NGUI-UILabel의 Effect에서 Shadow와 Outline을 같이 적용하고 싶어서 찾아보고 올려둠.

UILabel에 세 곳에 소스 추가

public class UILabel : UIWidget
{
    ....
    
    [DoNotObfuscateNGUI] public enum Effect
    {
        None,
        Shadow,
        Outline,
        Outline8,
        ShadowAndOutline,	// Add
    }   
    
    ....
    
    /// <summary>
    /// How many quads there are per printed character.
    /// </summary>

    public int quadsPerCharacter
    {
        get
        {
            if (mEffectStyle == Effect.Shadow) return 2;
            else if (mEffectStyle == Effect.Outline) return 5;
            else if (mEffectStyle == Effect.Outline8) return 9;
            else if (mEffectStyle == Effect.ShadowAndOutline) return 9;	// Add
            return 1;
        }
    }
