Changing the Sprites of a Character in Runtime

Do you have two or more characters in your game with the same structure, animation but you need to change its Sprites to make them look different?

Do you want to change the Sprite of a character in order to change its look, for example, just to change its clothes or objects that it's carrying?

Put this Component into your Character´s GameObject.
In the Inspector, change the spriteSheetName property to the name of your SpriteSheet Asset.
The Spritesheets must have the same "sliced" sprites name, for example: head, body, etc.

   if (newSprite)
    renderer.sprite = newSprite;
