OnMouseDown does not work

Unity Engine
1

I know this is kind of a common issue, and I’ve looked at many other threads about this. I’ve gone over the checklist of potential problems:

  • Made sure the script is attached to the game object I want to be clickable
  • Made sure I have an enabled collider
  • Made sure I have not resized or changed the position of the collider
  • Made sure there are no other colliders in the way.

But still, nothing happens when I click on my object. Below is my code:

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

public class GeoObject : MonoBehaviour {

    public Sprite[] shapes;
    public float delay = 2.0f;
    public bool clicked = false;
    public float switchTime;
    public int spriteIndex = 0;

    // Use this for initialization
    void Start () {
       
        var renderer = GetComponent<SpriteRenderer>();

        // Randomizes the starting shape
        System.Random rand = new System.Random();
        spriteIndex = rand.Next(0, shapes.Length - 1);
        renderer.sprite = shapes[spriteIndex];

    }

    void OnMouseDown()
    {
        Debug.Log("You have clicked the object!");
    }
}

Additionally, as per the advice from another thread, I also attached the following script to an empty GameObject, to get an idea of what was happening when I tried to click on an object:

public class RayCastExample : MonoBehaviour {

    // Use this for initialization
    void Start () {
       
    }
   
    // Update is called once per frame
    void Update () {
        if (Input.GetMouseButtonDown(0))
        {
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            RaycastHit hit;
            if (Physics.Raycast(ray, out hit))
            {
                Debug.Log("Name = " + hit.collider.name);
                Debug.Log("Tag = " + hit.collider.tag);
                Debug.Log("Hit Point = " + hit.point);
                Debug.Log("Object position = " + hit.collider.gameObject.transform.position);
                Debug.Log("--------------");
            }
        }
    }
}

Still, nothing seems to happen when I click. I would really appreciate any help with this.

Thanks in advance!

It works for me with Default layer, one BoxCollider2D, no GUI canvas.
