Question by ei2014 · Jan 29 at 05:58 PM · boxcollider2d

How do I make multiple of the same colliders for a gameobject (2D),

Basically, I'm trying to make an enemy that uses two box colliders.

What I've done is made a child object to the enemy that has it's own script and it's own box collider, and it worked out well. The problem with this was that when I tried to make a second enemy using that enemy prefab, both enemies seemed to be using the same instance of the child script (was broken). This is what my code looks like:

Enemy:

 using System;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Enemy : MonoBehaviour
 {
     [SerializeField] float enemyRunSpeed = 5f;
 
     Rigidbody2D enemyRigidBody;
     bool flipIt;
 
     // Start is called before the first frame update
     void Start()
     {
         
         enemyRigidBody = GetComponent<Rigidbody2D>();
     }
 
     // Update is called once per frame
     void Update()
     {
         flipIt = false;
         flipIt = FindObjectOfType<Parascope>().FlipSprite();
 
         if (flipIt)
         {
             FlipSprite();
             FindObjectOfType<Parascope>().SetCollison(false);
         }
 
         if (IsFacingLeft())
         {
             enemyRigidBody.velocity = new Vector2(-enemyRunSpeed, enemyRigidBody.velocity.y);
         } else
         {
             enemyRigidBody.velocity = new Vector2(enemyRunSpeed, enemyRigidBody.velocity.y);
         }
         
     }
 
     private void OnTriggerExit2D(Collider2D collision)
     {
         
     }
 
     private void FlipSprite()
     {
         transform.localScale = new Vector2(Mathf.Sign(enemyRigidBody.velocity.x), enemyRigidBody.transform.localScale.y);
         
         
     }
 
     private bool IsFacingLeft()
     {
         return transform.localScale.x > 0;
     }
 }

Enemy Child Box Collider

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Parascope : MonoBehaviour
 {
     BoxCollider2D parascopeCollider;
 
     bool collisionIsTrue = false;
 
     // Start is called before the first frame update
     void Start()
     {
         parascopeCollider = GetComponent<BoxCollider2D>();
     }
 
     // Update is called once per frame
     void Update()
     {
         print(collisionIsTrue);
     }
 
     public void SetCollison(bool value)
     {
         collisionIsTrue = value;
     }
 
     private void OnTriggerExit2D(Collider2D collision)
     {
         collision = parascopeCollider;
         collisionIsTrue = true;
         FlipSprite();
         
     }
 
     public bool FlipSprite()
     {
         return collisionIsTrue;
         
     }
 }
 

I'm very new to unity, and I'm using unity 2021 and 2d. Please help me :)
