Hi
i have a destroy ground which destroy objects hit it , but i want to make exception for some objects or tag the objects i want to destroy , how can i put tags for this code ?

using UnityEngine;
using System.Collections;

public class DestroyGround : MonoBehaviour {


    void OnTriggerEnter2D(Collider2D collisionObject){
            
       
        Destroy (collisionObject.gameObject);
       

       
       
    }
}

note : they are multible objects i want to tag

Is it what you are asking for ?

and to check a tag :

if(collisionObject.CompareTag("YourTag")){
// insert code here
}

PS: I never applied this to 2d games, so I don’t know if it works the same way.

yes but i want to add multible tags not only one

Multiple tags on the same objets?
Compare multiple tags?

Can you provide an example

multiple tags for multible objects :slight_smile:

You can’t have more than one tag per objects.
Unless you create childs with each unique tags under the same parent.

Otherwise, I don’t know how to do what you want.
Sorry.

Do all the objects have scripts attached to them? if so then you can have

void OnTriggerEnter(Collider2D collider)
{
if(collider.gameObject.tag == "ground")
{
Destroy(gameObject);
}
}

Add this in the script of the collider on the objects you want to be destroyed and dont add this on the ones you dont want to be destroyed.

I think this is something you want in your ontriggerenter2D:

if(collider.gameObject.tag == "tagToDestroy1" | collider.gameObject.tag == "tagToDestroy2" /*| etc.*/) {
   //Destroy
} else {
   print("do something else");
}

The | symbol means OR, so you dont need to repeat else if constantly!
