How to assign Sprite from Script?

Unity Engine
1

Hi All.

I`m using Sprite Packer.

Sprite Packer doesnt work at Resoureces Folder. So We cant use Resources.Load.

I want to assign (or load) sprite from Script.
How to do this?

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

public class LoadSprite : MonoBehaviour {
   private Image m_Image;
   
   [SerializeField] private Sprite[] m_Sprites;
   private int m_CurrentSpriteIndex = 0;
   
   private void Start () {
     m_Image = GetComponent <Image> ();
   }
   
   private void Update () {
     m_CurrentSpriteIndex = m_CurrentSpriteIndex + 1;
     if (m_CurrentSpriteIndex >= m_Sprites.Length) {
       m_CurrentSpriteIndex = 0;
     }

     m_Image.sprite = m_Sprites [m_CurrentSpriteIndex];
   }
}
