在descr_engins.txt里有装填动作
普通风琴炮：
fire Crew_Rear, crew_left, crew_rear
怪受风琴炮
fire Crew_Rear, crew_right_load_3, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_5, crew_rear, crew_left_stoke_2, crew_left_stoke_3cycle, crew_left_stoke_4, crew_rear
弹幕射击
special_fire Crew_Rear, crew_right_load_3, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_4cycle, crew_right_load_5, crew_rear, crew_left_stoke_2, crew_left_stoke_3cycle, crew_left_stoke_3cycle, crew_left_stoke_3cycle, crew_left_stoke_3cycle, crew_left_stoke_3cycle, crew_left_stoke_3cycle, crew_left_stoke_4, crew_rear
所以装填时间神马的都系浮云，真正的时间全花在这些动作上了，结果就算开弹幕大风琴炮的输出其实还不如小风琴炮
