В полном тупике, __init__() missing 1 required positional argument

При нажатии на кнопку L Ctrl выбрасывает ошибку. Вроде бы правильно передаю параметры, в чем причина? Понимаю что закидаете помидорами, но подскажите в какую сторону думать.

  File "C:/Users/Andrei/PycharmProjects/educational-tasks/Funny_сrab/funny_crab.py", line 81, in <module>
    shells.append(ammo((round(position_x + widht_object // 2), round(position_y + height_object // 2)), 5, (0, 0, 0), orient))
TypeError: __init__() missing 1 required positional argument: 'orient'
