智能车简单代码
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,设置了车辆的颜色和角色名称等属性,然后使用spawn_actor()函数生成车辆对象,将车辆设置为自动驾驶模式,并启动车辆的控制。还定义了一个销毁NPC车辆的函数destroy_npc_vehicle()。接着,定义了一个触发器事件on_trigger_begin_overlap(),当NPC车辆进入触发器范围内时,销毁当前NPC车辆并生成新的NPC车辆。最后,定义了生成触发器的函数generate_trigger(),使用spawn_actor()函数生成触发器对象,并设置触发器的位置、大小等属性,以及监听触发器事件。最后,调用generate_npc_vehicle()和generate_trigger()函数生成NPC车辆和触发器对象。
