Trying to use Resources.LoadAll to change sprite sheets during runtime

Hey Guys,

I'm trying to use a script that a Unity tech showed in a video lecture that allows you to change sprite sheets during runtime (presumably so a character can change clothes or personal items that they might be holding).

The problem is, I can't seem to get it to work. T$$anonymous$$s is the script:

 using UnityEngine;
 using System;
 
 public class ReSkinAnimation : MonoBehaviour 
 {
 
     public string spriteSheetName;
     
     void LateUpdate () 
     {
         var subSprites = Resources.LoadAll<Sprite>("Sprites/" + spriteSheetName);
 
         foreach (var renderer in GetComponentsInC$$anonymous$$ldren<SpriteRenderer>())
         {
             string spriteName = renderer.sprite.name;
             var newSprite = Array.Find(subSprites, item => item.name == spriteName);
 
             if (newSprite)
                 renderer.sprite = newSprite;
         }
     }
     
 }

If anyone has seen t$$anonymous$$s before and knows how it works, could you please show me how t$$anonymous$$s works in an example? More specifically, how does t$$anonymous$$s relate to the game object with the sprite attached?
