Ошибка # 2007 в Flash CS5.5

Question

В настоящее время я изучаю создание головоломки с использованием Flash CS5.5 и AS3.0. Я создал головоломку на разных сценах. Однако, когда я тестирую фильм (Ctrl + Enter), он говорит;

TypeError: Error #2007: Parameter hitTestObject must be non-null. 
    at flash.display::DisplayObject/_hitTest() 
    at flash.display::DisplayObject/hitTestObject() 
    at RECOVER_MAIN__fla::MainTimeline/Ent2Frame() 

Что это значит? Как я могу исправить эту ошибку? AS3.0 моей головоломки, как показано ниже. Спасибо.

Answer 1

Если Google об ошибке 2007, вы можете увидеть, что эта ошибка забросил с помощью контейнера displayobject, когда вы пытаетесь получить доступ к чилу, который не существует в родительском контейнере.

Используйте отладочный фильм (ctrl + shift + enter) вместо тестового фильма (ctrl + enter), например, вы можете увидеть строку, где возникла проблема, и получить дополнительную информацию о проблеме.

Когда у вас есть ваша строка, просто проверьте в аргументе hitTestObject, что ребенок, с которым вы пытаетесь пройти, существует, может быть, это просто ошибка ввода.
