具体代码为startpoint =carla.Location(x= 44.42400879,y= 7.18429443,z= 0.27530716) endpoint = carla.Location(x= 209.9933594, y= 9.80837036, z= 0.27530716) # 生成NPC车辆 def generate_npc_vehicle(): global blueprint global transform blueprint = world.get_blueprint_library().find("vehicle.tesla.model3") color = random.choice(blueprint.get_attribute('color').recommended_values) blueprint.set_attribute('color', color) blueprint.set_attribute('role_name', 'autopilot') transform = carla.Transform(startpoint) NPC = world.spawn_actor(blueprint, transform) # 已生成车辆 NPC.set_autopilot(True) NPC.apply_control(carla.VehicleControl(throttle=1.0, steer=0.0, brake=0.0, hand_brake=False, reverse=False, manual_gear_shift=False, gear=0)) return NPC def destroy_npc_vehicle(a): a.destroy() # 触发器事件 def on_trigger_begin_overlap(other_actor): global NPC if isinstance(other_actor, carla.Vehicle) and other_actor == NPC: destroy_npc_vehicle(NPC) NPC = generate_npc_vehicle() # 生成触发器 def generate_trigger(): trigger_bp =world.get_blueprint_library().find("sensor.other.obstacle") trigger_transform = carla.Transform(endpoint) trigger = world.spawn_actor(trigger_bp, trigger_transform) trigger.box_extent = carla.Vector3D(1.0,0.1, 0) trigger.listen(lambda event: on_trigger_begin_overlap(event.other_actor)) return trigger # prepare the light state of the cars to spawn light_state = vls.NONE if args.car_lights_on: light_state = vls.Position | vls.LowBeam | vls.LowBeam NPC = generate_npc_vehicle() trigger = generate_trigger()

根据代码，这是一个使用Carla仿真器生成NPC车辆的代码段。首先定义了起点和终点的坐标，然后定义了生成NPC车辆的函数generate_npc_vehicle()，函数内部选择了蓝图为"vehicle.tesla.model3"的车辆，设置了车辆的颜色...

解释这段代码 def _generate_p_q(key_size): p = q = None n_len = 0 while n_len != key_size: p = PaillierKeyGenerator._get_prime_over(key_size // 2) while gmpy2.mod(p, 4) != 3: p = PaillierKeyGenerator._get_prime_over(key_size // 2) q = p while q == p: q = PaillierKeyGenerator._get_prime_over(key_size // 2) while gmpy2.mod(q, 4) != 3: q = PaillierKeyGenerator._get_prime_over(key_size // 2) n = p * q n_len = n.bit_length() return p, q

这段代码实现了生成Paillier加密算法中需要用到的p和q两个大质数的函数。具体解释如下： 1. 首先，函数需要一个参数key_size，表示要生成的p和q的位数之和。 2. 接着，代码定义了p、q和n_len三个变量，n_len表示p和q...

使用函数 # 触发器事件 def on_trigger_begin_overlap(other_actor): global NPC if isinstance(other_actor, carla.Vehicle) and other_actor == NPC: destroy_npc_vehicle(NPC) NPC = generate_npc_vehicle() # 生成触发器 def generate_trigger(): trigger_bp =world.get_blueprint_library().find("sensor.other.obstacle") trigger_transform = carla.Transform(endpoint) trigger = world.spawn_actor(trigger_bp, trigger_transform) trigger.box_extent = carla.Vector3D(3,3,3) trigger.listen(lambda event: on_trigger_begin_overlap(event.other_actor)) return trigger，为什么车辆经过触发器时，并没有被销毁

在你提供的代码中，on_trigger_begin_overlap函数中调用的destroy_npc_vehicle函数和generate_npc_vehicle函数并没有给出具体的实现方式，无法判断是否存在问题。另外，NPC变量也没有在函数中声明，需要在...
