Бележки:

  • Имаш сериозни проблеми със спазване на конвенциите по отношение на идентация и подредба на кода. Моля те да ги оправиш преди крайния срок на задачата, защото иначе ще ти взема наказателни точки. Ако трябва, прочети ръководството по стил отново.
  • Можеш да минеш и без Matrix в тази задача, а със сигурност можеш да минеш и без да го monkey-patch-ваш този клас. Ако държиш представянето ти да е двумерен масив, може просто да ползваш списък от списъци. Само че това не е нужно. Помисли дали няма друг по-оптимален начин в Ruby за реализация вътрешното представяне на пано, от масив от масиви. Ruby не е C и има по-удобни структури от данни, които са достъпни дори без require :)
  • Не виждам нужда да извеждаш метод draw_inner_loop, а не просто да ползваш кода му на ред 26 (т.е. "да го inline-неш"). Това е излишно усложнение. Не го ползваш никъде другаде, не помага на четимостта, името му не е добро.
  • Помисли кой трбява да носи отговорността за "рендериране" на пано. Самото пано или рендерера? Помисли кой обект каква отговорност носи. Една основна идея на ОО-програмирането е да разпределиш различните отговорности между различни обекти. Стреми се всеки обект да отговаря за едно конкретно нещо и само за него. Напълно нормално е да имаш голям брой малки обекти в системата, с тясно специализирани отговорности. В момента ползваш класовете за рендериране като кофи за данни, по много неидиоматичен начин. Възползвай се от факта, че са класове и ги натовари с отговорности.
  • Пробвай да напишеш логиката за рендериране с map и join, вместо да буташ резултата в един низ.
  • Все още не си имплементирал методите за равенство и хеш (==, eql? и hash). Пиши ни имейл, ако имаш проблеми с това.
  • if ... then не се ползва, когато имаш многоредов if (ред 61).
  • На ред 83 няма нужда да слагаш Graphics::, тъй като вече си в контекста на този модул. Може само Point.new .... Това важи и за други места по-надолу.
  • Не оставяй коментари или puts в кода си. Вторите нямат място в крайното решение, а в тази задача от първите няма смисъл, ако кодът е написан чисто и ясно.
  • Методи като draw_it, които ползваш само вътрешно в даден клас и не са част от публичния му интерфейс, прави private.

Основното нещо, над което трябва да поработиш, е да си подобриш подредбата на кода. Това е много критично. Искам да си идеален откъм идентация, поставяне на празни редове, интервали, липса на trailing whitespace и прочее. Честно ти казвам, нямам идея как си постигнал тази каша на подредбата. Само погледни как ти изглежда решението в сайта. Ако имаш нужда от помощ с редактора, виж тази тема или пиши във форума.

Следващото нещо, което искам да опиташ да подобриш, са имената на неща. Мисли дали това е най-добрия начин да кръстиш променлива, метод... Дали изразява максимално точно това, което този метод прави, или това, което тази променлива съдържа. Опитай да гледаш от позицията на човек, който вижда този код за пръв път.
