Я пытаюсь создать 2D -массив классов. Под каждым классом 2 массива и их размеры. Этот класс будет дефолт по умолчанию функции BuildhighlightedAttrib (), чтобы быть доступной по всей форме. Я почти уверен, что все делаю правильно, но я продолжаю получать эту ошибку: < /p>
system.nullreferenceexexception: «Справочник по объекту не установлен на экземпляр объекта». воспроизводимый пример. Я получаю ошибку в строке: < /p>
highlightedAttrb[(uint)Role.GOALKEEPER][DEFEND].Key[0] = (uint)Goalkeeping.AERIAL_REACH;
