Support for lights attached to vehicles

[Davidsastresas]

I think it would be useful to be able to change the lights attached to vehicles, in order to better estimate simulations when computer vision is involved in a system where it can control lights.

I think I have sorted out how to include permanent lights attached to the player in Unreal, but I don't know how to start attaching that to a connection in Airsim, and thus to the autopilot or software managing the vehicle.

I would not mind to work on this and do a PR, but I would appreciate a couple of hints about where to look in Airsim to make the connection to such element in unreal.

Thanks!

Recently a feature to control lights was added, see #3991, might be useful here
For a quick hack, might be possible to continuously change the pose of the light object as needed to follow the vehicle, using say simSetObjectPose. Better way wold probably be to attach the blueprint to the vehicle itself, but not sure if it would still work through the API

Thank you very much, that is enough for me to keep pulling that string. If I manage to do something nice I will submit a PR about it. Thanks!

Hi @Davidsastresas, you should be able to achieve what you want by adding one of the light components to the desired vehicle blueprint, then wrapping any operations on that light component with a blueprint function that you then call from a newly added API, similar to what @saihv did with the simSetLightIntensity API in #3991

That is amazing, thank you very much for the update. I should be testing this in a custom vehicle very soon. If over the way I do something PR worth I will do my best to prepare it and push it. Thanks!
