* Устранение неполадок RPG-Engine (AS3): фрагмент кода «Несколько уровней» возвращает «нулевой» HitTestObject

* Здравствуйте!
Я работаю над игровым движком с открытым исходным кодом, написанным на AS3
, и пытаюсь продвинуть MC в другую область / уровень ...

* Как это работает / Идея ...
Когда MC получает ключ, он используется для превращения kameHouseLocked в kameHouseOpen. Когда kameHouse настроен на открытие, игрок может удерживать «стрелку вверх» в направлении двери, чтобы продвигаться вперед. У меня есть два способа добиться этого, либо в рамках видеоклипа, либо вызывая любые вторые слои, необходимые слоям на сцену. В настоящее время мой код настроен так, что он не может ссылаться на kameHouse, который необходим для запуска события. Логика работала достаточно хорошо для ключа. Должен ли я убедиться, что на что-то ссылается в рамках видеоклипа? Нужен ли мне независимый фрагмент полностью для обработки столкновений? Буду признателен за любую помощь, я буду признателен вам за любые усилия / участие, заранее спасибо!

* Вывод выплевывает это? 

    TypeError: Error #2007: Parameter hitTestObject must be non-null.
