Дисплей Pygame не обновляется

Question

Я делаю игру в Pygame, но дисплей не обновляется. Я использую функцию update () и очищаю экран в начале l oop с помощью fill (). Pygame также загружается не очень быстро; Мне нужно нажать «quit» в приложении pygame, как только оно отобразится в запущенных приложениях на моем ma c, чтобы появился экран.

Я подозреваю, что ожидание события или чтение stdin с input() вызывает проблему блокировки. Но в представленном коде призыв к этому закомментирован. На самом деле невозможно знать.

Эта версия кода с воссозданным классом Button работает нормально, но, очевидно, в ней нет ни одного из упомянутых классов.
