помогите, никак не могу найти причину проблемы, пишет что
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at package_cl::gl_ship_cl/fn_stage_x_y_ship()
at package_cl::gl_ship_cl/fn_control_ship()
если из класс main удалить, то всё control_bullet = new Control_bullet_cl (gl_ship) нормально, а если оставить, то кораблик перестаёт двигаться и лезет эта ошибка

тут немного больше переменных, код не полный, боюсь если начну сильнее править, допущу ошибку
