Sprite to Texture2D

Sprite 轉 Texture2D 程式:

    /// 

    /// sprite to Textrue2D
    /// 
    /// 
    /// 
    Texture2D textureFromSprite(Sprite sprite)
    {
        if (sprite.rect.width != sprite.texture.width)
        {
            Texture2D image = new Texture2D(((int)sprite.rect.width), (int)sprite.rect.height);
            Color[] imageColors = sprite.texture.GetPixels((int)sprite.textureRect.x,
                                                           (int)sprite.textureRect.y,
                                                           (int)sprite.textureRect.width,
                                                           (int)sprite.textureRect.height);
            image.SetPixels(imageColors);
            image.Apply();

            return image;
        } else
            return sprite.texture;
    }
