Как использовать тип события keydown? В настоящее время курсор курсора в Atom перемещается, когда я нажимаю на стрелку

Question

Я пытаюсь переместить свой ящик в этой простой программе обнаружения столкновений, но не могу его переместить. Вместо этого мой курсор перемещается в редакторе Atom в зависимости от того, на какую стрелку я нажимаю. Если я также использую WASD, вместо редактора он набирает W, A, S, D в редакторе.

## Collision Detection
    ### foods[:] is a copy of the foods list
    ## this is important as if we are removing at the same time of iterating the actual
    ## food list, it would be confusing and ill-advised
    for food in foods[:]:
        if player.colliderect(food):
            foods.remove(food)
    ## Draw food
    for i in range(len(foods)):
        pygame.draw.rect(windowSurface,green, foods[i])
    ## draw window on screen

Ожидаемый результат должен заключаться в том, что черный ящик (игрок) может перемещаться и «есть» пищу. Пока работает только функция щелчка, которая генерирует новые продуктовые ящики. Отказ от ответственности: Этот код основан на книге Аль Суигарта Invent with Python
