManager.PlayerHit();
45.             }  
46.         }
47.     }
48. }

But Im getting a Null Reference and I don't know why, since I already have use the same function to find the game manager and it worked fine.

After that Im trying to check which collider the Pilar had encontered, the body of the player (Capsule) or the attack collider (Circle).

 

Start by debugging the tag of "other" on collision

Code (CSharp):

1. Debug.Log(other.Name) //Check the name of the game object
2. Debug.Log(other.Tag) //Check the Tag of the game object

Also you have the Layer set to Default, is the object you are colliding with set to Default Layer aswell? You want them to be in the same Layer.

 

Did you mean to do:

Code (CSharp):

1. anim = GetComponent<Animator>();

Instead of:

Code (CSharp):

1. anim.GetComponent<Animator>();

 

You probably want a comparison operator ('==') in line 37:

Code (CSharp):

1. if (other == Player.GetComponent<CircleCollider2D>())

Instead of assignment ('='):

Code (CSharp):

1. if (other = Player.GetComponent<CircleCollider2D>())

This doesn't directly explain the second NullReferenceException, I'd expect it to complain about not being able to implicitly convert to type 'bool'.
