        }

        UpdateCharacter(selectedOption);
    }

    private void UpdateCharacter(int selectedOption)
    {
        Character character = characterDB.GetCharacter(selectedOption);
        artworkSprite.sprite = character.characterSprite; <-- where the error is
        nameText.text = character.characterName;
    }
}

CodePudding user response：

you can use 2 ways to set sprite

 artworkSprite = character.characterSprite;

or

public Image artworkImage;
...
artworkImage.sprite = character.characterSprite;

I hope it will work on your project.
