Ошибка атрибута: у объекта 'Ball' нет атрибута 'x'

У меня есть ошибка атрибута, которая мешает мне продолжать, кто-нибудь может ее отладить. Я пробовал перемещать вещи в классе мяча, но ничего не сработало. Я застрял.

В коде может быть больше ошибок, я не уверен, когда пытался пропустить ошибку атрибута и добавить другие вещи. Протестируйте со всем кодом.
