OnMouseDown is called when the user presses the left mouse button while over the Collider.

This event is sent to all scripts of the GameObject with Collider. Scripts of the parent or child objects do not receive this event.

using UnityEngine;

public class ExampleClass : MonoBehaviour
{
    void OnMouseDown()
    {
        // Destroy the gameObject after clicking on it
        Destroy(gameObject);
    }
}

Note: This function is not called on objects that belong to Ignore Raycast layer.

This function is called on Colliders and 2D Colliders marked as trigger when the following properties are set to true:

- For 3D physics: Physics.queriesHitTriggers

- For 2D physics: Physics2D.queriesHitTriggers

In addition, OnMouseDown can be a coroutine.
