Почему значение x моего врага не меняется с 0, даже если оно явно движется?

Question

Я пытался отладить проблему, из-за которой противник не мог стрелять случайно.Я заметил, что врага1.x не двигался от 0. Я не могу понять, почему, потому что он явно движется слева направо по всему экрану.

Я попытался переключитьЗначения .x к врагу1.x в методе Enemyshots.draw (), но это тоже ничего не изменило.дайте мне знать, если вам нужно больше информации.Спасибо
