How to shatter 2d objects without rigidbody?

Questions & Answers
1

Hi! I want to shatter a 2d object, I am looking for options and most of them using shattered prefabs with rigidbodys. But I can’t use rigidbody because my game is top-down so there is no collider under the object and i can’t use gravity.
Is there other options to shatter a 2d object without using rigidbody?

Here is an example script that splits an object into pieces when hitting an object tagged “Bullet”:

using UnityEngine;

public class ShatterGameObject : MonoBehaviour
{
    public GameObject shatteredGameObject;

    private void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Bullet"))
            return;

        var shatteredObj = Instantiate(shatteredGameObject, transform.position, transform.rotation);

        var rigidbodies = shatteredObj.GetComponentsInChildren<Rigidbody2D>();

        foreach (Rigidbody2D rb2d in rigidbodies)
        {
            Vector2 force = rb2d.transform.position - collision.transform.position;
            rb2d.AddForce(force.normalized * 100);
        }

        Destroy(gameObject);
    }
}

(Note: I have increased the LinearDrag value to slow down the shards over time).
