Andengine Collisions - исключение при обнаружении столкновений и удалении тел

Question

Я работаю над игрушкой boxbox. Когда я пытаюсь удалить столкновенные тела со сцены несколько раз после ошибки. Похоже, это случайная ошибка.

Uncaught handler: thread GLThread exiting due to uncaught exception 
java.lang.IndexOutOfBoundsException: Invalid location 48, size is 48

Answer 1

Вы удаляете корпус в потоке пользовательского интерфейса. Это означает, что когда сцена рисуется, она пытается нарисовать то, что больше не привязано к сцене, и вы получаете исключение ArrayIndexOutOfBoundsException. Если вместо runOnUiThread вы используете runOnUpdateThread, у вас не должно быть проблем.
