Airsim: How to obtain the data information of all vehicles in the multi-vehicle state？

[LittleTimeWxk]

Dear friends，
Now I create many cars in simulator and I want to put the datas of them into a list, then I can get the information of the car one by one using python API.

 **My Question：How to get the data of all the vehicles created？**

 I don't understand the code structure of vehicle creation in codes, so I won't use it.Could you provide some help？Tutorials, suggestions and ideas are all available！

Most of the APIs take in a vehicle_name parameter, which should be the name specified on the settings
Not passing the parameter uses the first vehicle

Thanks your reply. But I think, may be you can't understand my question.

Well, then maybe you should have explained it better
See the documentation - https://microsoft.github.io/AirSim/multi_vehicle/

Hi! I have read the documentation, but that's not what i want. I want get the status of all the car one-time.
Now my plan is:
step1: I can get the name of all control car, and put it to a list;
step2: I can get the status of the corresponding vehicle by name list, and put status to a new list;
step3: I will post the state list to a ros point.

My problem is I don‘t know how to get all the names of the car in C++ backend in the first step. Because There are many things I don’t understand in the code project.
Could you give me some advice and other ideas?

Well, you're writing the settings file, so you would already know what are the names of the vehicles. An advanced step could be to use a JSON parser and parse the settings yourself.
This does bring up a possibility of adding a new API to give a list of the vehicles, which could be useful especially if and when https://github.com/microsoft/AirSim/pull/2390 gets in (needs update and lots of testing though)
If you're using ROS, have a look at https://microsoft.github.io/AirSim/airsim_ros_pkgs/ also, it might contan what you need
