I am trying to call onTriggerEnter (onCollisionEnter is also fine) but it doesn’t seem to be working.

I have already checked this answer but still couldn’t solve the issue.

this is my particleCollision code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;
using UnityEngine.EventSystems;

public class ParticleCollision : MonoBehaviour
{
    public UnityEvent onCollect = new UnityEvent();

    void onTriggerEnter(Collision collision)
    {
        Debug.Log("Trigger Succeeded!!!");
        // if (collision.gameObject.tag == "Player")
        // {
            gameObject.SetActive(false);
            onCollect.Invoke();
        // }
    }

    void onCollisionEnter(Collision collision)
    {
        Debug.Log("Collision Succeeded!!!");
        // if (collision.gameObject.tag == "Player")
        // {
            gameObject.SetActive(false);
            onCollect.Invoke();
        // }
    }
}

I tried turning off “is Trigger” and using onCollisionEnter but it still had no reactions.
Is there anything else I could be missing?
