Destroy by Tag isnt working,Can't Destroy By Specific Tags

Question

Hi!

I'm currently following a tutorial by GamesPlusJames that has a lot of things that don't work, i've found fixes for everything so far except this; I need to destroy game objects with the tag of 'Enemy' when the 2D box collider of the weapon and the 2D collider of the enemy meet and the code displayed isnt working. The code is attached, the enemies have the 'Enemy' tag and the sword is a trigger so as far as I can tell, everything is how it should be, its just not working. Thank you in advance!

The link to the tutorial

Code:

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class HurtEnemy : MonoBehaviour {

 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
     
 }

 void onTriggerEnter2D (Collider2D other)
 {
     if (other.gameObject.tag == "Enemy")
     {
         Destroy(other.gameObject);
     }
 }

}

The actual problem is that you wrote

 onTriggerEnter2D

instead of

 OnTriggerEnter2D

Unity picks up the methods case sensitive through reflection.

Hello there,

@ShadyProductions above is right. Your method name should be "OnTriggerEnter2D" with a capital O, and not "onTriggerEnter2D".

Also, as a general rule of thumb, you should try putting Debug.Log() everywhere, and tell us which ones get triggered and which ones don't. That way we can deter$$anonymous$$e where the problem occurs, and help you more efficiently :).

Hope that helps!

Cheers,

you have to add Rigidbody2D component to your weapon or your enemy for this OnTriggerEnter2D method to work.

One day, I've got similar problem and in my case it was enough to replace:

 if (other.gameObject.tag == "Enemy")

with:

 if (other.gameObject.CompareTag("Enemy"))

Destroy by Tag isnt working,Can't Destroy By Specific Tags
