Changing sprite and animation, through script

Question

Hi,
I'm trying to build multiple skins, for the hero character, into my game. I can't really figure out exactly how to do it though.

Basically, the move animation is the same on all of them, so each sprite is a spritesheet with 3 pictures in it. Exactly the same setup for each.

So, can I create a generic animation, that will simply go for the next sprite in the sheet, and re-use that for each "skin"?

Also, how do I set these sprites from script? I've tried various methods but I end up with a blank character, each time.

I've tried various combinations of the following code:

         renderer = GetComponent<SpriteRenderer>();
         
         var spriteName = PlayerPrefs.GetString("Sprite", "flaming");
         var charSprite = Resources.Load("CharAssets/" + spriteName, typeof(Sprite)) as Sprite;
         renderer.sprite = charSprite;

But as mentioned, not much luck. My sprites for the hero character, is in a folder called CharAssets, in the Assets folder.

First of all don't be using Resources.Load and that kinda thing, the solution is simple yet hard... The thing for this is a AnimationControllerOverride,

Create it in the same way as creating an Animator, you should see the option.
Drag the Animator into the Override as the runtimeAnimatorController
Create Default Animations (ie: IDLE, MOVE), they can just be empty animations
Place these defaults into the Animator. (you should now see in the overrideController the names of the normal states.)
Create a scriptableObject to store all of the different skins

script being able to switch skins:

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 
 [CreateAssetMenu (menuName = "Skin", fileName = "New Skin")]
 public class Skin : ScriptableObject
 {
     [SerializeField] AnimationClip idleAnimation = null;
     [SerializeField] AnimationClip movingAnimation = null;
 
     public AnimationClip GetIdleAnimation ()
     {
         return idleAnimation;
     }
 
     public AnimationClip GetMovingAnimation ()
     {
         return movingAnimation;
     }
 }

 [CreateAssetMenu (menuName = "Skin Atlas", fileName = "New Skin Atlas")]
 public class SkinsAtlas : ScriptableObject
 {
     [SerializeField] Skin defaultSkin = null;
     [SerializeField] List<Skin> Skins = new List<Skin> ();
 
     public Skin GetSkinAtIndex (int index)
     {
         if (index < Skins.Count)
         {
             return Skins[index];
         }
         else
         {
             Debug.LogWarning("index is not in range, add more skins or request a lower index");
             return defaultSkin;
         }
     }
 }

 public class Player : MonoBehaviour
 {
     [SerializeField] SkinsAtlas skinAtlas = null;
 
     Animator animator;
     AnimatorOverrideController overrideController;
 
     const string IDLE = "IDLE";
     const string MOVING = "MOVING";
 
     void SetSkinFromAtlas (int index)
     {
         var skin = skinAtlas.GetSkinAtIndex(index);
         SetSkinAnimations(skin);
     }
 
     void SetSkinAnimations (Skin skin)
     {
         animator = overrideController;
         overrideController.animationClips[IDLE] = skin.GetIdleAnimation();
         overrideController.animationClips[MOVING] = skin.GetMovingAnimation();
     }
 }
